Sitemap analyzer. See how any site is built — and how fast it ships.

It reads any website’s XML sitemap and turns it into two views. First, the site structure: every URL grouped by its top-level section — /blog, /docs, /products — so you can see where a site concentrates its pages. Second, the publishing cadence: how many URLs were last modified in each recent month, so you can see how often a site actually ships content and whether that pace is rising or falling.

We first read the site’s robots.txt and follow any Sitemap: directives it declares. If none are declared, we probe the conventional locations — /sitemap.xml, /sitemap_index.xml, /wp-sitemap.xml and a few others. When we find a sitemap index, we walk its child sitemaps automatically and combine every page URL into one analysis.

Every URL in a sitemap can carry a <lastmod> date — the day that page last changed. We bucket those dates by month and count them, which gives a month-by-month histogram of how much a site published or updated. The headline rate is the average over the last twelve months; the trend compares the last three months against the three before them.

Cadence is only as good as the dates a site emits. If most URLs have no lastmod, we tell you — and that gap is itself worth fixing.

Content compounds. A competitor quietly shipping twenty pages a month is building topical coverage — and the AI-answer presence that follows it — far faster than one shipping two. Reading their sitemap tells you the sections they are investing in and the pace you would need to match or beat, without guessing.

Yes, up to a point. We walk sitemap indexes and their children, but cap the analysis at a large sample of URLs so results come back quickly. On very large sites the numbers are a representative sample rather than the full index — we flag it in the result when that happens. Gzipped sitemaps (.xml.gz) are not read yet.

Yes. No signup, no email gate, no credit card. It reads public sitemap data, so there is nothing to unlock. We built it because structure and cadence are exactly the signals Roman acts on — most tools stop at showing you the gap; Roman’s agents research, write and publish the content that closes it.
