What type of link should I usef or view cart, login and register

[WebstaurantStore.com]

Hello,

What is the best practice for links appearing on every page of your site pointing to shopping cart, login, registration, etc. pages?  Basically what is the best format for links in your site template that point to pages you do not need to rank or possibly even be indexed?

no-follow, iframe, regular?

Thanks.

I use something like this for shopping links....

Not saying that it is good or best or bad... just sayin'.

If you opt to go with links, setting rel="nofollow" won't hurt a bit... no need for google to be checking out the registration form page

just no-follow the link. That is one of the two uses of the no-follow attribute. The other is for content that you cannot vouch for.
