Bing is not indexing your site, and it matters more than you think
You have never registered with Bing, or you have and it sends nothing, and it feels too small to be worth the hour.
It is not too small to matter
On this site, one non-Google engine delivered roughly a fifth of Google's clicks in its best month. That is not a rounding error, it is a fifth of a channel, and it required no additional content.
It can go to zero silently
This site recorded 31 consecutive days of exactly zero clicks from one engine, 17 May to 16 June. Nothing had been deployed. No warning was sent. A blended traffic total hid it completely, because the other engine was having its best month at the same time.
Escalate cheapest first
Open the engine's console. Resubmit the sitemap and request a recrawl. Only then look at infrastructure, and only after that at content. Shipping a large content fix and a resubmit together is how the cheap action gets no credit and the expensive one enters your playbook forever.
Bing goes silent in ways Google does not
This site logged exactly 31 consecutive days, 17 May to 16 June, with zero clicks from Bing. No penalty, no message, no change on our side, and no explanation when it came back. If you are watching a Bing number go flat, the most likely explanation is that Bing is doing this to you, not that you did something.
What to do during a blackout
Verify the site in Bing Webmaster Tools, submit the sitemap, confirm IndexNow is firing if you use it, and then stop. There is no lever. The productive response is to make sure the blackout is visible in your own reporting so you do not misread the total as a Google problem and go rewrite pages that were working fine.
Measured, not asserted
Recovery came from a reindex request, not a rebuild, and it was not a clean win. In the 51 days before, Bing sent 1,407 clicks from 3,022 impressions, a 46.56% click-through. In the 45 days after, 719 clicks from 6,733 impressions, 10.68%. Coverage more than doubled while clicks halved: it came back showing the site for many more queries it was much worse suited to.
