Michael Bonfils is the Founder and Managing Director of SEM International (SEMI), a global search engine marketing network. Since 1996, Michael was one of the early pioneers in search engine optimization and created Century 21's first SEO program, from '98 to '99 he co-founded a real estate vertical search engine and was formerly in charge of Search Engine Strategy at Business.com in 2000-01.

By late 2001, he started an online advertising agency which eventually was sold to his partners in early 2004. Part of the settlement allowed him to retain the Hong Kong based Search Engine Marketing office which was held under SEMI's parent company, Hyper Interactive Corp.

Recognizing the need for US based agencies to properly provide SEM services for their clients in mainland China, Michael moved the office to Shanghai and tripled the revenue and client base of his Fortune 500 clientele. This event sparked a global need for his services in localized search marketing.

Today, SEMI is one of the leading global search engine marketing networks, covering Asia, Europe and the Middle East and Latin America.
