Common questions
Do I need changefreq and priority?
No, both are optional hints, and Google has said for years it largely ignores priority and treats changefreq loosely at best. Include them if another crawler you care about uses them, otherwise a plain URL list with lastmod is perfectly valid.
What counts as a valid URL here?
Any line that parses as a full http:// or https:// URL. Relative paths or lines missing the protocol are skipped and called out in the result message so you know what got left out.
Is there a limit to how many URLs I can add?
The sitemap protocol caps a single file at 50,000 URLs, this tool doesn't enforce that limit itself, but if you're near it, consider splitting into multiple sitemap files with a sitemap index.
