If you'd like to target your Facebook ads to people who visit your site, the Facebook pixel is the way to go.
It requires an HTML code snippet to be placed in the source-code of your site. You can also add it to an E-goi landing page:
1) Head over to the Collect menu, click Sign-up pages and hit View all. Click the 3-line settings button of the landing page you want to add the pixel to and select Options.
2) Scroll down to Advanced options and click Facebook Pixel. Paste the pixel's ID and save your changes.
That's all there is to it! From then on, your E-goi landing page will include Facebook's remarketing pixel. Use the Facebook Pixel Helper tool to make sure the code is active and ready to track your visitors.
