Competitor Topic
Coverage Analyzer

Most content gap tools require you to input a keyword or topic. This tool doesn't — it discovers topics automatically by analysing URL structure across all submitted domains. We extract meaningful tokens from URL paths (filtering structural noise like "blog", "page", "category"), then use bigram frequency analysis across the combined URL corpus to identify which topic clusters are most significant. The result is the actual topic landscape of your competitive set, not a topic you manually hypothesised.

A gap is a topic cluster where you have fewer than half the pages of the leading competitor AND that competitor has at least 5 pages on the topic. The 5-page threshold filters out accidental topic mentions. The 50% threshold captures meaningful underinvestment — if a competitor has 20 pages on "email automation" and you have 3, that's a gap worth addressing. Gaps are sorted by absolute page difference so the biggest opportunities surface first.

Whitespace is a topic cluster that exists in the URL landscape but has very few pages from any domain — typically 3 or fewer across all sites analysed. It represents an early-mover opportunity: a topic that's emerging or undervalued by the whole competitive set. Whitespace topics often correlate with rising search trends because no one has fully committed to them yet. Building coverage on whitespace topics now can establish authority before competition intensifies.

The tool is highly accurate for sites with descriptive URL slugs (most blogs, content marketing sites, documentation sites). It's less reliable for sites with parameter-based URLs (e.g., /page?id=123), numeric IDs in paths, or very short slugs. The bigram analysis also works better when analysing sites with 50+ indexed pages — smaller sites have too few URL signals to reliably identify clusters. If a domain returns very few topic clusters, it typically means that domain has non-descriptive URLs rather than limited content.

The Topical Authority Checker requires you to specify a topic (e.g., "email marketing") and returns a 0-100 score measuring how deeply you cover that specific topic. The Competitor Coverage Analyzer requires no topic input — it automatically discovers ALL topic clusters across all submitted domains and shows the full content strategy landscape. Use the Topical Authority Checker when you want to measure depth on a specific topic. Use this tool when you want to understand the full competitive content landscape without a hypothesis.

The current limit is 3 competitors plus your own domain (4 domains total). This keeps the analysis fast and the comparison matrix readable. For most content strategy work, comparing against your top 2-3 competitors is sufficient — adding more often introduces noise rather than signal.

No. The full analysis is free with no account required. There is a limit of 3 analyses per day per IP address.

If a domain has no discoverable sitemap (checked at /sitemap.xml, /sitemap_index.xml, and robots.txt), or the sitemap returns an error, that domain will be excluded from the cluster analysis with an error note. The analysis runs on whichever domains successfully returned sitemaps. You'll still get a useful comparison from the remaining domains.
