He joins Marchex from R.H. Donnelley where he was Director of Product Management and Innovation leading the organization's search engine marketing and search engine optimization solutions for R.H. Donnelley's national brands including DEX and Embarq.

"Marchex is in a great position to be a clear leader in call-based advertising," said O'Keefe.
