You have probably seen a few web companies that claim to offer a free website builder. When selecting a company that offers a free site builder you should proceed with caution. There can be a huge difference between those companies.
Many of those providers are offering website builders that are very short on features and extremely limited in design options. In addition, many are difficult to use and come with very limited support. They may be free but they will not provide what you really need----a site builder that enables you to develop an amazing website.
