A Metasearch engine is essentially a search tool that allows users to search for different search engine results or databases in a single list. The search results for requested keyword are displayed in a single list according to different sources. Reef FX is something more than a simple metasearch engine. Other than providing a broad search criterion like other search engines, the Reef FX also offers a number of free services to its visitors. These include free coupons, recipes, web directory, and wide range of information on dieting, pets, and more.
