I just analyzed the new visits to one of my websites; this one.

I found that of the many thousands of new visitors who arrive at this site from my organic rankings on Google , Bing and Yahoo! 67.4% are landing on my blog posts!

Once these new visitors arrive at the site they spend 3 minutes and 48 seconds looking around. Of course this results in many new subscribers to my blog and a percentage of those subscribers ultimately turn into customers.

By consistently adding fresh valuable content to your website you are demonstrating to Google that your website deserves top rankings.

I also set up goals in my Google Analytics, this allows me to see the number of subscribers each post produces.  Here is one of the posts that consistently converts new visitors into subscribers- http://imgmembers.com/how-much-should-i-pay-for-seo/
