Google sends mobile usability warnings to webmasters (and what you have to do now)

Some days ago, Google started to send email notifications to webmasters whose websites are not mobile-friendly. Basically, this message is a reminder that these websites won’t rank well in mobile search. Adjust your pages to make sure that they get better rankings.

How does the message look like?

Here’s an example message:

How to check if your website is mobile-friendly

Google has a tool that enables you to check if your website is mobile-friendly. Websites that pass Google’s test will be labeled with “mobile-friendly” on Google’s search result pages for mobile devices.

The tool is available here. Just enter the URL of your website and click the “Analyze” button. If your website passes the test, you will see something like this:


What can you do if your website fails the test?

If your website fails the test you probably have to adjust the design of your web pages. Instead of creating a separate website for mobile devices, you could use responsive design for your web pages.

If you use WordPress, there are many themes that support responsive design.

What to do if the testing tool says that your website is not mobile-friendly although it is

If the testing tool says that your website is not mobile-friendly then Google cannot access the mobile-friendly version of your site. According to Google’s John Mueller, this can have several reasons:

“1. Too much blocked by robots.txt.

Googlebot needs to be able to recognize the mobile-friendliness through crawling. If a JavaScript file that does a redirect is blocked, if a CSS file that’s necessary for the mobile version of the page is blocked, or if you use separate URLs and block those, then Googlebot won’t be able to see your mobile site. […] Don’t disallow crawling of your site’s CSS or JS files!

2. Cloaking to Googlebot.

Cloaking has been in our Webmaster Guidelines for a long time, it causes all kinds of problems. Some sites try to recognize Googlebot by looking for “Googlebot” in the user-agent, and will then serve it a “Googlebot-version” of the page (which is often the desktop page). If Googlebot-smartphone crawls and sees the desktop page, the page won’t be seen as being mobile-friendly. [… ] Don’t cloak!”

There are many more things that can cause problems with Google’s indexing bot. Check your website with the website audit tool in SEOprofiler to make sure that Google can index all pages of your website.
