--- title: "What is Custom Conversion?" url: https://fibr.ai/glossary/custom-conversion description: "Custom conversions track user-defined actions that matter to businesses, helping evaluate success based on intent, optimize retargeting, and maintain accuracy." last_updated: 2026-05-05T11:56:19.380236+00:00 --- A custom conversion is a user-defined goal in analytics or advertising platforms used to measure specific actions that matter to a business. It goes beyond standard events like page views by tracking deeper behaviors such as form completions, demo bookings, video milestones, or trial activation. For instance, a B2B SaaS company might mark “Request Demo” or “Finish Onboarding Step 3” as custom conversions to align measurement with revenue outcomes. This lets marketers evaluate success based on meaningful user intent, not general traffic spikes. Custom conversions also support better audience building and retargeting. Instead of optimizing ads for generic clicks, brands target users more likely to take high-value actions. As privacy tightening continues, first-party event setups and server-side tracking help maintain accuracy. ### Explore more Glossary terms ##### Customer Journey Mapping Customer Journey Mapping visualizes how customers move through stages like awareness, consideration, purchase, onboarding, and loyalty.
