People it is not what it can do for you that will bring value. It helps your position because there is a relevant link on another site to your site.
If no one comes to the site who cares? The search engines catch the links and you win without regard to what Craig`s List is or is not. It is just good SEO. Do the freebie links when you can; not for money but for SEO.
Tony brings up one of my favortie pet peeves....Can we define a "Hit"?
A hit is when you go to a website and your computer loads the site. Each image on the site represents one "hit." so if there are 40 images on the home page, that is 40 hits.
We want to measure in visits or unique visitors, not "hits." It is a totally BS number so far as a web site owner is concerned.
