Most of us know by now how important it is to have a mobile friendly website, with Google constantly promoting its significance through its mobile friendly algorithm updates, as well as the upcoming ‘mobile world’ updates to Adwords.

But how many of us actually know how mobile friendly our websites are? And what exactly do we mean by ‘mobile friendly’?

You may class mobile friendly as a website that simply displays correctly on devices such as smartphones and tablets. You probably know that it should be easy for the user to read, navigate and scroll on their device. But have you ever considered other factors such as page speed and performance? These are just as important as how useable or ‘friendly’ your website is on a mobile device.

The recent launch of Google’s new Test My Site tool, which looks at both page speed and mobile friendliness, could be a clear sign that businesses should now be looking deeper into their overall mobile experience. Not only could performance indicators such as the mobile page speed of your website eventually become a factor in where your website sits in the mobile search results, but it will almost certainly have an impact on your overall mobile user experience.

Even if you think your website looks OK on a mobile, why not delve a little deeper? There are many tools out there that can help us understand the bigger picture when it comes to mobile.

Let’s start with the new Test My Site tool from Google.

Test My Site seems to be a combination of Google’s mobile friendly and page speed tools in one place.

This tool is quick and easy to use, simply enter your URL and Google will give you three scores out of 100. One for ‘mobile friendliness’, one for ‘mobile speed’ and another for ‘desktop speed’. The tool will also provide you with a free report on how to fix errors and improve your score.

  • Nice visual overview of how mobile friendly and speedy your website is
  • Provides guidelines on how to improve relative performance of the URL tested


  • Only looks at individual URL’s, rather than looking at the domain as a whole – just because one page on your site passes, doesn’t mean every page of your site will
  • You are limited to a maximum of three reports per day
  • It can take up to 24 hours to receive the free detailed report

The Mobile Usability Tool can be found within the Google Search Console, and can be used to identify pages on your site with mobile usability problems.

The good thing about this tool is that it looks at your site as a whole, rather than just one URL. Errors detected are presented on a graph, showing the number of pages which have specific mobile usability errors.

Errors found are grouped by ‘type’. Simply click into the error type to see specific pages affected by that error. The mobile usability tool will even provide a list of instructions on how to fix errors.

The tool looks as mobile usability factors such as flash usage, viewport, font size and touch elements.

Similar to the Google mobile friendly test tool, Bing have released their very own version, named the ‘Mobile Friendliness Test Tool’.

The tool analyses a single web page, and evaluates it for ‘mobile friendliness’ looking at key factors such as viewport and zoom configuration, width of page content, text readability, page spacing and plugins.

Bing states that making pages mobile friendly can help you to rank better in Bing search results on mobile devices, so it’s worth taking a look at how your website scores.


  • Free and easy to use
  • Gives a visual representation of how your website looks on a mobile device
  • Simple, easy to understand results


  • Looks at individual URLs rather than the domain/site as a whole
