Measure how strongly your content supports its pillars.
Topical authority comes from clusters of related pages reinforcing a central pillar. When supporting pages don't link back to the pillar, Google struggles to see you as the authority on that topic. RankForge measures it. Paste your URL — free, no account required.

What does this tool check?
What problems does this find?
The issues this check most often surfaces on real sites:
- Supporting posts that never link back to their pillar
- Thin or fragmented clusters with no clear hub
- Subpages outranking the pillar they should reinforce
What do I do after the check is complete?
To rank for a topic, your main page about it needs supporting articles that link back to it. We measured how well that support is working for each of your key pages.
- 1
Start with the pages that matter commercially
Work down the list in order of how much you care about the page, not how bad the number looks. A flagged page nobody needs to find is not worth an hour of your time.
- 2
Fix the cause, not the symptom
Most findings here are structural: a page is unreachable, under-linked, or competing with another page. Adding one contextual link from a strong, relevant page usually fixes more than editing the page itself.

Re-run this check to confirm the fix landed
The check is free and takes a couple of minutes. Re-crawling after a change is the only way to know it worked — and the full audit tracks the difference between crawls for you.
Why topical authority checker matters for SEO
Search engines reward sites that cover a topic comprehensively and cohesively — a strong pillar page surrounded by supporting content that links back to it. When that support is missing, even a well-written pillar struggles to be recognised as authoritative, and its sub-pages can end up competing with it instead of reinforcing it. Measuring and strengthening your topic clusters is how you build the kind of topical authority that compounds over time and is hard for competitors to copy. It's also one of the clearest signals that separates a thin site from a genuine authority in its niche.

Topical Authority Checker: frequently asked questions
What is topical authority?
Topical authority is how comprehensively and cohesively your site covers a subject. Search engines reward sites where a strong pillar page is surrounded and linked by supporting content on the same topic — a topic cluster.
What is a pillar page?
A pillar page is the central, authoritative page on a broad topic. Supporting articles cover sub-topics and link back to it. RankForge detects your pillars automatically and scores how well their clusters reinforce them.
What does the full audit add?
The free check scores pillar strength. A free account unlocks the specific supporting links to add, the content gaps to fill, a client-ready PDF, and weekly re-crawls.
