We have put on line a simple, searchable interface to the Google Local Business Center (LBC) categories and synonym lists. The idea is to to assist in early planning and judicious picking of the most appropriate categories for your LBC listing. At this point, the categories included are for the US LBC only.
Late last year I published the Google LBC Category list as an HTML page of all the categories but I wanted to make the list more manageable so I have placed it in a database with a simple search interface.
Your feedback and suggestions would be welcomed!
