The short version
Changefreq is an optional XML sitemap tag that was designed to hint how often a page changes. For modern Google SEO, it is not a ranking lever. Google’s sitemap documentation says it ignores changefreq and priority values, while lastmod can be used if it is accurate and verifiable.
01
What changefreq means
In an XML sitemap, changefreq can say a URL changes hourly, daily, weekly, monthly, yearly, or never. The problem is that this hint is easy to fake and often inaccurate. Search engines have better crawl signals, including real page changes, internal links, server responses, and historical crawl patterns.
That is why obsessing over changefreq usually wastes time. If your site has crawl or indexing problems, the cause is rarely the changefreq value.
02
What Google actually says
Google’s current sitemap documentation says Google ignores priority and changefreq values. It may use lastmod when the value is consistently accurate and reflects a significant update to the page, structured data, or links.
The practical takeaway: keep sitemaps clean, include canonical indexable URLs, and make lastmod honest. Do not update lastmod just because the footer year changed.
03
What to fix instead
If you want better crawl and indexation, focus on the signals search engines actually use. Make important pages internally linked, indexable, canonical, fast enough, useful, and included in a clean sitemap. Remove or noindex low-value duplicates where appropriate.
- Submit only canonical, indexable URLs.
- Keep lastmod accurate for meaningful content changes.
- Fix broken links and redirect chains.
- Strengthen internal links to important pages.
- Use Search Console indexing reports to validate discovery.

Frequently asked questions
Does changefreq help SEO?
For Google, changefreq is ignored and should not be treated as an SEO ranking or crawl-priority lever.

You can leave it or remove it, but do not rely on it. Accurate canonical URLs and lastmod values matter more.
What is lastmod?
Lastmod is a sitemap value that tells search engines when a page was significantly updated.
Can a bad sitemap hurt indexation?
