Which type(s) of conversions measure when customers see but don't interact with an ad before later purchasing a product?

View-through conversions measure cases where a user sees an ad, does not interact with it, and then later completes a conversion. In Google Ads, this metric is especially important for Display because it captures the value of impression-based influence that is not reflected in click-based reporting. A click is not required for this conversion type to be counted. That is why this is the only conversion type that matches a purchase happening after ad exposure without ad interaction
