Power of Tracking Code on Thank You Page

[Roman07]

Is there any way I can put a tracking code when redirecting the user to the offer. Example My FB Ad>User clicks>Views my landing page (I collected data)> User clicks button to learn more/ gets redirected to offer page (Can I put a tracking code here after user leaves my landing page/ like for Adwords tracking/FB Pixel). That way I can collect data and create look alike audiences. Has anyone done this before? Much thanks in
