How do you fix NoFollowed Linking Root Domains?

[LoveGodorDieTryin]

Currently a site that I am helping with (Not the lead just a simpleton) has 71% Followed Linking Root Domains, and 29% NoFollowed Linking Root Domains. How would we fix this? (215 Followed Linking Domains and 302 total Linking Domains meaning that there are roughly 87 No Follow Linking Domains)

This is in comparison with a site that has 94% Followed and 6% No Followed Linking Root Domains. (18628 Followed Linking Domains and 19759 total Linking Domains meaning that there are roughly 1131 No Follow Linking Domains)
So Jake you are saying that having a 29% nofollow link may actually be a good thing?

I assume you are referring to the NoFollow tag made to discourage spam backlinkers.

Those stats seem to indicate the results of 2 different backlink generation strageties, you can't retroactively change the number of noFollow links, one just has to be more selective in future link building, NoFollow links are said to add to a site's overall authority and may bring direct visitors as well so they are not necessarily a problem.

I can just comment that 94% doFollow links may be too high a percentage which combined with other factors like too many anchor text links with the same keywords could earn a ranking penalty or "Unnatural backlink pattern" warning. Some SEOs recommend more than 10% of links be NoFollow, some don't even look at noFollow or page rank stats and just manually judge the quality of a page they may get a link from.
