Was reading some stuff about SEO a few minutes ago and one source stated that too many outlinks is bad for SEO.
The problem is; I outlink a lot.
All my content is usually sourced up by lots of scientific literature. (a few articles have as much as 150 outlinks to scientific literature).
My question is: Is this bad for SEO and if so, should I make the links NO-Follow?
Thanks you very much in advance,
