New York-based Clickable has raised $14.5m in funding to help push its search-ad applications, while Marchex has retooled its local-search advertising platform

Ad-technology hopefuls are angling for ways to take a cut for themselves of Google's estimated $10.4bn annual search-advertising market.

One such start-up, New York-based Clickable, is trying to build a lucrative business by selling advertisers a simple software tool to manage and improve their search-marketing campaigns with Google, Yahoo and Microsoft. Because it can be tricky and time-consuming for advertisers to keep track of multiple search campaigns, Clickable lures them with a self-described iTunes-like application that shows which ads are working and which aren't.

Since the company's limited launch in February 2006 and bigger push this spring, it has attracted about 400 customers, which spend an average of $10,000 (£5,000) to $50,000 a month on search-ad campaigns. (On the high end, Clickable makes a five percent cut of that spending and three percent with ad agencies.)

Clickable plans to step up growth this autumn, thanks to a new round of financing. On Wednesday, Clickable will announce that it has raised $14.5m in a Series B round of financing from the Founder's Fund, as well as its previous investors Union Square Ventures and FirstMark Capital.

With this financing, the company has raised a total of $22.5m in the past year, including money from private investors former AOL chief executive Jonathan Miller and Peter Thiel, co-founder of PayPal and managing partner of the Founders Fund.

Clickable chief executive David S Kidder said that part of the growth plan in the next year will be to create a single 'Clickable' interface for other types of web advertising, including social media and display ads. Because the Founder's Fund is an investor, Kidder said Clickable will be looking to create tools for many of the venture firm's other portfolio companies, such as Facebook or Twitter.

Advertisers on social networks, he said, could eventually benefit from a single tool that could trace how ads are performing with other types of media. "Once social media can get connected to search, even to Google, advertisers can create a display ad campaign in Facebook and MySpace and connect that to a search campaign that converts [into a sale or action]," Kidder said.

Meanwhile, publicly traded internet advertising company Marchex will announce on Wednesday that it has launched a new platform called Marchex Connect 2.0. The technology, which updates its previous ad platform, lets local advertisers buy online search ads, 1-800 voice call search ads, and a business profile web page from one place. The company hopes it will help the estimated remaining 14 million small to medium-sized businesses in the US establish a presence on the internet.

Maybe that will be key to capturing some of the expected $16bn in search ad revenues by 2011.
