I just run a test campaign using placement ads on a popular social networking site and has suprising results. Lots of impressions and what appeared to be lots of clickthroughs. On visual examination of the raw server log I saw 1 REAL clickthrough for each 5 clickthroughs shown on the campaign summary.
Just wondered if anyone has similar problems with adwords placement ads.
Thanks.

Adwords is usually dead on with my reporting, and I buy very large volumes of traffic. I would consider the accuracy of your server logs a possible source of the issue if Adwords is reporting hundreds of clicks that you aren't seeing.
