Thanks for the response, the amount of links really varies per page but could be around 170 in some cases and some of these links are external as well as internal. The site itself has plenty of content so it isn't a case of us trying to cheat any sort of Google guideline but to try and keep number of page links down.

Basically I wanted to know if we would be hurt by using javascript link instead of the usual href="#"

I am currently working a site re-design and we are looking at if href="#" and href="javascript.void()" have an impact on the site? We were initially looking at getting the links per page down but I am thinking that rel=nofollow is the best method for this. Anyone had any experience with this? Thanks in advanced
