The Causes of Slow Mobile Page Loading Time

These days, having a mobile-friendly site is crucial to your business since most consumers are already on their smartphones. With this trend becoming a vital aspect of digital marketing, businesses have to keep up with what’s latest and make sure that the customer experience of mobile users meets their needs and wants.

According to Tractus’ research, 40% of the consumers won’t stick around on a website that doesn’t load in more or less three seconds. This means that it’s up to you to make sure that your business’ website can completely load within three seconds.


Although bad internet speed is usually at fault for slow page loading time, the website’s components may also part a role as to why a site loads slowly.

Here are the 7 common issues to look out for when trying to troubleshoot your slow loading mobile site.

#01 – Big-Sized Images or Videos

Obviously, if your website has a lot of big sized videos or pictures in it, then it will slow down. This is because a website needs time to process a request to the server before it loads information on the page. If the image or video sizes are too big, then the request time will take longer than normal since big-sized files take a longer time to download.

The solution here is to upload pictures in JPEG format instead of other formats such as PNG. JPEG formats are smaller in size and can compress the image without compromising the quality. As for the videos, the best format to use is MP4. The MP4 format can compress the file size and retain the video quality. Also, MP4 formats are read automatically by smartphones, so if a smartphone user downloads a video from your site, the user’s device can stream the video immediately.

#02 – Unnecessary Components

The goal of mobile-friendly site is to allow the viewers to use your site on their mobile device easily and conveniently. Although mobile responsive site adjusts the size to fit in the smartphone’s screen, adding unnecessary components will make your site load slower. Too many CSS or JavaScript codes will definitely slow down your mobile-friendly website. The key is to display only the most essential information.

If you like, you may use mobile website speed checkers like Google PageSpeed Insights to get the details on what’s slowing your website down.

#03 – Long Document Object Model Ready Time

In mobile marketing, one of the terms that you have to be absolutely familiar with is the Document Object Model Ready Time or simply, the DOM Ready Time. This is the time it will take for a browser to load the code of your website. If the receiving time of your website’s code is too long, then that means you have to modify your codes to improve the receiving time.

The DOM Ready Time of your mobile site is crucial to your business because it determines the bounce rates of your customers. If your site has a slow DOM ready time on the first-page visit, then your business will have higher bounce rates.

For this case, it is recommended that you concentrate on improving your DOM Ready Time above everything else so that you can boost your mobile page speed. You can do this by decreasing your JavaScript components since JavaScript codes are harder to process.

#05 – Un-optimized Elements

If your website is not optimized properly, then the overall loading time will slow down. Aside from decreasing elements in your page, another thing you can do is optimize your photos and fonts so that the loading time becomes faster.

In addition, minimize redirect links since they can seriously affect your page speed, especially in mobile devices to improve onpage seo. Redirect links take your viewers from one web location to another, which may cause loading issue. If using redirects isn’t necessary at all, then it is best to just avoid them.

#06 – Poor Web Hosting Service

If you’ve done everything that was recommended above and your site still loads slowly, then you might have a problem with your web hosting. Sometimes, it can be the inefficient web hosting server that affects the mobile page speed.

How do you know if your web host is the problem? You may use website speed checkers like Bitchacha to see the details of your host’s performance.

There really isn’t much you can do if your web hosting server is performing poorly other than to switch providers.

To avoid having to do all that, you may want to think twice before getting a cheap hosting. If you expect your website to have a lot of traffic, invest in a good quality web hosting or better yet, a dedicated server hosting.

#07 – Outdated CMS

If you are using a Content Management System (CMS) to manage your website, then you have to make sure to update it regularly. Updating your CMS enables you to get all the updated plugins and software versions. So, the simple solution to this problem is to update your CMS whenever there is an update available.


To keep people satisfied with your website, you have to make sure you give them a good user experience. Ensuring that the website loads fast is the first step to take. With smartphones now being the primary device that is used for browsing, you have to make sure that your mobile website works fast too. If you can give your mobile users a good customer experience, they’ll definitely stay with your brand.
