A niche is an area of interest or product group. An example of an exciting niche would be dog training, a product group niche could, for example, be electric lighting. Both niches are things that people search for on the Internet, and both of these niches are searched for because people have problems that they want to solve. They are either looking for information on the subject to help them solve their problem themselves, or they are looking for physical products that will help them solve their problems.

A niche market is a way to solve problems in exchange for a financial reward. People who are searching online for dog training might be willing to pay money for the answers to their problems with their dog’s behaviors. People who are searching for electric lighting may also be looking for information, but it is far more likely they are looking to buy lighting products. A micro-niche is far more useful for an online business than a general niche. An example of a micro-niche would be Husky dog training or solar garden lighting. In these cases, people are searching for specific things, so if you are building a micro-niche site, you can target these potential customers more accurately. By displaying products on your website that are carefully matched to what your visitors are looking for you are more likely to make a sale. Another advantage of choosing a micro-niche is that there are millions of them.

Even today, it is still possible to find profitable micro-niches which have very little competition. This will enable you to enter a market that has a problem and provide that market with a solution that they can’t get from anywhere else. The secret is being able to find these niches. Niche markets and especially micro-niche markets provide online business owners with the opportunity to find business opportunities that have little competition. The trick is to find micro-niches that have low competition, but that also have a lot of people searching for them. It isn't easy to find them, but when you do, then these micro-niches can be extremely lucrative.

If you are unable to monetize these sites using informational products or physical products, then you can always use pay-per-click advertising on them.
