href="#" and href="javascript.void()" links. Is there a difference SEO wise?

[clickermediainc]

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

How many links are on the page?

If the links are internal and there to help the users navigate then why not leave them as do follow? If there are so many links that you're concerned, it might be worth considering that there too many links, not just as far a Google is concerned but also form the users perpective.

Remember, using nofollow top sculpt Page Rank is against G's guidelines.

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="#"

All links consume link juice even nofollow links.
What happens to the link juice is the question, does href="#" just flow back to the same page, first thoughts are yes, but then if that is the case, you would be able to manipulate how much link juice flows out of other links but adding more. so I think they may waste link juice. JavaScript links use link juice and there is no guarantee that Google is able to pass that link juice on.

A lot of CMS use this type of links href="#" on a A tag then use the A tag for some other reason, such as a button to fire JavaScript. I believe that if you want a button use a button, if you want a JavaScript link then attach the event to a SPAN or DIV, use A tags only for real links and be sure you know what is happening to your link juice.
