Chitika Google Rankings Study 

Did you know that a website that ranks #1 on Google receives more traffic than the websites on positions #2 to #4 combined? Chitika, an advertising network that I used to use back in 2006, recently did a study on the effect of Google rankings on organic traffic, which re-affirms past findings about heat maps, etc.

Here’s a breakdown of the percentage of traffic received by the top 10 spots respectively, based on a sample of 8 million impressions:
#1 - 34.4%
#2 - 17.0%
#3 - 11.4%
#4 - 7.8%
#5 - 6.2%
#6 - 5.1%
#7 - 4.0%
#8 - 3.5%
#9 - 2.9%
#10 - 2.7%
