I'm working on the ecommerce rossanoferretti.com and I'm trying to improve the SEO. I'm in the first page for some specific key phrase that could potentially drive 500K users to the website, but the traffic doesn't increase at all. How it is possible? Here is the key phrase, potential monthly traffic, google page, link position
colour maintenance shampoo, 100K, page1, link 7 protective detangling spray, 120K, page1, link 2 shining oil, 320K, page1, link 4 colour maintenance conditioner, 50K, page1, link 1
Somebody can explain me why I have just only 200 visitors/day?
