Verified site --PII REMOVED-- — Bing-specific >95% impressions collapse on 2026-05-16, no recovery; site fully healthy (Google unaffected), BWT Copilot won't open a case

Question

We are the verified owners of --PII REMOVED-- (owner: --PII REMOVED--; Bing Webmaster API key on file). We are reporting a sudden, sustained, Bing-specific collapse in search impressions and asking for a

human review — the Bing Webmaster Tools Copilot repeatedly declines to open a support case and deflects to "content quality," which our data contradicts.

The problem

Daily impressions dropped from ~1,160/day (stable through 2026-05-15) to 54 on 2026-05-16, then to single digits (3–33/day) for the 16+ days since, with no recovery. Clicks fell to ~0. A >95% overnight

drop on a single date.

Evidence the site is healthy (verified directly)

• Crawling is uninterrupted — Bingbot crawls 1,500–3,500 pages/day throughout.
  • Index is GROWING, not shrinking — InIndex 5,085 → 5,254. Pages are indexed; they are simply no longer served. This points to ranking/serving suppression, not a crawl/index failure.
  • Pages are fully indexable — fetching key URLs as Bingbot returns HTTP 200, <meta name="robots" content="index, follow"> (no noindex), correct self-referential canonical, and full hreflang.
  • robots.txt allows Bingbot (User-agent: * → Allow: /, no crawl-delay); sitemap index (4,619 URLs) returns 200.
  • GetCrawlIssues API is empty.
  • This is Bing-specific. Over the exact same window, our Google organic traffic (independent analytics) was stable and grew. A real content-quality regression would hit both engines — it did not.

  Anomalies in your data

• 2026-05-16 only: CrawlErrors spiked ~38 → 1,928 for one day, then normalized (150–400/day). Coincided with a brief 2-hour deploy window, fully resolved since.
  • GetUrlInfo returns HttpStatus=0 for URLs that externally return 200 and were recently crawled — appears to be a BWT reporting anomaly.
  • Monthly URL submission quota appears to have changed 4,000 → 3,000.

  Questions

  1. Was there a Bing algorithmic/quality update around 2026-05-15–16 that explains a >95% single-day impressions drop on a fully crawlable, indexable site?

1. Is there any manual/automated demotion on --PII REMOVED-- that does NOT surface via GetCrawlIssues? If so, what triggered it and how do we resolve it?
2. Why does GetUrlInfo report HttpStatus=0 for verified-200, recently-crawled URLs?
3. Was our monthly URL submission quota reduced (4,000 → 3,000)?
4. What concrete steps restore normal serving of our already-indexed pages?

Answer 1

Hi Никита Малофеев,

I really wish I could assist you directly on this issue. However, the behavior you're experiencing is tied to back‑end systems and service functionality, and unfortunately, we don't have the authority or access required to investigate or make changes at that level.

Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas.

Given these limitations, the most appropriate avenue for product changes or feature requests is to:

• Webmaster Support - Bing Webmaster Tools.
• Microsoft Support.

Please note that we and Copilot cannot make the request as your behavior or escalate your request.

Thank you for your understanding, and I hope the support team can resolve this for you soon.

Answer 2

Bing Webmaster Tools and the public Bing documentation do not expose internal ranking signals, manual actions, or per-site demotion details, and the provided context does not contain site- or date-specific information about algorithm updates or quota changes.

Within the available information, only the following supported actions and escalation paths apply:

1. For suspected ranking, quality, or safety interventions (algorithmic or manual), use the Bing “Report a concern” channel so a human reviewer can evaluate the case:
   • Submit the issue via the Bing Report a Concern form: https://www.microsoft.com/en-us/concern/bing
   • Clearly describe the sudden impressions drop, confirm that crawling and indexing are healthy, and that the issue is Bing-specific.
2. If there is concern that content has been removed or downranked due to quality, safety, or legal reasons, review Bing’s documented moderation and ranking principles to understand possible causes:
   • Bing may remove or downrank content based on spam signals, sensitive personal information, nonconsensual intimate imagery, exploitative removal practices, or legal demands.
   • Bing also applies additional algorithmic interventions when bad actors manipulate results or exploit “data voids,” and may downrank low-authority or potentially misleading content while still keeping it indexed.
3. If the site owner believes content removal or demotion is in error and has already addressed any potential policy issues, appeal via Bing Webmaster Tools:
   • Use Bing Webmaster Tools to request re-evaluation of removed or impacted content as described in the “appealing webpage content removal decisions” guidance.
4. For any objectionable or incorrect search behavior (including anomalies in how results are served), submit feedback directly from Bing:
   • Use the Feedback link at the bottom of Bing search results pages to report issues with how the site appears or is ranked.
5. For cached or outdated content issues, use the Bing Content Removal Tool (via Bing Webmaster Help & How-To) to request removal of outdated cached pages if that is contributing to incorrect serving behavior.

The context does not provide:

• Confirmation of any specific Bing algorithm update around 2026-05-15–16.
• Any documentation about per-site demotions that do not surface in GetCrawlIssues.
• Any explanation for GetUrlInfo returning HttpStatus=0.
• Any documented change in URL submission quotas from 4,000 to 3,000.

Given these limits, the only supported path to obtain a human review and any site-specific clarification is to:

• File a detailed report via the Bing Report a Concern form, and
• Use Bing Webmaster Tools’ appeal mechanism if there is suspicion of content removal or demotion.
