– Google has always advised advertisers that the daily budgeting feature gives advertisers recourse only if the limit they exceed is the daily budget times 30, over the course of a month.

– More recently Google seems to have released a feature allowing advertisers to set a monthly limit. Perhaps this is in response to complaints and threats of lawsuits over the past couple of years.

They may prove to be liable in this case, but going forward it looks like they’ll make the necessary adjustments to avoid future problems.

The budgeting features are difficult for some advertisers to grasp, like many features “hacked out” by Yahoo and Google in this very new industry.
