Why does google adwords go over my daily spend limit & billing question.

Couple of questions on google, why does it sometimes go over your daily spend limit, for instance my limits set to £200 daily and sometimes it goes over, how come?

Also why is there sometimes a large gap between being billed, usually I get billed every few days but then there was a gap of 10 days and I got an enormous bill which totally threw me, any ideas please.

thanks.

I've only dabbled with Adwords, but I also couldn't understand why Google used to regularly go over my daily limit. The answer (I believe) is that it averages out you daily spend across a month, and the system allows it to spend up to 20% more that your daily allowance!

Adwords Help describes it as follows:

AdWords displays your ad as often as possible while staying within your daily budget. When the budget limit is reached, your ads will typically stop showing for that day.

However, on any single day, the AdWords system may deliver up to 20% more ads than your daily budget calls for. This helps make up for other days in which your daily budget is not reached. However, you will never be charged more than your average daily budget over the course of a month. For example: if your daily budget is $10 and the month has 30 days, you might be charged up to $12 on any single day but your monthly charges will never exceed $300.

Seems like we "the customer" have to spend our money when Google wants... nice job!

Thanks thats excellent, any ideas on the 2nd question why they suddenly stop billing every few day and then wack a great bill off my card 10 days later.

I've questioned Google directly about this when it allowed spending to go way over 20%. I got a refund and it has never happened since!

Sorry, can't help with the billing issue - I only ever got billed monthly and they certainly never missed that!
