How Do Website Speed Testing Tools Work?

After realizing how important it is to have a speedy website, then you might want to try running a website speed test. But, how exactly does this tool help your website?

Website speed testing tools are measuring your website performance metrics and grade them. If the metrics perform badly then it results in a poor grade too. The followings are the most common metrics to watch out for:

  • Resources that load too long

Resources including fonts, images, plugins, and JS files can slow down your website’s loading.

  • Time to first byte (TTB) and First meaningful paint (FMP)

The two metrics that are really important for loading page time are TTB and FMP. They will show you when your website starts loading and the second your website starts displaying information.

  • Load time, number of requests, and page sizes

Load time, the number of requests, and page sizes can dramatically increase the load time of your website. Therefore, you need to pay attention to these metrics.

  • HTTP headers

HTTP headers are how servers communicate with the server by sending information back and forth via a request or response. By testing this, you can make sure you are getting and sending the right message between the two. Moreover, this is useful when you are trying to debug different errors you might have.

  • Content Delivery Network (CDN)

Enabling CDN on your website will significantly improve your website’s speed. Therefore, it is necessary to set up CDN to fasten your loading page time.

  • Page Caching

Caching is the process of storing resources from one request and reusing those resources for subsequent requests. It reduces the amount of work required to generate a page view. Therefore, enabling cache can help your website to load faster.
