A complete guide to submitting your XML sitemap to Bing Webmaster Tools, ensuring your content is discoverable by Bing search and ChatGPT's AI-powered search engine.

Bing Webmaster Tools is Microsoft's free platform for website owners to monitor and optimise their site's presence in Bing search results. More importantly, Bing now powers ChatGPT's search functionality, meaning your sitemap submission directly impacts whether AI-powered search engines can discover and cite your content.
An XML sitemap is a file that lists all the important pages on your website, helping search engines understand your site structure and find content efficiently. While search engines can discover pages through links, submitting a sitemap ensures faster, more complete indexing — particularly for new sites, large sites, or content that isn't heavily linked.
According to Microsoft's own guidance, sitemaps are especially valuable for keeping content discoverable in AI-powered search environments, where traditional crawling patterns may not capture all relevant pages.
Bing processes over 12 billion searches per month globally and holds approximately 3% of the UK search market. But the real strategic value lies in its integration with AI platforms:
For organisations focused on generative engine optimisation (GEO), Bing Webmaster Tools is not optional — it's foundational infrastructure.
Before you can submit a sitemap, you must verify ownership of your website in Bing Webmaster Tools. There are three verification methods:
https://yoursite.com/BingSiteAuth.xml)<head> section of your homepage HTMLIf your site is already verified in Google Search Console, you can import it directly into Bing Webmaster Tools using your Google account credentials. This is the fastest method if you're already using Google Search Console.
Once your site is verified, follow these steps to submit your XML sitemap:
Your sitemap is typically located at one of these URLs:
https://yoursite.com/sitemap.xmlhttps://yoursite.com/sitemap_index.xmlhttps://yoursite.com/wp-sitemap.xml (WordPress sites)If you're using a CMS like WordPress, Webflow, or Shopify, your sitemap is usually generated automatically. Check your SEO plugin settings (e.g., Yoast, Rank Math, All in One SEO) or your platform's documentation to confirm the exact URL.
https://yoursite.com/sitemap.xml)Bing will immediately begin processing your sitemap. You'll see a confirmation message, and the sitemap will appear in your Sitemaps dashboard with a status indicator.
After submission, Bing Webmaster Tools provides several diagnostic views:
Check back within 24–48 hours to see initial indexing results. Large sitemaps may take longer to process fully.
Bing Webmaster Tools accepts the following sitemap formats:
For most websites, an XML sitemap is the best choice. It supports additional metadata like last modified date, change frequency, and priority, which help search engines prioritise crawling.
You don't need to manually resubmit your sitemap every time you publish new content. Once submitted, Bing will periodically re-crawl your sitemap to discover updates. However, you should:
For high-frequency publishing (e.g., news sites, blogs), consider using Bing's URL Submission API to push new URLs immediately rather than waiting for the next sitemap crawl.
Cause: The sitemap URL returns a 404 error, or the file is not accessible.
Fix: Verify the sitemap URL in your browser. Ensure it's publicly accessible and not blocked by robots.txt or authentication.
Cause: The sitemap includes URLs from a different domain or subdomain.
Fix: Sitemaps must only contain URLs from the verified domain. If you have multiple subdomains, verify and submit sitemaps for each separately.
Cause: Bing limits sitemaps to 50,000 URLs or 50MB (uncompressed).
Fix: Split your sitemap into multiple files and create a sitemap index file that references them.
Cause: Your robots.txt file disallows crawling of URLs listed in the sitemap.
Fix: Review your robots.txt file and remove disallow rules for URLs you want indexed, or remove those URLs from your sitemap.
If you prefer not to use the Bing Webmaster Tools interface, you can submit your sitemap via:
Add this line to your robots.txt file:
Sitemap: https://yoursite.com/sitemap.xml
Bing will automatically discover and process the sitemap when it crawls your robots.txt file.
Bing offers an API for programmatic sitemap and URL submission. This is useful for developers automating indexing workflows. Full documentation is available in the Bing Webmaster API reference.
