What is a 'click' in the context of online advertising?

In the context of online advertising, a 'click' refers specifically to the action taken by a user when they click on an advertisement. This action is a critical interaction that signifies interest in the ad content or the offering being presented.

When a user clicks on an ad, it typically redirects them to a landing page or a website associated with the advertisement, effectively tracking engagement with the ad. This measurement of engagement is pivotal for advertisers as it helps them evaluate the performance of their campaigns, understand user behavior, and optimize their marketing strategies.

While other elements such as measurement of user impressions, payment models, and tracking ad views are important in the advertising ecosystem, they do not define what a 'click' is. Therefore, the definition focusing on the user's action of engaging with the ad captures the essence of what a 'click' represents in digital advertising.
