Impression shares after 1 Nov.
What would be the best, fastest and most usefull report/strategy to secure your impression share data , in a way you can easily use that data from the past, in the future .
Re: Impression shares after 1 Nov.
Assuming you still have access to that data (it was scheduled to be removed from the active database on Nov 3), run Ad Group level reports with the available Impression Share metrics--I usually run these for various time frames that might include year-to-date and month-by-month.
Save those--they will provide you with some benchmarking for the future.
Hope that helps!
