Adwords performance and conversion rates

I often read complains about Google’s Adwords advertising program. We had our starting problems with Adwords as well, but the situation improved a lot in the past weeks. I’m not sure why, but we got much more Adwords traffic than before. And I’m pretty sure it’s not click-fraud from Google’s Adsense network, because our visitors often read multiple pages and download our trial or subscribe to our newsletter.

This is the first month we actually reached our Adwords budget and I’m quite happy about it. What’s more interesting is that we have better conversion rates from the Adsense network than from Google’s search engine. We are now trying to target some relevant blogs with Site Campaigns and observe the performance. Did anyone else see any changes in Adwords?
