But when that domain is boosted up the results later - maybe up to 2nd spot - and you decide to skip over it and click on result no.3.
Clickthroughs are influenced by titles, metadescription, and even a lack of metadescription. If a result gets skipped the problem might be with those factors or it could simply be that position 1 and 2 have more compelling titles.
I use certain strategies to increase my clickthrough rates in the SERPs where I'm number three. In those cases clickthroughs are partially because my titles and descriptions are better than my competitors.
I don't deny that testing goes on. But I don't think it's measuring the quality of the site because there are too many other reasons for the results. Too many to draw accurate conclusions.
