I have a visitor tracking system in place for my websites. I have gleaned all sorts of data from external referring pages to how many colors their monitor will display to whether they're drinking a carbonated soda (not really, but it does seem to record just about everything imaginable). Except one thing...whether their visit to my sites are because of a bookmark. Here's a basic question: Is it possible (using Javascript for instance) to detect (and record to a DB) when one of my web pages has been manually bookmarked through the browser's toolbar? This struck me as being yet another way to measure the popularity of my sites as a whole, not to mention which pages are being viewed as informative enough to plop in a placeholder. This came about because my stats tell me that the majority of visits to many pages are via direct link or bookmark (grouped into one category). I'd like to break this down further by eliminating links to these pages generated by natural links on other sources.
