Hello,
Our website howtoremove.guide was recently removed from the Bing and Yahoo index. The first thing we did was contact Bing Webmaster support to ask what the issue was since we did not get any notifications or messages in our webmaster dashboard. The email that we got back said “I have escalated the issue to our engineers and will get back to you once I receive an update.” Since then, we haven't received any word back from them, but we did not find any technical problems and we strongly believe we were manually penalized.
We've never had issues with a search engine before, so we are at a loss what to do. Could you please give us advice as to what technical issue our website might have or what could incur a deindex penalty in our case? We want to do everything that is possible to get back into Bing and Yahoo search results ASAP. The website has primarily affiliate content, so we are doing anything we can to clean everything up, but any recommendations will be incredibly useful to us. We are also open to contacting an expert on this, but we have no idea where to look.
