Bing, Yahoo and DuckDuckGo - plus others
Having fallen foul of posting content that I subsequently wanted to remove or modify, I started making the same queries using these other search engines.
It seems that the content was still showing in the SERPs of these search providers.
Removal of content from these other services
Simply deleting the pages from my website does not remove the listing from the other services. In fact it would seem that I need to have a modified version of the original page.
This modified page(s) is needed for the page(s) to get reindexed. The problem is I need to add the names and keywords used to make the search back to the page. This is problematic for me as I have said that I have removed the posts and I don't want to change the content to reflect a positive view to counter what I had said before.
