Before you pay for a single keyword tool, open the free one you already own. Google Search Console shows the actual queries your site appears for, with your real position, impressions, and clicks — data no third-party tool can replicate, because it comes straight from Google. Most founders use GSC to check rankings and stop there. It's actually a keyword-opportunity goldmine if you know what to look for.
Here are the four opportunities hiding in your GSC data, and how to pull each one.
Opportunity 1: Striking-distance keywords
These are the fastest wins in SEO: queries where you already rank on page 2 (positions 11–20) with meaningful impressions. Google already thinks you're relevant; you're one improvement from page 1.
To find them:
- Search results → Performance, set the date range to the last 3 months.
- Add the Average position metric and filter to position greater than 10 and less than 21.
- Sort by Impressions descending.
The queries at the top are getting shown to searchers but not clicked, because you're not on page 1 yet. Each is a quick win — pick the highest-impression one, improve the page it's on, and resubmit. This single report is the most valuable thing in GSC.
Opportunity 2: High-impression, low-CTR queries
Look for queries with lots of impressions but a low click-through rate relative to their position. If you rank in the top 5 for a query but your CTR is well below what that position should earn, the problem usually isn't ranking — it's your listing.
Filter Performance to your top-ranking queries, add the CTR column, and scan for the ones underperforming their position. Those are title and meta description problems: a vague or truncated title losing clicks it should be winning. A five-minute copy fix, no new content required.
Opportunity 3: Queries you rank for but never targeted
This is the discovery goldmine. Sort your queries and look for terms bringing impressions that you never intentionally wrote about. Google found your page relevant to a query you didn't plan for, which means there's demand you're accidentally adjacent to.
Two moves when you find one:
- If a page ranks on page 2 for an unplanned query with real impressions, consider whether to lean into it — add a section, or spin off a dedicated page targeting it properly.
- If several related unplanned queries cluster around one theme, that's a topic cluster the market is telling you to build.
Accidental relevance is proven demand you can deliberately capture.
Opportunity 4: Question queries for content ideas
Filter your queries to those containing "how," "what," "why," "can," or "does." These are the questions real people ask that already surface your site. They're ready-made content ideas validated by actual search behavior, and clean, extractable answers to them are exactly what earns featured snippets and AI citations.
How to export and work it
For anything beyond a quick look, export the data: the Export button (top right of the Performance report) gives you the full query list in a spreadsheet, where you can filter and sort more freely than in the GSC interface. Pull your top few hundred queries, then work through the four opportunities above.
What GSC can't do
Be clear about the one limit: GSC only shows queries you already get impressions for. It can't show you keywords you don't rank for at all, the true competitor gaps where you're invisible. For those, you need competitor data and the gap-analysis method. Think of it this way: GSC optimizes the demand you're already capturing; gap analysis finds the demand you're missing. You need both, but GSC is free and comes first.
The bottom line
Before spending on any keyword tool, mine the free one. Your striking-distance keywords, your CTR leaks, your accidental rankings, and your validated questions are all sitting in Search Console right now, drawn from your own real data. Work those four reports first — they're the cheapest, most reliable wins available, and you already own the tool. Then, once you've captured what you have, reach outward for the gaps you don't.
