Free Sitemap Frequency Analyzer

Our sitemap frequency analyzer fetches a sitemap (recursing into a sitemap index when it finds one), groups every URL by its first path segment (/blog/, /docs/, /products/), and recommends a changefreq value per group based on the median age of the lastmod values within. We use standard sitemaps.org changefreq tokens: hourly, daily, weekly, monthly, yearly. Prefixes with fewer than three dated URLs get a "needs more data" verdict instead of a guess.

The recommendation logic is conservative. We use the median age, not the average, so one outlier does not swing the call. If the freshest URL in a prefix is itself over a year old, the recommendation downgrades to yearly even when the median looks fresh, because a "weekly" recommendation on a folder nobody touches is misleading.

For SEOs

Our tool turns lastmod observations into a usable config, so you can:

• Set realistic changefreq values that match how your content actually changes
• Spot prefixes where your team claims weekly updates but lastmod shows yearly
• Hand a CSV to a developer to drive the next sitemap regeneration

For Developers

Our tool saves you writing the cadence-analysis script, so you can:

• Generate a per-prefix changefreq mapping ready to feed into your sitemap builder
• Audit an existing sitemap's changefreq values against what lastmod implies
• Identify dead sections that should drop out of the sitemap entirely

Why Use Our Sitemap Frequency Analyzer

• Honest, not hand-wavy: Prefixes with fewer than three dated URLs return "needs more data". We never invent a cadence.
• Median over mean: One stale or one fresh outlier will not flip the recommendation.
• CSV export: Copy or download the per-prefix table, ready to drive your next sitemap build.
