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.
The purpose of click-through rates is to measure the ratio of clicks to impressions of an online ad or email marketing campaign.
Most commercial websites are designed to elicit some sort of action, whether it be to buy a book, read a news article, watch a music video, or search for a flight.
In contrast, it is easy to determine the click-through rate, which measures the proportion of visitors who clicked on an advertisement that redirected them to another page.
Forms of interaction with advertisements other than clicking are possible but rare; "click-through rate" is the most commonly used term to describe the efficacy of an advert.

These ads are usually in text format and may include additional links and information like phone numbers, addresses, and specific product pages.
