I think it goes without saying that if you're ranking very high on Google, you don't need to do as much advertising for the same amount of traffic as compared to someone whose site is not ranking. This translates to less money spent and more profits.You bring a really important point of view. I am also interested in knowing how page ranking for instance, determines which website attracts more traffic and if this translates to more sales, in the long run. Can we then say that if a business ranks highly on Google, there'll be less advertising costs?
