Test current speed

Before you begin using APO, we recommend testing your current site speed. Your site speed results give your website a letter grade and performance rating.

  1. Visit GTmetrix.
  2. In the text field, enter your website’s URL.
  3. Click Test your site.

After the test runs, you can view your site’s grade, performance rating, and other performance metrics.
