Finding out if a lead came from Google Ads/Facebook is a two step process.
**Getting information from Google/Facebook to your landing page**. Google and Facebook use URL parameters to pass information to your landing pages. You can decide what parameters you want when setting up tracking.
**Getting that information from your website to your inbox or CRM.** You extract the keys and values for the URL parameters, save them to a cookie/session/hidden form field and then include them with the form submission when the person uses the booking form.
