Many a company has emerged that designs professional, high quality websites for businesses and individuals. Some of these companies also offer site hosting free of charge for those who create their sites through their services. A feature that is essential to each and all websites is a site map.

A site map, which shows where certain areas of interest are located on the site and also links to them, includes information on web site standards and compliance with those standards, website design, website hosting, search engine positioning, and on viruses, trojans, and other computer problems. Site maps are also important for search engine optimization.
