Pinterest uses several metrics to measure ad visibility in its Home Feed, providing advertisers with insights into how their ads are performing and how visible they are to users. Some key metrics include:

1. **Impressions:** Impressions measure the number of times an ad is displayed to users in their Home Feeds. It indicates the visibility of the ad and how many users have had the opportunity to see it.

2. **Reach:** Reach measures the total number of unique users who have seen an ad in their Home Feed. It provides insight into the breadth of the ad's visibility and the size of the audience reached.

3. **Engagement Rate:** Engagement rate measures the percentage of users who interact with an ad after seeing it in their Home Feed. Engagement actions can include clicks, saves, close-ups, comments, and other interactions with the ad.

4. **Click-Through Rate (CTR):** CTR measures the percentage of users who click on an ad after seeing it in their Home Feed. It indicates the effectiveness of the ad in driving user engagement and driving traffic to the advertiser's website or landing page.

5. **Save Rate:** Save rate measures the percentage of users who save an ad to one of their Pinterest boards after seeing it in their Home Feed. Saves indicate user interest and intent to revisit or explore the content further.

6. **Close-Up Rate:** Close-up rate measures the percentage of users who perform a close-up action on an ad, such as tapping on the Pin to view it in more detail. Close-ups indicate user engagement and interest in exploring the ad further.
