How to Do Google Ads Keyword Research: A Step-by-Step Guide for PPC Success

Google Ads keyword research is the foundation of every profitable PPC campaign. Get it wrong, and you're basically throwing money at people who'll never buy from you. Get it right, and you're showing up exactly when potential customers are searching for what you offer.

This guide walks you through the complete process—from understanding search intent to building keyword lists that actually convert. Whether you're managing your own campaigns or handling multiple client accounts, these steps will help you find high-intent keywords, avoid wasted spend on junk terms, and structure your campaigns for maximum ROI.

No fluff, no theory-heavy nonsense—just the practical workflow that experienced PPC managers actually use.

Step 1: Define Your Campaign Goals and Audience Intent

Before you dive into any keyword tool, you need crystal clarity on what you're trying to accomplish. Are you driving immediate sales? Building awareness for a new product? Capturing leads for a high-ticket service?

Your campaign goal directly determines which keywords make sense. If you're selling a $20 product with thin margins, you can't afford to bid on vague awareness-stage keywords that cost $5 per click. But if you're selling enterprise software with a $50,000 average contract value, suddenly those pricier, broader terms become viable.

Think about where your audience sits in their buying journey. Someone searching "what is project management software" is just starting their research. Someone searching "asana vs monday pricing comparison" is much closer to pulling out their credit card. These represent completely different intent levels, and they require different keyword strategies.

Map your products or services to the actual problems people are searching to solve. You might sell "cloud-based inventory management systems," but your customers are searching for "how to track stock levels automatically" or "prevent stockouts small business." The language disconnect between what you call your product and what customers actually type into Google is where most keyword research goes wrong.

Create quick audience personas that inform your keyword language choices. A CFO searching for accounting software uses different terminology than a small business owner doing their own books. Industry jargon that makes perfect sense to you might be completely foreign to your target customer—or vice versa.

Your budget constraints matter enormously here. If you've got $500 per month to spend, you need to be ruthlessly focused on high-intent, lower-competition keywords. Trying to compete for broad, expensive terms will drain your budget in days with nothing to show for it. Know your limits before you start building lists.

Step 2: Build Your Seed Keyword List

Your seed keyword list is the foundation everything else builds from. Start with the obvious stuff—your core products, services, and the straightforward terms customers use to describe what you sell.

But here's where most people stop way too early. The real gold comes from mining the language your actual customers use. Pull up your website analytics and look at what organic search terms are already bringing people to your site. Check your customer support tickets for the exact phrases people use when describing their problems. Listen to sales call recordings and note the terminology prospects use before you "educate" them on your preferred industry language.

These real-world data sources reveal how people actually talk about your products, not how you think they should talk about them. That subtle difference can make or break your keyword strategy.

Now fire up Google Keyword Planner—it's free inside your Google Ads account. Enter your seed keywords and let the tool expand them with related terms and search volume data. Pay attention to the suggestions that surprise you. Those unexpected keyword variations often reveal search patterns you never would have thought of on your own.

Take a look at your competitors' ads. Search for your main keywords and study what your competitors are bidding on. What language are they using in their ad copy? What landing pages are they sending traffic to? This competitive intel shows you what's working in your market right now.

Don't just copy your competitors blindly—they might be making expensive mistakes—but their keyword choices give you valuable clues about what terms actually drive results in your industry.

Use Google's autocomplete feature strategically. Start typing your seed keywords into the search bar and watch what Google suggests. These autocomplete suggestions are based on real search volume, showing you the exact phrases people are typing most often.

Check the "People also ask" and "Related searches" sections on Google search results pages. These features reveal the questions and adjacent topics people are exploring around your core keywords. Each one is a potential keyword opportunity.

At this stage, cast a wide net. You'll narrow down later. Right now, you want quantity—aim for 50-100+ seed keywords that you can refine in the next steps.

Step 3: Analyze Search Intent and Keyword Types

Not all keywords are created equal, and understanding search intent is what separates profitable campaigns from budget-draining disasters. Every keyword falls into one of four intent categories, and each requires a completely different approach.

Informational keywords are when people are learning and researching. Searches like "what is email marketing" or "how does PPC work" signal someone at the very beginning of their journey. These keywords typically have high search volume and low cost, but they rarely convert immediately. They're useful for building awareness and capturing early-stage leads, but they won't drive direct sales.

Navigational keywords are when someone's looking for a specific brand or website. Searches like "mailchimp login" or "hubspot pricing" show clear destination intent. Unless they're searching for your brand specifically, these keywords usually aren't worth bidding on—you're just paying to send people to your competitors.

Commercial keywords indicate someone's actively comparing options. Terms like "best crm software," "shopify vs woocommerce," or "top email marketing tools" signal they're in decision mode. These keywords have moderate competition and cost, but they convert much better than informational searches because the person is actively evaluating solutions.

Transactional keywords are the gold standard. Searches like "buy standing desk," "hire seo consultant," or "schedule pest control service" show someone ready to take action right now. These keywords typically cost more because everyone wants them, but they deliver the highest conversion rates and ROI.

Now let's talk match types, because they dramatically affect when your ads actually appear. Google's match type system has evolved significantly, and understanding how keyword match type affects your Google Ads performance is critical.

Exact match used to mean exactly what it sounds like—your ad only showed for that precise keyword. Now it includes close variants like singular/plural forms, misspellings, and same-intent phrases. So if you bid on [email marketing software], you might show for "email marketing platform" or "e-mail marketing software."

Phrase match gives you more flexibility while maintaining some control. Your keyword needs to appear in the search query with the same meaning, but other words can come before or after. It's useful for capturing variations while avoiding completely irrelevant searches.

Broad match is the wild west. Google uses machine learning to show your ads for searches it thinks are related to your keyword, even if the actual words don't match. This can uncover surprising opportunities, but it can also waste budget fast if you're not aggressive with negative keywords.

For most campaigns, start with phrase and exact match for your high-intent keywords. Use broad match sparingly and only when you're committed to monitoring search terms closely and adding negatives constantly. Learn more about Google Ads keyword match types to make informed decisions.

Step 4: Evaluate Competition and Cost Metrics

Having a great keyword list doesn't mean much if you can't afford to compete for those terms or if the economics don't work out. This step is where strategy meets reality.

Back in Google Keyword Planner, look at the competition level for each keyword—marked as low, medium, or high. This tells you how many other advertisers are bidding on that term. High competition means you're fighting for ad space against lots of other businesses, which typically drives up costs.

The suggested bid range shows what advertisers are typically paying per click for that keyword. These numbers are estimates, but they give you a realistic starting point for budget planning. If a keyword shows a suggested bid of $25 and your average order value is $30, the math probably doesn't work unless you have exceptional conversion rates.

Here's where you need to do some honest ROI math. Take your average conversion rate—let's say 2% of clicks turn into customers. If you're paying $5 per click, that means you need 50 clicks to get one customer, costing you $250 in ad spend. Does your average customer value justify that acquisition cost? If not, you need cheaper keywords or a better conversion rate.

This is where long-tail keywords become your secret weapon. These three-plus-word phrases typically have lower search volume but also lower competition and cost. Someone searching "affordable standing desk for home office under 500" is way more specific—and often closer to buying—than someone just searching "desk." Learn how to research long tail keywords for Google Ads to unlock these opportunities.

Long-tail keywords let you compete in markets where the broad terms are dominated by companies with massive budgets. You can't outbid Amazon on "office furniture," but you can absolutely compete on "ergonomic desk for programmers with back pain."

Look for the sweet spot—keywords with decent search volume, manageable competition, and cost-per-click rates that work within your budget constraints. If you're struggling with high CPCs, explore strategies on what you can do to lower your Google Ads cost per click.

Don't ignore search volume completely, but don't worship it either. A keyword with 10 monthly searches that converts at 10% is infinitely more valuable than a keyword with 1,000 monthly searches that converts at 0.1%. Quality beats quantity every time in PPC.

Step 5: Organize Keywords into Themed Ad Groups

Random keyword lists don't win at Google Ads. Tight, strategically organized ad groups do. This step is where you transform your keyword research into an actual campaign structure that drives results.

The principle is simple: group keywords together that are similar enough to share the same ad copy and landing page. When your keywords, ads, and landing pages are tightly aligned, Google rewards you with higher Quality Scores, which means lower costs and better ad positions.

Let's say you sell project management software. You might create separate ad groups for "project management software," "task management tools," "team collaboration software," and "project tracking apps." Even though these are related, each deserves its own ad group because the search intent and ideal ad messaging are slightly different.

Aim for 5-15 keywords per ad group. Go tighter rather than looser. If you're cramming 50 keywords into one ad group, your ad copy will be too generic to resonate with any of those searches specifically. You'll get lower click-through rates and worse Quality Scores.

Think about your campaign structure logically. You might organize by product line—one campaign for each major product category. Or by funnel stage—separate campaigns for awareness, consideration, and purchase-intent keywords. Or by audience segment—different campaigns for small businesses versus enterprise customers.

There's no one perfect structure, but the best structures make it easy to control budgets, write relevant ads, and analyze performance. If you can't quickly understand what a campaign or ad group is targeting just by reading its name, your structure needs work. For a complete walkthrough, see our guide on how to create a search campaign in Google Ads.

Create ad groups that enable you to write hyper-specific ad copy. If someone searches "email marketing software for e-commerce," your ad should mention e-commerce specifically. That level of relevance is only possible when your ad groups are tightly themed.

Your landing pages need to match too. Each ad group should send traffic to a landing page that directly addresses those specific keywords. Sending everyone to your generic homepage is a conversion killer. The more aligned your keyword → ad → landing page journey, the better your results.

Step 6: Build Your Negative Keyword List from Day One

Here's the truth most beginners miss: negative keywords are just as important as the keywords you're targeting. Maybe more important. They're what prevent you from wasting money on searches that will never convert.

Negative keywords tell Google which searches should NOT trigger your ads. If you sell premium software, you don't want your ads showing for "free project management tools" or "open source alternatives." Those clicks cost you money and deliver zero value.

Start building your negative keyword list before you even launch. Think about all the ways people might search for things adjacent to what you offer but completely wrong for your business. Understanding what negative keywords are in Google Ads is essential for protecting your budget.

Common negative keywords for most B2B service businesses include: free, cheap, jobs, career, salary, course, tutorial, DIY, how to, template, and download. These terms signal someone looking for free resources or employment, not someone ready to buy your product or service.

Industry-specific negatives matter too. If you're a pest control company, you probably want to add "pictures," "identification," and "types of" as negatives—those searches are informational, not transactional. Someone searching "types of termites" isn't looking to hire an exterminator right now.

Create negative keyword lists at three levels. Account-level negatives apply to every campaign—these are universal junk terms you never want to show for. Campaign-level negatives apply to specific campaigns where certain terms don't make sense. Ad group-level negatives fine-tune even further. Learn how to find negative keywords in Google Ads effectively.

Don't just think about completely irrelevant terms. Also consider terms that might be relevant but target the wrong customer. If you only serve businesses, add B2C-focused terms as negatives. If you're local-only, add other geographic locations. If you sell new products, add "used," "refurbished," and "second hand."

The biggest mistake is thinking you can set negatives once and forget them. Your negative keyword list needs constant maintenance as you discover new junk terms triggering your ads. Which brings us to the final step.

Step 7: Validate and Refine Using Search Terms Reports

This is where keyword research transforms from a one-time project into an ongoing optimization process. The Google Ads Search Terms Report shows you the actual queries that triggered your ads—and this data is absolute gold.

Once your campaigns are live, check your Search Terms Report at least weekly. You'll discover things you never would have predicted. Some keywords you thought would be winners perform terribly. Other search queries you never considered are converting like crazy.

The optimization workflow is straightforward but powerful. Look for high-performing search terms—queries that are driving clicks, conversions, and sales at good costs. Add these as new keywords in your campaigns so you can bid on them more aggressively and write specific ad copy for them.

Then ruthlessly eliminate the junk. You'll see search queries that are technically related to your keywords but completely irrelevant to your business. Add these as negative keywords immediately to stop wasting money on them. Master Google Ads search terms analysis to identify these opportunities faster.

This is tedious work if you're doing it manually—downloading reports, sorting through data, copying and pasting keywords and negatives back and forth. Many advertisers skip this optimization because it's time-consuming and boring. That's a massive mistake that costs them thousands in wasted spend.

Tools that streamline this process directly within Google Ads make the optimization workflow dramatically faster. When you can review search terms, add negatives, create new keyword groups, and apply match types without leaving the interface or touching a spreadsheet, you're more likely to actually do the optimization consistently.

Pay attention to patterns in your search terms data. If you're seeing lots of mobile-related searches, maybe you need a mobile-specific campaign. If certain geographic locations convert better, adjust your targeting. If specific product variations get more interest, create dedicated ad groups for them.

The Search Terms Report also reveals match type issues. If your exact match keywords are triggering surprisingly broad searches, you might need to tighten things up with more negatives or different match types.

Putting It All Together

Before you launch your next Google Ads campaign, run through this quick checklist. Have you defined clear campaign goals that match your business objectives? Did you build a seed list from real customer language, not just what you think people search for? Have you categorized your keywords by intent so you're targeting the right stage of the buyer journey?

Make sure you've evaluated competition and costs within your actual budget constraints. Organize your keywords into tight ad groups that enable specific, relevant ad copy. And critically, create that starter negative keyword list before you spend a single dollar.

Here's the thing: Google Ads keyword research isn't a one-time task you complete and move on from. The real magic happens when you continuously refine based on actual search term data. The campaigns that print money are the ones where someone is regularly reviewing the Search Terms Report, adding winners as new keywords, and ruthlessly eliminating the junk.

Review your Search Terms Report weekly at minimum. Daily is better if you're spending significant budget. Every day you let junk search terms drain your budget is money you're literally throwing away.

That ongoing optimization is what separates profitable campaigns from money pits. You can have perfect keyword research on day one, but if you're not optimizing based on real performance data, you're leaving massive amounts of money on the table.

The advertisers who win at Google Ads aren't necessarily the ones with the biggest budgets or the fanciest strategies. They're the ones who consistently do the unglamorous work of keyword optimization week after week. They add negatives. They find new keyword opportunities. They adjust bids based on performance. They never stop refining.
