Yesterday I wrote a very detailed write up on Google Local Business Center Adds Photos, Attributes, Maps Corrections & Stats. The features include (1) upload images to be displayed on the map, (2) add more attributes to your listing, (3) reset your Google Maps pin/marker and (4) see your stats for your business listings.
One of the cool interactive features I like is how you can easily set the marker location (i.e. the Google pin) to a new spot on the map. Here is a quick screen cast of it in action. Look at it bounce, how cute...
So make sure to read my Google Local Business Center Adds Photos, Attributes, Maps Corrections & Stats at Search Engine Land for all the new features.
