I use a custom short domain which is a subdomain of my main domain, for sharing my website.
I would like to know if this is legally ok to use a custom short domain for sharing third-party links, also SEO-wise, could it have any negative effect on my website? because I am using my own subdomain to share third-party contents?
On my website and my social profiles, I regularly share direct links to other websites, without having a page or article about them on my website, which means I will not get much from those links, only my domain will get some attention.
Websites usually use their custom short domains ONLY for sharing contents of their main domain.
