A few days ago, I migrated from Flarum to Discourse, but I encountered a very serious issue: my website’s weight on the Bing search engine dropped significantly, and I need your help!

why don’t you compare the crawler view from your flarum site with that of your discourse site? Use curl and the google user agent, for example.

Pick a couple of views, e.g. topic list and a topic, then copy the html of both into a Chatbot and ask the AI to compare the html of both.

You may need to bring your flarum site back up to do this comparison if you have switched it off. Just put it temporarily on a subdomain - e.g. flarum.

Bing’s migration docs says that SERP fluctuations after a migration are expected and “likely a temporary decline in organic search visibility.” Website Migration with Bing | Bing Webmaster Blog

Have you checked that the old Flarum URLs are resolving with permanent redirects?

Already checked, all 301 redirects have been set up.

So this could just be the temporary decline perhaps. We always see a drop when we migrate someone to Discourse but it self-corrects pretty quickly.
