Having multiple Local Business Listings (LBLs) with the same address has the negative impact of splitting the strength of your listings. We recommend you to delete the other LBLs with the same address. If they’re franchises, like “Subway”, they would be OK.
For other local search, visit our Google Maps Algorithm page, Google Maps Optimization (Google Maps SEO) page, Live Search Map and Yahoo Local page.
