OK, I appreciate you have a valid viewpoint, but in tarring us all with the same brush I find your post offensive.
As somebody pointed out, we get ZILCH information from Google on coversions etc etc.
I've worked hard on making my site a quality site. It's no 3 on the main keyword on most search engines. I get a lot of traffic coming to the site, and judging by the paths they take through it, clearly are seriously interested in the topic. I am a member of quality assurance schemes such as "Health on the Net". I have absolutely top quality sites and articles (such as articles published in the British Medical Journal) linking to my site and providing traffic. I've even had a respected figure in the field wanting to lift one of the articles I have researched and written for publication it in his new book.
My adverts are well targetted, and judging by the high CTR people have a serious interest in their services.
I have the quality articles, I have the quality links, I have a lot of serious visitors who click through.
And this is all BEFORE I added adsense just over a year ago.
What are you telling me? My site isn't advertiser freindly? Surely the only things I can do is keep up the quality, and in turn that provides the advertisers what they want?
You came up with the thread - how about some answers?
