WebsiteBiz, a search engine and email marketing firm, has been selected by Microsoft to participate in a beta program for its new MSN adCenter program.

AdCenter is touted as the next generation online advertising platform and is designed to compete with other players such as Google and Yahoo.

“Being one of the first search engine marketing agencies in the country to have direct access to MSN adCenter allows our clients to be introduced to this emerging media opportunity sooner,” said Eric Dudley, president of WebsiteBiz. “We may also be able to offer better buys for cost per click advertising as a result of our participation in this beta group.”

WebsiteBiz said the adCenter may offer a “less expensive choice” for placing online ads.
