Google says it shook off the slowing economy to boost its third-quarter profit by 26 percent to $1.35 billion.

The strong showing might be enough to reassure jittery investors worried that the online advertisers fueling Google’s growth will curb their spending to save money in a drooping economy.

The earnings announced Thursday easily exceeded the average estimates among analysts polled by Thomson Reuters. Excluding costs for stock compensation, Google says it would have earned $4.92 per share _ 17 cents above analysts’ projections.

The company’s net revenue rose 34 percent to $4.04 billion _ about $20 million below the average analyst estimate.
