I've never heard of any law or regulation that prevents you from linking to anything on your web site. It's your web site -- you decide the rules, aside from your host.

That said, you should bear in mind that logos and images are subject to copyright or other rights. The same is true for names -- talking about Coca Cola is different from talking about coca cola. Also, you should stay away from defamation. If you mention a web site in a true and realistic context, then you are just sharing information.

As for the Google ads I think you should review their terms and conditions.
