Free Content Audit Tool

What a website content audit tells you

Most sites grow one page at a time. A post here, a landing page there, a service page when sales asks for one. After a few years, nobody can say what the site is actually about. Search engines can, though. They read every page and build their own picture of the site's topics, whether that picture was planned or not.

A content audit makes that picture visible. This tool reads up to 100 pages from any domain and groups them by meaning, not by folder or URL path. Pages that cover the same subject cluster together even when they live in different sections of the site. Each cluster gets a name, a page count, and a Topic Strength score.

The result is a Coverage Map, and it surfaces three things a page-by-page review misses:

• Real topic groupings. The topics a site actually covers, based on what the page content says, not what the URL slug navigation claims.
• Overlap and cannibalization risk. Topics whose pages sit almost as close to a different topic as to their own. Those pages compete with each other in search.
• Structural gaps. Thin topics with one or two supporting pages, and divergent pages that belong to no topic at all. On sites larger than 100 pages, treat a thin topic as a lead to verify: the audit reads a 100-page sample, and the pages that would fill that topic may not have been in it.

How to read your Coverage Map

The Coverage Map is a radial map. The domain sits at the center. Main topics, called pillars, surround it. Subtopics branch outward from each pillar in rings: hubs, then branches. Bigger circles carry more pages. Hover any node for its page count, strength, and primary URL. Double-click a node to open the page it represents.

Topic Strength bands

Every topic is scored by asking a simple question: do this topic's pages really belong to it, or do they sit just as close to some other topic on the site? The answer falls into four bands:

• Strong (0.25+): pages sit clearly closer to this topic than to any other. A real topic.
• Moderate (0.10–0.25): clearly placed, but another topic is not far behind.
• Overlapping (0–0.10): pages sit almost equally close to another topic. These two topics are blurring together.
• Misplaced (below 0): on average, the pages sit closer to a different topic than to their own. The grouping the site implies is not the grouping the content supports.

What "competes with" means

When a topic scores below Strong, the map names the topic its pages were most often runner-up to. That rival can sit anywhere on the map, not just next door. When two topics name each other, they are strong candidates to merge into one deeper page or cluster.

Divergent pages and utility pages

Some pages stand alone. They sit far from every topic on the site, so the map lists them as divergent pages instead of forcing them into a cluster. Utility pages, such as contact, legal, and navigation pages, are set aside before grouping starts so they never distort the topic structure. The map reports how many were held out.

Why run a free content audit before planning new content

Search engines and AI assistants both reward topical depth. A site with 12 strong pages on one subject outranks a site with 40 scattered ones, and AI search engines cite sources that cover a topic thoroughly. Publishing more content onto a weak structure compounds the problem.

An audit-first workflow changes the order of operations:

1. Map the structure the site has today, including overlap and gaps.
2. Merge or split the topics that compete with each other.
3. Plan new content where coverage is thin, instead of where ideas happen to land.

Running the same audit on a competitor works just as well. Their Coverage Map shows which topics they defend deeply and which ones they only touch, which is where a smaller site can win.
