Niche blogging is the act of creating a blog with the intent of using it to market to a particular niche market. While it could be argued that all blogs are, in some form, a niche blog, the term as it applies to marketing refers to a particular kind of blog.
Niche blogs are sometimes referred to as splogs, but this is a misnomer. Even though the desired end result for the niche blogger is to make money, the niche blog itself often contains valuable information. Most pay-per-click advertising is content-sensitive, so it is vital to the niche blogger to have useful content that is related to the chosen niche.
Neither blogging nor niche marketing is a new concept. However, only in recent years has the concept of a niche blog come into being.
Because people's interests often change over time, it is important for a successful marketer to stay up-to-date on current trends. By using free services, the niche blogger can quickly adapt to the changing market and create a new blog marketed to that niche.
In order for a website to be profitable, it must have visitors. Normal websites require search engine optimization or paid advertisement in order to gain visitors. Blog services like Blogger, on the other hand, incorporate Really Simple Syndication (RSS). Using this technology, the niche blogger can inform various online directories of the blog's existence. They, in turn, provide links to the blog. Visitors to these directories are then exposed to the blog's listing and may choose to visit the blog. Thus, the directories act as a marketing tool for the niche blogger.
