Everybody knows that getting on the number one position in any of the search engines, and especially the big G, has its rewards in the form of lots and lots of (if you’ve done your keyword research correctly) very valuable and free targeted traffic.
Whats frustrating to most though is how much traffic? Keyword estimation tools such as Keyword Discovery, and Wordtrackergive you a rough guesstimate of how much traffic a certain keyword generates overall but does not tell you how that figure is broken down.
Luckily, there are a few studies out there that have estimated the click through rates on the various positions in the search engines (mainly Google). SEOmoz, estimates clickthrough rates for SERPS as follows:
Position 1 receives 42.1% of the clicks
Position 2 receives 11.9%
Position 3 receives 8.5%
Position 4 receives 6.1%
Position 5 receives 4.9%
Position 6 receives 4.1%
Position 7 receives 3.4%
Position 8 receives 3.0%
Position 9 receives 2.8%
Position 10 receives 3.0%
While another study conducted by a group of students at New York’s Cornell University predicts the following clickthrough rates in the Google SERPS (search engine results pages):
-
Position 1 receives 56.36% of the clicks
-
Position 2 receives 13.45%
-
Position 3 receives 9.82%
-
Position 4 receives 4.00%
-
Position 5 receives 4.73%
-
Position 6 receives 3.27%
-
Position 7 receives 0.36%
-
Position 8 receives 2.91%
-
Position 9 receives 1.45%
-
Position 10 receives 2.55%
As you can see, the above SERP clickthrough estimates show that ranking above the fold -and especially in the top 3 positions- generates between 60 to 80% of all possible clickthroughs for any keyword.
Lesson to take from this post..make sure you (or your seo agency) make efforts to rank above the fold (top 3 serp positions), anything less is just not good enough!
