Keywords they rank for, you don't

Keywords where they outrank you

Searches you already rank for, but below your competitors. These are often the fastest wins.

What is a keyword gap analysis?

A keyword gap analysis compares the keywords your website ranks for on Google with the keywords your competitors rank for. The searches they win and you don't are your keyword gap.

It is the fastest way to find content opportunities that are proven. Your competitors already get traffic and customers from these searches, so you know people in your market look for them.

The same questions people type into Google are the questions they ask ChatGPT, Perplexity and Gemini. The pages that rank for them are usually the pages AI answers cite, so closing a keyword gap helps you in both places.

How to turn keyword gaps into rankings, AI mentions and customers

A keyword gap report can hold thousands of terms. Most of them will never bring you a customer. This is how we pick the ones that will, for the 70+ companies our agency runs SEO and AEO for.

The short version
  • Filter for buying intent before you look at search volume.
  • Fix the keywords where you already rank on page two before you write anything new.
  • Write one page per search intent, better than what ranks today, and readable for AI search.
  • Judge the work by leads and customers, not by keyword count.

1. Filter for buying intent first

Sort every keyword into one of three buckets before you look at a single number:

  • Buying keywords: "best [category] for [industry]", "[competitor] alternatives", "[you] vs [competitor]", "[service] pricing", "[service] in [city]". People searching these are choosing a vendor.
  • Problem keywords: "how to fix", "why does", "how to choose". People with the problem you solve, earlier in the journey.
  • Everything else: definitions, news, tangents. Useful for awareness, rarely for customers.

Start with buying keywords, even when they show 30 searches a month. Ten buyers a month beat ten thousand readers who will never buy. It's where our clients see first results, often in 2 to 3 weeks rather than the 6 to 12 months people expect from SEO.

2. Start with the keywords several competitors rank for

If one competitor ranks for a term, it might be luck. If three of them do, your market searches for it and Google expects pages like yours to answer it. Those keywords go to the top of the list.

3. Win the keywords you almost have

Keywords where you rank 8 to 30 and a competitor ranks higher are your fastest wins. You already have a page Google considers relevant. Improve it instead of starting from zero:

  • Answer the search directly in the first two sentences.
  • Add what the higher-ranking page covers and yours doesn't.
  • Add the details only you can give: prices, examples, results, screenshots.
  • Link to it from your related pages with the keyword in the anchor text.

4. Match what Google already rewards

Look at the page that ranks for each keyword before you write. If the results are comparison tables, a long blog post won't rank. If they are product pages, an article won't either. Match the format, then make yours clearly better.

5. Write one page per intent, not one page per keyword

Group keywords that mean the same thing into one page: "SEO audit", "SEO audit service" and "website SEO check" belong together. Separate pages for each variation compete with each other and none of them ranks well.

6. Make every new page readable for AI search

The pages that rank on Google are usually the pages ChatGPT, Perplexity and Google's AI Overviews cite. Give them a reason to quote you:

  • Open each section with a direct, specific answer in one or two sentences.
  • Use real numbers, real prices and real examples instead of general advice.
  • Keep the main content in the HTML, and add FAQ structured data where it fits.

SEO and AEO are the same game. A page built this way ranks and gets cited.

7. Don't copy what competitors wrote

A rewritten version of the page that ranks first gives Google no reason to rank yours. Add what only you know: your experience with customers, your own data, honest opinions on what works. That is also what AI answers look for when they choose which source to trust.

8. Measure customers, then re-run the analysis

Rankings and traffic are how you get there. The result is customers. Track conversions on every page you publish, check whether AI answers start naming you for the same questions, and re-run the keyword gap analysis every quarter. Your competitors keep publishing, so the gap keeps moving.

Mistakes we see with keyword gaps

Chasing search volume

Big numbers rarely mean buyers. A 40-search buying keyword often brings more customers than a 4,000-search definition.

One page per keyword

Close variations on separate pages compete with each other. Group them into one strong page.

Copying the top result

A rewrite of what already ranks gives Google and AI no reason to pick you. Add what only you know.

Ignoring near-wins

Updating a page on position 12 is faster than ranking a new one from nothing.

Keyword gap analysis questions

Is the keyword gap analysis tool free?

Yes. Enter your domain, your country and your competitors and you get your keyword gaps at no cost.

What is a keyword gap?

A keyword gap is a search your competitors rank for on Google and you don't, or where they rank higher than you. These are proven opportunities, because people in your market already search for them.

How many competitors should I compare against?

Three to five. Pick the companies that show up when your buyers search, not only the biggest brands in your market.

Which keywords from the gap should I target first?

Buying keywords that two or more competitors rank for, then the keywords where you already rank on page two or three. Those bring customers fastest.

Does keyword gap analysis help with AI search?

Yes. The questions people search on Google are the questions they ask ChatGPT, Perplexity and Gemini, and the pages that rank are usually the pages AI answers cite.

How often should I run a keyword gap analysis?

Every quarter, and whenever a new competitor starts showing up in your search results or AI answers.
