Google Analytics has been at the forefront of website analytics, ever since it acquired Urchin Stats and made it free of charge. There have been various improvements over the years, but this addition is a good'un. You can view all sorts of statistics and charts about individual pages on your website - while you're browsing it!
The feature isn't just about convenience though; it also allows you to see which links people are clicking on most, and you can choose to ignore links below a selectable percentage of total clicks. You can also apply segments (and custom segments), to really get accurate with your analysis.
