Installing PageSpeed Insights

Running PageSpeed

PageSpeed generates its results based on the state of the page at the time you run the tool. To ensure the most accurate results, you should wait until the page finishes loading before running Page Speed. Otherwise, PageSpeed may not be able to fully analyze resources that haven't finished downloading.

To profile a page with PageSpeed, open the web page in Google Chrome. Then take the following actions:

  1. Select the Wrench menu at the top-right of your browser window, then select Tools -> Developer tools.

  2. In Chrome Developer Tools, click the PageSpeed tab to display the PageSpeed welcome screen.

  3. Navigate to the web page you want to analyze. Wait until the page finishes loading.
  4. Click Analyze. When the page is analyzed, PageSpeed displays the list of web performance best practices on the left-hand side, sorted by importance/priority for the page being analyzed.

  5. Click on any of the rules to see specific suggestions for improvement.

Understanding PageSpeed performance scores

For each rule, PageSpeed gives specific suggestions for improvement. PageSpeed also gives the page an overall PageSpeed score.

Understanding the PageSpeed Score

PageSpeed gives you a total numeric score. The numeric score indicates how much room for improvement there is for the current page. A high score indicates little room for improvement, while a lower score indicates more room for improvement.

Uninstalling PageSpeed

To uninstall PageSpeed:

  1. In Chrome, select the Wrench menu at the top-right of your browser window, then select Tools -> Extensions.
  2. In the window that appears, select PageSpeed and click Uninstall.
  3. Restart Chrome.
