Start here · What is a content gap?
A content gap is something your audience expects but your page or site does not cover well enough.
Gaps can be missing topics, questions, comparisons, definitions, examples, media, schema, or internal links.
Content gap mapping helps you improve pages strategically instead of adding random paragraphs just to make them longer.

FAQ
- Should I copy every topic competitors cover?
- No. Cover what helps your audience and supports the page intent. Some competitor sections are filler.
- Can content gaps become new pages?
- Yes. If a gap represents a distinct intent, it may deserve its own page instead of one added section.
- How many competitors should I compare?
- Three to five strong pages are usually enough for a first pass. More can create noise.
