What is XML Sitemap Generator – Changefreq, Priority & Lastmod?

Search engines discover pages more reliably when you provide a sitemap.xml. This generator lets you paste a list of URLs, set optional changefreq (always / hourly / daily / weekly / monthly / yearly / never), priority (0.0–1.0), and lastmod dates, then download a valid XML file — all without uploading your URL list to any server.
