Most Google Ads accounts don’t fail because of bad bidding strategies or weak ad copy. They fail because someone picked the wrong keywords, threw a budget at them, and called it a campaign.
We’ve audited hundreds of accounts over the years. The single most common problem isn’t a technical setting — it’s a keyword list full of terms that attract browsers, researchers, students, and competitors instead of buyers. Fix the keyword foundation, and everything else gets easier. Leave it broken, and no amount of smart bidding will save you.
This is the full framework for how to do keyword research for Google Ads — not the tool walkthrough Google wants you to follow, but the strategic approach that actually produces campaigns worth running.
- Keyword research for Google Ads is fundamentally about buyer intent — not search volume. High-volume keywords are often the most expensive and least qualified.
- Google’s Keyword Planner is a starting point, not the whole answer. Layer it with search terms data, competitor research, and customer language.
- Match type selection is inseparable from keyword strategy — the same keyword behaves completely differently as exact, phrase, or broad match.
- Your negative keyword list is half your keyword strategy. Building it proactively is what separates efficient accounts from money pits.
- Keyword research is never finished. The best accounts treat it as a weekly process fed by live search terms data, not a one-time setup task.
Start With Intent, Not Volume — Here’s Why That Order Matters
The default instinct when opening Keyword Planner is to type in your product or service and sort by monthly searches. That instinct will cost you money.
High search volume often signals a mixed-intent audience. Take “project management software” — 50,000+ monthly searches, $15–$30 CPCs in many markets, and a searcher pool that includes students doing homework, employees researching on behalf of a boss who’ll never approve it, and tire-kickers who’ve been “evaluating options” for two years. The searcher who types “project management software for construction teams pricing” is rarer, but they’re three times more likely to convert and will cost you a fraction of the chaos you’d get from the head term.
The framework: sort every keyword candidate into three buckets before you ever check volume.
- Bottom-funnel / transactional: The searcher is ready to buy or evaluate seriously. Includes terms like “buy,” “pricing,” “cost,” “get a quote,” “[product] for [specific use case],” “[service] near me.” These are your primary targets.
- Mid-funnel / comparison: The searcher is comparing options. “[Product A] vs [Product B],” “best [category] for [use case],” “top [service providers] in [city].” Worth targeting if your economics support it — understand that conversion rates will be lower.
- Top-funnel / informational: “What is X,” “how does X work,” “X explained.” Almost never worth bidding on unless you’re doing brand awareness with display — and even then, it’s hard to justify the spend against real bottom-funnel competition.
Map your keyword ideas to these buckets first. Then check volume. You’ll immediately cut your list in half and dramatically improve your signal-to-noise ratio. This is the core of building a campaign structure built around customer intent — not just keyword categories.
How to Actually Use Google Keyword Planner (Without Getting Played by It)
Keyword Planner is genuinely useful. It’s also designed to make you buy more keywords than you need. Here’s how to use it without falling into the trap.
The right starting point: seed keywords from real customer language
Don’t start Keyword Planner with your internal product terminology. Start with the words your customers use when they have the problem you solve. Talk to your sales team. Pull language from sales call transcripts. Read your one-star competitor reviews on G2 or Capterra — that’s pure, unfiltered buyer vocabulary. The gap between how companies describe their product and how buyers search for it is often enormous.
Run three to five of those seed terms through Keyword Planner’s “Discover new keywords” feature. Export everything. Don’t filter yet — you want the full messy universe before you start cutting.
Read the competition column honestly
Keyword Planner’s “Competition” column (Low / Medium / High) reflects advertiser competition, not SEO difficulty. High competition means lots of advertisers are bidding — which typically means those keywords convert well for someone. It also means CPCs will be elevated. Low competition on a relevant term is a potential arbitrage opportunity worth investigating.
The suggested bid ranges are directionally useful but routinely wrong for specific accounts. They’re averages across all advertisers, all Quality Scores, all landing pages. Your actual CPC will depend heavily on your Quality Score, landing page relevance, and how much your competitors are willing to pay. If you want a realistic sense of what clicks will actually cost your specific business, read our breakdown of realistic Google Ads cost expectations by industry.
Use “Start with a website” for competitor intelligence
One underused Keyword Planner feature: enter a competitor’s URL instead of seed keywords. Google will pull keywords it associates with that site. This isn’t perfect, but it surfaces terms you might never have thought of — especially for competitors who’ve clearly invested in their keyword strategy. Run three to four competitors through this and merge the lists.
Match Types Are Strategy, Not Settings — Get This Wrong and Your Research Means Nothing
You can do perfect keyword research and completely wreck it by applying the wrong match types. Match types determine what searches your ads actually show up for. They turn a targeted keyword into a broad net — or lock it down to exact phrases only.
Exact match ([keyword]) only triggers your ad for that specific query or very close variants. It gives you the most control and the clearest data. Start here for your highest-intent, highest-value keywords.
Phrase match (“keyword”) triggers for queries that include the meaning of your keyword. It’s expanded significantly over the past few years — it now catches more variants than it used to. Still useful for capturing natural language variations without going fully open-ended.
Broad match (keyword) will trigger for anything Google’s algorithm thinks is related. This can be useful — we’ve seen broad match surface converting search terms that exact and phrase missed entirely. But it only works if you have a strong negative keyword list, meaningful conversion data for the algorithm to optimize against, and the discipline to review your search terms report weekly. Without those three things, broad match is a budget leak. If you want the full picture on when broad match is actually worth running, we’ve covered exactly when to use broad match in Google Ads — including the controls you need to have in place first.
For most accounts starting fresh: lead with exact match on your clearest buyer-intent terms. Add phrase match for natural language variations. Add broad match only after you have 30+ conversions in the account and a tight negative keyword list.
Build Your Negative Keyword List Before You Launch — Not After
Most advertisers treat negative keywords as a reactive task: something you clean up after you’ve wasted money on bad traffic. That’s the wrong mental model.
Your negative keyword list is half your keyword strategy. Building it proactively — before a single dollar is spent — is one of the highest-ROI things you can do in setup.
Here’s how to build a proactive negative list:
- Run your seed keywords through Keyword Planner and look at what comes back. You’ll immediately see informational terms, unrelated industries, and DIY searchers you want to exclude.
- Think through the universe of people who might trigger your keywords but would never buy. Students. Employees at companies too small for your minimum contract. Searchers in geographies you don’t serve. Competitors researching you. Build negatives for each.
- Add universal negatives from day one: “free,” “DIY,” “how to,” “what is,” “definition,” “salary,” “jobs,” “resume,” “course,” “tutorial,” “certification.” Adjust based on your specific context — a coding bootcamp obviously shouldn’t negative out “course.”
- Think about industry-adjacent terms that share vocabulary with your keywords. A cybersecurity company bidding on “network monitoring” will get traffic from home networking hobbyists and IT students. Add those negatives before launch.
After launch, review your search terms report at least weekly. Every irrelevant query that triggered your ad is a negative keyword waiting to be added. For a complete guide to this process, the Google Ads negative keywords guide goes deep on list structure, match types for negatives, and negative keyword lists at the campaign vs. account level.
Organize Keywords Into Tightly Themed Ad Groups — Not Keyword Dumping Grounds
How you organize your keywords matters as much as which keywords you pick. Google rewards relevance: between your keyword, your ad, and your landing page. That alignment directly affects your Quality Score, your CPCs, and — most importantly — your conversion rate.
The rule: one tight theme per ad group. If you’re selling HVAC services, “emergency AC repair,” “AC not cooling,” and “air conditioner repair service” belong in the same ad group. “Furnace installation cost” does not — that’s a different intent, different ad copy, probably a different landing page.
Resist the urge to throw 40 keywords into a single ad group because they’re vaguely related. Every keyword-to-ad mismatch costs you money twice: once in lower Quality Scores (higher CPCs), and again in lower conversion rates (searchers who land on a page that doesn’t match what they were looking for).
A well-organized account also makes optimization dramatically easier. When an ad group is tightly themed, you can actually diagnose performance — you know exactly what the traffic is, what the ad says, and what the landing page promises. When an ad group is a catch-all, you’re troubleshooting in the dark.
Where Keyword Planner Stops and Real Research Begins
Keyword Planner shows you what people search for. It doesn’t tell you what those searches actually mean for your business, which ones your competitors are dominating, or which ones are worth the CPC given your margins.
Here’s where to go beyond Keyword Planner:
Your own search terms report (if you have one)
If you’ve run Google Ads before — even a messy, inefficient campaign — your historical search terms report is gold. It shows you the actual queries that triggered your ads and which ones converted. That’s real market data that no tool can replicate. The search terms report is one of the most underused tools in Google Ads — most advertisers glance at it, when they should be mining it systematically every week.
Competitor analysis
Tools like SEMrush, SpyFu, and Ahrefs let you see what keywords your competitors are bidding on and what their ads look like. This doesn’t mean you should copy their strategy — sometimes competitors are wasting money on the same bad keywords everyone else chases. But it surfaces terms you may have missed and tells you where competition is concentrated. For a deeper take on the tactics and economics of bidding against competitors, see our guide on competitor keyword targeting in Google Ads.
Sales and customer service language
The best keyword research happens in conversations with your sales team. Ask them: “What’s the first thing prospects say when they call?” “What problems do they describe?” “What words do they use that are different from how we describe the product?” That language becomes keywords. This is especially critical for B2B and professional services, where industry jargon diverges sharply from how buyers actually search. If you run professional services, our Google Ads playbook for professional services covers how to translate service offerings into search intent that actually converts.
Google’s own suggestions (with skepticism)
When you type a query into Google, the autocomplete suggestions and “related searches” at the bottom of the page reflect real search behavior. Spend 20 minutes manually searching your core keywords and documenting what Google suggests. It’s not scientific, but it’s a fast, free way to surface long-tail variations you’d never find in Keyword Planner.
FAQ: Google Ads Keyword Research
How many keywords should I have in a Google Ads campaign?
There’s no magic number, but quality beats quantity every time. A campaign with 20 tightly targeted, high-intent keywords will consistently outperform one with 200 loosely related terms. Most well-built ad groups contain 5–15 keywords. If you find yourself adding keywords just to fill out a list, stop. That’s how bloated, unmanageable campaigns are born.
Is Google Keyword Planner free?
Yes — it’s accessible to any Google Ads account, including accounts that aren’t actively running campaigns. However, accounts with active spend get more precise search volume data. If your account isn’t spending, you’ll see volume ranges (1K–10K) instead of exact numbers. Running even a small campaign unlocks better data.
What’s the difference between PPC keyword research and SEO keyword research?
They overlap but they’re not the same. SEO keyword research optimizes for traffic and content relevance over months. PPC keyword research optimizes for paid conversions right now, which means you care much more about commercial intent and much less about informational volume. You also care about CPC, competition level, and what the search results page looks like — if every result is an ad, you’re entering a competitive market. If organic results dominate, you may be able to buy clicks cheaply because few advertisers are bidding.
Should I bid on branded keywords (my own brand name)?
Almost always yes. Branded campaigns typically deliver your lowest CPCs, highest conversion rates, and highest Quality Scores. Competitors can and do bid on your brand name — if you’re not defending that space, you’re handing them warm leads who were already looking for you specifically. The ROI on branded campaigns is almost always exceptional.
How often should I update my keyword list?
Weekly review of your search terms report should be standard practice. Add negatives for irrelevant queries, and flag any high-volume converting terms that aren’t already on your keyword list. Beyond that, do a broader keyword strategy review quarterly — new competitors enter markets, search behavior shifts, and your own offerings change. Treating keyword research as a set-it-and-forget-it task is one of the most common reasons campaigns plateau.
What’s a good starting keyword strategy for a brand new account?
Start narrow: exact match only, bottom-funnel terms, tightly themed ad groups. Prove conversion economics first. Once you have 30–50 conversions and you understand your cost per conversion relative to what a customer is actually worth, you can expand to phrase match and test carefully into broader terms. Resist the pressure to “get more volume” before you’ve proven the foundation converts. For a full roadmap on this approach, see our guide on what to do in the first 90 days of a new Google Ads account.
The Bottom Line on PPC Keyword Strategy
Keyword research for Google Ads is the foundation that every other optimization sits on. Get it right, and smart bidding has good signals to work with. Get it wrong, and you’re asking an algorithm to optimize its way out of a structurally broken campaign — which it can’t do.
The framework here isn’t complicated. Start with buyer intent. Use Keyword Planner as a starting point, not a final answer. Apply match types deliberately. Build your negative list before launch. Organize keywords into tight, themed ad groups. And treat your search terms report as a weekly source of truth that keeps your strategy calibrated to what the market is actually doing.
If you’ve gone through this process and your campaigns still aren’t converting the way they should, the issue is often downstream — landing page relevance, conversion tracking accuracy, or bid strategy configuration. A thorough account audit usually surfaces it quickly. If you want an outside perspective, our step-by-step Google Ads account audit checklist covers the exact diagnostic process we run for every new client.
And if you’re currently working with an agency and wondering whether your keyword strategy is actually being managed strategically — ask them to walk you through their keyword research process. A strong agency should be able to explain their intent framework, their match type rationale, and how they’re using search terms data to refine the list over time. If they can’t, that’s a signal worth paying attention to.
