The Multiple Listings Problem in Manhattan Local Search
Wednesday, August 13th, 2008by Jim Moran
In an effort to curtail manipulation of local search results, Google has recently articulated to local businesses that listing multiple business names at a single address is no longer acceptable. While this is a positive overall step for local search, the Manhattan local market presents too many obstacles to this approach for addressing mapspam.
In a city of skyscrapers, single addresses often host hundreds of businesses. Making matters worse is a predominance of mail forwarding centers that provide an authentic-looking mailing addresses for only a few bucks a month. In New York City, address redundancies are not the exception, they are the rule.
There are several scenarios for why businesses might share an address, including:
1. Legitimate businesses sharing a single office building.
2. Legitimate service providers (e.g., contractors, transportation, etc.) who obtain a Manhattan forwarding address to improve their local SEO. For examples, look up Yipit’s address on Google Maps and see our thousands of “neighbors.”
3. Businesses with an actual local retail presence that use multiple names and web presences. See #1 and #3 in a search for modern furniture.
4. Businesses with no local retail presence appearing local by using a forwarding or otherwise fabricated address.
But shouldn’t checking for multiple businesses solve all of these scenarios, and weed out the good from the bad? Not in Manhattan, where the vast majority of businesses share a building. But shouldn’t suite, floor or office numbers correct for this? Perhaps, but they’re rarely available. Analyzing a sample of Manhattan yellow page data reveals the following:
- % of businesses located at an address occupied by at least one other business: 83.2%
- % of those businesses whose address includes a suite, floor or office number: 31.7%
- n = 7,425
In less dense areas, automatically eliminating address redundancies can go a long way. In Manhattan, multiple businesses that share the same address cannot be eliminated prima facie, so you need a local authority to determine the correct answer.
