It's almost impossible to find a niche that doesn't have some relevant forum dedicated to it. Then, if they have good traffic and allow it, you can implement a universal forum marketing strategy that can transform your business within a year. The entire plan doesn't have to take nearly as long as you might imagine. But if you want to get maximum value from your efforts, it will require some time and patience on your part. But that's your mindset and you have to decide what's best for you.
Most forum members act according to their personality. Others will be more extrovert or even introvert. So just be yourself and let people see your real personality unless it's highly offensive. If you're more reserved and unsure, then just observe the forum until you become comfortable enough to contribute. This is what is known as lurking and many people do it until they feel comfortable enough to contribute to the forum. You might be too afraid to make a first post. Begin by talking in other threads and providing useful information. Any time you enter a forum for the first time, there are some important things to look for. Looking around is essential for deciding on whether or not this forum is for you. You have to consider some things since you will be using the forums for your online marketing. For instance, some forum owners and members despise online marketers. This is something that will probably not occur if the owner is not very fond of IMers like yourself. You can sometimes find that out by reading the forum rules. The absence of links, and signatures, at the bottoms of posts is a clear sign online marketing is not allowed. The vast majority of forums, even if index they allow signatures, don't allow you to directly market to the community anyway. If they did, then the entire place would be one giant billboard and people would not like it.
When you sign up for a new forum, you will have the freedom to tweak your online presence. You can create the type of personality that you choose for others to experience. But,you never know what is going to happen, so do not get too wild with this. If you tend to be loud, you can stop this and do not do it any longer. There may not be a lot of people who are strong like yourself. But everything hinges on how well others see you. Depending on your niche, you may not want people to know how you really are. So, remember what you want to accomplish when dealing with all of this.
You can work a lot of forums and still only devote about five hours a week to the effort and, bring in a ton of profit from forum marketing. It doesn't get much higher in value than that when it comes to marketing. Diversity is the key to maintaining success over the long-haul when marketing online.
