Click-through rate (CTR) is the ratio of clicks on a specific link to the number of times a page, email, or advertisement is shown. It is commonly used to measure the success of an online advertising campaign for a particular website, as well as the effectiveness of email campaigns.

Cost per lead (CPL) is an online advertising pricing model in which advertisers pay for a defined lead, typically the contact information of a consumer who has expressed interest in the advertiser's product or service.
