Help: Showing up in Bing ≠ Being indexed in Bing
I noticed across several of my websites that 90% of the pages are indexed in Bing (submitted in Bing Webmaster Tool and reported as such in Bing Site Explorer) but when I actually search for a lot of them in Bing, they don't show.
I heard Bing has its own filter and may or may not show an indexed page in the SERP.
Does anyone have tips (e.g. technical SEO or else) to maximise the chances indexed pages do show in the SERP?
