Gaps from your site.
Not a generic database.
SiteRooster doesn’t guess at topics. It reads your site, extracts your core keywords, analyses what’s currently ranking for them, and surfaces the content you’re missing.
Topic Extraction
Every page on your site parsed for topics, keywords, and themes. Your existing coverage mapped in detail.
SERP Analysis
For each of your target keywords, the pages currently ranking are analysed to see what they cover that you don’t.
Gap Detection
Two gap types surfaced: topics with no coverage at all, and pages that could expand to rank for adjacent queries.
Scoring & Ranking
Each gap scored on four dimensions. Priority band assigned. Nearest-match URL on your site shown for every gap.
Every gap scored on
four hard metrics
No vibes. Every gap gets a measurable score so you can rank and sort by what actually moves the needle.
Opportunity Score
Composite score combining volume, difficulty, and fit. The headline number to sort by when deciding what to write next.
Content Fit
How well the topic matches your existing site’s themes. Higher fit means easier to rank and faster to write.
Search Volume
Monthly searches from industry clickstream data. Know the audience size before you invest the effort.
Keyword Difficulty
How hard it is to rank. Calculated from live SERP competition for the target keyword, not a static historical estimate.
Priority Band
Automatically tagged High, Medium, or Low based on opportunity, effort, and fit with your existing site.
Emerging Topics
Gaps gaining search volume flagged with a lightning bolt. Catch trends before the competition covers them.
