Things to pay attention to while running Website Speed Test

These tools are great to give you an overall ideal of your site performance. However, you should be able to interpret the results properly too. If you are completely new to website management, you may have to be aware of certain other factors to be able to read the results effectively.

Configure Caching and CDN before running speed tests

Caching is one of the most effective ways to improve site performance. You will have to ensure that you are using a caching tool before running website speed tests. As you probably know, CDN or Content Delivery Network is another popular performance boosting service for websites. With a CDN network across global locations, you will be able to serve static files of your server from a location closer to the user. This will contribute a lot in improving page load speeds. So, your website speed test results will show marked differences based on whether you have enabled caching and CDN.

Repeat tests

According to experts, just doing a singe speed test won’t give you accurate results. You will have to do the speed test two to three times to optimally gauge the site performance. Moreover, to get the correct perspective on speed, you have to see it when everything is loaded from cache. If you run a speed test without loading the site from the cache, the page speed could be significantly lower.

Try changing locations

You may also have to do the speed test from different locations to get relevant results. Most website speed test tools offers different locations to test. You may want to test from a location from the majority of users are coming from. In addition, you should test from a location closer to your location and also from a location that is quite far. This will give you a better picture on any latency issues, and will also help you understand the effectiveness of your CDN.

We hope these tools will help you run website speed tests easily. Feel free to leave us a comment if you have a query.
