Content gap
What is a content gap?
A content gap is a topic, question or keyword that your audience searches for but your site doesn’t cover well or at all, often one that competitors already rank for. Content gap analysis is the process of finding those gaps, usually by comparing the keywords your site ranks for with those of competing sites.
Gaps come in a few forms: topics you have never covered, topics covered too thinly to rank, missing stages of the buying journey (for example, plenty of beginner guides but no comparisons), and missing formats, such as a calculator or template that searchers expect.
Why content gap matters for SEO
Closing content gaps is one of the most reliable ways to find new traffic, because competitors have already proved there is demand and that the topic can rank. It also builds topical authority, because each gap you fill makes your coverage of a subject more complete.
In AI search, gaps show up as prompts where competitors are cited and you aren’t. The cited pages often reveal exactly what is missing.
How to do a content gap analysis
- List three to five real organic competitors: sites that rank for your keywords, not just business rivals.
- Run a keyword gap report to find keywords they rank for and you don’t.
- Filter out irrelevant terms and group the rest by topic and intent.
- For each group, decide whether to create a new page or improve an existing one.
- Prioritise by search volume, business value and difficulty, then add the work to your plan.
