Now listed elsewhere

Marketers that buy pay-per-click and pay-per-call ads on Superpages.com can also opt for inclusion into Marchex's network of local online directories.

This is part of a new relationship between the companies. According to ClickZ, placements will occur via Enhance Interactive, Marchex's ad network.

Marchex publishes 150,000 local sites featuring business listings and customer reviews. The company says its network is used by 25 million users each month.

Superpages has actively boosted its ad own options of late. It now offers video ads to local advertisers through partner TurnHere. TurnHere closed a similar deal with YellowPages last week.

Local online advertising is expected to jump from $3 billion in 2007 to $8 billion by 2011, according to an eMarketer study published last year.
