URLs, or a sitemap to check
One URL per line, optionally followed by a pipe and a
lastmod. Or paste an existing sitemap.xml — or a sitemap index — and it
will be checked instead of built.
sitemap.xml
No <priority> and no <changefreq>, and
that is deliberate: Google ignores both. A priority of 0.8 on every URL — which is what most
generators emit — would express nothing even if it were read.
The sitemap index
Each URL
Built and checked in this browser — nothing is uploaded and no URL is fetched, so this checks the list you
give it rather than whether those pages exist. Google ignores
<priority> and <changefreq>. It does read
<lastmod> — but only while it is believed, so an absent lastmod is better than one that
says every page changed today. And a sitemap asks a crawler to look; it does not get a page indexed, and
leaving a page out does not keep it out.
The Sitemap Generator needs JavaScript: the XML is built and parsed in this browser. With JavaScript switched off there is nothing to do the work.
