FAQ
What is a content gap?
A content gap is a topic or keyword that your competitors rank for (or cover in their content) but you don't. Finding gaps helps you identify content opportunities — pages you should write or expand to capture traffic your competitors are getting.
How many competitors can I compare?
Up to 3 simultaneously. Comparing more than 3 dilutes the signal — the keywords all 3 competitors share that you don't have are the highest-priority gaps.
How is priority calculated?
Priority is a 0-100 score. Each gap gets: (number of competitors covering it × 25) + min(25, total count across competitors). So a gap covered by all 3 competitors with high frequency scores near 100. A gap in only 1 competitor with count 1 scores ~26.

(1) Multi-competitor comparison (up to 3). (2) Keyword overlap percentage. (3) Gap priority scoring (0-100). (4) Unique keyword detection (in yours not in competitors). (5) Shared keyword list.
