Content Gap — finding missing keyword opportunities
Discover keywords you're missing or underperforming on, from GSC and competitor analysis
What is Content Gap?
Content Gap analysis finds keywords you're missing out on — queries people search but your site either doesn't rank for or ranks poorly enough to miss most traffic.
Two sources of Content Gap
1. From GSC (your own data)
Keywords where you appear but rank > position 10 (page 2, 3...) — "low-hanging fruit" if you improve the content.
Filter: Position > 10, Impressions > 100 (indicates real traffic potential).
2. Competitor analysis
Enter a competitor domain → SigoMark analyzes their sitemap + content → finds topics they cover that you don't.
Competitor analysis requires Pro/Agency plan.
Taking action from Content Gap
Each gap item has a "Create keyword from this gap" button — click to add the keyword to your project and start the AI pipeline.
Priority score
SigoMark calculates a Gap Score = (Impressions × 0.4) + (1/Position × 0.6) — keywords with high traffic potential close to the top get highest priority.
