Absolute effect
The measured difference in the original unit between an exposed group and a baseline, such as twenty additional approved sales.
#Affiliate marketing A–Z
Plain-English definitions for affiliate partnerships, advertising, tracking, creator commerce and publisher monetisation. The vocabulary can sound more complicated than the underlying ideas, so every definition focuses first on what the term means in ordinary day-to-day work.
Use the search when you meet an unfamiliar expression in a contract, report or platform demonstration. Then return to the surrounding decision: who is paid, which event is measured, what data is used and which person carries the risk when the expected outcome does not happen.

Put the terms to work
Knowing the words makes it easier to compare offers, question a report and explain a decision to colleagues or partners. The next step is to connect those definitions to a real audience, budget and operating process.
Use the same period, currency and conversion definition. These figures are illustrative assumptions, not an earnings promise.
| Metric | Formula | Educational example |
|---|---|---|
| CTR | 100 × clicks / views | 1 500 / 10 000 = 15 % |
| CVR | 100 × orders / clicks | 45 / 1 500 = 3 % |
| Approval rate | 100 × approved / recorded | 90 / 100 = 90 % |
| EPC | approved commission / clicks | 486 € / 1 500 = 0.324 € |
| RPM | 1 000 × revenue / visits | 1 000 × 486 € / 10 000 = 48.60 € |
From 10,000 visits, a 15% offer click rate produces 1,500 clicks. At a 3% order rate, 45 orders are recorded. With 90% approval and €12 per approved order, expected commission is €486 before costs. An expectation of 40.5 orders is a model average, not an actual order count.
