How many time the free results Click Thrue Rate it's higher then AdWords Click Thrue Rate?! Asking this questions because so many people are paying so much for getting #1 in the free results. let's say that some seo experts are asking montly 1000-5000% or even 20 000% more money then it will cost me to advertise with AdWords
I do organic SEO results and I also manage the adword campaign. This allows me the opportunity to have two links on the front page so I double my exposure. I actually buy my domain name and several variations in adwords and notice a 11% CTR for my paid listings. It is worth a few extra cents not to loose someone when they are looking for YOU exactly.
You can't figure out CTR for organic listings - there's no impression reporting. Without knowing the number of impressions you can't calculate a CTR.
