Yahoo Search has been making headlines lately thanks to a five-year partnership with Mozilla, which sees the search engine become the default in the Firefox browser. The version that implements this just came out this week.

When Yahoo released its latest earnings report, it revealed that its search business is actually doing better than its display ad business. It would seem that things have been looking up lately for Yahoo Search, which in the time before Google, was the dominant means of searching the Internet.

While we’ve heard that Yahoo CEO Marissa Mayer isn’t a huge fan of the search and advertising deal Yahoo has with Microsoft, which was made before her time in the driver’s seat, we really haven’t heard a whole lot about the “Search Alliance” lately.

On Tuesday, Microsoft posted an update about its performance on its advertising blog. It says that the Yahoo Bing Network’s search and click volumes from smartphone users have more than doubled year-over-year, and that click volumes have outpaced growth in search volume. This, the company says, demonstrates “the high degree of consumer engagement and relevance of mobile ads on the Yahoo Bing Network.”

The technology and telecommunications verticals saw 300% year-over-year growth, while Retail, Autos, and Financial Services each at least doubled in click volume.

Microsoft tells advertisers they can expect more targeting improvements, app extensions, mobile product ads, and universal event tracking.
