I added this tracking last week - as a directory I want to be seen as a hub and this increased our "page views" to include outbound links from 2.2 to 5.0.
I was using the onmousedown click to log the click and my clickthroughs were lower than Google's. 12% lower - enough to be concerned. Any thoughts.
I am working to provide clear signals that my site different than a scraper site - and this seemed to be one way - increase the pages viewed and measure by Google Analytics and to show lots of outbound referrals.
