Google Inc. has acquired Measure Map -- a blog traffic analysis provider -- for an undisclosed amount.

Through Measure Map, publishers can track visits to their blogs and watch user activity. Measure Map is free, but by invitation only.

"Our goal has been to use the power of web analytics to help bloggers feel that same sense of connection with their audience. 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," posted Jeffrey Veen from the Google Measure Map Team on the Google Insider blog.
