Clicks tell you how many people followed your link, but not what they did afterward. Conversion Tracking closes that gap: when you enable it on a link, we attach a hidden tracking reference to the destination URL.
You then add a small snippet of code to your website (we generate it for you) that reports back an event like "signup" or "purchase" whenever it happens. That event gets matched back to the original short link, so you can see exactly which links are driving real results, not just traffic.
