Conversion Rate

Conversion rate (often CVR) is the fraction of clicks that turn into conversions:

conversion rate = conversions ÷ clicks

A source that sends 1,000 clicks and produces 30 conversions has a 3% conversion rate. It's one of the most quoted numbers in affiliate marketing because it isolates quality: how good a source, offer, or landing page is at turning a visit into a payable action, independent of how much volume it has.

What conversion rate does and doesn't tell you

Conversion rate answers "how often do clicks convert?" — but not "how much is each conversion worth?" A source with a high conversion rate but tiny order values can earn less than a source with a lower rate and big orders. That's why experienced buyers pair it with EPC, which folds in order size. Conversion rate diagnoses the funnel; EPC diagnoses the money.

Conversions, not events

Conversion rate counts conversions — the payable outcomes (a sale, a funded account, a qualified lead). Intermediate events like a registration step are still tracked and can be paid, but they don't inflate the conversion count or the rate. Keeping the denominator (real clicks, excluding bots and duplicates) and the numerator (true conversions, excluding unattributed ones) clean is what makes the rate trustworthy.

A worked example

Two creatives on the same offer:

• Banner A: 5,000 clicks, 60 conversions → 1.2%
• Banner B: 2,000 clicks, 80 conversions → 4.0%

Banner B converts more than three times as efficiently. Even though Banner A drove more raw clicks, Banner B is doing the real work — so you'd shift budget toward it and investigate whether Banner A's traffic is low-intent or even fraudulent (a very low conversion rate on high volume is a classic fraud signal). Conversion rate is what surfaces that comparison at a glance.

How this works in LimeliJourney

In LimeliJourney, conversion rate is computed in reporting from the exact clicks and conversions in each view, with bot and duplicate clicks excluded from the denominator by default so the rate reflects real visits. Events never count toward it — only conversions do — so the number stays comparable across offers. Because you can break traffic down by affiliate, sub-ID, creative, geo, and device, you can find where a conversion rate is strong or collapsing rather than just knowing the program average. LimeliChat can surface the outliers on request — "which sources have the lowest conversion rate this month?"
