Yahoo has taken some beatings on Wall-Street this year, but that could change, with the company announcing across-the-board increases in ad sales.

"In every single category, we are still growing and growing significantly," Wenda Harris Millard, Yahoo's chief sales officer, said at a UBS AG conference in New York on Tuesday, Bloomberg News reports. Yahoo's shares, which have fallen some 30 percent this year, were up almost 2 percent in response to the comments.

Millard added that Yahoo will benefit from targeting ads more precisely at users and selling spots on its less popular pages. Yahoo took a 20 percent stake in Right Media, which runs online auctions to sell non-premium ad space. "One of the things we need to do a better job of is monetizing non-premium" inventory, Millard said. "I'm paying a lot of attention to that now."
