Yahoo CEO Mayer: Microsoft partnership not performing

Yahoo CEO Marissa Mayer believes her company’s search partnership with software giant Microsoft should be reaping more rewards for both parties.

The two companies signed a 10-year agreement in 2010 to share their search technologies and strategies in order to make inroads on the market-dominating Google.

But speaking at the Goldman Sachs Technology and Internet Conference in San Francisco on Tuesday, ex-Googler Mayer indicated that the dynamics of the partnership had not the brought the companies forward in the search sector.

"One of the points of the alliance is that we collectively want to grow share rather than just trading share with each other," said Mayer, according to Reuters.

Analytics firm Comscore charts Google’s share of the US search market at 66.7 per cent – virtually unchanged from its 66.6 per cent share when Yahoo and Microsoft joined forces over two years ago. Comscore figures have the chasing companies currently holding 12.2 per cent and 16.3 per cent of the search market respectively.

"We need to see monetization working better because we know that it can and we've seen other competitors in the space illustrate how well it can work," Mayer added.

Mayer has made a significant impact since taking the reins at Yahoo back in July 2012, with the firm’s stock rising 30 per cent from the time of her arrival to reach Yahoo’s highest levels since 2008. But Mayer reiterated the importance of growing the company’s advertising platform to sustain a long-term recovery.

"I'm not confused. Our biggest business problem right now is impressions. Basically can we grow impressions, can we get growth happening here," Mayer said.
