You can find as many forums as you want that are relevant to your niche. The trick is in finding the right forum with the right amount of traffic to suit your Internet marketing needs. That may sound like a very long time, and if so then maybe you believe all the sales letters. With all good things, however, time and care are required in order to get a maximum ROI. But that's your mindset and you have to decide what's best for you.
It's always important to know why you're pursuing a particular marketing method. The same is true about forum marketing because you won't fully understand it unless you know the benefits. Essentially, forum marketing is networking with individuals and businesses that are similar to your own. Not simply about networking - it's about building relationships, and marketing from that standpoint. As you'll see when you start posting on the forums, the latter (relationship building) is to key component of it all. Building your brand is so important, and with forum marketing, you can be quite successful with it. The way you do that is by gaining exposure and offering value. When you are synonymous with value, then your forum reputation will grow. Forum marketing has many rules, but one of the most important is to provide value to the community. But consider that when you provide value, you'll be helping someone or more than one person. There could be many good reasons why people do not warm up to you. One might be because you think that you know everything. Basically it depends on how you talk about your topic. Sure, you might know what you are talking about, but you have to be cautious about your reputation. If other members do not feel warm and fuzzy when it comes to you then it will be hard in the long run. It will not matter how good you are if people do not like you.
Don't even think about networking on a forum until you know who the 'top dog' on the forum is, so to speak. You'll typically find there's really a handful of people who have this potential. There is some influence to this based on the sheer number of forum members too. Forums with long histories and large memberships will have more influence bringers than smaller forums. The influencing figures are different on different forums. With senior members and moderators you'll often be able to recognize others attempting to garner favor. Once you know who these people are, then you can work to build a rapport with them. Although forum marketing will work eventually, do not expect it to happen overnight. But it might be possible to see fast sales, depending on the forum and services that you are promoting. Some forums allow you to advertise your products or this contact form services, and when done right that can bring a fast cash windfall.
