Bing Webmaster Tools words this more scarily than it needs to: ‘URL cannot appear on Bing.’ That applies to the exact URL in the inspection box. It doesn't mean the destination, the domain or the rest of your site is blocked.
One homepage can have four URLs
To a person, http://example.com, https://example.com, http://www.example.com and https://www.example.com all look like the same website. To a crawler, they're four URLs. A clean setup picks one and permanently redirects the other three to it. When the redirects are right, our local SEO checklist for home service companies covers the rest of your local search setup.
If https://www.example.com redirects to https://example.com, Bing is correct not to index the www version. Inspect https://example.com next.
Check the destination, not the signpost
- Copy the destination URL shown by Bing.
- Inspect that exact destination in the Live URL tab.
- Confirm the response is 200 rather than another redirect.
- Check that crawling and indexing are allowed.
- Confirm the canonical points to the same final URL.
- Make sure internal links and the sitemap use the final URL too.
Why the dashboard can look out of date
The inspection card shows the last crawl date. If you fixed something after that, the old result stays until Bing fetches the page again. Bing also notes that its Live URL test doesn't follow a redirect, so inspect the destination as its own URL.
When to investigate further
- The final destination creates another redirect or a loop
- The redirect lands on an unrelated page
- The sitemap still contains redirecting URLs
- The final page has noindex or points its canonical elsewhere
- Bingbot receives a different response from normal visitors
A blocked login page is a different issue
A site scan may complain that an account login is blocked by robots.txt. That's normally fine. Login, account, admin, API and private report pages belong to the app, and nobody needs to find them in search. What matters is whether your homepage, service pages, industry pages and articles can still be crawled. Bing's own webmaster guidelines list what it asks of a site.
