GUIDE · PART OF SEO COMPETITOR INTELLIGENCE
Content gap analysis:
find what you haven't covered.
A content gap is something your buyers look for that your site doesn't answer and somebody else's does. Finding them used to mean comparing keyword lists. It now means checking AI answers too, because a rival can be named there for a question that barely registers in search. This guide covers how to find the gaps and how to decide which are yours to fill.
What is a content gap analysis?
A content gap analysis is a comparison between what your site covers and what your audience looks for, usually measured against competitors. It turns up three kinds of gap. A keyword gap is a search your rivals rank for and you don't. A topic gap is a subject you haven't covered at all. An answer gap is a question where AI engines name a competitor and leave you out. The output is a short list of pages to write or improve.
Key facts
- A content gap is demand your site doesn't meet and a competitor's does
- There are three kinds: keyword gaps, topic gaps and gaps in AI answers
- Your competitors in AI answers can differ from your competitors in search, so check both
- A gap is only worth filling if it's relevant to what you sell and you have something of your own to say
- Many gaps are better closed by improving a page you have than by writing a new one
- SEORCE finds content opportunities from your rankings and from what competitors cover, and shows who AI names in your place

A gap list can run to thousands.
Compare your site with three competitors and you'll get a spreadsheet of every keyword they rank for and you don't. Most of it is noise. The skill is in the filtering.
Every keyword a rival ranks for
Much of it is their brand, their unrelated products, or topics you'd never want.
The AI gap is invisible
A keyword comparison can't show a question where an assistant names your rival.
The reflex to write
Plenty of gaps are already half-covered by a page of yours that needs improving.
Three kinds of gap, and how to sort them.
Find all three, then cut the list hard. Ten gaps you act on are worth more than a thousand you file.
Look in three places.
Each kind of gap shows up in different data. Checking only one leaves the others unseen.
- Keyword gapsSearches where competitors rank and you don't appear.
- Topic gapsWhole subjects they cover that you've never written about.
- Answer gapsBuyer questions where AI engines name them and leave you out.
Cut what isn't yours.
This is where most of the value is. A gap deserves a place on your list only if it passes three tests.
- Is it relevant?Does it connect to something you sell or know?
- Can you win it?Do you have a product, experience or data that gives you a right to the answer?
- Is it worth it?Is the buyer close enough to a decision to justify the work?
Write, improve or leave.
For each gap that survives, check whether you already have a page near it. That decides the kind of work.
- WriteNothing of yours covers it.
- ImproveA page exists and doesn't go far enough.
- LeaveA competitor owns it for good reason, and it isn't central to you.
Running one, start to finish.
Pick competitors carefully. The wrong three will send you after gaps that don't matter.
Choose your competitors
From search results and from AI answers. They aren't always the same companies.

Keywords, topics and the buyer questions where you're missing.
Content opportunities →Filter
Relevant, winnable and worth it. Expect to discard most of the list.
See how a rival's page is put together.
Open a competitor's page with the extension and its outline, title and schema are laid out for you. It's the quickest way to see what they cover that you don't.
Three gaps, and what each becomes.
| Kind of gap | How you find it | What it usually becomes |
|---|---|---|
| Keyword gap | Compare the searches each site ranks for. | A new page, or a section added to an existing one. |
| Topic gap | Compare the subjects each site covers. | A new guide, or a small group of pages. |
| Answer gap | Ask AI engines your buyers' questions and see who is named. | A direct answer on a page of yours, and work on the sources engines cite. |
Gaps from your own data, ready to brief.
Content Studio finds content opportunities from your rankings and from what competitors cover. Each is tagged as a competitor gap, a ranking opportunity or a high-volume topic, and arrives with a template suggested. AI Beacon adds the third kind of gap: the buyer questions where engines name a competitor in your place.
Frequently asked questions.
A content gap analysis compares what your site covers with what your audience looks for, usually against competitors, to find subjects and questions you haven't answered.
Look in three places: the searches competitors rank for and you don't, the subjects they cover and you haven't, and the buyer questions where AI engines name them in your place.
Three to five. Fewer and you miss gaps. More and the list fills with noise. Choose from both search results and AI answers.
No. Most gaps should be discarded as irrelevant or unwinnable. Of the rest, many are better closed by improving a page you already have.
A keyword gap is one kind of content gap: a search a competitor ranks for and you don't. Content gaps also include whole topics you haven't covered and AI answers you're missing from.
Each quarter is enough for most sites. Run one sooner when a new competitor appears or you launch into a new area.
For individual pages, yes. The SEORCE browser extension shows the outline and markup of any page, including a competitor's. Comparing whole sites needs ranking data, which the free tools don't have.
See what competitors cover that you don't.
Add your site and up to five competitors. The content opportunities appear first, each tagged with the kind of gap it is.
