Map your site's
topical authority.
Topical authority is the dominant ranking frame in 2026. Sites that own a topic comprehensively beat sites with scattered coverage. Generate a visual map of yours. See strong clusters, weak clusters, and the gaps you didn't realize you had.
Free. First map runs without an account. Create a free account to save maps and regenerate as your site grows.
What the map shows.
A hierarchical visual of every theme your site covers, sized by depth and coloured by strength. Strong clusters look solid. Thin clusters look thin. Gaps are visible at a glance.
The tool crawls your site, clusters your articles into themes, and ranks each cluster by depth and coverage strength. The output is a tree map you can scan in 10 seconds.
Strong clusters are the topics you've earned. Thin clusters are the ones you're sort-of doing but haven't committed to. Gaps are the topics adjacent to your strong clusters that you haven't touched yet (often the highest-leverage place to publish next).
You can download the map as a PNG. People share these. Every share is a backlink and a credibility moment.

Reading the map: Strong clusters are where you compete. Thin clusters are where you decide whether to commit or cut. Gaps adjacent to your strong clusters are usually the next-best place to publish. Gaps far from your strong clusters are usually distractions.
Who this is for.
Niche site builders deciding whether to commit harder to their current themes or expand into adjacent ones.
Content marketers doing a quarterly audit who want a visual instead of a spreadsheet.
SEO consultants who need a one-glance artifact to bring into a client meeting.
Anyone who wants to humble-brag about their coverage on LinkedIn or X. The map is share-worthy.
Questions people ask.
-
Yes. PNG export in the free tier. SVG and print-quality export in the paid product.
-
The free tier shows coverage and topical depth only. It doesn't pull keyword volume or difficulty data, because those need paid sources. The paid SitePerfector product overlays competition data on top of the same map.
-
Good enough to spot patterns. Not perfect. Two articles you'd put in the same cluster might end up in slightly different ones. In the paid product the clustering is editable so you can correct it. In the free tool, treat it as a strong first draft.
-
Usually under two minutes. Larger sites (300+ articles) take longer. The crawl runs in the background and the iframe shows progress.
-
First run is free without an account. Map generation is the most expensive tool we run (full crawl plus AI clustering), so reruns within the free tier are gated to one a day per IP. With a free account you get more. The paid product runs maps weekly and tracks coverage changes over time.
