Are there any percentage rules for nofollow/dofollow external links on a site? I had an SEO expert from this list advise me to install the Wordpress 'nofollow' all external links plug-in. I did, left it at that, then had problems with contributors to site wanting a 'dofollow' link for their efforts. Overriding the plug-in manually was impossible, so I left it not knowing what to do.
I've now deactivated the plug-in. All external, and internal, links on my site are 'dofollow'. I think this is much better than the advice of the "SEO expert" as it shows I trust my content/references, etc. which I do.
But now I am worried that I need SOME nofollow links for SEO purposes. Is that true? I can think of a few I can add manually rel=nofollow to but do I really need to? REALLY CONFUSED about this issue. My site is quality content, now 350 pages and will be continually growing, etc.
What should I do? Is there a percentage rule of sorts for nofollow dofollow on a site? Does Google mark as a red flag sites with all dofollow? Though that would be ridiculous as many simply do not know how to work with a 'nofollow' tag and all URLs are by default dofollow.
