What Are the Steps to Perform Keyword Research for Google Ads? A Practical Guide

TL;DR: Keyword research for Google Ads isn't just about finding search terms. It's about finding the right ones that match buyer intent, fit your budget, and actually convert. This guide walks you through seven repeatable steps: defining your goals, building a seed list, validating volume, assigning match types, building your negative keyword list, organizing ad groups, and maintaining your search terms report over time.

Most Google Ads keyword research advice falls into one of two traps. It's either too vague ("just use Keyword Planner!") or too broad to be actionable. Here's the thing most guides miss: keyword research for paid search is fundamentally different from SEO keyword research. You're not chasing traffic volume. You're chasing intent. Every keyword you add costs real money when someone clicks, so precision matters far more than reach.

In most accounts I audit, the biggest waste isn't coming from bad bidding strategies or poor ad copy. It's coming from a sloppy keyword list built without a clear process. Too many broad terms, no negative keywords, mismatched ad groups, and zero ongoing maintenance of the search terms report.

This guide is written for marketers, freelancers, and agency owners who want a structured, repeatable workflow. We'll cover the full process from scratch, including how to handle match types, build negative keyword lists, and keep your search terms report clean over time. Estimated reading time: 8 minutes.

Step 1: Define Your Campaign Goals and Audience Before Touching Any Tool

This is the step most people skip because it feels like admin work. It isn't. Skipping it is exactly why so many campaigns generate clicks without conversions.

Start with your conversion goal. What specific action do you want users to take when they land on your page? A purchase, a form fill, a phone call, a demo signup? The answer shapes everything downstream, including which keywords are worth targeting and which ones just look good on paper.

Next, get clear on your audience. Who are they, what problem are they trying to solve, and what language do they use to describe that problem? A B2B buyer searching for "enterprise project management software" is in a completely different headspace than someone searching "free task list app." Both might be relevant to your product, but they require different keywords, different ad copy, and probably different landing pages.

Also define your geography, device preferences, and budget range before you start researching keywords. These constraints directly affect which keywords are viable. If your average CPC target is $2 and a keyword's top-of-page bid is $15, it doesn't matter how relevant it is. You need to know your limits before you fall in love with a keyword.

Finally, map out your offer clearly. What are you selling, what makes it different, and what objections do buyers typically have at the point of searching? This gives you the foundation for writing ad copy that actually resonates, and it helps you filter out keywords where the searcher's intent doesn't match what you're offering.

Common pitfall: Jumping straight into Keyword Planner without this groundwork leads to lists full of plausible-looking terms that never convert. The keywords feel right, but they attract the wrong people.

Success indicator: You can write a one-paragraph brief describing your ideal searcher, what they're looking for, and what they expect to find when they click your ad. If you can do that, you're ready for Step 2.

Step 2: Build Your Seed Keyword List from First Principles

Before you open any tool, build your seed list manually. This forces you to think like your customer rather than letting an algorithm do your thinking for you.

Pull from three sources to start. First, your own knowledge of the business: the product or service name, core category terms, and the problem-based phrases your audience actually uses. Second, competitor ad copy. Run a few searches on Google and look at what ads are showing up. The language competitors use in their headlines and descriptions often reveals keyword themes you haven't thought of. Third, if the account has history, pull your existing search terms report. Real user queries are always more valuable than tool-generated suggestions.

Group your seed keywords by intent. For Google Ads specifically, this matters more than most guides acknowledge:

Informational intent: "What is project management software," "how to manage a remote team." These rarely convert in paid search and typically waste budget. Avoid them unless you're running a top-of-funnel awareness campaign with a very specific strategy.

Commercial intent: "Best project management tool for small teams," "Asana vs Monday," "project management software comparison." These indicate someone who's researching and close to a decision. High value.

Transactional intent: "Project management software pricing," "buy project management tool," "project management software free trial." These are your highest-priority keywords. The searcher is ready to act.

For a practical example: if you sell project management software, your seed list might include "project management tool," "task tracking software," "team collaboration app," "Asana alternative," "project management software pricing," and "best tool for managing remote teams." That's a starting point, not a final list.

Aim for 20 to 40 seed terms across intent categories before you move to expansion tools. Also create a separate seed group for branded competitor terms. You'll evaluate those separately since they carry different bid dynamics and legal considerations depending on your market.

Success indicator: Your seed list is organized by intent, covers your core offer from multiple angles, and doesn't include any terms you'd be embarrassed to explain to a client.

Step 3: Expand and Validate Keywords Using Google's Keyword Planner

Now you can open a tool. Google Keyword Planner is free inside Google Ads, and for most advertisers it's the right starting point for validation. Use the "Discover new keywords" function and paste in your seed list.

What you're looking for in the output: average monthly searches, competition level (low, medium, or high), and top-of-page bid ranges. Use these three data points together, not in isolation. A keyword with high volume and high competition might be too expensive for your budget. A keyword with lower volume but low competition and a bid you can afford might be a better starting point.

Filter aggressively. Remove keywords with no commercial intent. Remove overly broad terms that could match irrelevant queries at scale. Remove anything where the bid range blows past your CPC target. The goal isn't a big list. It's a clean, viable list.

Use the Forecasts tab to estimate impressions, clicks, and cost at your planned budget. This step prevents surprises after launch. If the forecast shows you'll burn through your monthly budget in four days at those bids, you need to either narrow your keyword list or adjust your expectations before you go live.

Cross-reference your Keyword Planner output with Google's autocomplete and the "People also search for" section in the SERP. These surface real user language that tools sometimes miss, especially for long-tail variations.

Long-tail keywords, typically three to five words, tend to have lower CPCs and higher purchase intent. They're especially valuable for new campaigns with limited budgets where you need every dollar to work harder. "Project management software for construction teams" converts better and costs less than "project management software" in most accounts I've managed.

Success indicator: You have a validated list of 50 to 150 keywords organized by theme, with rough CPC estimates for each group. You know which themes are affordable and which ones will need tighter budget controls.

Step 4: Assign Match Types Strategically, Not Randomly

Match type assignment is where most advertisers either lose control of their spend or leave performance on the table. It's not an afterthought. It's a core part of your keyword strategy.

Here's a quick breakdown of how the three match types actually work in practice:

Broad Match: Google decides which queries your keyword is relevant to. The reach is wide, sometimes very wide. Without Smart Bidding and a solid negative keyword list, Broad Match burns budget fast. It can work well for accounts with strong conversion data and automated bidding, but it's a bad default for new campaigns.

Phrase Match: Your ad shows when the query contains the meaning of your keyword. It gives you more control than Broad Match while still capturing variations you might not have thought of. This is the recommended default for most new campaigns.

Exact Match: Your ad shows when the query closely matches your keyword's meaning. Use this for your highest-confidence, highest-converting terms where you know exactly what the searcher wants and you want full control over when your ad appears.

The recommended starting strategy for new campaigns: default to Phrase Match across most of your list, then layer in Exact Match for your top-priority terms where you have high confidence in intent. Reserve Broad Match for controlled testing once you have conversion data and Smart Bidding in place.

The mistake most agencies make is applying one match type uniformly across an entire campaign without thinking about which keywords warrant tighter control. A branded competitor keyword and a generic category term should not have the same match type.

Practical tip: group keywords by match type within your ad groups. This lets you track performance separately, adjust bids at the match type level, and identify quickly which match type is driving the most efficient conversions. It also makes reporting cleaner for clients.

Success indicator: Every keyword in your list has a match type assigned with a reason behind it, not just a default setting applied in bulk.

Step 5: Build Your Negative Keyword List Before You Go Live

Negative keywords are where wasted spend gets stopped before it starts. Building this list before launch is non-negotiable.

Start with the obvious negatives that apply to almost any campaign: "free," "DIY," "how to," "what is," "jobs," "careers," "salary," "course," "tutorial," and any competitor names you're not intentionally targeting. These terms signal searchers who aren't going to buy from you.

Then go deeper. Use Keyword Planner to check what queries your Phrase Match and Broad Match keywords might trigger. If you're targeting "project management software," you might also be triggering searches for "project management software open source free" or "project management software for students." Add anything irrelevant to your negative list now, before those clicks happen.

Organize negatives at the right level. Campaign-level negatives apply across all ad groups in that campaign, which is efficient for universal exclusions. Ad group-level negatives give you more surgical control when you need to prevent one ad group from stealing traffic that should go to another.

Use Exact Match negatives for specific irrelevant queries you know you'll encounter. Use Phrase Match negatives for broader categories of bad traffic you want to exclude across many variations.

If the account has any history, pull the historical search terms report and filter for zero-conversion queries with spend. That's your negative list starter pack, and it's more accurate than anything you'll build from guesswork.

Success indicator: Your negative keyword list has at least 20 to 30 terms before the campaign launches. If you're launching with fewer than that, you haven't looked hard enough.

Step 6: Organize Keywords into Tightly Themed Ad Groups

Ad group structure directly affects Quality Score, ad relevance, and your CPC. This step gets skipped or done sloppily more often than any other, and it costs advertisers real money.

The rule of thumb: one tight theme per ad group, with 5 to 20 closely related keywords that all justify the same ad copy and point to the same landing page. If two keywords would require meaningfully different ad copy to be relevant, they belong in different ad groups.

Don't mix "project management software" and "task tracking app" in the same ad group if your ad copy and landing page can't speak to both equally well. Split them. Your Quality Scores will thank you.

On the question of SKAGs (Single Keyword Ad Groups): they were popular a few years ago because they gave maximum control over ad relevance. With current match type behavior, especially how Phrase Match and Exact Match have evolved, SKAGs are largely obsolete. Tightly themed groups with 5 to 15 related keywords work better now and are much easier to manage at scale.

Name your ad groups clearly. Use names that describe the theme without requiring someone to open the ad group to understand it. "Phrase - Project Management Software - Pricing" is more useful than "Ad Group 3" when you're managing a large account or handing it off to a colleague.

Each ad group should map to a specific landing page that matches the keyword theme. This is one of the most common conversion killers I see in account audits: the keyword is relevant, the ad is decent, but the landing page is a generic homepage that doesn't speak to what the searcher wanted. Mismatched landing pages destroy conversion rates and drag down Quality Scores.

Success indicator: Every ad group has a clear theme, a matching landing page, and ad copy that speaks directly to what someone searching those keywords is looking for.

Step 7: Monitor the Search Terms Report and Refine Continuously

This is where real PPC performance is won or lost, and it's the step most guides either skip entirely or treat as an afterthought. Keyword research doesn't end at launch. It's an ongoing process driven by real search data.

Check your Search Terms Report at least weekly for new campaigns, and bi-weekly for established ones. The Search Terms Report is not the same as your Keywords tab. It shows the actual queries that triggered your ads, which is often very different from the keywords you're bidding on.

In the report, you're looking for three things. First, irrelevant queries to add as negatives. Second, high-performing queries to add as Exact Match keywords so you can control their bids and track them directly. Third, patterns in what's actually triggering your ads, because those patterns often reveal keyword themes you haven't built out yet.

What usually happens here is that you'll find a mix of surprisingly good queries and surprisingly bad ones. The good ones are often long-tail variations you didn't think to include in your original list. Add them as Exact Match keywords immediately so you can bid on them intentionally rather than accidentally.

The search terms report is also your best ongoing source of keyword ideas. Real user language beats any keyword tool because it shows you exactly how your target audience phrases their searches, not how Google thinks they might.

Tools like Keywordme make this process significantly faster. Instead of exporting your search terms to a spreadsheet, sorting through them manually, and then uploading changes back into Google Ads, you can take action directly inside the interface. One click to add a term as a keyword, apply a match type, or push it to your negative list. For agencies managing multiple accounts, that time savings adds up quickly.

Success indicator: Your irrelevant search term rate decreases over time, your average CPC trends downward as Quality Scores improve, and your negative keyword list grows steadily based on real data rather than guesswork.

Your Keyword Research Checklist: All 7 Steps at a Glance

Here's the full process in quick-reference format. Use this every time you build or audit a Google Ads campaign.

1. Define goals and audience: Conversion goal, target audience, geography, device, budget range, and offer clarity.

2. Build your seed list: Product terms, category terms, problem-based phrases, competitor ad copy, and existing search terms. Grouped by intent: informational, commercial, transactional.

3. Expand and validate: Use Google Keyword Planner to expand seeds, filter by CPC viability, and use Forecasts to stress-test your budget. Aim for 50 to 150 validated keywords grouped by theme.

4. Assign match types: Phrase Match as default, Exact Match for high-confidence terms, Broad Match only with Smart Bidding and strong negatives in place.

5. Build your negative keyword list: At least 20 to 30 negatives before launch. Use Keyword Planner to anticipate bad traffic, and pull historical data if available.

6. Organize ad groups: Tight themes, 5 to 20 keywords per group, matching landing pages, clear naming conventions.

7. Monitor and refine: Weekly search terms review for new campaigns. Add negatives, promote high-performers to Exact Match, and expand into new themes as the data reveals them.

The biggest gains in most accounts don't come from the initial build. They come from the ongoing work in Steps 5 through 7. The foundation matters, but the refinement is where performance compounds over time.
