Using the Web Campaign feature to pop up display cards to users. The impressions were growing steadily the first month and then have been dropping ever since. Went from 2000 events in August to 1000 in September, and most recent numbers have us a 143 for the month of October. When I look at the segments most have over 25,000 people in them so I'm wondering if something technical is causing the cool down in the numbers. Any insight would be helpful. Thanks!
