Google (NASDAQ:GOOGL) has reached across the Atlantic Ocean for its latest asset buy. The company announced it has acquired Spider.io, a privately held company based in London that specializes in combating fraud in online advertising. The terms of the deal were not made public.

In an entry posted today on the official blog of Google advertising subsidiary doubleclick, the company's Vice President of Display Advertising Neal Mohan wrote that "by including spider.io's fraud fighting expertise in our products, we can scale our efforts to weed out bad actors and improve the entire digital ecosystem." He added that Google will incorporate Spider.io's technology into its video and display ad offerings.

Spider.io's solutions assist by identifying networks of hijacked PCs and devices that are used as "bots" to inflate the number of ad views.
