Thanks, Robert. My question is more of a technical inquiry rather than a theoretical link-building question.
If two sites (follow)link to each other, clearly that does not offer any link juice. But if one site agrees to host a link as a no-follow strictly for visibility/leads/etc while the other partner hosts a follow link, would that provide an added benefit to the site with the follow link from an SEO perspective or do they still void each other out in the eyes of the algorithm?
