I'm using Google Adwords API with PHP for generating local reports. I've been reading the documentations but can't find any reference on how to get this value:
Unique Ad Impressions
Is this data available in the Google Adwords API at all? If yes, how can I get it? Currently the only available data regarding impressions is the one that counts all impression regardless whether it was served to a new unique user or not.
Also anyone knows the general percentage of unique ad impressions to total impressions? Example 50% of total impressions came from unique viewers, the other 50% are repeat viewers.
