Google Inc. has bought Measure Map, an online analytics tool for blogs.

The product was bought from San Francisco consulting firm Adaptive Path for an undisclosed sum. Jeff Veen, an Adaptive Path founder and product director for Measure Map, was hired by the Mountain View, Calif., search engine.

Measure Map is meant to help bloggers understand how their sites are used. The tool's capabilities include tracking visitors and their activities, as well as tracing the origin of links to blogs from other sites.

"Today, as the Measure Map team joins Google, our mission remains the same: to build the best possible user experience so people can understand and appreciate the effect their blogs -- their words and ideas -- can have," Veen said Tuesday in a posting on Google's company blog.

The technology is Adaptive Path's first product. It was highlighted by Macromedia, a unit of Adobe Systems Inc., at the Web 2.0 Conference in San Francisco in October.
