Interesting article by Ben Hunt – author of Convert!, Save the Pixel, and also the Pro Web Design Course (which I am taking, but haven't reviewed yet).
There is a common theme in many books about SEO – 40% of the clicks go to the first ranking position, 11% to the second, and so on until by position 10 you can count about 99% of all clicks for a given search.
Ben took the data from Google Webmaster Tools for his top keywords and charted it. From his data it is pretty clear that you not only have to get a good ranking – you need a good text snippet and title that convinces the user that your page is what he needs.
An important conclusion is that you need to have good titles and meta descriptions. While viewing the video I realized that my blog didn't have meta descriptions (some themes seem to use excerpts, other don't).
I immediately added WPMU's DEV SEO, which seems to cover what I need and more.
I recommend that you look into your pages meta-descriptions, too…
