  Mobclix has thrown down the gauntlet. The mobile ad exchange has launched a promotion challenging iPhone application developers to compare it side-by-side with rival network AdMob.

The effort invites developers to split ad impressions on their apps evenly between the Mobclix and AdMob for two weeks starting Nov. 16. (A minimum of 100,000 impressions of 300 x 50 ads per day is required.) If participants don't derive more revenue through Mobclix, then the company will award them $10,000 of free advertising on its exchange.

So why is Mobclix so confident that it can best AdMob head-to-head? "With the Mobclix ad exchange system, we're able to secure developers the greatest revenues via our partnerships with 20-plus leading ad networks and our yield optimization technology that ensures 100% fill rates and the highest eCPMs," boasted company co-founder Krishna Subramanian.

AdMob did not respond to a request for comment Friday.

The mobile ad smackdown highlights the intensifying competition in the space as companies jostle for market share in the emerging mobile advertising arena. And if Mobclix should emerge victorious from its competition, who's next up -- Google?
