It would be considered the same as linking the website. However, you can say that you use a website as a resource for your writing; if someone approaches you about that website in private, providing a link in response (via PMs) would not be considered advertisement.
I noticed you provided a link to a website with the url superheronation.com, and I would like to point out that our forum rules forbid advertisement to websites that we are not affiliated with. I have already edited the link out.
