The search engine giant formally announced last year that it considers page speed as a ranking signal for mobile searches. It was already using the factor to finalize results of desktop searches. All these facts point in only one direction, that you need to ensure a good experience to your smartphone-using audience. In this post, we are providing information about how to spot and fix low mobile page speed in WordPress. In case, your interface is taking too long to render in visitors’ browsers, then your traffic will fall and your business will suffer. Let’s see how you can resolve the issue. 

How To Detect Low Mobile Page Speed?

Many people might be unaware that their mobile website has become slow. It is essential that you make periodic assessments of your interface to identify if there is a problem or not. Here we will show you how you can detect low page speed of your mobile website.

1. Run A Test On The PageSpeed Insights Tool

You can test your website’s speed on the Google PageSpeed Insights tool. Users need to enter the URL in the specified field and the service will provide a score between 0 to 100. Anything above 85 is considered to be a good grade. The report will also include some valuable suggestions for improving your score. It is a free service and you do not need to pay any fee to use the tool. Go to the PageSpeed website, enter the URL of your website and click Analyze. You can switch tabs to check the speed of your mobile and desktop versions.

2. Test Your Competitor’s Websites

It is not that a low score will always indicate poor performance. In some categories such as e-commerce, the loading time can be much greater across all interfaces. In order to establish whether there is a problem or not, you need to test your competitor’s websites as well with PageSpeed Insights. Select three or four websites and check out their performance ratings on the service. If your scores are poor in their comparison, then your loading speed really needs a boost.

3. Test The Websites On A Traffic Estimator

The main objective of the exercise is to find out whether your mobile interface’s speed is affecting its traffic and SEO performance or not. Test your website along with all the competitor’s interfaces assessed in the previous step on a traffic estimator. These tools will conduct an audit of all the websites and provide you with a report. This will help you assess where your interface ranks as compared to your rival websites. If you figure out that your performance is below par, then it is time to take the necessary steps.

Tips To Fix Low Mobile Page Speed

The ideas to fix low mobile page speed in WordPress are provided in your PageSpeed Insights analysis itself. Scroll down and you will find some recommendations along with the estimated time saved. 

The following tips will help you address the issue and improve your PageSpeed score.

1. Eliminate Render-Blocking Resources

Take a look at the image given above and you will find this suggestion on top of the list. This means that a page is not rendered in a browser unless the JavaScript and CSS resources are loaded. In case, we eliminate this error we will reduce an estimated 3.28 seconds from our loading time. The issue can be resolved by loading the JavaScript asynchronously. In case, you just converted PSD to WordPress and switched from other formats, then you must be wondering how to do the process. It can be done easily by using a plugin like Async Javascript.

2. Upload Only Optimized Images 

One of the most common reasons for slow websites are images with large file sizes. You must be careful and only upload pictures after they have been properly optimized. PageSpeed recommends you to use photo files in next-generation formats like JPEG 2000 and WebP. These file formats have better compression which allows images to load quickly. You can also use image optimization plugins like WPSmush to automate the entire compression and optimization process.

3. Reduce The Server Response Time

This is another recommendation made by the tool which can shave off 1.33 seconds off our loading time. This issue arises mainly because you are not using an efficient website hosting service. The problem is mostly faced by interfaces which are operating from shared environments. You can fix the issue by migrating to a better plan. Website owners can also use a content delivery network (CDN) to speed up things. They can also use a caching plugin like W3 Total Cache.  


The loading speed of your mobile pages is an important UX factor which can affect the overall performance of your website. The best way to ensure a good loading speed is to hire a reputed WordPress development company which will use the best practices to craft your interface. This will optimize the website for speed right from the beginning.
