Digital marketing term
Conversion
A conversion is when a visitor who arrived via an online ad (or other channel) completes a desired action—such as a purchase, signup, or subscription.
Detailed explanation
In digital marketing, a conversion is the valued action you define for a campaign or site: purchase, lead, trial start, newsletter signup, and so on. Conversion-focused campaigns report how many of those actions you achieved.
Clear conversion definitions and accurate tracking (via GTM, pixels, and analytics) are prerequisites for optimizing CPA, ROAS, and CRO. Without them, creative and budget decisions rest on incomplete data.
