ClickZ has details of a new experiment Google is conducting with ads on Google Maps.
A search on “hotels” in New York City returns an organic list of local hotels, plotted on the map with red markers and bracketed by sponsored hotel listings, plotted on the map with blue markers. The same search in other locations, such as San Francisco, doesn’t yet return the paid listings.
This is probably one of Google’s most relevant use of advertising in recent months. Very cool.
