Google on Thursday reported that its quarterly profit jumped on revenue that climbed 22 percent to $15.96 billion, but still cannot take full advantage of users' shift to mobile devices. The company said that its profit during the three months ending June 30 rose six percent from a year ago to $3.42 billion.

"Google had a great quarter with revenue up 22 percent year on year, at $16.0 billion," chief executive officer Patrick Pichette said in an earnings release.

"We are moving forward with great product momentum and are excited to continue providing amazing user experiences, with a view to the long term."

Google said a key factor in revenues was the jump in "paid clicks," for ads related to search on Google and its partner sites.

Total paid clicks were up 25 percent from a year ago and two percent from the past quarter, while the average cost per click -- the price that advertisers pay each time someone clicks on an ad -- was down six percent from a year earlier.

However, CPC in Google talk dropped 6 percent from the year ago quarter, largely because of the shift to increased mobile advertising.
