Bing's new webmaster guidelines list six main categories that Bing uses to rank your web pages:

1. Relevance

The content of your web page should match the intent behind the search query. If the web page contains the search term, and if the links that refer to the page also contain that search term, the page is relevant to Bing. Bing also considers synonyms or abbreviations that have the same meaning as the original search term.

2. Quality and credibility

Bing evaluates page to determine the quality and credibility of these pages. That includes factors such as the reputation of the website and/or the author and the level of discourse (articles with citations and references to sources are considered a higher quality than articles without sources). According to the guidelines, Bing might demote pages that contain offensive statements or derogatory language. The completeness of the content and transparency of authorship also have an impact.

3. User engagement

The interaction of users with the search results has an impact on the rankings. The number of clicks on a result, the time spent on the clicked pages and the number of people who return to Bing after clicking through to a page has an impact.

4. Freshness

Bing prefers content with up-to-date information. Some websites contain content that wills till be relevant years from now, other websites might have content that is going to be out of date quickly.

5. Location

The location of the user (country and city) has an impact on the rankings, as well as the language of the document and the location of other visitors of a web page.

6. Page load time

Many visitors will leave a website if it has a slow load time. For Bing, slow websites provide a poor user experience and an unsatisfactory search result. Webmasters should try to balance page load speed with positive user experience.
