How it works & useful details

How this tool works

Enter one HTTP(S) URL per line, optionally followed by a tab and YYYY-MM-DD lastmod date. A per-page date overrides the optional default. All URLs must use the same protocol, host and port; host the file at that origin root. Duplicate removal retains the first normalized URL and its date. Fragments can be removed explicitly. Up to 200 lines and 200,000 input characters; normalized URLs must be shorter than 2,048 characters. No crawling, cross-site sitemaps or sitemap indexes. Optional hints do not guarantee indexing.
