Adsense Cost Per Click Depending on Time of Day

Because advertisers set a daily budget, it makes sense that...

I have noticed vastly different costs per click for Google ads in the course of one day. It makes sense because advertisers set a daily budget, so when the budget for some of the advertisers runs out for these keywords, the advertisers who still remain will pay less.

My question is: What time of the day is the daily budget reset? I have noticed that I tend to receive more per click later in the day, while in the early morning, the rates seem to be low. However, I got up very early this morning, and I had received only one click, at a very high rate.

If you could know when the rates are the highest, Kanoodle offers you the option of only showing up in their CCP database certain time of the day. At my current click-through rate, it would make sense for me to pay for visitors when the Google rate is high, but I would be loosing money when it's low.

Any advice?

My advice is to look at your total earnings only in deciding whether any advertising program works best for you. Whenever I try to determine trends in my EPC, my assumptions will be refuted the next day or the next week.

Don't forget that your customers may not all be in the same time zone.

I get a great CTR when the US is asleep and mostly Brits and Europeans are viewing the site.

If you read the Adwords documentation, you'll find that this is a rather unlikely reason. If an advertiser has set his daily budget so that his ad can only appear half as often as the targeted keyword is served, then that ad will only be shown every second time throughout the day.

The mechanism is based on statistics from previous days, so it can't always be accurate. This is the reason why some advertisers report that their limits are sometimes exceeded. If the excess impressions are more than 10% (I think), then Google will refund the additional costs. But it will not normally show an ad during the first half of the day and then drop it.

If you observe CPC variations throughout the day, then those are either caused by reporting delays, or the clicking behaviour of your visitors depends on the time of day.

I used Adwords as an experimentation a few months back, and I remember reading on Google that this daily budget is more of a monthly budget divided by 30 (or however many days are in the month). That is, while day 1 may exceed your daily budget, the sum of days 1 through 30 should not exceed your daily budget times 30.

So I think they try to average this out over the days in a month, not necessarily trying not to exceed the maximum on any particular day.
