Internet Blog Marketing means using the internet to market products or services on your blog. That would be the simplest explanation to it.
Today, marketing in the internet is not as easy as before. There is a lot of competition and everyone wants to be a part of the pay per click programs. In order to become successful at this, you need to choose you own market. Be unique. Do not use a single blog to market a lot of things online unless they are relevant. Choosing your market is a little difficult. Some will tell you to follow your passion and chose something that you know and love.
