Conversion rate for Google vs. Search Network

[rustyzipper]

After a couple of months of reviewing our logs & concerns over the quality of some of the Search Network traffic, we decided to test for 2 months running our ads on Google only.

Our conversion rates appear to be about 35-40% higher on Google only than on Google + Search Network.

This is only testing a 9 week period.

I'm curious if anyone else has compared conversion rates on Google vs. Google+Search Network & what the results were?

What do you mean by "Search Network"? Do you mean "Search Network" vs. "Content Network" or do You mean "Adwords Search Network" vs. "Google Natural Results" or do you mean "Adwords" vs. "Google Natural Results"?

That is interesting, for campaigns I have that are very marginal or break even I may try converting to google only, if not so lazy ;)
