Mobile-Friendly Test Errors: The Surprising Reasons Your Site Isn’t Mobile-Ready

From time to time, when people come in for important things like a mobile-friendly site, that needs to be done. As mobile users account for a large share of web traffic, making sure your website meets mobile usability benchmarks is essential for improving engagement, conversions, and search engine ranking.

The mobile-friendly test is another useful resource that will flag issues preventing your site from being an optimal experience on mobile. But, when it comes to actual website owners, there are errors that frustrate owners and affect how usable the site is.

We’ll cover the surprising reasons you might find your site is not mobile-ready, common mobile-friendly test errors as well as why they happen and how to fix them.

What is Mobile Friendliness?

Mobile-friendliness involves the performance and presentation of a website on mobile devices (e.g., smartphones and tablets). With mobile internet usage now exceeding desktop browsing, providing a smooth experience for mobile users is more important than ever.

With responsive design, a mobile-friendly website adjusts its layout and content automatically to fit different screen sizes, eliminating the need for users to zoom or scroll too much.

It also provides quick loading times, button sizes that are touch-friendly, readable text without zooming, and navigation through menus that can collapse. Mobile-friendly sites also avoid outdated technologies such as Flash, minimize form fields for better input, and disable intrusive pop-ups that degrade the user experience.

Giving preference to mobile–friendly sites for search rankings, optimizing for mobile is key to enhanced visibility within search rankings, even greater user engagement, as well as high conversion rates. Incorporating best practices such as image optimization, structured data usage, and consistent performance testing with Mobile-Friendly Test allows businesses to ensure smooth, accessible, and efficient browsing capabilities for their audience across devices.

Diagnosing Errors with the Mobile-Friendly Test

Mobile-Friendly Test assesses a site’s responsiveness, usability and general performance on mobile devices. When a website doesn’t pass this test there could be problems like bad user experience, slow load time and low rankings on search engines. So let’s explore some of the most common and surprising reasons your site isn’t mobile-friendly.

Did not set or improperly configured viewport

The viewport meta tag gives browsers control and guidance on a page’s size and scale across different screen sizes. If the above tag is missing, mobile browsers default to a fixed-width layout and the web page will not render properly.

Solution:

Make sure you have the right viewport meta tag in your HTML:

<meta name=”viewport” content=”width=device-width, initial-scale=1″>

This helps the page fit appropriately on various devices.

Content Not Scaling Properly

Users have fit the content on their device by zooming or scrolling but unless the content is responsive, users will have to zoom again. This happens when the layout is too wide with fixed width containers and large image files, or other non-responsible elements.

Fix:

• Avoid fixed pixel values, use relative units like percentages (%) and em
• Use CSS Flexbox or Grid for responsive design techniques.
• Use the srcset attribute to serve appropriately sized images.

Clickable Elements Too Close Together

This issue is flagged by when buttons, links or other interactive items are positioned too closely together to tap.

Fix:

• Tappable elements should be large (at least 48px x 48px as per Google recommendation)
• Ensure you have enough space between elements.
• Add minimum padding of the buttons to make it bigger in touch.

Text Too Small to Read

When text is small, users find it hard to read the content without zooming in.

Fix:

• Body text should have a minimum font size of 16px.
• Use relative font units rem or em for responsive design.
• For screen readers (someone using a computer with the option to read the page back), don’t use images of text as these don’t scale (get larger) and aren’t easy to read by a screen reader.

The Deprecation of Flash and Outdated Technologies

Most mobile browsers do not support Flash and it may make your app hard to use.

Fix:

• Use HTML5, CSS3, and JavaScript in place of Flash elements.
• Do not forget to make it responsive, finally use latest frameworks as Bootstrap to make it mobile compatible.

Slow Loading Speed

Load speed is crucial for web mobile users, who experience high bounce rates with slow loading pages.

Fix:

• Use compression tools such as TinyPNG or WebP format to optimize images.
• Enable browser caching.
• The whole purpose of a CDN is to route content as fast as possible.
• Optimize requests and compress CSS and JavaScript files.

Pop-Ups and Interstitials That Are Intrusive

Sites that use popups that are unreasonable get penalized by Google.

Fix:

• Try not to use the full-screen pop-up; use non-intrusive banners.
• Do not cover important content with pop-ups.
• Use exit-intent pop-ups instead of regular ones.

Mobile redirects not configured properly

When a mobile user clicks on your desktop, they should not be directed to the mobile version, but to an unrelated or wrong one.

Fix:

• Use responsive web design rather than separate mobile URLs.
• Avoid server-side redirects that don’t correspond to the mobile version.
• Test redirects with Google’s Mobile-Friendly Test and repair broken links.

JavaScripts, CSS or Images Blocked

If Googlebot can’t access critical assets, your site will likely be marked as non-mobile-friendly.

Fix:

• Check your robots. txt file and prevent it from hindering functions such as HR and recruitment.
• Find Blocked Resources with Google Search Console

Forms and Input Fields, not optimized

Frustrations can arise if users have to fill forms that are difficult to be filled using mobile.

Fix:

• Most importantly, use large (preferably “touch screen” size) form fields that are easy to tap.
• Use autofill and input field constraints (like type=”email” on email fields).
• Offer descriptive labels instead of placeholder text

Structured Data for Mobile SEO Is Missing

While structured data makes it easier for search engines to crawl the content of a website, improper implementation could negatively impact mobile visibility.

Fix:

• Test your structured data with Google’s Rich Results Test.
• JSON-LD format for easier implementation
• Maintain consistency for mobile and desktop structured data

Not Considering Accessibility

Mobile usability isn’t just about being responsive — it has to be accessible for users with disabilities as well.

Fix:

• Use enough contrast to make text as easy to read as possible
• Use labels for better navigation with ARIA
• Use descriptive text (alt) for images.

Heavy Use of Custom Fonts

Custom fonts can add load time to the site and can delay rendering on mobile.

Fix:

• Reduce the use of custom fonts.
• Where feasible, use system fonts.
• Font loading: optimize with font-display: swap

AMP (Accelerated Mobile Pages) Not Supported

AMP aid in loading pages on mobile faster

Fix:

• Accelerate load times and SERP through AMP on priority pages.
• Run your AMP pages through Google’s AMP Test.

Too Many Animations and Transitions

Over animated results can slow down performance, especially on lower-end mobile devices.

Fix:

• Minimize transitional animations where possible.
• Optimize CSS animations and inject JavaScript.

Lazy Loading Images Not Used

If we load all images at once, that can slow down your page speed.

Fix:

• Use loading=”lazy” attribute for lazy loading
• Utilize contemporary formats such as WebP for quicker rendering.

Not testing Mobile devices with various form factors

Web pages are rendered differently on different devices.

Fix:

• Test on several devices and browsers.
• Testing across devices is where BrowserStack or LambdaTest come in.

Not Updating Mobile Usability Regularly

Web standards evolve constantly.

Fix:

• Regularly check the mobile-friendly status.
• Stay in line with Google-indexed pages for mobile optimization.
