Cumberland, Maine--A new business search engine called B2B Explorer and located at www.b2bexplorer.com launched Monday. The site aims to displace Yahoo! and other Internet search engines for Web users looking to locate businesses. The site is a free service, both for companies to submit information and for access to the directory. On the site, users can find detailed company descriptions, a listing of executives and a secure means to send e-mail to a listed contact. The site will also include a B2B Marketplace for electronic commerce and lead generation.
