An integral part of marketing any site whether it be general “real” information or some black hat ebook you are trying to sell is that you should market your site in the signature of your profile in website forums. A great example would be the huge Digital Point Webmaster Forums. People are always trying to hawk some product on there and it is a great way to get exposure to your site.

I remember promoting a White Hat site I sold recently. Early on in the SEO campaign (which by the way NEVER ENDS), I increased my backlink count by adding a link in the signature.

Just remember this useful point! Whether it would be for a white hat site or a black hat site.
