My website was previously properly indexed on Bing and I was getting in regular Top search results and also enjoying enough visitors on my website greedandfearindex.com but from recent few weeks, my website experienced an instant downfall in impressions and soon turned to zero.
Instead, I regular post my articles on my website and submitting it on Google and Bing.
Google smoothly indexes my articles webpages, but Bing sometimes indexes and some times says, "The inspected URL is known to Bing but has some issues which are preventing indexation. We recommend you to follow Bing Webmaster Guidelines to increase your chances of indexation." However instead of Indexing, any of my webpages did not appear in of Bing SERP (Search Engine Result Pages) and also have a zero impression.
I approached for ticket to get details on why my website got deindexed, it said issues will be resolved and will reply back to me within 10 days. Today, it passed more than a month, and I still waiting for their loveletter.
