I'm trying to do my best to control the link juice from my home page to the most important category landing pages on my client's e-commerce site. I have a couple questions regarding how to NOT pass link juice to insignificant pages and how best to pass juice to my most important pages.
INSIGNIFICANT PAGES:
How do you tag links to not pass juice to unimportant pages. For example, my client has a "Contact" page off of there home page. Now we aren't trying to drive traffic to the contact page, so I'm worried about the link juice from the home page being passed to it. Would you tag the Contact link with a "no follow" tag, so it doesn't pass the juice, but then include it in a sitemap so it gets indexed? Are there best practices for this sort of stuff?
