Goal: Optimize your current WordPress setup and content for faster page load times.
Ideal Outcome: Your users experience faster page load times and your server resources are more efficiently used, while your website still looks exactly the same to the end-user.
Prerequisites or requirements: This exact process only applies to WordPress.org sites.
Why this is important: As page load time goes from one second to five seconds, the probability of bounce increases by 90%. Without requiring a server upgrade, you can optimize your WordPress website so that it loads faster, therefore retaining more of your users.
Where this is done: On your WordPress Admin Panel, on Pingdom.com, on Google Chrome.
When this is done: Whenever there are pages that can still be further optimized. Whenever your page load times are too high.
Who does this: The person responsible for Website Management, or a Web Developer.

- **Note: While this procedure is not likely to affect your website’s behavior and functionality there is a small chance it might be incompatible with your current server settings, current theme, or plugins and cause your website to be partially or completely unavailable.
- Checking your website performance
Using an external tool:
- **Note: Using an external tool like Pingdom allows you to test your website by using a third-party server on a designated part of the world, ruling out the possibility that the cause for your website’s poor performance might be due to your current poor internet connection, device, or location in the world.
- Using Pingdom:
- On your browser head over to https://tools.pingdom.com/;
- Insert the page that you would like to test on the URL field → Select the location that is closer to where you target audience is → Click “Start Test”;
- **Note: If you don’t know which pages to test, they should be the most important pages on your funnel. (E.g: Homepage, Sales pages, Checkout, etc)
- You will get a summary table with some key metrics you are looking for on the top:
- Performance grade: Your Google PageSpeed score. The higher the better.
- Page size: The total size of your page, the amount of data a user would have to download if they requested your page. The lower the better.
- Load time: The time (in seconds) it takes for your page to load under great network conditions. Bear in mind that depending on how your page is setup this result may appear to be slightly lower than what it really is. The lower the better.
