Example

After launching a 40-page Webflow site, an XML sitemap is submitted to Google Search Console to accelerate indexing of all pages.

Submitting an XML sitemap to Google Search Console can increase the number of indexed pages by up to 45% for large sites — helping ensure content that may not be easily discoverable through internal links gets crawled and ranked.

XML sitemap, Site index

What it applies to

Every website — but it is especially valuable for new sites (where Google hasn't yet crawled all pages), large sites (where crawl budget needs to be directed efficiently), and sites with pages not well-linked internally.

How to create and submit a sitemap

  • Most CMS platforms and website builders generate an XML sitemap automatically. In Webflow, the sitemap is automatically generated and available at yourdomain.com/sitemap.xml.
  • For custom-built sites, generate a sitemap using a tool like Screaming Frog or the XML Sitemap Generator plugin (WordPress), or build one programmatically.
  • Ensure the sitemap includes only indexable pages — exclude noindex pages, paginated duplicates, and URL parameter variants.
  • Submit to Google: Google Search Console → Sitemaps → enter your sitemap URL → Submit.
  • Submit to Bing: Bing Webmaster Tools → Sitemaps → submit URL.

Sitemap best practices

  • Keep the sitemap updated automatically — it should reflect the current state of published content at all times.
  • Split large sitemaps (50,000+ URLs) into multiple files with a sitemap index file referencing each.
  • Include the sitemap URL in your robots.txt: Sitemap: https://yourdomain.com/sitemap.xml
