A lot of people say it is important to carefully choose external links for your site. I know linking out to link farms and unrelated sites is NOT good for my SEO. But, does linking to high-quality, related sites help my SEO? Or keep it the same? Or does it hurt? For example, if I link out to a related article on Wikipedia with a high PR.... would it help my SEO, hurt my SEO, or neither? Thanks!
Google does not mind you linking to high authoritative sites, I would keep your resouces/links page to under 30 links out though.
Link to everything that is useful to your visitors Use nofollow for the sites you don't want to vote for... don't think linking high authoritative sites will help you alot
