Today on SearchEngineLand, I caught this graphic:

Click-Through Statistics

Despite my great trust in all things Danny Sullivan (yes, I know this technically comes via Elliance), I've got to say that I find this somewhat hard to believe. Do 28% of all searchers really click on results within page 2 or 3? In my experience, the traffic difference from position #1 to position #11 is far more disparate - something closer to 1/100th of the visits.

I'd be extremely curious to see truly accurate and industry-wide data on all of the following:

  • Average CTR on positions #1-#40 (at each of the major engines)
  • Average CTR on ad listings vs. organic listings (at each of the major engines)
  • Comparison of visitor behaviors from paid search vs. organic search
  • Comparison of visitor behaviors from top 3 listings vs. bottom 7-30 listings
  • Percentage of CTR on onebox and other vertical-style results
  • Percentage of traffic driven by each of the 4 major search engines (I'm somewhat suspicious of ComScore's numbers - Google lost share at Microsoft's expense?)

If anyone has this data, or links that point to valuable sources, please do share. I suspect that my limited experience in a few hundred SERPs is no match for truly robust, industry-wide data.

BTW - Loving the vacation. I have my heart set on this place for the wedding, but Mystery Guest remains open-minded.
