This article will provide information on the main performance testing tools such as GTMetrix, and Google PageSpeed Insights.
Additionally, how to properly test your website and what to look for when viewing the results from the analysis.
How do I test my website properly?
First, you need to make sure to test the website properly before viewing or analyzing the results. The most important thing connected to testing your website is its correct URL. In other words, the proper URL with which your site loads in the browser.
The correct website URL would differ depending on whether or not it loads through HTTP/S and if it’s loading through “www” or “non-www” versions.
The next speed tool is GTMetrix and it is well-known in the WordPress community as one of the most used when testing for performance and determinating issues.
The test is pretty straightforward and you just need to input the name of your website (1) and choose “Test your site” (2):
After the test, you get a generated report from GTMetrix that will contain an overall summary of the website’s performance and Waterfall which would include all resources in a list.
The most important parts of the results are connected to the Summary/Performance/Waterfall sections.
The Summary section allows you to view the main results such as TTFB (Time to First Byte) (1), and fully loaded time (2), including visualization by rendering different parts of the tested page:
The Performance section allows you to view the main indexations and results from the testing application:
The results that are displayed are mostly related to highly technical performance metrics. More important things that you can focus on are the TTFB and Fully Loaded Time.
The third and most important section for GTMetrix is Waterfall. It contains a list of all resources loaded from the site – external and internal.
Viewing the section will give you a more broad perspective to determine which resources take more time to load and which need to be removed to better the performance:
Additionally, there is an article that will help you read and analyze the Waterfall section better here.
Google PageSpeed Insights.
The last speed tool is PageSpeed Insights. It allows you to analyze both Mobile and Desktop versions of your website.
The test itself is straightforward. You simply need to input your Website URL (1) and choose to Analyze (2) it:
You can choose between different results depending on if you want to view the Mobile or Desktop performance:
The speed tool does not provide much information or a Waterfall similar to GTMetrix that would help you analyze the resources on your website.
You can view the main results and metrics when scrolling down the page:
Most of these parameters can get better but you will need to hire an actual developer to make the needed changes on your website.
