Everyone uses mobile phones today, you see people on mobile devices all the time. Wherever you go, walking, waiting for the lift, public transport even behind the wheel of a car!

Mobile devices are the main way people access the internet. That’s why Google uses the mobile version of your page for ranking and indexing purposes.

When people want information on a product or service or want to research a topic the first place they go is the internet – and specifically Google.

If your website is not showing up for relevant queries from potential customers you are losing business.

Having a mobile friendly website will improve your ranking position with Google and other search engines.

Mobile Usability: Reasons Your Website Doesn’t Work On Mobile Devices

Not getting the organic traffic to your site you expected? It could be your site just doesn’t work on mobile devices properly.

Common issues found on non-mobile friendly websites

Large Popups

Text too small

Images too large

Site too slow

Buttons/links too close to each other

You need to find and fix all these issues to improve your rankings. The next section we will get into how to solve these problems.

Okay, My Page Is Not Mobile Friendly. What Should I Do?

The good news is fixing your mobile issues isn’t difficult. The first thing you need to do is test your website using the Google mobile usability test. This will provide a report on mobile issues found on your website.

You need to test not only the home page but specific article pages to find all the mobile issues you have. More on how to do a comprehensive check of your website later.

Mobile Usability: Take the Test

Take the test here:

If the page doesn’t have any mobile issues you will see this result below:

Only one page is tested, it’s possible you could have mobile issues on other pages even if you get the all clear from this test. Let me explain the possible errors you will get from the report.

Error #1: Uses incompatible plugins

Some technologies are old fashioned and not used in modern web browsers. A common technology that is incompatible with mobile devices is Flash. It should not be used on your website. If you need to animate parts of your website there are modern ways that are supported by mobile web browsers.

→ Use a modern, responsive, mobile friendly theme for your website

This site uses GeneratePress, read my review here: GeneratePress review: Fast WordPress theme in free and premium versions

Error #2: Content wider than screen

This error occurs when the user has to horizontally scroll to see your content. This provides a poor user experience and quickly becomes annoying to users.

Read more about size content from Google here:

→ Avoid using fixed width and position values on your page. Ensure images can scale to page size.

Error #3: Text too small to read

The font size on your website is too small to easily read. This will causes visitors to squint or have difficulty reading your content. Many users will abandon your page than try to continue reading.

You need to set a minimum font size across your website.

My website had this error. I fixed it by setting a minimum size of 16px for all elements.

→ Set minimum font size on all elements to 16px

Error #4: Clickable elements too close together

I also got this error for my website, specifically the social media sharing buttons were too close together.

The solution to this error is to add padding to all blocks that have clickable elements. Typically this will be navigation bars, footer links, sharing buttons etc.

You may need to make several adjustments and keep retesting to fix this completely (I know I did).

→ Add padding to clickable elements (navigation links, sharing button etc)

Error #5: Viewport not set

The page tested does not contain a viewport property that tells browsers how to scale a page for the screen size of the device.

This problem is caused by your theme. Most modern themes should set this property for your automatically. You should not need to set this property manually.

→ Change your theme – all popular themes will be mobile friendly by design

Error: Viewport not set to “device-width”

Similar to previous error. Again this problem will not occur with a modern mobile friendly theme. As above the fix is to change your theme.

Mobile Usability: Don’t Forget Other Search Engines Like Bing

Check your page is mobile friendly according to Bing, important for ranking well in the Bing search engine:

Mobile Usability: Monitor Using Google Search Console

Use Google Search Console to monitor your mobile usability for free. From the left hand sidebar there is a Mobile Usability link. This page has two panels. The first panel shows the number of usable and not usable pages on mobile devices:

usable and not usable pages on Google Search Console
Usable and Not Usable pages according to Google Search Console

It’s very important when Google indicates that one or more pages are not usable that you find the issues and fix them. Mobile usability is a ranking factor and you will very likely see a drop in your ranking position until you have fixed and verified the issue.

As you can see from the image about I had mobile issues, once I fixed the issues I immediately verified the fix using Google Search Console again.

The second panel shows what mobile issues you have on your site. You can click on the issues to see exactly what pages have each issue.

Once you have fixed the issue on your website verify the fix on Google Search Console.

If you have pending issues you will see each web page on your website with this issue listed. You can click on the “VALIDATE FIX” button. Google will then schedule a re-test of that page to verify you have fixed the issue.

You can click on “SEE DETAILS” button to see the status of any pages Google found issue with. The details page is shown below:

verify mobile issue is fixed on Google Search Console

From the other tabs you can see PASSED, FAILED and OTHER.

It’s good to keep monitoring Google Search Console to ensure all your pages are mobile friendly.
