In Google Ads, "interactions" refer to the main types of actions users take with your various ad formats. Interactions can vary based on the campaign goals and ad types you are using. For instance, interactions could be clicks on text ads, views of video ads, swipes on carousel ads, or calls from call extensions. The specific type of interaction depends largely on the ad format and the user interface.
Google Ads tracks these interactions to provide insights into how users are engaging with your ads. This data helps you understand which aspects of your ad campaigns are effective and which might need adjustments. It also plays a crucial role in campaign optimization, allowing advertisers to refine targeting, messaging, and overall ad strategy based on actual user behavior.
In terms of billing, Google Ads often charges advertisers based on these interactions, whether it’s per click, per thousand impressions, or per engagement, aligning the cost with the value derived from user actions. This approach ensures that spending correlates directly with the level of user engagement, maximizing ROI for ad spend.
