Google gives importance to the behavior of the users which make a search on his search engine.
A web site which will be chosen most of the time further to a keyword hit on Google, will be better positioned, this is a way of improving your SEO.
I am going to ask real users with unique IPs ( no spam ) to type a keyword which you will have chosen and to click only the search result where appears your web site.
-Duration of every visit: between 13 and 15 seconds of connection
- Option : country selection for IPs of requests / extra fast option not applicable / google.com routing preserved
