Shares of Google surged almost 12 percent to $592 per share in after hours trading yesterday after the company posted second-quarter earnings of $2.51 billion, or $7.68 a share, beating Wall Street expectations of $7.85 a share on revenue of $6.55 billion.

Total revenue topped out at $9.03 billion, an increase of 32 percent year-over-year. Excluding traffic acquisition costs of $2.11 billion, Google's second-quarter revenue was $6.92 billion.

Free cash flow rounded out at a healthy $3.6 billion for the second quarter.

Google's Android platform continues to evolve as the glue that binds all the company's many pieces together. CEO Larry Page said the company is now activating 550,000 Android devices a day. That's up from 500,000 activations a day as reported by Andy Rubin via Twitter on June 28 of this year. There are currently more than 400 different types of Android devices available globally.

The Android Market is also doing well. Google said the online app shop, which now features movie rentals and books, now has 250,000 apps, with more than 6 billion downloads to date.

The company said success with voice search traffic on mobile devices, which is up six times over the previous quarter, has prompted the company to develop the feature for desktops.

Page took yesterday's earnings call, which was broadcast live on YouTube, to voice his excitement about the company's new Google+ product released last week on a limited trial. 

Page said Google+, which is open right now by invite only, now has more than 10 million users, with over 1 billion items shared and received in a day. Page said emerging products like Google+ are about developing long-term business that can be monetized over time.

When thinking about Google and its many products, Page said he breaks the company down into three parts: search and ads; existing profitable consumer-facing products like YouTube, Android and Chrome; and new products like Google+, local and commerce.
