Mamma.com® is a "smart" metasearch engine - every time you type in a query Mamma simultaneously searches a variety of engines, directories, and deep content sites, properly formats the words and syntax for each, compiles their results in a virtual database, eliminates duplicates, and displays them in a uniform manner according to relevance. It's like using multiple search engines, all at the same time.

Created in 1996 as a master's thesis, Mamma.com helped introduce metasearch to the Internet as one of the first of its kind. Due to its quality results, and the benefits of metasearch, Mamma grew rapidly through word of mouth, and quickly became an established search engine on the Internet. Mamma's ability to gather the best search results available from top search sources and to provide useful tools to its users has resulted in its receiving multiple Honourable Mentions in the Best Metasearch category in the annual SearchEngineWatch Awards.
