I Have Earnings . But No Clicks?

[internetheaven]

Sites that should have clicked ads are not being clicked any more. But, the earnings keep going up by £0.01 at the rate I would normally expect clicks to.

e.g. for a site where I would expect a 0.5% CTR, the visitors show 3612, the clicks show 0 (where we would expect 18) but the earnings are £0.18

Anyone seen this before?

Yep, all the time. CPM ads. Someone has targeted your site for placement ads - i.e. they're bidding per thousand pageviews, rather than per click. If you get a lot of traffic, they add up.
