Search engines crawl faster and more completely when you hand them a sitemap instead of making them discover every page on their own. The Sitemap Generator turns a plain list of URLs into a valid sitemap.xml file in seconds.
What Is the Sitemap Generator?
Sitemap Generator is one of the tools in WebdevToolbox’s Generators category. It generates an XML sitemap from a list of URLs for better search engine indexing, following the sitemaps.org protocol used by Google, Bing, and other crawlers.
How to Use It
- Open the tool at /tools/sitemap-generator.
- Paste one URL per line into the input box.
- Set global defaults for priority, change frequency, and last modified date.
- Optionally override any of those per line using
url|priority|changefreq|lastmodsyntax — trailing parts you skip fall back to the shared defaults. - Toggle which XML fields (priority, changefreq, lastmod) should be included in the output.
- Copy or download the generated
sitemap.xml, plus the matchingSitemap:line to add to yourrobots.txt.
Key Features
- Per-URL overrides — mix a global default with page-specific priority or update frequency where it matters.
- Optional fields — leave out
<priority>,<changefreq>, or<lastmod>entirely if your site doesn’t need them. - robots.txt reference line — generated automatically so search engines can find your sitemap without manual submission.
- Instant validation — malformed or empty lines are skipped automatically.
When to Use the Sitemap Generator
- Launching a new site — give search engines a complete list of pages to index from day one.
- Static site generators without built-in sitemaps — quickly produce one without adding a build plugin.
- Bulk URL updates — regenerate a sitemap after restructuring URLs or adding new content in bulk.
