Ingenio brings pay-per-call ads to InfoSpace

The company is set to announce that ads from its network will appear on another search site.

Pay-per-call advertising pioneer Ingenio was set to announce Wednesday that ads from its network would appear on InfoSpace's search site.

Under the pay-per-call model, advertisers include their phone number next to links and pay only when a consumer calls them. Advertisers pay on average $9 to $10 per call, compared with 50 to 60 cents per click that advertisers pay on Google's AdWords network, said Marc Barach, Ingenio chief marketing officer.

Ingenio already offers pay-per-call ads on America Online and handles more than one billion searches per month, he said.
