See how changefreq and priority values are spread across a sitemap.
How to use the Sitemap frequency analyzer
- Enter a sitemap URL.
- Review the distributions.
- Clean up values that don't reflect reality, or drop them.
Do these tags matter?
Google ignores changefreq and priority. They are harmless, but an accurate lastmod is the field worth keeping right.
Reading the two charts
The changefreq chart counts how many URLs use each value (daily, weekly, monthly and so on), and the priority chart counts each value from 1.0 down to 0.0. "(unset)" means the tag is missing, which is fine. A sitemap where every URL says daily and 1.0 tells you the values are a plugin default, not a real signal. A spread that matches the site, such as home page at 1.0, product pages at 0.8 and old posts at 0.3, shows someone set them on purpose, which can still be useful for Bing and smaller engines.
What to do with them
If the values are defaults, either remove both tags or set them per page type. Spend the effort on lastmod instead: make it change only when the main content of a page changes. Watch for invalid values; anything outside 0.0–1.0 or a changefreq like "often" breaks validation, and the sitemap validator will list them.
