How to Find High-Performing Keywords in Google Ads (Step-by-Step)

TL;DR: Finding high-performing keywords isn't about collecting the most keywords—it's about finding the right ones. This guide walks you through a repeatable, seven-step process to identify keywords that actually drive conversions, not just clicks. Whether you're managing your own campaigns or handling accounts for clients, these steps work whether you're starting from scratch or cleaning up an existing campaign. By the end, you'll know exactly where to look, what signals to trust, and how to cut the noise from your keyword strategy. No fluff—just a practical workflow you can run today.

Most advertisers approach keyword research backwards. They open a keyword tool, pull a list of high-volume terms, add them all to a campaign, and wonder why the results are mediocre. The real data—the kind that tells you what actual users searched before converting—is already sitting inside your Google Ads account. You just need to know where to look and what to do with it.

This guide covers the full process: from mining your own account data, to validating demand, filtering by intent, applying match types, and building a weekly review habit that keeps surfacing winners over time.

Step 1: Start With Your Search Terms Report, Not a Keyword Tool

In most accounts I audit, the Search Terms Report is the most underused asset in the entire interface. Advertisers spend money on third-party tools when the best keyword intelligence they have is already inside Google Ads, generated by real users who clicked their actual ads.

To access it: navigate to Campaigns > Insights & reports > Search terms in your Google Ads account. What you're looking at is a list of the actual queries that triggered your ads—not the keywords you're bidding on, but the real searches people typed.

That distinction matters more than most people realize. You might be bidding on "project management software," but your ads could be triggering for "free project management app for students"—a very different audience with very different intent.

Here's what to look for when you open this report:

Conversions first: Sort the report by conversions descending. The search terms at the top of that list are your actual high-performers. These are real queries from real people who took the action you care about.

Cost-per-conversion: Cross-reference with cost to find efficiency winners. A search term with three conversions at a low CPA is often more valuable than one with ten conversions at a high CPA, depending on your targets.

CTR patterns: High CTR on a search term suggests strong ad relevance. When that's paired with conversions, you've found something worth promoting to an explicit keyword.

The common pitfall here is ignoring this report entirely and relying only on keyword tools for discovery. Those tools give you estimates and projections. The Search Terms Report gives you evidence. Start there, every time.

Once you've identified search terms that are converting, finding new keywords from your search terms report becomes a repeatable process you can run on a weekly cadence.

Step 2: Define What "High-Performing" Actually Means for Your Campaign

This sounds obvious, but it's where a lot of campaigns go wrong. "High-performing" is relative—and if you don't define it before you start filtering, you'll end up optimizing for the wrong thing.

Before you touch another keyword, write down your primary success metric. Is it:

CPA (Cost Per Acquisition): What's the maximum you can pay for a lead or sale while staying profitable?

ROAS (Return on Ad Spend): For ecommerce, what revenue multiple do you need to justify the spend?

Conversion rate: Are you optimizing for volume or efficiency?

CTR: Only relevant as a secondary signal—a keyword with high CTR and zero conversions is not high-performing. Full stop.

What usually happens here is that advertisers look at CTR or impression share and assume a keyword is working. But a keyword that drives clicks without conversions is just burning budget. The metric that defines performance is always downstream of the click.

A practical way to set your benchmark: look at your top 10 to 20 percent of converting keywords. What do they have in common? Look at their phrasing, their specificity, their match type, and the intent they signal. You're building a profile of what a good keyword looks like in your account.

Commercial intent signals in keyword phrasing are worth paying attention to here. Experienced PPC managers know that queries containing words like "buy," "hire," "price," "best [product] for [use case]," or "near me" tend to indicate higher purchase intent. These aren't guarantees, but they're useful filters when you're scanning a large keyword list.

One more thing: the definition of high-performing shifts depending on your campaign type. For lead gen, a high-performing keyword drives form fills or calls at a target CPA. For ecommerce, it drives purchases at a target ROAS. If you want a deeper framework for this, prioritizing keywords by ROI potential gives you a structured way to rank candidates before committing budget. Be explicit about your goal before you start auditing. Otherwise you're just sorting numbers without context.

Step 3: Use Google's Keyword Planner to Validate and Expand

Keyword Planner is a useful tool—but most people use it wrong. They treat it as a cold discovery engine, plugging in a broad topic and hoping for keyword inspiration. That's not where it shines.

Keyword Planner's best use case is validation: you've already identified promising search terms from your Search Terms Report, and now you want to understand demand, competition, and seasonality before you invest further.

Here's the workflow:

1. Take the top-converting search terms from Step 1 and use them as seed keywords in Planner's "Discover new keywords" tool.

2. Filter the results by relevance to your offer—not just by volume. A keyword with lower search volume but high commercial relevance is often more valuable than a high-volume term with ambiguous intent.

3. Check the competition column. In Keyword Planner, "competition" reflects how many advertisers are bidding on a term. High competition is often a proxy for commercial value—it means other advertisers have decided this keyword is worth paying for.

4. Review suggested bid ranges. These give you a rough sense of what the market is paying for a click. If the suggested bid aligns with your economics, that's a green light to test.

5. Look at the seasonality graphs. If a keyword spikes in December and you're planning a campaign for March, that context matters for budgeting and expectations.

There's also a feature worth using: "Start with a website." You can enter a competitor's URL and Planner will surface keywords associated with that site. It's a useful way to identify gaps in your own keyword strategy.

One important caveat: Planner's volume estimates are directional, not precise. The PPC community has long acknowledged that these numbers are approximations, often grouped into ranges. Use them to compare relative demand between terms, not as exact traffic forecasts. For a more thorough approach, validating keywords using third-party tools alongside Planner gives you a more complete picture before you commit spend.

Step 4: Filter for Intent—Cut the Informational, Keep the Commercial

Not all keywords belong in a PPC campaign. The fastest way to waste budget is to bid on queries where users are in research mode, not buying mode.

The four intent types you need to know:

Informational: The user wants to learn something. "What is Google Ads," "how does PPC work," "what are negative keywords." These belong in content marketing, not paid search.

Navigational: The user is looking for a specific website or brand. "Google Ads login," "HubSpot dashboard." Usually not worth bidding on unless it's your own brand.

Commercial: The user is researching options before making a decision. "Best Google Ads optimization tool," "Google Ads agency vs. in-house." High value for advertisers who can position well at this stage.

Transactional: The user is ready to act. "Buy Google Ads management software," "sign up for PPC tool," "Google Ads Chrome extension." These are your highest-priority keywords.

For most PPC campaigns, you want commercial and transactional intent. Informational queries typically produce low conversion rates because the user isn't ready to act yet.

A practical filtering method: scan your keyword list for question-based phrasing ("what is," "how does," "why do") and flag those as likely informational. Then use negative keywords to block them before they trigger your ads.

This is also where keyword clustering becomes valuable. Instead of just grouping keywords by topic, group them by intent. A cluster of transactional keywords gets one ad copy and landing page. A cluster of commercial-intent keywords gets a different message that speaks to comparison and decision-making. Matching the ad and landing page to the intent of the query is one of the clearest patterns in high-performing campaigns.

To validate intent, go back to the Search Terms Report from Step 1. What did users actually do after clicking? If a query consistently drives clicks but no conversions, that's a strong signal the intent doesn't match your offer—regardless of how relevant the phrasing looks on the surface. For a focused breakdown of this process, finding high-intent keywords for PPC walks through the exact signals to look for.

Step 5: Apply Match Types Strategically to Test and Refine

Match type is one of the most consequential decisions you make for any keyword, and it's one of the most frequently mishandled. The match type you choose determines which search queries trigger your ads—and therefore which keywords actually "perform" in your account.

A quick recap of how each type behaves:

Broad match gives Google the most flexibility to match your keyword to related queries. It can surface unexpected winners, but it can also bleed budget on irrelevant traffic if you're not actively monitoring the Search Terms Report.

Phrase match requires the meaning of your keyword to be included in the search. It offers a middle ground between reach and control. In practice, phrase match tends to be the right starting point for new keywords you haven't tested yet.

Exact match restricts your ads to searches that match the exact term or close variants. Once you've confirmed a keyword converts, exact match gives you precise control over bidding and ad relevance.

The recommended testing approach for most campaigns: start new keywords on phrase match. This gives you enough reach to gather data without completely handing control to Google's matching algorithm. Once a phrase match keyword demonstrates consistent conversions, promote the specific search term to an exact match keyword in its own ad group with a dedicated bid.

Here's the actual workflow:

1. Identify a converting search term in your Search Terms Report.

2. Add it as an explicit exact match keyword to the most relevant ad group.

3. Assign a bid that reflects its proven conversion value.

4. Add the original phrase match keyword as a negative to that ad group if needed, to prevent cannibalization.

One rule that experienced PPC managers follow consistently: never add a keyword without deciding its match type first. The default in Google Ads is broad match, and broad match without active monitoring will expand into irrelevant territory quickly. Adding converting search terms as keywords with the right match type from the start is one of the highest-leverage habits you can build. Decide intentionally, every time.

Step 6: Build a Negative Keyword List to Protect Your Winners

Finding high-performing keywords is only half the job. The other half is protecting them from irrelevant traffic that dilutes your budget and distorts your performance data.

Here's the thing: every irrelevant click that burns budget is also competing with your high-intent traffic for impression share and budget allocation. Negative keywords don't just save money—they sharpen the signal in your account, making it easier to identify what's actually working.

How to identify negative keyword candidates:

Zero-conversion search terms with significant spend: Open your Search Terms Report, filter for search terms that have spent above a meaningful threshold and delivered zero conversions. These are your first candidates for negatives.

Irrelevant industry terms: If you're selling B2B software and your ads are triggering for consumer-facing queries, those terms belong on a negative list immediately.

Wrong audience signals: Terms like "free," "DIY," "student," or "entry-level" often indicate an audience that isn't aligned with your offer. Add them as negatives if they're not converting.

When it comes to where to add negatives, the level matters:

Campaign-level negatives block a term across all ad groups in that campaign. Use this for terms that are universally irrelevant to your campaign's purpose.

Ad group-level negatives block a term only within a specific ad group. Use this for terms that might be relevant in one context but not another.

For agencies managing multiple accounts, managing negative keywords across multiple campaigns with shared lists is a significant time-saver. You can build a master list of irrelevant terms and apply it across all client accounts simultaneously, rather than adding negatives account by account.

The practical recommendation: review your Search Terms Report weekly and add negatives proactively. Don't wait for wasted spend to accumulate before you act. A consistent weekly review habit will do more for your account efficiency than any one-time cleanup.

Step 7: Create a Weekly Review Workflow to Keep Finding Winners Over Time

High-performing keywords aren't a one-time discovery. They shift with seasonality, competition changes, and evolving audience behavior. What converts well in January might underperform in July. A competitor entering the market can change the economics of a keyword overnight. Google's matching behavior evolves constantly, especially with broad match.

The mistake most agencies make is treating keyword research as a setup task rather than an ongoing practice. You find some good keywords at launch, set the campaign live, and move on. Six weeks later, the Search Terms Report is full of irrelevant queries that have been quietly burning budget.

Here's a simple weekly workflow that takes less time than you'd expect:

1. Open your Search Terms Report and sort by conversions for the past seven days.

2. Identify any new converting search terms that aren't already explicit keywords in your account. Promote them.

3. Identify search terms with spend and zero conversions. Add the relevant ones as negatives.

4. Check match type assignments. Are your top converters on exact match? Should any phrase match keywords be tightened?

5. Review your CPA or ROAS trends using Google Ads' date comparison feature. Is performance improving week over week? If not, the Search Terms Report is usually where you'll find the reason.

This workflow is straightforward in principle but can be slow in practice—especially if you're managing multiple accounts and doing everything manually through the native Google Ads interface. Exporting to spreadsheets, cross-referencing lists, and then re-importing changes eats time that compounds across a client roster.

Tools like Keywordme are built specifically for this workflow. It's a Chrome extension that lives directly inside your Google Ads Search Terms Report, letting you remove junk search terms, promote converting queries to keywords, apply match types, and build negative keyword lists with single clicks—without leaving the interface or touching a spreadsheet. For agencies running weekly reviews across multiple accounts, that kind of in-interface efficiency changes how much you can actually get done in a session.

Set a calendar reminder for your weekly keyword review. Consistent audits done regularly outperform one-time deep dives every time. The account that gets reviewed every week will always outperform the one that gets a thorough audit once a quarter.

Your Weekly Keyword Optimization Checklist

Here's a quick summary of the full process you can reference each week:

Step 1: Search Terms Report first. Always start with real data from your own account before reaching for any external tool.

Step 2: Define your success metric. CPA, ROAS, or conversion rate—know your benchmark before you filter anything.

Step 3: Validate with Keyword Planner. Use it to confirm demand and surface gaps, not as your primary discovery source.

Step 4: Filter by intent. Keep commercial and transactional. Cut informational. Use negatives to enforce the boundary.

Step 5: Apply match types deliberately. Start with phrase match, graduate to exact match once performance is confirmed.

Step 6: Build and maintain your negative keyword list. Protect your winners by blocking irrelevant traffic proactively.

Step 7: Run the weekly review. Promote converters, add negatives, check match types, compare trends. Repeat.

This process is iterative by design. There's no finish line—just a rhythm of finding what works, protecting it, and building on it over time. The advertisers who consistently outperform in Google Ads aren't the ones who did the best initial keyword research. They're the ones who review their accounts regularly and act on what they find.

If you want to make the weekly workflow faster, Keywordme handles the repetitive parts directly inside your Search Terms Report.
