Another cute trick is to put places on google maps at 0,0 or another strategic location, so that anyone looking at a place with that location will find it. Last I looked Ace Advertising Signs had put a place at 0,0, it's been removed now I think but you can still see the icon at certain zoom levels on classic maps as the tiles are cached:
