Hello, I'm Quinn and here to help!
I didn’t do a full technical audit, but I checked the site, and nothing obvious stood out. Bing sometimes removes sites from its index even if they work fine elsewhere. This can happen due to crawl issues, quality filters, duplicate or thin content, security flags, or even false positives.
To fix this, go to https://www.bing.com/webmasters. There, you can use URL Inspection, check for crawl errors or blocks, review your robots.txt and meta tags, and resubmit your sitemap. If everything looks clean, you can request re-indexing or wait for Bingbot to re-evaluate the site.
