Will the cost be changed after a couple of days?

[Brandon]

Hi, 

I've downloaded a set of account_performance_report of 574-050-3210 which is segmented by date from 2014/09/01 to 2014/09/30 in last year.

Today, I downloaded the same report with the same date range and found that the costs are different between each other(about 160 NTD).

Two of them were downloaded after the data is ready(After 3 a.m. UTC+8).

Is that because of the removal of invalid clicks?

If it is, then when is the best time to download the most precisely data from AdWords?

Thanks,

Brandon

Hello Brandon,

Yes, data can be adjusted for reasons like invalid clicks. The stats data is final 72 hours after the date.
