Free web hosting with advertisements splattered across the web pages may be fine for individuals who want to show their website to family and friends only. However, for businesses who want more professionalism and style, they must use more complex web hosting that removes much of the limitations of personal web hosting.
The reason that businesses need more complex web hosting is the fact that their website will often contain more pages and content than a personal web site. Business websites will often receive much more visitors, and it will therefore need much more attention and bandwidth from the web hosting service. More complex web hosting services will often provide enhanced database support which is important for businesses that have large databases of information about their products, services and clientele.
