So I've been reading up on SEO lately and been trying to find answers to this question. In short I've read that it doesn't have any negative effects, but the only way it's improves SEO if it uses 301 redirects.
But my main question is if it's still the same for using short URL's that are a different domain?
Our domain is thetradehub.net but we trhub.net as a short URL for when users copy blog posts, or profile links.
