How To Research Long Tail Keywords For Google Ads: A Marketer's Guide To Lower Costs And Higher Conversions
Learn how to research long tail keywords for Google Ads to discover high-intent, low-competition search terms that convert at a fraction of the cost of broad keywords.
You just spent $500 in three days on the keyword "running shoes." The dashboard shows 847 clicks. Your heart races as you check conversions: two sales. Two.
The math is brutal. You paid $2.40 per click for traffic that converted at 0.2%. Meanwhile, your competitor down the street is somehow profitable in the same market, running ads you see every day.
Here's what changed everything for one advertiser in this exact situation: they discovered "women's trail running shoes for wide feet size 8." This hyper-specific phrase cost $0.73 per click and converted at 12%. Same product, same landing page, completely different economics.
This is the long-tail keyword paradox. Lower search volume doesn't mean lower value—it means higher intent, less competition, and dramatically better ROI. While everyone fights over "running shoes" at $2+ per click, dozens of specific variations sit waiting at a fraction of the cost, typed by people who know exactly what they want.
The difference between burning budget and building profit often comes down to keyword specificity. Broad terms attract broad audiences with vague intent. Long-tail keywords attract ready buyers who've already done their research and just need to find the right seller.
Think about your own search behavior. When you're just browsing, you type something generic. When you're ready to buy, you get specific: "waterproof hiking boots men size 11 wide," "emergency plumber near me Sunday," "gluten free birthday cake delivery Chicago." That specificity signals intent, and intent is what converts.
By the end of this guide, you'll know exactly how to find these hidden-gem keywords that your competitors are overlooking. You'll learn to think like your customers, uncover the specific phrases they use when they're ready to take action, and build Google Ads campaigns that generate results instead of just traffic.
The process isn't complicated, but it does require a systematic approach. You'll need to look beyond obvious keywords, dig into actual search data, and understand the difference between what you think people search for and what they actually type into Google.
Let's walk through how to do this step-by-step, starting with understanding what makes a keyword "long tail" in the Google Ads context—because it's different from SEO, and that distinction matters for your budget.
Understanding Long-Tail Keywords in Google Ads Context
Long-tail keywords in Google Ads aren't just about word count. They're about specificity, intent, and competition level. A three-word phrase can be highly competitive, while a two-word phrase might be perfectly long-tail if it's specific enough.
The term "long tail" comes from the search demand curve. Head terms like "shoes" get massive search volume but convert poorly. Mid-tail terms like "running shoes" get moderate volume with better intent. Long-tail terms like "women's trail running shoes for plantar fasciitis" get low individual volume but collectively represent the majority of searches—and the highest intent.
In Google Ads, this matters because you're paying per click. A head term might cost you $5 per click with a 1% conversion rate. That's $500 per conversion. A long-tail variation might cost $0.80 per click with an 8% conversion rate. That's $10 per conversion. Same product, 50x difference in acquisition cost.
The key distinction from SEO is immediacy. With SEO, you might target long-tail keywords to rank faster. With Google Ads, you target them to spend less and convert more, right now. You're not waiting for rankings—you're buying traffic, so every click needs to count.
Long-tail keywords in Google Ads typically share these characteristics: they're three or more words, they include specific modifiers (size, color, location, problem), they show clear purchase intent, they have lower search volume (under 1,000 monthly searches), and they face less competition from other advertisers. Understanding how much is google ads for different keyword types helps you budget effectively for long-tail campaigns.
Consider the difference between "CRM software" and "CRM software for real estate teams under 10 people." The first term is broad, expensive, and attracts everyone from students doing research to enterprises comparing vendors. The second term is typed by someone who knows exactly what they need and is ready to evaluate specific solutions.
This specificity creates a filtering effect. You're not paying for tire-kickers. You're paying for qualified prospects who've already self-selected by typing a phrase that matches your exact offering. That's why long-tail keywords often deliver 2-3x higher conversion rates despite lower traffic volume.
Step 1: Start with Seed Keywords and Customer Language
Your research begins with seed keywords—the basic terms that describe your product or service. But here's the critical part: don't start with what you call your offering. Start with what your customers call it.
This distinction matters more than most advertisers realize. You might sell "enterprise resource planning solutions." Your customers search for "inventory management software" or "order tracking system." You might offer "aesthetic dermatology services." They search for "get rid of acne scars" or "reduce wrinkles without surgery."
To capture actual customer language, start with these sources: customer service transcripts (what questions do people ask?), sales call recordings (what problems do they describe?), product reviews on your site and competitors' sites, social media comments and questions, and support ticket subjects. These sources reveal the exact phrases people use when they have the problem your product solves.
Create a spreadsheet with three columns: what you call it, what customers call it, and the problem they're trying to solve. For example, if you sell project management software, your rows might look like this: "Gantt chart software" / "project timeline tool" / "need to show project deadlines to team," or "resource allocation" / "who's working on what" / "can't track team workload."
The problem column is especially valuable because it reveals search intent. People don't always search for solutions—they search for problems. "How to track multiple projects at once" is a long-tail keyword that might never appear in traditional keyword research, but it's exactly what someone types before they're ready to buy project management software.
Talk to your sales team. Ask them: "What do people say they need in the first five minutes of a call?" The answer is usually different from your marketing messaging, and it's gold for keyword research. One SaaS company discovered their best converting keyword was "stop using spreadsheets for inventory" because that's the exact phrase prospects used in sales calls.
Look at your website's internal search data. What are people typing into your search box? These queries reveal what visitors expect to find, and they're often more specific than the keywords that brought them to your site. Someone might click an ad for "email marketing software" but then search your site for "email automation for abandoned carts"—that's your long-tail keyword.
Compile 10-20 seed keywords from this research. These don't need to be long-tail yet—they're starting points. "Running shoes," "project management," "CRM software." You'll expand these into long-tail variations in the next steps, but starting with customer language ensures your expansion goes in the right direction.
Step 2: Use Google Ads Keyword Planner for Initial Expansion
Google Ads Keyword Planner is your primary research tool because it shows actual Google Ads data—search volume, competition levels, and bid estimates. This isn't SEO data; it's advertiser data, which is exactly what you need.
Access Keyword Planner through your Google Ads account under Tools & Settings > Planning > Keyword Planner. If you don't have an active account, you'll need to create one, though you don't need to run campaigns to use the tool. Free accounts get search volume ranges; accounts with active campaigns get exact numbers.
Start with "Discover new keywords." Enter your seed keywords one at a time, not all together. Why? Because Keyword Planner groups suggestions by seed keyword, and entering multiple seeds creates a jumbled list that's harder to organize. Run separate searches for each seed keyword and export the results.
For each seed keyword, Keyword Planner returns hundreds of suggestions. Your job is to filter for long-tail opportunities. Set these filters: average monthly searches between 10 and 1,000 (this captures low-volume, specific terms), competition level to "Low" or "Medium" (avoid fighting established advertisers), and suggested bid under your target CPA (if you can afford $5 per click, filter out $8 suggestions).
Look specifically for keywords with modifiers. These are words that add specificity: location modifiers ("near me," "in Chicago," "Denver area"), problem modifiers ("for beginners," "without experience," "easy to use"), feature modifiers ("with reporting," "includes templates," "mobile app"), price modifiers ("affordable," "under $100," "budget"), and time modifiers ("same day," "emergency," "24 hour").
Export your filtered results to a spreadsheet. Create columns for: keyword, average monthly searches, competition level, suggested bid, and keyword category. The category column is where you'll group similar keywords—all location-based keywords together, all problem-based keywords together, etc. This organization becomes crucial when you're building ad groups.
Pay special attention to question-based keywords. "How to," "what is," "where can I," "why does"—these phrases indicate research intent, but they're not useless. Someone searching "how to remove wine stains from carpet" is a perfect prospect for carpet cleaning services. Question keywords often convert well despite looking informational because they capture people at the problem-awareness stage. Implementing a solid negative keywords list for google ads ensures you filter out truly non-commercial searches while keeping valuable question-based queries.
Don't ignore keywords with low search volume. A keyword showing 20 monthly searches might seem worthless, but remember: that's an average. It might spike to 100 searches during your busy season. Plus, 20 highly specific, high-intent searches can be more valuable than 2,000 broad, low-intent searches. One advertiser found their best ROI came from a keyword with 30 monthly searches that converted at 18%.
Step 3: Mine Competitor Keywords and Ad Copy
Your competitors have already done keyword research. They're actively bidding on terms, testing what works, and optimizing their campaigns. You can learn from their testing without spending the money they spent to figure it out.
Start by identifying your top 5-10 competitors—not just direct competitors, but anyone bidding on keywords you care about. Search your seed keywords in Google and note which companies consistently appear in ads. These are your active PPC competitors, and they're more relevant for this research than your overall market competitors.
Manually search your seed keywords and variations in Google. Use incognito mode to avoid personalized results. Look at the ads that appear and note: what keywords appear in the ad headlines (these are likely in their campaigns), what specific features or benefits they emphasize (these suggest keyword modifiers), what landing page URLs they use (these reveal their campaign structure), and what ad extensions they show (location, callout, sitelink extensions reveal additional keywords).
The ad copy itself reveals keyword strategy. If a competitor's headline says "CRM for Real Estate Agents," they're almost certainly bidding on that exact phrase. If they emphasize "No Credit Card Required" or "Free Trial," they're likely targeting bottom-of-funnel, high-intent keywords where that messaging matters.
Use competitor analysis tools for deeper insights. SEMrush, SpyFu, and iSpionage show you competitors' paid keywords, ad copy history, and estimated budgets. Enter a competitor's domain and export their paid keyword list. Filter for keywords with these characteristics: they're bidding on it consistently (appears in multiple months), it has low to medium competition (you can compete for it), it's specific enough to be long-tail (3+ words with modifiers), and it's relevant to your offering (don't chase keywords just because competitors use them).
Look for gaps in competitor coverage. If you notice competitors bidding heavily on "project management software" but not "project management software for construction," that's an opportunity. Either they haven't discovered it, or they tested it and it didn't work for them—but it might work for you if your product is better suited to that niche. Learning from google ads competitor analysis helps you identify these strategic gaps in the market.
Check competitor landing pages for keyword clues. The page they send traffic to reveals what they're targeting. If their landing page emphasizes "easy setup" and "no technical skills required," they're likely bidding on keywords like "simple project management tool" or "project management for non-technical teams." The landing page copy often contains the exact long-tail phrases they're targeting.
Create a competitor keyword matrix. List competitors across the top, keyword categories down the side, and mark which competitors target which categories. This visual map shows you where competition is heavy (avoid or bid carefully) and where it's light (opportunity zones). If four competitors target "affordable CRM" but none target "CRM for insurance agents," you've found a long-tail opportunity.
Step 4: Leverage Google Search Console and Analytics Data
If you have an existing website with organic traffic, your Search Console and Analytics data contains keyword gold. These tools show you what people actually searched before landing on your site—including long-tail phrases you might never have considered.
In Google Search Console, go to Performance > Search Results. This report shows every query that triggered your site in search results, along with impressions, clicks, and position. Filter for queries where you rank in positions 5-20—these are keywords where you have relevance but not dominance, making them perfect for paid support.
Look specifically for high-impression, low-click queries. If a keyword got 500 impressions but only 10 clicks, it means people are searching for it, seeing your site, but not clicking. This is a perfect candidate for Google Ads. You can bid on that keyword, write compelling ad copy, and capture the traffic you're missing organically.
Export your Search Console query data and filter for long-tail characteristics: 4+ words in the query, fewer than 1,000 monthly impressions (indicates specificity), and click-through rate below your average (opportunity to improve with ads). These queries represent real search demand with proven relevance to your site.
In Google Analytics, check Acquisition > All Traffic > Source/Medium and filter for "google / organic." Then look at the landing pages that get this traffic. Click on a landing page and add a secondary dimension of "Keyword" (though most will show "not provided"). While Google hides most keyword data, you can infer keywords from the landing page content and title.
More valuable: check Behavior > Site Search > Search Terms if you have internal site search enabled. This shows what visitors search for on your site after they arrive. These queries reveal intent and specificity. Someone might land on your homepage via "marketing software," then search your site for "email automation for e-commerce"—that's your long-tail keyword.
Look at your conversion paths. In Analytics, go to Conversions > Multi-Channel Funnels > Top Conversion Paths. This shows the sequence of interactions before conversion. You might discover that people often search a broad term, visit your site, leave, then return days later via a specific long-tail search. That long-tail search is the one to bid on—it's the final step before conversion.
Check your organic landing pages with the highest conversion rates. These pages are already optimized for specific topics, and they're proven to convert. The keywords these pages rank for (visible in Search Console) are excellent candidates for Google Ads campaigns. You're essentially amplifying what already works.
Use the "Queries" report in Search Console to find question-based long-tail keywords. Filter for queries containing "how," "what," "where," "when," "why," or "which." These questions reveal specific problems people are trying to solve, and they're often less competitive than product-focused keywords while still driving qualified traffic.
Step 5: Expand with Keyword Modifiers and Variations
Now you have a solid list of long-tail candidates from Keyword Planner, competitor research, and your own data. The next step is systematic expansion—taking each promising keyword and creating variations that capture different search intents and user contexts.
Start with location modifiers if you serve specific areas. Take a base keyword like "emergency plumber" and add: city names ("emergency plumber Chicago"), neighborhood names ("emergency plumber Lincoln Park"), proximity terms ("emergency plumber near me"), and state or region ("emergency plumber Illinois"). Even if you serve a national market, location-modified keywords often have lower competition and higher intent.
Add problem-specific modifiers. These describe the specific issue someone is trying to solve: "for [problem]" ("CRM for managing leads"), "without [pain point]" ("project management without complexity"), "to [goal]" ("software to track employee time"), and "[problem] solution" ("high employee turnover solution"). These modifiers capture people who are problem-aware and solution-seeking.
Include feature modifiers that describe what your product includes: "with [feature]" ("email marketing with automation"), "includes [component]" ("CRM includes mobile app"), "[feature] included" ("reporting included"), and "built-in [feature]" ("built-in time tracking"). People searching for specific features are often comparing solutions and close to a decision.
Add comparison and alternative modifiers: "[competitor] alternative," "better than [competitor]," "[product] vs [product]," "switch from [competitor]," and "replace [competitor]." These keywords capture people actively evaluating options. They're high-intent and often convert well, though they may face competition from the competitors you're naming.
Use price and value modifiers: "affordable," "cheap," "budget," "under $X," "best value," "cost-effective," and "pricing." Be careful with these—they attract price-sensitive customers—but they're valuable if you compete on price or if you want to capture budget-conscious segments of your market.
Include experience level modifiers: "for beginners," "easy," "simple," "advanced," "professional," and "enterprise." These help you target different customer segments. "Email marketing for beginners" attracts different buyers than "enterprise email marketing platform," and you can tailor your ad copy and landing pages accordingly.
Add time-based modifiers: "same day," "emergency," "24 hour," "fast," "quick," "immediate," and "urgent." These capture people with time-sensitive needs who are often willing to pay premium prices. "Emergency locksmith" commands higher rates than "locksmith," and the keyword reflects that urgency.
Create a modifier matrix. List your best-performing base keywords down the left column and your modifier categories across the top. Fill in the matrix with combinations that make sense. Not every combination will be valid—"emergency CRM software" doesn't make sense—but this systematic approach ensures you don't miss valuable variations.
Test plural and singular variations. "Running shoe" and "running shoes" might seem identical, but they can have different search volumes and competition levels. Google treats them as related but distinct keywords, so test both. The same applies to abbreviations and full terms: "CRM software" vs "customer relationship management software."
Step 6: Analyze Search Intent and Commercial Value
Not all long-tail keywords are created equal. Some drive conversions; others waste budget. Before you add keywords to your campaigns, you need to evaluate their commercial intent—the likelihood that someone searching this term is ready to take action.
Search intent falls into four categories: informational (learning about a topic), navigational (finding a specific site), commercial investigation (researching before buying), and transactional (ready to purchase or take action). For Google Ads, you want commercial investigation and transactional keywords. Informational keywords rarely convert and should usually be excluded.
Identify transactional intent through keyword structure. These words signal buying intent: "buy," "purchase," "order," "hire," "get," "download," "sign up," "free trial," "demo," "quote," and "pricing." A keyword like "buy running shoes online" is clearly transactional. "Running shoes benefits" is informational.
Commercial investigation keywords are trickier. They include terms like: "best," "top," "review," "comparison," "vs," "alternative," and "[year]" (as in "best CRM 2024"). These searchers aren't ready to buy this second, but they're actively evaluating options. They're in the consideration phase, and well-targeted ads can influence their decision.
Test keywords manually by searching them yourself. Look at what appears in the search results: if you see mostly ads and product pages, it's commercial intent; if you see mostly blog posts and how-to guides, it's informational intent; if you see a mix, it's commercial investigation. The search results page itself reveals how Google interprets the intent.
Check the suggested bid in Keyword Planner. High suggested bids indicate that other advertisers have found commercial value in this keyword. If a keyword has a $5 suggested bid, multiple advertisers are competing for it because it converts. If it has a $0.20 suggested bid, it's either low-value or low-competition—you need to determine which.
Look at the competition level in Keyword Planner. "Low" competition doesn't always mean low value—it might mean you've found an overlooked opportunity. But "High" competition definitely means other advertisers see value there. Cross-reference competition level with suggested bid to assess true opportunity.
Consider the customer journey stage. Someone searching "what is CRM" is at awareness stage—they're learning. Someone searching "CRM for small business" is at consideration stage—they're evaluating. Someone searching "HubSpot CRM pricing" is at decision stage—they're ready to buy. Focus your budget on consideration and decision stage keywords. Proper google ads conversion tracking helps you identify which journey stages actually convert for your business.
Evaluate keyword specificity as a proxy for intent. More specific usually means higher intent. "Software" is vague. "Project management software" is better. "Project management software for construction companies under 50 employees" is highly specific—and the person typing that knows exactly what they need.
Create an intent scoring system. Rate each keyword on a 1-10 scale for commercial intent, with 10 being "ready to buy now" and 1 being "just browsing." Only add keywords rated 6 or higher to your campaigns. This subjective scoring helps you prioritize when you have hundreds of potential keywords.
Step 7: Organize Keywords into Tightly Themed Ad Groups
You've researched hundreds of long-tail keywords. Now comes the crucial step: organization. How you structure your keywords into ad groups directly impacts your Quality Score, ad relevance, and ultimately your cost per click and conversion rate.
The fundamental principle: tight theme matching. Each ad group should contain keywords that are so similar you can write one ad that's highly relevant to all of them. If you need to write different ads for different keywords in the same ad group, your theme is too broad.
Start by grouping keywords by intent and specificity. Don't mix "running shoes" with "women's trail running shoes size 8 wide." They're related, but they require different ad copy and likely different landing pages. The first is broad; the second is specific. Create separate ad groups for different specificity levels.
Use the Single Keyword Ad Group (SKAG) strategy for your highest-value long-tail keywords. This means creating an ad group with just one keyword (in multiple match types). This allows you to write ad copy that exactly matches the search query, maximizing relevance and Quality Score. SKAGs work best for high-converting, specific long-tail terms.
For keywords that are similar but not identical, create small ad groups of 5-10 closely related keywords. For example, an ad group might contain: "CRM for real estate agents," "real estate CRM software," "CRM software for realtors," "realtor CRM system," and "real estate agent CRM." These are similar enough that one ad can address all of them.
Organize by modifier type. Create separate ad groups for: location-based keywords ("plumber in Chicago," "Chicago plumber," "plumber near me Chicago"), problem-based keywords ("fix leaky faucet," "repair running toilet," "unclog drain"), and feature-based keywords ("24 hour plumber," "emergency plumber," "same day plumber"). This organization allows you to tailor ad copy to the specific modifier.
Name your ad groups descriptively. Instead of "Ad Group 1," use "Real Estate CRM - Specific" or "Emergency Plumber - Chicago." Clear naming helps you navigate your account, understand performance at a glance, and maintain organization as your account grows. Six months from now, you'll thank yourself for descriptive names.
Create a campaign structure that reflects your business structure. If you offer multiple products or services, create separate campaigns for each. Within each campaign, create ad groups for different keyword themes. For example: Campaign: "CRM Software" → Ad Group: "Real Estate CRM," Ad Group: "Insurance CRM," Ad Group: "Small Business CRM."
Plan for ad copy variations. Each ad group should have 3-4 ad variations that you'll test against each other. As you organize keywords into ad groups, think about what ad copy would work for this group. If you can't imagine writing relevant ads, your grouping is too broad or too mixed.
Use a spreadsheet to map your structure before building it in Google Ads. Create columns for: Campaign, Ad Group, Keyword, Match Type, and Landing Page. This planning document becomes your blueprint for account setup and helps you spot organizational issues before you build them into your account. Understanding google ads keyword match types is essential for this planning phase.
Step 8: Implement Match Types Strategically
Match types determine when your ads show. Choose wrong, and you'll either miss valuable traffic or waste money on irrelevant searches. For long-tail keywords, match type strategy is especially important because you're trying to capture specific searches without overspending on variations.
Google Ads offers three match types: broad match (shows ads on related searches, including synonyms and variations), phrase match (shows ads on searches that include your keyword phrase in order), and exact match (shows ads on searches that match your keyword exactly or are close variations). Each serves a different purpose in long-tail strategy.
For highly specific long-tail keywords, start with phrase match. This gives you some flexibility while maintaining control. If your keyword is "women's trail running shoes for wide feet," phrase match will show your ad for "best women's trail running shoes for wide feet" and "buy women's trail running shoes for wide feet," but not for "women's running shoes" or "trail shoes."
Use exact match for your highest-converting long-tail keywords. Once you've identified a specific phrase that converts well, create an exact match version to ensure you're always showing for that precise search. Exact match gives you maximum control and typically the highest conversion rates, though at lower volume.
Be cautious with broad match on long-tail keywords. Broad match can expand your reach, but it can also trigger your ads on loosely related searches that waste budget. If you use broad match, do it only with strong negative keyword lists and close monitoring. For most long-tail strategies, phrase and exact match are safer starting points.
Implement a match type hierarchy. Create the same keyword in multiple match types within the same ad group: exact match at your target CPC, phrase match at 80% of your target CPC, and broad match (if used) at 60% of your target CPC. This ensures exact matches get priority, and you only pay more for less precise matches if they're performing well.
Use broad match modifier strategically. By adding a plus sign before keywords (+women's +trail +running +shoes), you ensure all those terms must appear in the search, but in any order. This is broader than phrase match but more controlled than broad match. It's useful for capturing variations while maintaining relevance.
Monitor search terms reports religiously. Go to Keywords > Search Terms in Google Ads to see the actual searches that triggered your ads. This report reveals whether your match types are working. If you see irrelevant searches, tighten your match types or add negative keywords. If you see valuable searches you're missing, expand your match types.
Adjust match types based on performance. Start conservative with phrase and exact match. After 2-4 weeks, review performance. If a keyword is converting well and you want more volume, add a broader match type. If it's triggering irrelevant searches, tighten to exact match or add negatives. Match type strategy should evolve with data.
Consider match types in your budget allocation. Exact match keywords typically have lower volume but higher conversion rates. Phrase match has moderate volume and conversion rates. Broad match has highest volume but lowest conversion rates. Allocate budget accordingly—more to exact and phrase, less to broad until it proves itself.
Step 9: Build and Refine Your Negative Keyword List
Negative keywords are as important as your target keywords. They prevent your ads from showing on irrelevant searches, saving budget and improving campaign performance. For long-tail keyword strategies, negative keywords help you stay focused on high-intent searches.
Start with obvious negatives. These are terms that clearly indicate no buying intent: "free," "cheap," "DIY," "how to," "tutorial," "course," "jobs," "salary," "career," "resume," and "wikipedia." If you're selling software, you don't want to show ads to people searching for jobs at software companies or free alternatives.
Add competitor names as negatives if you're not targeting them. If someone searches "HubSpot CRM pricing" and you're not HubSpot, they're looking for a specific competitor, not alternatives. Unless you're running competitor campaigns, add competitor names as negatives to avoid wasting clicks.
Use your search terms report to find negative keywords. This is your most valuable source. Review it weekly and look for searches that triggered your ads but aren't relevant. If you sell B2B software and you see searches for "student discount" or "for personal use," add those as negatives.
Create negative keyword lists at the campaign level. Google Ads allows you to create lists of negative keywords that you can apply to multiple campaigns. Build lists like: "General Negatives" (free, cheap, DIY, etc.), "Job Seekers" (jobs, career, salary, resume, etc.), "Competitors" (competitor names and products), and "Wrong Audience" (terms specific to audiences you don't serve).
Be strategic with informational terms. Words like "what is," "how to," and "guide" often indicate informational intent, but not always. "What is the best CRM for real estate" is informational in structure but commercial in intent. Review these case-by-case rather than blanket-blocking all informational terms. Maintaining a comprehensive find negative keywords process helps you continuously refine your exclusions.
Add negative keywords for features you don't offer. If you don't have a mobile app, add "mobile app" as a negative. If you don't offer 24/7 support, add "24/7" and "24 hour" as negatives. This prevents disappointing clicks from people looking for features you can't provide.
Use negative keyword match types strategically. Negative exact match excludes only that specific term. Negative phrase match excludes searches containing that phrase. Negative broad match excludes searches containing any of those words in any order. For most negatives, phrase match provides good coverage without being overly restrictive.
Review and update negatives monthly. As your campaigns run, you'll discover new irrelevant searches. Make negative keyword review a regular part of your optimization routine. Set a calendar reminder to review search terms and add negatives every 2-4 weeks, more frequently when campaigns are new.
Don't over-negative. It's possible to be too aggressive with negative keywords and block valuable traffic. If you add "cheap" as a negative, you might also block "cheap compared to competitors" or "not cheap but worth it." Review your negative keyword list periodically to ensure you're not being overly
