What is Click-Through Rate (CTR)?

The percentage of people who click on an affiliate link compared to the total number who see it. Calculated by dividing clicks by impressions. A higher CTR suggests more compelling content or better link placement.

Conversion Rate

The percentage of visitors who complete a desired action after clicking an affiliate link. Calculated by dividing the number of conversions by the total number of clicks. A higher conversion rate indicates more effective marketing or a more compelling offer.

Earnings Per Click (EPC)

A metric that measures the average earnings generated per click on an affiliate link. Calculated by dividing total affiliate earnings by total clicks. EPC helps affiliates compare the profitability of different programs and campaigns.

Impressions

The number of times an affiliate link, banner, or piece of content is displayed to users. Impressions measure visibility but not engagement — clicks and conversions are needed to determine actual performance.
