This is an important thread in my view, and I hope it stays on topic.
My site has very very good rankings, but the click through rate is nowhere what it was say 3 years ago. The value of the clicks is lower also - much much less likely to have someone spend any time on the site.
The site has improved as well over the years, both in terms of content and things you can download.
Overall, I'd say the economic value to me of search has declined dramatically.
I'm not a professional SEO. However, I'd have though this has some major implications for search marketers.
