It seems that SEO experiments still worth the time. “NoIndex, Follow” is The big secret of Google’s Panda Update! I don’t have time to make a detailed explanation of this.
A SEO expert that is really good will make a detailed analyse of my website’s pages and he may or may not understand the big SEO secret that will remove the effects of Panda update!
After I found this I managed to remove the Panda effects of 3 eCommerce websites that dropped form SERPs last year.
Good Luck to you all!
