Google mobile struggles continue

Even after cutting ties with Motorola, Google still hasn't solved all of its mobile problems.
Advertisers continued to pay less for advertisements on Google sites last quarter, as the company struggles to convince marketers to pay as much for mobile ads as desktop ads.

Those marketers paid 11% less per ad in the fourth quarter of 2013 than they did a year earlier. Google's overall sales and profit rose, however, because advertisers bought significantly more ads last quarter than they did during the same span in 2012 -- up 31% from a year ago.

In other words, even though advertisers are paying less for mobile ads, they're buying a lot of them.
Google (GOOG, Fortune 500) reported sales of $16.9 billion in the fourth quarter, up 17% from last year, just edging out forecasts of analysts surveyed by Thomson Reuters.

Profit grew too, rising 17% from a year ago to $3.9 billion. Excluding one-time charges, Google reported earnings of $12.01 per share -- well below Wall Street analysts' estimates of $12.20 per share.
Google shares fell slightly in after hours trading.

On Thursday Google said it was selling Motorola Mobility -- the money-losing mobile phone unit Google bought in 2012 for $12.5 billion. Though Google sold the venture for just $2.9 billion, the company retained most of Motorola's patents and pocketed $3 billion the division had in cash. Plus, it previously sold off the set-top part of the company for $2.3 billion.

Google CEO Larry Page said it didn't make sense for Google to continue making mobile phones itself.
In the fourth quarter, Motorola lost $384 million.
