Even with heated competition from Facebook, it doesn’t look like YouTube is about to slow down its momentum anytime soon. If at all.

Adweek has reported that Google has just revealed its second quarter earnings report, and, from the information provided, viewership has never been greater…and, for that matter, the same goes for advertiser money.

Mobile users on the site have averaged around 40 minutes per viewing session for the second quarter of this year, a 50 percent increase from the previous year. In addition, the number of advertisers for the site have risen 40 percent from last year as well, and the average spend across YouTube’s top 100 advertisers managed to rise 60 percent overall.

As a result, the site has generated $17.3 billion for the quarter, with a $3.9 billion profit. That resulted in a $60+ leap in the company’s stock price at the time of the report.

“Our strong Q2 results reflect continued growth across the breadth of our products, most notably core search, where mobile stood out, as well as YouTube and programmatic advertising,” said the company’s CFO, Ruth Porat, in the earnings release. “We are focused every day on developing big, new opportunities across a wide range of businesses. We will do so with great care regarding resource allocation.”

Between its variety of advertising – programmatic, video, display and search – the company’s revenue has increased by 13 percent to $12.4 billion across all Google-owned sites. In addition, paid clicks on these sites increased by 30 percent, and cost per clicks dropped 16 percent.

Who’s the core audience for these numbers It looks like 18 to 49 year olds. Said Porat, “Advertisers want to reach these audiences, and our focus is on the opportunity to get larger budgets moved to YouTube.”

Other numbers released in the report include:

  • YouTube has more than one billion users.
  • The number of users who visited the site directly via its homepage tripled compared to last year.
  • The number of YouTube stars – including Michelle Phan and Grace Helbig – earning six figures or more has risen 50 percent.
