This test checks to see whether the organization's website is optimized for mobile devices.

Why do we test for this?

Mobiles and tablets are increasingly used to browse the web. Most websites are not designed to work on the smaller screen sizes that these devices have, so it is considered best practice to make your website adapt to give the visitor a better experience.

Some websites that use Adobe Flash may not work on a mobile device at all.

How do we test for this?

There are a few common ways mobile sites can be made:

In order to detect the first two options, we try visiting the homepage of the website being tested using a mobile user agent. If the server redirects us to a different website, we know the website employs the first technique. If this is not the case, we then look at the HTML that the server sent us using a mobile user agent and compare it to the HTML when accessed normally. In order to detect the third technique, we analyse all of the CSS on a website to see if it contains any media queries.

If the website is not optimized for mobile devices, we check if the website uses Flash which cannot be seen on mobile devices to determine if the website is likely to work on a mobile device at all.

What can I do about it?

Consider adding media queries to your CSS which optimize the site for mobile devices. If the website uses Adobe Flash, consider recreating the website in HTML.
