Before you begin, please make sure that your Facebook pixel is installed and Active. Please also make sure that you've added standard events to your code on all of the pages that you want to track and optimise for actions on. You may also use custom conversions.

The Facebook pixel can be attached to ads to perform two functions:

1. Conversion optimisation: It can be used to optimise your ad for conversions (e.g. It'll tell Facebook to deliver your ad to people who are most likely to reach the checkout page of your website).
2. Conversion tracking: It can show you how successful your ad is by reporting on conversion events (e.g. registrations, checkouts) on your website which happened as a direct result of your ad. You can see this info in your reports.

To optimise for conversions and report on the success of your ad, you'll have to select your pixel when setting up your campaign. You can do this in ad creation and Power Editor. If you optimise for conversions with your Facebook pixel, we'll automatically track all of the actions on the web pages that you've placed it on.

Create a website conversions ad

When creating your campaign, choose Website Conversions as your objective. You'll then have to enter your website's URL and select the type of conversion you want to optimise for. For example, if you'd like to optimise for sales, choose Purchase as your conversion event.

After your campaign runs for a few hours, you'll be able to check your conversion results and see your website traffic data.
