Yahoo has reported that revenue for the second quarter ended June 30, 2015 grew 15% year-over-year to $1.04 billion, attributed to the 60% growth in mobile, video, native, and social advertising.

MaVeNS -- revenue from mobile, video, native, and social advertising -- represented 25% of traffic-driven returns in the second quarter of 2014, and rose 35% in the second quarter of 2015.

"Our MaVeNS investment businesses across mobile, video, native and social grew to nearly $400 million in revenue this quarter, delivering 60% GAAP growth year-over-year," said Marissa Mayer, CEO of Yahoo, in a prepared statement.

While revenue from Yahoo's MaVeNS business in Q2 2014 was $249 million, non-MaVeNS revenue fell slightly to $725 million in Q2 2015, down from $742 million.

Mobile revenue represented 16% of traffic-driven revenue in the second quarter of 2014, rising to 22% in the second quarter of 2015. Gross mobile revenue for the second quarter of 2014 and 2015 was approximately $272 million and $415 million, respectively.

Revenue from display ads, excluding the traffic costs, rose 3.3% to nearly $407 million, up from $380 last quarter. eMarketer estimates Yahoo held 2.2% of the $74.82 billion market in 2014, but will drop to 1.9% this year.

Gross search revenue was $920 million for the second quarter of 2015, an increase of 15 percent compared to the second quarter of 2014. Search revenue rose 15% in the quarter compared with the year-ago quarter to $521 million on a GAAP basis.

Cost of revenue, TAC paid to search partners was $106 million, for the second quarter of 2015 compared to less than $1 million in the second quarter of 2014.

In search, Yahoo held 2.5% share of the $70.18 market worldwide in 2014, compared with 4.2% for Microsoft. Google led market share worldwide last year with 54.7% of worldwide search ad spend but eMarketer forecasts the Mountain View, Calif., company's share will fall to 54.5% this year. 

The number of paid clicks rose approximately 13% compared with the second quarter of 2014. The price-per-click rose approximately 4% compared with the second quarter of 2014.
