Why is there a discrepancy between the impression count in the Quality tab and the rest of the report while my campaign is running?

The impressions counts are updated asynchronously from the rest of the report, so you may experience small differences in the counts.

How did we do?

Why is my overall score not that bad when almost all my impressions are of low quality?

Will my viewability score of 0.0 affect the overall Quality score if I didn’t implement in-view tracking?
