How do I find keywords competitors rank for but I don't?

Use a keyword or content gap tool with three to five competitor domains, then filter out branded terms and low-volume searches to leave a list of real, addressable gaps.

How to Run an E-commerce Competitor Gap Analysis That Finds Real Growth

Q: What is an SEO competitor gap analysis?

Finding searches your competitors rank for and you do not, across keywords, missing collections, thin content and internal linking, turned into a prioritised build list.

Quick answer

A competitor gap analysis finds the searches your rivals rank for and you do not, then turns them into a prioritised list of pages to build or fix. You pull every keyword three to five competitors rank for, filter out their brand terms and anything under about 50 searches a month, and what remains is your gap. The real value is bucketing each gap into an action: a new collection to create, an existing page to optimise, or a guide to write, prioritised by search volume and buying intent.

The fastest way to find growth on an e-commerce site is rarely to invent new ideas. It is to see exactly where your competitors are winning searches you are absent from, and copy the ones worth copying. On a pet e-commerce brand I worked on, the single most useful exercise was not a keyword brainstorm. It was a systematic comparison against two rivals that revealed the brand had a fraction of the category pages they did, and was invisible for dozens of high-volume terms simply because no page existed to rank. That is a gap analysis, and done properly it writes your roadmap for you.

It Is Not Just a Keyword Gap

Most guides frame this as a keyword gap and stop there. On an e-commerce site the gap has several layers, and the keyword list is only the surface of it. The comparison that actually drives growth looks at all of them.

A gap analysis turns every term your rivals rank for into a prioritised list of pages to build or fix. Illustrative.

The keyword gap

The classic version: terms your competitors rank for and you do not. This is the raw material, pulled from a gap tool with three to five rival domains. On its own it is a long, messy list, which is why the filtering below matters more than the pulling.

The collection and page-type gap

Often the biggest one. Competitors frequently have dedicated collection pages for categories you have never built, so they rank for the head term and you have nothing to show. Counting their collections against yours reveals whole categories of demand you are absent from.

The content-depth gap

For terms you both target, look at how much better the ranking page is: richer descriptions, better images, specifications, buying guidance, reviews. Sometimes the gap is not a missing page, it is a thin one that a stronger competitor page outranks.

The internal linking gap

Competitors often interlink their categories and products far more deliberately than you do, routing authority to the pages that matter. A gap here is invisible in a keyword tool but shows up when you compare how each site links its own pages together.

“The most valuable output of a gap analysis is not a keyword list. It is a prioritised list of pages to build, each one a category of demand a competitor is capturing and you are not.”

The Method, Step by Step

The process is simple to run and easy to do badly, because the raw output is enormous and most of it is noise. The discipline is in the filtering and the bucketing, not the pulling.

The e-commerce gap analysis method:

Pick three to five genuine competitors, the sites that actually outrank you for your commercial terms, not just the biggest brands
Pull every keyword they rank for that you do not, using a gap or content-gap tool
Filter out their branded terms, and set a minimum search volume so you are not chasing terms nobody searches
Bucket each remaining gap into an action: build a new collection, optimise an existing page, or write a supporting guide
Compare collection counts and page types directly, to surface whole categories you have no page for
Prioritise the buckets by search volume and buying intent, and work the highest-value gaps first

What you end up with is not a report that sits in a drawer, it is a build queue. Each item is a specific page tied to real demand a competitor is already proving exists. That is the difference between a gap analysis that generates growth and one that generates a spreadsheet: the good one ends in pages shipped, in priority order, against demand you can see.

Common Questions

What is an SEO competitor gap analysis?

It is the process of finding the searches your competitors rank for and you do not, so you can see exactly where demand is going to rivals instead of you. On an e-commerce site it covers keyword gaps, missing collection and category pages, thin content, and internal linking gaps, and it turns into a prioritised list of pages to build or improve.

How do I find keywords my competitors rank for but I don’t?

Use a keyword gap or content gap tool, enter three to five competitor domains, and pull the terms they rank for that you do not. Then filter out their branded terms and low-volume searches so you are left with a manageable list of real, addressable gaps rather than thousands of irrelevant terms.

How many competitors should I use for a gap analysis?

Three to five genuine search competitors, meaning the sites that actually outrank you for your commercial terms, not simply the biggest names in your market. Too few misses gaps; too many produces noise. The point is to find terms that several relevant rivals rank for and you do not, which signals real, proven demand.

What do I do with the gaps once I find them?

Bucket each one into an action and prioritise. Some gaps are new collections or category pages you should create, some are existing pages to optimise or deepen, and some are supporting guides to write. Order them by search volume and buying intent, and work the highest-value gaps first so the analysis ends in pages shipped, not a spreadsheet.

Want to know exactly where your competitors are beating you?

A gap analysis turns your rivals’ rankings into your roadmap: the collections to build, the pages to fix, the guides to write, in priority order. I run these for e-commerce brands and hand you a build queue tied to real demand.
