What it is for#
A sitemap lists the addresses you want Google to know about. It helps most on large sites, new sites, and pages with few links pointing at them.
What Google reads#
- Size: all formats limit one sitemap to 50MB uncompressed or 50,000 URLs.
- Google ignores the priority and changefreq values.
- Google uses lastmod if it is consistently and verifiably accurate, so only change it for a real update.
Common mistakes#
Listing redirected or noindex pages, and stamping every page with today's date.
Check it#
The site scan reads your sitemap and robots.txt and reports what is wrong with either.
Is our sitemap listing pages that redirect?
Yes, three. Each redirects to a page the sitemap already lists.
See it on your own site#
The free website check reads a site you name and reports what holds its pages back, with no account and no card. It changes nothing on your site.
