Quick Answer
Update and resubmit a sitemap for Bing after meaningful site changes, not on a fixed daily schedule. For most sites, that means 1 manual resubmission after a launch, migration, or major content update, then automatic updates in between. If your site is stable, a sitemap can sit for 2 to 8 weeks without manual resubmission; if you publish daily, fix URLs often, or launch big changes, treat resubmission as part of the release process, and if the site is complex, consult a professional and Bing’s documentation. Bing’s sitemap guidance and the Sitemap protocol both support that approach. (Source: Microsoft Bing Webmaster Guidelines, Sitemaps.org protocol)
I write about search and site indexing for a living, and the practical answer to How Often Should You Update and Resubmit a Sitemap for Bing? is simpler than most guides make it sound: Bing does not need you to spam resubmit on a schedule. It needs a clean, current XML file and a site that tells the same story through internal links, canonical tags, and server responses. On a stable site, one accurate file can do its job for weeks. On a fast-moving site, a daily generator is better than a weekly reminder.
Key takeaways
- Update the file when URLs are added, removed, redirected, or moved.
- Resubmit right after major changes, not every day out of habit.
- For small, steady sites, weekly or monthly checks are usually enough.
- For news, ecommerce, or heavily edited catalogs, automated refreshes make more sense.
- A sitemap does not override bad indexing signals such as noindex tags, blocked crawls, or broken canonicals.
- Bing’s sitemap files can include up to 50,000 URLs per file and 50 MB uncompressed. Microsoft Bing Webmaster Guidelines
How often should you update and resubmit a sitemap to Bing?
You should update the file as often as your important URLs change, and resubmit it when you want Bing to recrawl sooner. That usually means immediately after a launch, migration, redesign, bulk content update, or URL cleanup; for routine publishing, a daily or automatic update is better than a rigid calendar reminder.
The mistake I see most often is treating resubmission like a ritual. If you are unsure whether a specific setup needs a different cadence, consult a professional and check Bing’s guidance. Resubmission is not a ranking signal. It is a discovery nudge. Bing still decides what to crawl and index based on the page itself, the links pointing to it, and the technical signals around it.

A good rule is this:
- Small brochure site: update when content changes, then resubmit after meaningful edits or new sections.
- Content site publishing several times a week: update automatically or at least daily, resubmit after batches of new URLs.
- Ecommerce or marketplace: update every time inventory, category paths, or product URLs change materially.
- Migration or redesign: update immediately, then resubmit the new file after launch and again after crawl errors are fixed.
If your XML file includes only canonical, indexable URLs and matches live site architecture, Bing can usually find the rest without constant attention. If your file is stale, includes redirected URLs, or lists pages you no longer want indexed, resubmitting more often will not help; it may just repeat the confusion. Bing can also process large sites over time, so a delay of a few days is not unusual after major changes. (Source: Microsoft Bing Webmaster Tools)
What changes actually justify resubmitting?
Resubmit after any change that affects which URLs should be discovered or indexed. That includes new content, deleted URLs, 301 redirects, canonical changes, language variants, and major navigation shifts.
The most useful trigger is not “I posted something.” It is “the set of URLs Bing should trust has changed.” That distinction matters because a fresh post hidden behind a poor internal link structure may still crawl slowly, while a well-linked update can be found without manual intervention.
I would resubmit immediately in these cases:
- A site migration from one domain to another
- HTTPS changes
- URL structure changes, such as
/blog/post-name/becoming/resources/post-name/ - Mass content pruning
- Product feed or catalog changes that affect hundreds of URLs
- Adding hreflang or fixing it after a deployment
- Fixing broken canonical tags or indexation mistakes
I would not rush to resubmit for trivial edits such as a typo fix, a swapped headline, or a single image replacement. Bing will usually pick those up through recrawl, and that is exactly the kind of low-value churn that turns site owners into dashboard watchers.
One more practical point: if the file is generated dynamically, make sure it reflects the live site within minutes or hours, not days. A sitemap that lags behind the CMS defeats its own purpose.
When does a sitemap update matter more than a manual resubmit?
The sitemap update matters more when Bing can already crawl the site and the file simply needs to stay accurate. Manual resubmission matters more when you have fresh URLs Bing has not yet seen, or when the site’s structure changed enough that you do not want to wait for normal discovery.
That is the real split.
If your site is well-linked and small, Bing will often find new URLs from normal crawling, internal links, and external links. In that case, the file is supporting evidence. It helps Bing confirm site structure, not replace crawl discovery.
If your site is large, new URLs are buried, or crawl budget is tight, then an updated file plus resubmission can shorten the delay. This is especially useful for:
- Large ecommerce catalogs with faceted navigation
- Publisher sites with many archives
- International sites using hreflang
- Newly launched sections with few internal links
- Sites recovering from a migration or outage
The catch is that resubmission cannot repair a weak technical foundation. If a URL returns 404, 410, 302 loops, or noindex, Bing may still ignore it. If the canonical points somewhere else, Bing may follow that instead. If robots.txt blocks crawling, the file alone does not override the block.
For that reason, I treat resubmission as a follow-up step, not a substitute for checking:
- HTTP status codes
- Canonical tags
- Robots rules
- Internal links
- Redirect chains
If you are working through those items on a complex site, consult a professional before changing cadence or making assumptions about indexing timing.
The difference between automatic updates and manual resubmission
Automatic updates win for sites that change often. Manual resubmission wins for important one-off changes. A good setup usually uses both.
An automatic XML file generator keeps Bing from seeing stale URLs. That is the baseline. If your CMS, plugin, or build system can regenerate the file on publish, on delete, and on redirect changes, you should want that. It reduces human error and keeps the file aligned with the live site. For example, a daily-news site that publishes 20 to 200 URLs a day benefits more from automation than from hand submissions. Sitemaps.org protocol
Manual resubmission is the alert button. Use it when the change is too important to leave to the next crawl cycle. A launch, a migration, or a large content refresh deserves that extra push.
Here is a simple way to think about it:
| Criteria | Automatic updates | Manual resubmission | Winner for this condition |
|---|---|---|---|
| Frequency of change | Best for daily or hourly changes | Best for occasional major changes | Automatic for fast-moving sites |
| Human effort | Low once configured | Requires an active step | Automatic for lean teams |
| Speed after launch | Depends on crawl timing | Can accelerate discovery | Manual after critical launches |
| Error risk | Lower if tied to the CMS | Higher if someone forgets | Automatic for consistency |
| Best use case | Catalogs, blogs, newsrooms | Migrations, fixes, major releases | Depends on the event |
| Need for monitoring | Still needs spot checks | Needs a checklist every time | Automatic for scale |
| Handling deletions and redirects | Can keep the file current faster | Only helps if you remember to act | Automatic for site hygiene |
| Value after technical fixes | Good if the file regenerates cleanly | Useful to nudge recrawl | Manual after fixes |
If you want the shortest honest answer, it is this: set up automatic updates, then use manual resubmission only for meaningful changes. That combination avoids both neglect and busywork.
How often is too often?
Daily manual resubmission is usually too often unless you run a news operation, a high-churn catalog, or a dev team making repeated release fixes. For most sites, that pattern becomes noise.
There is no public rule that says Bing punishes frequent resubmission, but frequency alone does not create value. If the underlying URLs have not changed, resubmitting every morning is mostly an admin habit. The time is better spent on crawl errors, index coverage, and internal links.
A better rhythm is tied to change:
- After launch: resubmit once
- After fixing crawl blockers: resubmit once
- After bulk content additions: resubmit once
- After redirect or canonical cleanup: resubmit once
- During normal publishing: let the file update automatically
For a stable site, checking the file monthly is usually enough. For a busy site, I would inspect it weekly. For a site in transition, daily validation may be warranted for a short period, but only while the issue is active. If you are unsure whether your cadence is excessive, consult a professional and compare it with Bing’s crawl and indexing data.
One caution: if Bing Webmaster Tools shows no indexing response after a reasonable wait, do not keep pressing submit. Look for technical blockers instead. A resubmission button is not a troubleshooting strategy.
When should you stop worrying about it?
You should stop worrying about manual resubmission once the file is accurate, the site is crawlable, and Bing is already discovering new content at a healthy pace. At that point, the sitemap is doing its job quietly.
That usually means:
- New URLs appear in Bing index reports without delay that matters to you
- Old URLs disappear after redirects or removals
- Canonicals are consistent
- Robots rules are intentional
- The XML file matches live indexable URLs
If those conditions are in place, resubmitting more often will not produce much. The real work moves elsewhere: information architecture, link equity, content quality, and server reliability.
This is also where many site owners overreact to lag. Indexing is not instant. A valid URL can take time to be crawled, processed, and reflected in search. A one-off delay does not automatically mean your file is stale. Bing’s documentation on sitemap submission and crawl discovery is the better reference point than folklore.

Exception scenarios that change the answer
The general rule flips in a few situations. If one of these is true, I would update and resubmit faster than usual.
-
You just migrated domains or changed URL structure.
In that case, resubmit immediately and monitor crawl errors for at least the first few days. A migration creates enough change that waiting is foolish. -
You run news, jobs, or inventory that changes by the hour.
Here, automatic generation is the right default, and resubmission after major feed refreshes or sitewide updates can help Bing catch the new state sooner. -
Your site has a history of crawl problems.
If Bing has been missing URLs because of bad canonicals, blocked folders, or weak internal linking, a fresh file is not enough. Fix the cause, then resubmit once the fix is live. -
You removed a large number of URLs.
After pruning content, update the file quickly so Bing sees the cleaner structure and can stop wasting time on dead or redirected addresses.
These are the situations where I would be more aggressive. Outside them, restraint is usually smarter.
The verdict: how often should you update and resubmit?
Update the file automatically whenever your indexable URLs change. Resubmit it after major changes, after launches, after migrations, and after technical fixes that affect crawl or indexation. If your site is stable, a monthly check is enough; if it changes often, daily regeneration is better than repeated manual submissions. I would not make manual resubmission a routine unless the site is large, fast-moving, or in recovery.
Choose automatic updating if you publish often, manage many URLs, or want fewer mistakes. Choose manual resubmission if you have occasional major releases and need Bing to notice them quickly. Neither if your file is stale, your pages are blocked, or your redirects and canonicals are wrong; in that case, the problem is not timing, it is site hygiene.
FAQ
Does Bing need a sitemap to index a site?
No. Bing can crawl and index without it, but a clean XML file helps discovery, especially on large or deeply linked sites.
How long should I wait after resubmitting?
Wait long enough for a normal crawl cycle to happen. That is site-dependent, so I would look for changes over days rather than minutes.
Should I include every URL I have ever published?
No. Only include canonical, indexable URLs that return a successful status and reflect the current site structure.
Can I resubmit the same sitemap after every small edit?
You can, but I would not. Small edits rarely justify the extra attention unless they affect discoverability or indexation.
Does resubmitting improve rankings?
No. Resubmission helps discovery and refresh, not ranking by itself.
