"The new checker builds on the suite of quality assurance tools offered by W3C to help authors and authoring tool developers create clean content," said Tim Berners-Lee, W3C director, in a statement. "Clean content offers a number of benefits to authors and users alike. The mobileOK checker does a nice job helping you improve your content one step at a time. Your mobile audience will thank you each time you improve your score."
The tool, created by the Mobile Web Best Practices (MWBP) Working Group is based on mobileOK Basic Tests 1.0 and uses the W3C validator.
To try it out, click here and submit the URL of your website. You will receive a score out of 100. The warnings are split into the following categories: markup; style sheets; images/objects; user input, at the HTTP level; and links.
If you type in www.google.com for URL, you'll notice that the whole result bar is green and displays a message: "This page is mobileOK".
The implementation report shows a list of websites that pass the test and that are mobileOK. Amongst these is the Google search engine, mobile version of Wikipedia and Milan News. Amongst tools that render content appropriate for mobile devices are Wordpress mobile plug-in, Merkur and MobileAware.
