# Conversion Mapping

> The per-source rules that translate a conversion source's raw events into standardized conversions — so differently named events from different sources mean the same thing.

**Conversion mapping** is the set of per-source rules that translate a [conversion source](/glossary/conversion-source)'s raw events into standardized conversions. Different sources name the same outcome differently; conversion mapping is how one "sale" from anywhere becomes the same `Purchase` everywhere downstream.

## Per-persona meaning

- **Affiliate marketer:** the rule that turns each network's own name (`Sale`, `Online Sale`) into one standard `Purchase`.
- **eCommerce marketer:** the rule that reads a store's order and cart events as `Purchase`, `AddToCart`, and so on.
- **Lead-gen marketer:** the rule that interprets CRM stages (booked, qualified, won) as `Lead`, `Schedule`, or `Purchase`.
- **Business owner:** how AnyTrack decides what each incoming signal "counts as".

## Do not confuse with

- [Event Mapping](/glossary/event-mapping) — conversion mapping is *inbound* (interpret a source's events into a standard conversion); event mapping is *outbound* (send a conversion to each ad platform). This is the defining pair.
- [Conversion Source](/glossary/conversion-source) — the source is *where* conversions arrive; the mapping is the *rule* applied to it.

## In AnyTrack

Each conversion source has its own conversion mapping. An affiliate marketer connecting ClickBank, Impact, and Awin gets three differently named conversions — ClickBank `Sale`, Impact `Online Sale`, Awin `Purchase` — and conversion mapping normalizes all three into a single standard `Purchase`. That unified conversion is then sent outbound by [Event Mapping](/glossary/event-mapping).
