Internet Brands has reached an agreement to acquire Avvo Inc., an online directory of law firms and legal services, for an undisclosed amount, according to a press release.

Internet Brands will add the Seattle-based brand to several legal services search websites it already owns including Lawyers.com and AllLaw.com. The deal is expected to close soon.

Avvo attracts more than 100 million annual visits to its namesake website and mobile apps through an offering of legal services, attorney profiles, forums, and educational content for consumers and attorneys, according to the release.

The company was founded in 2006 and will continue to operate from its headquarters in Seattle under the direction of its existing leadership team. The Avvo brand will be retained following completion of the acquisition.
