Post relevant information to forums and genuinely contribute to discussions. And have your signature along so that your link will be there. When you visit sites with guestbook, forums, or blogs make posting leaving your link behind. And people will click it and find your site and shop.
Go to https://techyahoo.com/community for a list of forums.
But all the forums are yelling, “Don’t abuse forum rules!” What are forum rules? They don’t want you to post a link, even if it offers help. If you do, the moderator will delete your entry immediately and have you banned. If your signature is even allowed, nobody reads signatures. Ask this: when is the last time you personally read a signature?
It is only when your comments and discussion is so powerful that people will trace you. Like most traffic techniques, fun comes in first.
You should just try to help other and have fun while posting in forums and leave your signature so that anyone interested in you can find you.
