If you have access to your website’s code, you can add the Facebook pixel yourself. Simply place the Facebook pixel base code (what you see when you create your pixel) on all pages of your website. Then add standard events to the pixel code on the special pages of your website, such as your add-to-cart page or your purchase page.

Many people need the help of a developer to complete this step. If that’s the case, simply email your Facebook pixel code to them, and they can easily add it to your site.
