What metric allows you to track how many times an individual has seen your content?

The metric that allows you to track how many times an individual has seen your content is impressions. Impressions count the total number of times your content is displayed, regardless of whether it was clicked or interacted with by users. This means that if a single user sees the same piece of content multiple times, each of those views contributes to the total impressions.

In contrast, reach measures the total number of unique users who have seen your content, which does not account for multiple views by the same individual. Engagement rate indicates interactions such as likes, shares, and comments, while conversion rate tracks completed actions such as purchases or sign-ups attributable to your content. Therefore, impressions are specifically useful for assessing the frequency of exposure to your content.
