We have confirmed reports of Google beta testing a new AdWords budgeting option. The budgeting option is named "Timeframe" and gives advertisers the ability to budget by month or by day. The help document explains this a bit better.
The difference between monthly and daily is described as:
With a daily budget, lower traffic days may mean that your ads receive fewer impressions and have some budget leftover. We don't use this leftover budget, but we do attempt to compensate for the loss in traffic by serving impressions up to 20% over the daily budget on high traffic days. However, some high traffic days require budget flexibility beyond this amount.
With a monthly budget, we'll adjust your budget automatically each day to meet traffic demand while still respecting your budget for the calendar month. For example, if your ads often receive less traffic on non-business days during a month, we'll apply your unused budget to remaining business days to take traffic fluctuations into account.
AdWordsAdvisor, the official Google representative, at WebmasterWorld confirmed the new budgeting option, saying:
Sounds as if the one account has been made a part of a limited beta test, ppcbuyers. Not much I can add beyond that. :)
Are you seeing the option? Will you be giving it a try? Let us know.
