Some Tips When Using Page Speed and Performance Tools.

As you have seen, there are many speed and performance tools. Which you can use to keep track of your website.

Before you dive in and use them. I have some recommendations for using performance tools for page speed and such.

  1. When using testers that ask you to set an area. Set the area closest to your average customer’s location.
  2. Different instruments will provide different sets of scores. Most of the tools are based on the native Google open source PageSpeed ​​API.

Scoring methods will vary from tool to tool. There are many different factors that can cause data to vary. Including network variation, device type, location of third party assets, the way the page was designed to load. (eg asynchronous loading). So be aware that your own site may report differences in scoring from each specific tool.
This is the reason why Google is moving towards fully loading from time to time. Which should bring more stability in scoring.

  1. Align with your development team about which performance metrics are most important.

When your dev team will have similar performance metrics and goals in mind. So they’ll be able to prioritize changes to your site that will increase page speed (and boost user experience).
