Yahoo and the importance of tracking visitors

In my experience, improving your Search Engine Results Page position is more difficult and takes longer on Google than it does on Yahoo. Google is important, much more important than Yahoo, but it can be nice to see some early results on Yahoo so that you know you're doing something right! I think this is a good time to stress the importance of tracking visits to your website. If you have functionality on your website that will track the page that a visitor came from before they arrived on your website then you can guage the success of your optimisation much more effectively. Tracking the amount of pages a visitor viewed and whether or not they filled out a form, made a purchase etc. gives you the opportunity to draw even more conclusions.
