If you want to use forums for marketing or promotion of your blog or website then you have to follow instruction which are described below.

Always post you link on relevant forums which has discussions about the topics which you have discussed on your blog or website. Do not post your link at start. First answer some questions on forums, so that you would get popularity then afterward put your link in answer tagged as for more information: Link. The reader would surely visit your link to get more information. Some forums impose that before posting a link you must have ten threads on that forums. Such forums are popular one and to avoid unnecessary information they impose such policy. Be calm and patience and start working with your threads on forum with suitable content. Always take part on discussions on forums. Do not answer about those questions about which you do not know well because it would decrease your popularity. Do not try to mold discussion, just be the part and after some discussion put your link so that people consider it a genuine link and visit to get information and your blog or website must have such information for which a user visit it.  Before working on a forum you must have to read the policy so that you would not get banned in future. There are so many popular forums which could derive huge traffic to your website but in my experience the most effective one is “Yahoo Answers”. On this you just browse to suitable category and then answer the questions. At each answer you would get some points which are displayed on your profile. These points show your knowledge level and popularity. If you have more points then users would considered your answer authentic. After 200 points your link becomes enabled so that a user can click on it to browse your pages. But do not put link of your blog or website in each link because it is illegal to market a single website or blog on Yahoo Answers. The second one is facebook. Just find the relevant groups or pages and post your comments with your link there. Always try to facilitate people from your answers. If others are satisfied from information provided by you then they surely visit your link for more detailed information.
