How to Make Your Mobile Site Load Faster?

1. Check Core Web Vitals & PSI

Core Web Vitals are metrics evaluating website speed and performance. CWV are one of the ranking factors announced at the end of August 2021. Along with responsiveness, security, encrypted connection, and lack of intrusive ads, Core Web Vitals will become an essential component in deciding about website positions.

Why do we talk about this?

The introduction of Core Web Vitals as an additional ranking factor is related to the growing role of user experience. Google clearly indicates that SEO should aim to increase users’ satisfaction with the search results. Only then it’s possible to reach high positions in the organic search results.

If you use PageSpeed Insights (PSI) to analyze your website, you’ll receive information concerning:

  • LCP (largest contentful paint) – it’s a metric that shows the loading speed of a website. It measures the time the browser needs to load the largest element on the page,
  • FID (First Input Delay) – it’s a metric that indicates the interactivity of websites. It’s the time counted from when the page starts loading until it’s fully interactive,
  • CLS (Cumulative Layout Shift) – it’s a metric that measures the visual stability of a page layout. It’s calculated as the sum of shifts that are visible during page loading. This includes unexpected shifts, i.e., those unrelated to user interaction.

2. Compress & Optimize Images

3. Keep Redirects Down

Redirects are a must when you want to inform the search engine that your site can be found at a different address or if you want to eliminate the problems with subpages and links that don’t work properly.

However, too many redirects can negatively affect the website loading speed, as the server needs time to find the original URL.

Therefore, you should reduce their number to the minimum to ensure that they don’t affect the page loading and don’t discourage users.

4. Make Your Web Design Simpler

Although extra banners and pop-up windows are supposed to attract users’ attention and increase their interest, the excess of these elements may negatively affect the website loading time.

When designing a website you should analyze which elements and functionalities are essential. It’s worth resigning from some extra features to boost page loading speed.

While sophisticated page design looks impressive, too many extra elements may not only slow down the website loading speed but also discourage users from staying on the site. The codes essential to design such a page can needlessly overload it.

When creating a website, you should go for simple yet original solutions that will draw users’ attention but at the same time won’t overload or slow down your site.

5. Don’t Use Custom Fonts

How to improve mobile site speed? Don’t use custom fonts!

Why? Because if you choose them, the server will first need to download them before it shows them to users. This means that website loading may take significantly more time.

Moreover, there is always a risk that the fonts won’t be displayed properly. For this reason, it’s recommended to rely on system fonts.

6. Use Website Caching

Mobile browsers are able to remember pages and save data on tablets or smartphones in order to use it later. This can have a noticeable impact on page loading time.

Website caching will streamline the page loading process, and this, in turn, will positively influence the way users perceive your site.

7. Minify Your Code

Code minification means simplifying the code and getting rid of any unnecessary characters. It doesn’t affect or modify the functionalities and website operation.

By deleting the extra parts of the code, you reduce the page weight. This results in speeding up the loading time of the site.

8. Reduce the Number of Steps to Purchase

What else can you do to improve mobile speed? You can analyze all the steps the potential customer has to take to finalize transactions, sign up for a newsletter, or perform any other activity that’s of importance to your business.

If the process is time-consuming and involves 5, 6, or more steps, think about how to speed things up. Removing some unnecessary elements will allow you to get rid of the code and improve your page loading time.

9. Use Lazy Loading

Lazy loading might be the key to improving your page loading time.

In a nutshell, it’s about using special scripts to delay the process of loading images, videos, or graphics that aren’t displayed to users right away when they enter the site.

This helps to prevent situations when your website loads for 10 seconds only because of one or two large pictures that won’t be shown to users until they scroll down the page for 2 minutes.

To implement lazy loading, you can benefit from a free plugin: Lazy Load by WP Rocket.

10. Choose the Right Hosting and Server

Selecting the appropriate hosting and server is an extremely important issue that affects the website loading speed. In this case, you ought to avoid free solutions as they’re rather ineffective and slow.

Moreover, they frequently display numerous ads and can easily overload the page. Analyze your business and website needs to determine the functionalities and features that are the most important for you. Before making a decision, check server reliability.

11. Use Mobile CDN

Cloudflare is a Content Delivery Network that helps you make sure that users are always close to your server, regardless of their location in the world. This means that your website will load equally fast both for people who are in Japan and those who sit in a coffee house in London.

Using a mobile CDN is particularly important if you plan to go international.

Remember that first impressions count. If people in your target country see that your page takes a long time to load, they’ll probably leave it and won’t visit it again.

12. Update to the Latest Version of PHP

Hypertext Preprocessor also known as PHP is a programming language that makes it possible to create dynamic website content. Thanks to it, you can easily make your page more appealing, interactive, and eye-catching.

Using PHP correctly can have a positive impact on page loading time and SEO.

How is it possible? Your site gets more interesting for users and improves its overall loading speed. To update your PHP version, enter the settings panel of your server, and look for a relevant section with PHP settings.

13. Use Only the Plugins You Need

Installing too many plugins can have a negative impact on your website loading speed.

This happens because plugins send additional HTTP requests and DB queries. Moreover, some available solutions require the use of custom scripts. All this translates into extra JS files and more time needed to load all of them.

Remember that simplicity is the key to success. Keep your page functional, but try not to gild the lily.

14. Reduce the Server Usage

When users visit a given website, all its content, including texts, graphics, and source code, is processed by the server. This increases the loading time of your website.

So, how to increase website speed on mobile?

Start with turning on the GZIP function that compresses files. Thanks to it, you can reduce the weight of your website and consequently improve its loading time.

Where to find it? While some hosting companies have this feature switched on by default, it needs to be activated manually in other cases.

If you wish to reduce your server usage, you can also take advantage of special plugins which are responsible for shortening the website loading time. If you use WordPress, you can access one of these plugins:

However, when configuring the plugin, you should read the detailed instructions and tutorials or ask someone more experienced for help. Remember that incorrect configuration can cause errors on the website or prevent the site from being loaded.

15. Put JavaScript at the Bottom and CSS at the Top of HTML Files

Make sure that CSS is at the top of your HTML files.


Because the rendering thread has access to all the information about the style it requires to render the website content. If you put JavaScript first, it would need to analyze all the elements before moving forward.

Consequently, the rendering thread wouldn’t be able to show the page completely, as it simply wouldn’t have access to all the necessary style information.

How to Make Website Load Faster? The Takeaway
