Kelkoo – which was sold by Yahoo to private equity firm Jamplant in 2008 for more than $350m less than it was bought for four years earlier – is expanding its global footprint, aiming to grab increased market share in a sector that has seen increased pressure from Google and Bing.

Kelkoo.com, currently in beta, has over 2m product offers from more than 1,500 retailers, including Sears and Walmart, with the figure expected to rise to 5m by the end of the year. It’s focusing on natural search, blogging outreach and word-of-mouth for marketing.

Stables told new media age, “We want to be the best shopping comparison site in the world. The US is the biggest single market: if you want to be a global brand then you have to be there.”

Stables, who joined Kelkoo last year, said the company had been biding its time since it left Yahoo, but he was confident it could be seen as a pioneer in the comparison sector once again.

“Things didn’t move forward with Yahoo as people would have liked. We’ve had a look at who we are and where we want to go, and that’s to be seen as the best,” he added.

The US becomes Kelkoo’s 11th market.
