Bing, the American search engine owned by Microsoft, does not index absolutely all the Internet content, it evaluates the quality of pages before showing it to the users. This is reported by SearchEngines.
Bing has no intentions to show low quality, spam, and manipulative content in its index. Search employees Christi Olson and Fabrice Canal spoke about this in an interview with Search Engine Land.
Specifically, Bing does not want to index the following types of content:
- Blank pages
- “Garbage” content
- Broken pages
- Spam pages
- Malicious pages
If a site contains a significant amount of this kind of content, then it may be downgraded in search results or not indexed.
NIX Solutions adds that in the same interview, Bing employees said that the search engine, unlike Google, uses behavioral metrics in ranking.
We also add that in June, Bing updated its Webmaster Guide for the first time in many years. This update was the focus of the interviews with the search staff.
