Tips to make your website mobile-friendly

Mobile-Friendly Tool will show the problems on your website, as well as recommendations on how to fix them. Additionally, you can follow these recommendations. With their help, you can easily score better rank.

Tip 1: Do not create one more separate mobile-friendly website

Some developers came up with the idea of making a separate site for the mobile version. It means you need to cut out content with important information like photos, videos, etc., on a mobile site.

Moreover, by creating two websites with the same content, you will get two separate links in search engines. Therefore, it will cause trouble with trying to have the content show up.

Note: But if you have decided to do separate versions of your website, don’t forget to place rel=”alternate” mobile attribute. It’s an important step to prevent duplicate content penalty issues on your website. Don’t forget your website to check for duplicate content. So let’s sort out how the “rel=mobile” attribute works.

Add a special tag with the attribute link rel=”alternate” on each page of your desktop version. It must lead to the corresponding page of the mobile version. This will help GoogleBot find the content which is optimized for mobile devices. We need to point to search bots that there is another version of the website page.

Your piece of code will be composed like:

link rel="alternate" media="only screen and (max-width: 640px)" href=""

Secondly, each web page of mobile version should contain the canonical tag, which leads to the version of the same page but with the usual formatting:

link rel="canonical" href=""

Tip 2: You should only use responsive design

Responsive design is the best solution for a ‘user as a friend’ approach in website design. Why? Because it allows developers to make the site viewable on different devices and screen sizes. 

Responsive design helps to make images and layouts more flexible. It also keeps stylesheet media queries cascading from the beginning. The web page will figure out the user’s screen size and accordingly change the layout. It will greatly simplify the task for developers while creating a site and improve site usability.

Tip 3: Always use a viewport meta tag


The browser rendering engine determines the scale of the website size through the viewport. That is why it is critical to code for multi-device resources. If you do not use the viewport meta tag, your website will not work properly on mobile devices. It literally tells the browser how the page should fit the screen. So if Page Has No Viewport Tag, it is necessary to fix the issue.

What is more, there can be some other problems with the tag including viewport <meta> tag initial-scale being incorrect or when multiple viewport <meta> tags being found in the <head>.

Tip 4: Button sizes and font sizes importance

Button sizes as font sizes are very important for mobile devices. Why? With small website buttons, users may miss them or accidentally hit the wrong one. It is always annoying when your fingers literally cannot hit the right button because of its size. Apple recommends going with 44px by 44px button sizes or above.

Your mobile-friendly website should have a font size of at least 14px; it is not that big! By using a 14px size, you make sure that users will not need to use zoom in order to read the content on your site. You can use a 12px size only for labels and forms. It’s important to fix the issue if the font size is too small for mobile devices.

Tip 5: Images with high-resolution

If you consider your website with a high standard, high-resolution images are mandatory. The latest IOS, Android, and Windows mobile devices have high-definition screens. So, to avoid blurry or pixelated images, we recommend using very high-resolution images.

Tip 6: Do not use default zoom

We definitely do not recommend using auto-zoom for the mobile-friendly website. It can mess up layout elements like navigation content and images. Using meta tag will solve zoom problems automatically. But by default, zoomed images can appear too big or too small, which will annoy users because of having to waste time adjusting.

Tip 7: YouTube videos on mobile site

It is not that easy to use videos on the mobile website version. YouTube video is the best answer to this problem. Videos on YouTube combat all difficulties in viewing videos on mobile — in fact, YouTube already made everything for you; all you need to do is use it.

Tip 8: Wide user mobile experience

What does it mean? You can make a perfect website, but you should always provide a choice to your users. “View desktop version” or “go to the full site” is a necessary button because there are still users who prefer the full site interface, so give them this opportunity.

Tip 9: Always testing

Never stop testing! It is usually possible to make a better version. You should always think like a user and find out what can be further developed, changed, or even deleted. You can try Google’s mobile-friendly tester tool and check if your site is perfect for Google search.

  • Make tests with different moblie devices of different operating systems (Android, Windows, and IOS)
  • Make tests on different screen size devices (tablets, surfaces, and others)
  • Test not only the front page but all of them, all buttons and user actions
  • Ask your friends or a specialist to test it for you, as they should have a fresh look.

These tips should help you make your website mobile-friendly. Create maximum comfort for users to turn them into a permanent audience.

You can use mobile-friendly test right in your browser. Insert URL of the website you want to check, press Enter and get the results.
