Welcome to the Q&A Forum

Hi Keri, thank you very much for your response. I already have cheap, free, inexpensive and variations of such negatives, but the link you mentioned has some really useful information. Thanks a bunch!

No, nav and footer links do not suck juice that you could otherwise redirect somewhere else via 'nofollow'. Yes, juice is split evenly between all outgoing links on a page. So if you reduce the number of links (by deleting them, not just making them 'nofollow') then you can increase the juice passed to the remaining links on the page. This is why it's rarely a good idea to have a page with tons of links on it; each one is going to only pass a little bit of juice. Having said that, nav and footer links can be very helpful for the humans who visit your site, so you don't want to strip them all away and make your site hard to use. But If you have dozens of barely-useful links jammed into your footer then you should probably nuke those. Design your site for humans. And trust that Google will do something reasonable with the link juice flowing around your site.
