Thanks for the inquiry....
For two things:
1. The URL will be displayed on your comment. When visitors see your website address and find it interesting, they will visit your link and thus, generate traffic.
2. The URLs published on blog comments will serve as back inks to your site. The more back links you have, the better your ranking on search engine results. Search engines consider the number of back links of a site as one of their criteria in ranking pages.
Hope this helps....
