Quite possibly that will be zero clicks and the RPM is because of CPM type ads.

I would have thought 0.2 cents suggests RPM 2 euros not RPM 20 euros but perhaps my sums are wrong.

It is also likely the reporting is out of step: it would be unusual to have 1 page view with 7 ad impressions.

are people able to buy 1 cent clicks in adwords?

IIRC the smallest individual click that I have identified on my sites is GBP0.05. CPM ads seems to be the most likely explanation to me.

0.1 or 1 penny clicks is not uncommon.

Reminds me of the days of "It takes pennies to make nickels, nickels make dimes and so forth"

There used to be a lot of discussions here by people wishing they could specify a minimum click amount they would accept.

My response is and was always "Go ahead, I'll take all the cheap clicks"

Imagine if word spread that you get buy AdWords clicks for a penny each. What a huge number of new advertisers that would bring. Let 'em in.

The size of the pie hasn't changed. The number of slices has, however, increased. Some will get a bigger slice because they ARE bigger. We live in interesting times.

Me too, I never understood the people who seemed to think that a single click of a pound was worth more than 101 penny clicks.

Yes, they can, in both the display network and in search. It's not common, but it can happen if conditions are exactly right. The biggest factor is having an ad that gets a significantly better clickthrough rate than competitors in the space.

some time ago, here on webmasterworld, someone mentioned that they made a page with no advertisements on it, and was able to send 1 cent clicks to it.

I wonder how much the domain name affects clickthrough rate for new websites that are not recognized.
example: made-up brandable domain, compared to an on-topic domain (like widgetstore.tld)
