The official blog for information about the Google Ads, Google Ad Manager, Google Mobile Ads SDKs for AdMob and IMA SDKs, and other Google Advertising Platform developer tools.
But here is the really useful part: there is a handy feature that you can use to calculate relative dates by adding or subtracting days, weeks, months, or years:
Start date
End date
Last 7 days’ performance
today-6d
today
Last month’s performance
startOfMonth-1m
startOfMonth-1d
Previous six months
startOfMonth-6m
startOfMonth-1d
You can use up to two operations per date. Let’s say we need to compare last month with the same period last year. We would need two requests like these two requests with these start and end dates:
Start date
End date
Last month’s performance
startOfMonth-1m
startOfMonth-1d
Same month last year
startOfMonth-1m-1y
startOfMonth-1d-1y
If you want to try these out, we recommend using the APIs explorer. You’ll find it at the bottom of each method documentation page:
