Technical SEO

lastmod

Also known as: sitemap modification date

Sitemap information about a significant resource change.

A practical example

After a price or content update, the page gets its actual modification date.

What should I know?

Don't change the date daily without changing content.

Technical SEO in practice

Check crawler access, server responses, and content processing separately. Then assess indexing and search appearance. These stages are connected but distinct and need different diagnostic methods.
