I personally can see the “Deep Search” icon at the top right of the Bing search box after conducting a search in Bing. Here is a screenshot of the “Deep Search” icon at the top right of the Bing search results page:When you click it, it takes you to a screen to refine your search and says “Taking a second look at your search…” and then it does a number of related searches to come up with the search results. For the [search engine optimization] query, Bing Deep Search is unable to return any results. Deep Search results ranking. Deep Search won’t load as quickly as regular search results.
