It's almost an year when Google had launched its mobile friendliness test tool. Now, the other premium search engine Bing has roped in its own mobile friendliness testing tool yesterday which will help webmasters to find whether a website is mobile friendly or not. The roll out hasn't come in hurry as Bing began preparing for it back in April by showing mobile friendly labels in the Bing search engine results.

The tool that they have released yesterday was expected to come a few months ago. Since, the tool is live now, we may expect a Bing mobile friendly algorithm in the next few months.
Along with the launch, the search engine has explained some specific factors that determines the level of mobile friendliness and also elaborated how these factors impact your website. These factors are:
- Viewport and Zoom control configuration
- Width of page content
- Readability of text on the page
- Spacing of links and other elements on the page
- Use of incompatible plug-ins
The Bing Mobile Friendliness Test Tool is now available in Bing Webmaster Tools under Tools & Diagnostics or navigate to it directly using this Bing Webmasters Tool. The tool runs checks on all of these key factors listed above and checks for and reports on resources that are needed to analyze the page fully.
