Posting on forums is one of the cheapest and fastest ways in which you can advertise your affiliate products on the Internet. However, in order to do this successfully, you must do a number of things with care. You cannot simply start a thread which contains your affiliate link straight away. You will almost definitely get banned from that forum board and you certainly won't get any sales from it. The general procedure involves making multiple posts on a forum board before you even setup a signature file, which includes a link to your site. Even if the particular forum you are using does not specifically mandate this, you will want to do this, anyway, as it will increase your credibility - which is your real goal. Finding a forum related to your niche is relatively easy to do. Simply type the name of your interest followed by the word 'forum' into your favorite search engine i.e. if your niche is golf, type in 'golf forum' into your browser and you will likely get a list of active forums on the return page. Alternatively there are a couple of URLs that you can use to obtain the same information. They are "big-boards.com" which is currently the largest forum directory on the Internet or you can use "board123.com/forum_directory.php" which has some lesser directories but does contain some forums that the first doesn't list. Once you have chosen a few forums that you are interested in, you will need to find out what their rules are when it comes to signature files. Some don't allow links and others do but may not accept these links to be of a commercial nature. It's vitally important to stick to the rules of these forums or you will find yourself banned pretty quickly. Once you have your list of forums that allow commercial links, it's time to start posting! Right from the beginning, make sure that you post messages that are meaningful and relevant. Set yourself up as an expert in your niche and try to give value to the group by posting useful articles and lists that others will appreciate. Only once you have developed a good reputation on these forums which will take approximately one to two weeks of regular posting, you can begin advertising through your forum signature. If it is allowed, make your signature eye-catching by using an assortment of colors, words and symbols. Link your signature to an affiliate product or an auto-responder course purposefully designed to capture email addresses. Repeat this process throughout all the relevant forums that you discovered earlier but ensure you pick forums that have high traffic, are used regularly and are audience specific to your niche. Not all forums are created equal and you do not want to waste time on those that are just too quiet to drum up any attention. Remember to add a memorable signature file so that you draw people to click on your link and you will find that this method will pay off considerably and much faster than other methods.
