New Bing Webmaster Mobile Friendliness Test

[engine]

Bing has announced its new Webmaster Mobile Friendliness Test tool in Bing Webmaster Tools.

It spiders the page and and evaluates the the page performance against the factors noted below, and produces a result with a verdict.

It's going to be worth having additional research capability on this, thanks Bing.

The Mobile Friendliness Test tool runs checks on all of these key factors and additionally checks for and reports on resources that are needed to analyze the page fully but that we weren’t able to crawl due to robots.txt constraints. New Bing Webmaster Mobile Friendliness Test [blogs.bing.com]

When evaluating a webpage for mobile friendliness, the following key factors are considered:

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

Sounds as useless as the google one with the added disadvantage that at lease google's tool is public, not dependant on being logged/locked into a webmaster account.

Best mobile validator I've found is [validator.w3.org...] but even that has limitations.

And of course, these tools are out of date anyway. The original mobile restrictions were for narrow screens around 300px wide. Most mobile devices can now see complete web pages as well as a desktop can.

Not locked into a webmaster account..public..bing..

?..dangerous ( and erroneous ) assumption there..loads of phones in use at 800 x 480 and some even lower..

Most everyone I know uses a phone several years old w/ small displays and small resolution. I use a new, big phone but I'm not the average mobile user. I design responsive for 540x960 up to 2560x1440 resolution.

I agree with keyplyr.

My mobile implementations start at 320px landscape to allow the oldest phones to see the entire rendering without having to pinch zoom. They know they have an old phone and will switch to landscape automatically during page load to avoid having to zoom as much.

There might be some niches where big pixel phones dominate, but I'm not aware of what they are. This forum's charter precludes us from going beyond 'old yellow widgets' or similar pseudo references in identifying them. Forums for users of big pixel phones? LOL.
