I was building backlinks for my new site today and I asked myself why should Google consider these backlinks if no traffic is coming to my site through them? This is a very easy way for Google to make the difference between natural backlinks and SEO backlinks. So I'm blasting tons of content and backlinks but there is something missing in the picture. Real visitors with Google Toolbar, Chrome (or whatever) clicking on my backlinks and staying as long as possible on my site! Your thoughts?
