What is Content gap?

A content gap is a question your audience asks — and competitors answer — that your site does not cover, or covers too thinly to compete for.

Why it matters

Gaps are where the cheapest wins are. Improving a page already ranking fourth is incremental; publishing the only credible answer to a question nobody in the category has addressed well is how a site earns ground it did not have. In AI answers the effect is sharper still, because an engine assembling a response draws from whoever covered the question at all.

How it works in practice

Finding gaps means comparing coverage rather than keywords. The useful comparison set is the pages competitors rank for and the sources AI engines actually cite for category questions — the second often surfaces publications and question framings that keyword tools miss entirely, because the engine is answering an intent rather than matching a phrase.

Not every gap is worth filling. A gap that exists because the question has no commercial relevance, or because answering it credibly requires expertise or data you do not have, is a gap you should leave. The ones worth taking are where you can say something specific and verifiable that the existing answers do not.
