Hi,
is it possible to have compare to previous period option via AWQL?
For example, in a query like this:
select CampaignName, Clicks from CAMPAIGN_PERFORMANCE_REPORT
where Status = ACTIVE and Impressions > 0
during LAST_MONTH
I get Clicks for the given period. In AdWords GUI, I can turn on Compare mode and select Previous period (or same period last year or custom) and get clicks for comparison period.
I haven't found the same option in API.
Am I missing something or should I simply execute 2 queries, one for each time period?
Thanks,
sasha
