In Google Ads, what is defined as a 'conversion'?

In Google Ads, a 'conversion' is specifically defined as a completed action that holds value for the advertiser, such as a sale, sign-up, or any other goal the advertiser aims to achieve through their advertising efforts. This definition reflects the ultimate purpose of advertising, which is to drive meaningful results that support a business or organization's objectives.

Tracking conversions allows advertisers to measure the effectiveness of their ad campaigns, enabling them to understand which ads or keywords are successfully leading to valuable actions. This data is crucial for optimizing campaigns to improve return on investment (ROI) and overall marketing strategies.

The other options relate to different aspects of user interaction with ads but do not capture the essence of what constitutes a conversion. A click on an ad indicates interest, an ad impression signifies visibility, and user engagement could encompass a variety of interactions that do not necessarily lead to the desired outcome of a conversion. Therefore, while all these interactions are important metrics, they do not define a conversion, which is specifically about achieving a valuable action for the advertiser.
