We track donations made through an ad using the Facebook Pixel, which is installed on our website. We set up a custom conversion for each campaign so we can track exactly how many people donated through the ad to your particular campaign and the total amount donated.
More about the Facebook Pixel here.
For donations made through our newsletter and homepage banners, we use custom links to track which donations were made through those avenues.
We hope this helped and as always, if you have any questions, feel free to reach out to our marketing department by emailing marketing@launchgood.com and we will gladly assist you :)
