Message wall impressions
See the number of message walls shown relative to the number of eligible visits by users with an ad blocker installed.
Total ad blocking visits: The number of visits by ad block users who are eligible to see the message wall. This metric is intended to show the number of page views that are eligible for the message wall.
If your messaging settings indicate that your wall be shown to less than 100% of eligible ad block users, then “Total walls shown” is always less than “Total ad blocking visits.”
Total walls shown: The number of times the message wall is shown to ad block users. This number includes all message wall types.
