Conversion
A recorded outcome after a click — a purchase, a signup, a trial — reported back with the click identifier and usually an amount.

A conversion is the outcome you actually wanted, recorded and tied back to the click that produced it. It is defined as a named goal — purchase, signup, trial — and reported to the platform with the click identifier, an order reference and, when there is money involved, an amount.
Amounts are whole minimum units: cents, pence, kopecks. 4999, never 49.99. A value with a decimal point is refused with the field named rather than rounded, because a rounding rule invented inside a payment path is how revenue reports quietly stop matching invoices.
Two properties make the numbers trustworthy. The order reference deduplicates, so replaying a failed webhook produces one conversion marked as a repeat instead of two sales. And the verdict about traffic quality travels inside the identifier, so an order attributed to a data centre or a proxy is reported as its own segment rather than deleted or silently mixed in. Judge links by conversions, not by clicks: clicks measure the invitation, conversions measure the offer behind it.
