Perception is so important in dealing with other people in any aspect of human experience. In the field of internet marketing this is especially true. Your website visitors, subscribers and customers should perceive you as someone they can believe in; someone they can trust. To this end it is so important to always ensure that the information you provide is accurate and honest. Even if you are not the greatest expert on a topic your customers should perceive you as a source of reliable and valuable information. Never claim to be something you are not but by offering quality your subscribers and customers will consider you to be someone they can comfortably deal with.
A good starting point is to establish yourself in a particular niche. At a later date you may well wish to expand your business into other fields, but I would recommend that you operate in just one subject area to start with. The more specialized your chosen niche is, the easier it will be to promote yourself as the 'go-to' person. If the niche you choose is one where you already have an in-depth knowledge then you are in a very strong position to market within that niche. You can genuinely portray yourself as an expert by way of autobiographical notes added to your website, articles or sales pages.
If you do not have that level of expertise, concentrate on learning as much as possible about your niche through research and study. Immerse yourself in all aspects of the niche so you do become, at least, something of an expert, able to answer queries and give a genuine aura of knowledge which will go down very well with your customers. It has been said that the definition of an expert in any field is someone who knows more than you do. Any newly qualified teacher will tell you how, from time-to-time, they manage to stay just one lesson ahead of their students.
There have been libraries full of advice about how to select an ideal niche so I am not going to cover that here. You will find that information very, very easily via your search engine, but one piece of general advice would be to find a topic which has a significant following but which has limited coverage on the internet. As always with internet marketing, research is the key. The marketplace is vast so there are seams of gold out there as yet un-mined if you can find them. Go prospecting!
Being seen as an expert by your website visitors will always have a significant positive impact on your business but you do need people to find your website and related copy to be 'suitably impressed'. Finding a profitable niche which is largely undeveloped will make it easier to bring in the traffic as the competition will be much less fierce. Once you have people on your site then, and only then, can you impress them with your expertise, your available information and your products. You might say that these two things go hand-in-hand – traffic and expertise.
