What is an impression? An impression is when an ad is displayed on a webpage. An impression is not a guarantee that the ad is seen by the page visitor. It simply means that the ad is shown on screen. The higher the ad is placed on a webpage, the more likely it is viewed by the page visitor.
Now suppose you have a campaign and it generates about 10,000 impressions every day for the past 6 month. Now, out of no where your impressions drops sharply from 10,000 a day to 6,000 impressions a day. That’s a whopping 40% decrease from the previous norm! What does this mean? where do you start to look? is this good or bad?

- Check Ad Status. This is when you want to check the status of your ads. When your website goes down or when the landing page Final URL breaks down, the Ad will be disapproved. When all ads are disapproved, no impressions will be served at all.
- Check Campaign settings. The settings in your campaign, are they changed? did you or someone turn bid optimizer on? did you forget you scheduled ad to be only served during a certain time during the day? A tiny change in campaign setting can set off huge change in campaign performance. Even many advanced users forget about checking this part.
