November 22, 2023



Mobile-friendly websites are obviously better than those that are not and will probably rank higher in mobile search results, so making sure that your website is accessible through any type of mobile device is vital for SEO. 

Have you checked your website if it’s mobile friendly? Check out this mobile-friendly website checklist to determine whether you’re ready to be browsed on any device! Test it through Google’s mobile-friendly test tool to see how visitors see your site on their phone.

Why Should your Website be Mobile-Friendly?

Almost every internet user uses mobile phones to go online and browse for a couple of hours as their everyday routine and these numbers continue to go higher up to 2.7% yearly. In 2015, Google officially included the mobile friendliness of a site as a ranking factor in mobile search results. And today, the majority of people are browsing on Google using their phones.

There are millions of websites out there giving the users unlimited options when searching, so they’re obviously not going to tolerate any poorly designed and slow-loading pages. We don’t want a high bounce rate for your site, do we? With this being said, it’s clearly a must for web owners to make sure that their site is mobile-friendly.

Why is your Website Slowing Down?

Before proceeding to our checklist, let’s talk about the reasons why some websites become slow when viewed from mobile devices.

Excessive Scripts

There are various possible roots of a non-mobile-friendly website and one of it might have something to do with the Scripts. More scripts usually mean slower performance since scripts are a high contributor to a page’s weight.

Heavy Media Files

Just like the scripts, media files such as images, videos, gifs can be too heavy for your website and slow down your loading time. Too much visual content is not ideal and might contribute to a website’s weight.

Poor Mobile Navigation

If a user visits your page and finds it too complicated to function, that user is most likely going to leave your page immediately. Therefore, you should create a mobile-friendly navigation for your website to increase user engagement and attract more visitors.

Wrong Layout Choice

Non-mobile-friendly layout designs may also lead to poor user experience. Have you ever viewed a website on your mobile phone and the content in it breaks, the navigation tools are scattered everywhere, and you don’t even understand the texts. If you’re wondering the reason for this, it’s because the layout they used isn’t mobile-friendly. 

How to Make your Website Mobile-Friendly

Moving on to the real deal, the question is: how do you actually make a website mobile-friendly? 

If your website has not yet ever been optimized for mobile devices, there are quite a lot of things you need to work on before you can actually call it mobile-friendly, but it might also be just as easy as modifying your current page templates depending on your current website status.

You can use tools such as Chrome DevTools to analyze and optimize websites for better performance, user experience, and overall quality. There are also some available third-party services such as Screenfly and BrowserStack that allows you to test your website in a much wider range of resolutions.

Mobile-Friendly Website Checklist

Here, we listed the things you’ll need to ensure that your website is working at its finest regardless of what type of device your readers use!

Choose a Responsive Website Design or Template

To put it simply, your website’s design is responsive if it works on all devices meaning it has different versions that fit all types of devices and appears as it, depending on what type of device your reader is using to browse. This allows the website to adjust to various screen sizes without any issue. Google wants pages with a responsive design; thus your mobile web page has to be as good as its desktop version.

You may use BrowserStack’s responsive design testing tool to check your website’s appearance on different device models.

Overall Content Readability

Another thing that matters a lot is the readability of the content on your website. Make sure to pick the right text sizes and fonts so readers may easily see what they need from your site. This will keep your visitors to keep browsing your page and will lower your bounce rates.

The commonly recommended font size is at least 14px on desktop so it could appear readable on mobile devices but still, you have to test it out first. 

Work on the Navigations

Make sure that users are able to access the information they need from your site as quickly as possible. Improve your page’s button sizes, update their placements, and check if it’s easily clickable.

Pay Attention to Visual Content


It’s crucial that a website contains just the right amount of visual content. A website may slow down if the images and videos in it are too heavy. Remember, these are one of the highest contributors to a page’s weight! And since website speed is a ranking factor for Google, slow or heavy websites will fall behind their competitors in search engine results pages (SERPs).

Take note, having high quality visual content is just as important as them not being too heavy. Make sure that the images and videos you include in your site are optimized and have high resolution, so they don’t get blurry, zoomed, squished or distorted when viewed on mobile devices. Otherwise, user experience will be affected negatively.

TIP: Compress images when uploading. Make sure you get to reduce the file size without compromising on its quality. For videos, it’s ideal to use a third party so its weight doesn’t largely contribute to your page.

Make the website compatible with both orientations.

Another important factor that shouldn’t be left out is your page’s flexibility. It should be able to work both in Landscape and Portrait mode. Make sure that all functions work in both orientations without glitches and distortions. It’s always best to check it on real devices!

Optimize your Page Speed

As previously mentioned over and over, speed plays an important role in users’ first impression of your website. Slow loading pages basically gives you a high bounce rate. Optimize your website and make sure that phone users can access it easily.

Make sure pop-ups are not aggressive!

Last but not the least, pop-ups! Too many pop-ups may cause users to think that your page is spammy or risky. One common scams that is circulating among mobile users are hacking and fake pop-ups, thus having too many of these on your website, especially if it’s aggressive and leaves them with no choice, visitors might be scared off and immediately leave your page.

While pop-ups can be helpful, the use of it should be limited. Additionally, using pop-ups that hide your main content or require users to navigate through them before viewing it will negatively impact your Search Engine Optimization (SEO) rankings.

Keep in Mind

It’s always best to test your website throughout the entire development process. While creating a mobile-friendly website is crucial, it’s also important to make sure that the mobile-optimized website offers an optimal user experience on all device-browser-OS combinations.
