Conversion Tracking is the setup that records valuable user actions after ad clicks or other marketing interactions.
It matters because paid search can spend budget quickly. Knowing this term helps teams control intent, targeting, bidding, creative, conversion tracking, and lead quality instead of optimizing for surface-level clicks.
Example
A contractor records a conversion when a quote request is successfully submitted, not merely when someone opens the form. Testing that action after an ad visit helps verify the connection between the campaign and the inquiry before reported conversions inform bidding decisions.
