What is a Sitemap Generator?

A Sitemap Generator is a free online tool that creates an XML sitemap for your website. An XML sitemap is a structured file that lists all the important URLs on your site, along with metadata like last modification date, change frequency, and priority. It helps search engines discover, crawl, and index your pages more efficiently — a critical component of technical SEO.

Why do you need a sitemap?

Search engines discover pages by following links, but they can miss pages that are not well-linked internally. A sitemap ensures every important page is discoverable, tells search engines which pages were recently updated (prompting re-crawling), and indicates the relative importance of different pages. Sites with good sitemaps get indexed faster and more completely than those without.

How to create an XML sitemap?

Enter your website URLs along with optional metadata: lastmod (when the page was last updated), changefreq (how often it changes — daily, weekly, monthly), and priority (relative importance from 0.0 to 1.0, with your homepage typically at 1.0). The generator creates a properly formatted XML sitemap that you can download and upload to your root directory. Submit it to Google via Search Console for best results.
