Although URLs play an important role for search engine optimization, they also play an important role in [social bookmarking](http://neothoughts.com/2006/08/15/urls-matter-in-social-bookmarking/). One of the most important factors to maximizing your exposure on [del.icio.us](http://del.icio.us) and other social bookmarking sites is the URL of a website.
there are currently 3 main listings on del.icio.us for Crazy Egg. The first listing is for http://www.crazyegg.com which has been bookmarked by 2034 people, the second is for http://crazyegg.com which has been bookmarked by 1202 people, and the third is for https://crazyegg.com which has been bookmarked by 349 people. Although they are all the same exact site del.icio.us treats them as three separate listings because one URL contains “www”, the second does not contain “www”, and the third contains “https”. So how did the URL of Crazy Egg affect its’ success on del.icio.us?
Crazy Egg has done very well on del.icio.us and those three listings have brought in well over 5000 visitors in the past few months. This has been possible because of the sheer number of people that bookmarked it which caused each listing to show up on the del.icio.us [homepage](http://del.icio.us) as well as the del.icio.us [popular page](http://del.icio.us/popular/), but never as the number 1 position on either of those pages. If the bookmarks were combined into 1 listing it would have increased the positioning to the top 1 or 2 spots instead of the top 3 which might have drove a couple thousand more visitors.
So if you want to maximize your traffic from social bookmarking sites such as del.icio.us, combine your URLs into one. Use redirects such as http://yourdomain.com to http://www.yourdomain.com, it will reduce the chance of having multiple listings on del.icio.us and maximize your potential traffic.
