Key Takeaways
- Bing needs a reachable URL, not an emailed, uploaded, or pasted file.
- In Bing Webmaster Tools, verify ownership, then submit the sitemap URL in Sitemaps.
- Keep feed URLs public, stable, and matched to canonical pages.
- For sitemap indexes, submit the index file and let Bing find the child sitemaps.
If you need how to submit sitemap to Bing, the fastest route is to add your site in Bing Webmaster Tools, verify ownership, and submit the sitemap URL; the same workflow works for XML sitemaps, RSS feeds used as feed-style sitemaps, and sitemap index files. Bing says it supports sitemap submission in Webmaster Tools, and its sitemap protocol documentation uses the standard 50,000-URL and 50 MB uncompressed limits for a single sitemap file.

What Bing actually needs from your sitemap
Bing needs a URL it can fetch, not a file you emailed, uploaded, or pasted into chat. If the sitemap is XML, RSS, or a sitemap index, the rule is the same: Bing must be able to request the file over HTTPS or HTTP and get a clean 200 response, not a login wall, 403, 404, or a redirect chain that goes three hops deep.
That sounds simple, but it changes the whole approach. If your site is small and has one sitemap under 50 MB uncompressed with fewer than 50,000 URLs, submit that file directly. If your site is larger, split it and submit a sitemap index file instead. If your publishing platform emits an RSS or Atom feed, Bing can read that too, but consult a professional or check Bing’s current documentation before using it as a substitute for a sitemap on anything beyond a narrowly feed-driven site.
The practical question is not “Which format is best?” It is “Which format matches the way my site already publishes URLs?” A WordPress site with Yoast or Rank Math usually has an XML sitemap already. A news site may have a feed plus separate XML sitemaps. A large ecommerce catalog often needs a sitemap index because the URL count climbs fast.
Here is the simplest way to think about it:
| Situation | Best Path | Why Other Options Fail |
|---|---|---|
| One small site, one XML sitemap | Submit the XML file directly | A sitemap index adds extra complexity you do not need |
| Large site with many sitemap files | Submit the sitemap index file | Submitting every child sitemap separately is clutter |
| Fresh content driven by posts or items | Submit RSS/Atom feed if Bing supports it in your workflow | A feed is not a full replacement for all canonical URLs |
| Mixed old and new URLs | Submit XML sitemap plus update the index as files change | Relying on a feed misses deeper pages |
Quick check: if you can explain your site in one sentence, you probably know whether a single sitemap or an index file fits.
How do I submit a sitemap to Bing?
You submit a sitemap to Bing in Bing Webmaster Tools by adding your site, verifying ownership, then entering the sitemap URL in the Sitemaps area. That is the normal path for XML sitemap files and sitemap index files, and it is the cleanest way to get Bing’s crawler pointed at the right URLs.
If your site is not already in Bing Webmaster Tools, start there. The process is built around ownership verification, and Bing offers methods such as XML file upload, DNS record, or meta tag verification depending on the interface. Once verified, submit the sitemap URL under the site’s Sitemaps section. Microsoft’s own Bing Webmaster Tools documentation also explains the site-add and verification flow.

Use this path if:
- your sitemap lives at a public URL like
https://example.com/sitemap.xml - your sitemap index lives at something like
https://example.com/sitemap_index.xml - your site has more than a handful of pages and you want Bing to crawl with less guesswork
Use a Bing API only if you already have a technical workflow for indexing and you are maintaining URLs at scale. For most site owners, the API is not the first move. The first move is still the URL submission inside Webmaster Tools.
- Sign in to Bing Webmaster Tools with a Microsoft account.
- Add your website as a new property.
- Verify ownership using one of Bing’s offered methods.
- Open the Sitemaps section for that site.
- Paste the full sitemap URL, such as
/sitemap.xmlor/sitemap_index.xml. - Submit and wait for Bing to show a status such as queued, success, or error.
- If Bing reports an issue, open the sitemap URL in a browser and fix the HTTP status, robots blocking, or XML error before resubmitting.
A common mistake is submitting the homepage or a directory instead of the actual sitemap file. Bing needs the file itself, not the folder it sits in. Another mistake is submitting a sitemap URL that redirects to a blocked location or to a URL with query parameters that change every visit.
Quick check: if you can open the sitemap URL in an incognito browser window and see XML, you are ready to submit it.
Which file type should I submit: XML, RSS, or sitemap index?
The sitemap index file is the right choice when you have multiple sitemap files, while a single XML sitemap is best when your site is small enough to fit cleanly in one file. RSS is useful when you publish a feed of recent content, but it should stay a supplement unless the feed truly covers the content you want Bing to discover.
Here is the basic split:
- XML sitemap: best for full site coverage. It can list canonical URLs, images, video metadata, and lastmod information.
- Sitemap index: best when you have many XML sitemap files. It points Bing to child sitemaps.
- RSS/Atom feed: best for recent updates and frequently published items, especially if your CMS already creates one.
A sitemap index is not a different kind of content map so much as a pointer file. It lists other sitemaps. If your site has 120,000 URLs, for example, a single XML sitemap will not fit because the common standard limits one sitemap to 50,000 URLs and 50 MB uncompressed. That is when an index file becomes the right answer, not an optional extra.
If you are running a blog, XML plus RSS is a sensible pairing. If you run ecommerce, XML plus sitemap index is the safer default. If you run a tiny brochure site with 12 pages, a single XML sitemap is enough and the extra layers are overkill.
- Count your URLs roughly, not perfectly, before choosing a format.
- If the site is under 50,000 URLs and under 50 MB uncompressed, keep one XML sitemap if it stays readable.
- If it exceeds either limit, split it into multiple XML sitemaps.
- Create a sitemap index file that lists those child sitemaps.
- Submit the index file to Bing, not each child file unless Bing specifically prompts you to inspect them.
- If you publish a feed, submit that too only as a secondary discovery path.
Quick check: if your site has more than one content type or a large archive, the index file is probably the better fit.
How to submit RSS and Atom feeds to Bing
You submit RSS or Atom feeds the same way you submit any sitemap URL: add the feed URL in Bing Webmaster Tools if Bing accepts it in your setup, or expose the feed cleanly so Bing can crawl it as a discovery source. The key is that the feed must be stable, public, and tied to canonical URLs.
This matters because feeds solve a narrow problem. They are excellent for new posts, new products, and recent updates. They are not a full inventory of your site unless your entire site really does live in the feed. If the feed only shows the latest 20 items, then that feed is a short-term signal, not complete coverage.
Use RSS or Atom when:
- your CMS automatically maintains a feed
- you care most about new content being found quickly
- your feed entries contain the canonical URL, not a tracking URL or session URL
Do not rely on RSS alone if:
- your site has deep archives
- important pages are not in the feed
- you need Bing to understand your whole site structure
For WordPress, the default feed URLs are often predictable, but the exact path depends on the setup. For custom builds, check the feed endpoint in a browser and make sure it returns valid XML. If it is malformed, Bing may ignore it or parse only part of it. XML validity matters more than clever format choices.
- Open your site’s RSS or Atom feed in a browser.
- Confirm it returns XML and not an HTML error page.
- Check that each item points to the canonical page URL.
- Remove tracking parameters from feed links if possible.
- Submit the feed URL in Bing Webmaster Tools if your interface allows it.
- Keep the feed updated whenever you publish new content.
A feed is often enough for a news blog, but it is not a safe only method for any site that sells, catalogs, or archives. Quick check: if your feed only shows your last few posts, you still need an XML sitemap. For related setup guidance, see How to submit URLs to Bing and XML sitemap best practices.
If your site uses a sitemap index, do this instead
If your site uses a sitemap index, submit the index file and let Bing discover the child sitemaps from there. That is the correct move for large sites, multilingual sites, and any site that generates separate sitemaps for posts, pages, products, or media.
A sitemap index usually looks like a plain XML file with <sitemap> entries pointing to other sitemap files. Bing does not need you to submit each child separately if the index is reachable and valid. That saves time and makes maintenance easier when one child sitemap changes every day.
Use this path if:
- you have more than one sitemap file
- your CMS creates separate sitemap sections automatically
- you expect the URL list to grow, shrink, or rotate often
What breaks this setup is not complexity. It is bad plumbing. If the index references a child file that returns 404, Bing will hit a dead end. If the child sitemap contains blocked URLs, noindex pages, or canonical conflicts, the index still submits, but the crawl quality suffers.
Here is the cleaner workflow:
- Open the sitemap index URL in a browser and confirm it loads as XML.
- Open each child sitemap listed in the index and confirm it also loads.
- Check that the URLs inside each child file are canonical and public.
- Verify the index does not point to redirected or expired sitemap URLs.
- Submit only the index file in Bing Webmaster Tools.
- Fix any broken child files, then resubmit the index if needed.
This approach is wrong for a tiny site with one sitemap and no growth plans. There, a sitemap index is just extra moving parts. Quick check: if your sitemap file names include sections like posts, pages, and products, submit the index.
The edge cases that break the normal advice
The normal advice breaks down when Bing can fetch the sitemap but still cannot use it cleanly. That is when you need to change the file, not just resubmit it.
Here are the cases that matter most:
-
Your sitemap URL redirects several times.
What changes: Bing may reach the file, but the chain wastes crawl effort.
What to do instead: point Bing to the final URL directly and keep redirects to one hop or none. -
Your sitemap is blocked by robots.txt or returns 403 to bots.
What changes: Bing sees the door but not the room.
What to do instead: allow the sitemap URL itself, even if you block some page paths separately. -
Your XML contains URLs that redirect, 404, or canonicalize elsewhere.
What changes: the sitemap becomes a noisy signal.
What to do instead: list only final, indexable canonical URLs. -
Your feed only shows recent items.
What changes: Bing can discover new content, but not your full site.
What to do instead: submit XML as the main sitemap and keep the feed as a supplement. -
Your site is multilingual and uses hreflang.
What changes: the sitemap needs proper language alternates, not separate guessing.
What to do instead: make sure the XML sitemap format includes the alternate language URLs correctly and that each version is live. -
Your site is enormous and changes daily.
What changes: manual resubmission becomes pointless.
What to do instead: use a sitemap index, keep child files split by section or update cadence, and automate regeneration.
The big trap is thinking submission alone fixes indexing. It does not. Submission only gives Bing the map. The map still has to match reality. Quick check: if your sitemap contains URLs you would not want a user to bookmark, clean it before you submit it.
A practical submission checklist for Bing
If you want the shortest path to a clean submission, verify the file, choose the right format, and avoid telling Bing about junk URLs. That order saves the most time.
Use this checklist:
- Open the sitemap, feed, or sitemap index URL directly in a browser.
- Confirm it returns XML, not HTML or an error page.
- Check that the file is public and not blocked by login, robots rules, or firewall rules.
- Choose one primary submission: XML for small sites, sitemap index for larger ones, RSS only as a supplement.
- Submit the URL in Bing Webmaster Tools after verifying ownership.
- Inspect Bing’s status and fix any crawl or parse errors before submitting again.
- Keep the file current when URLs are added, removed, or canonicalized.
The standard advice is wrong if it tells you to submit every possible file and hope Bing sorts it out. It will not. One clean sitemap index plus a good XML structure beats five mismatched files every time.
Quick check: if your sitemap file names and your live site structure look like twins, you are doing it right.
FAQ
Can I submit more than one sitemap to Bing?
Yes. Bing can accept multiple sitemap URLs, and a sitemap index is the preferred way to group them when the site has many files.
Does Bing require RSS instead of XML?
No. XML sitemaps remain the main format for broad coverage, while RSS or Atom is optional as a supplement for recent content.
How long does Bing take to process a sitemap?
Processing can happen quickly, but crawl and indexing timing varies by site size, update frequency, and crawl demand.
Should I resubmit after every site update?
No. Resubmit only when the sitemap file itself changes materially or Bing reports an error.
