We don't have any way to handle multi-language listings at this point in time, and we strongly encourage businesses to only create one listing per physical address. However, it's a great suggestion to support these types of business listings - maybe we'll be able to support this in the future.
There are two issues here:
- Does the site allow the business listing itself (e.g. address and contact info, etc.) in multiple languages?
- Does a local search site allow the listing of multiple web sites, in different languages?
At Nelso, we've got (1) covered. Simply by adding a listing in his or her native language, a business owner automatically gets listings and business details in all the languages that Nelso supports (and a lot of links - every language on Nelso has its own domain, so adding an URL to a business listing results in links from seven Nelso sites). This by itself is very useful for a business owner, especially restaurants and bars that want to reach tourists.
As for (2): this is an interesting idea (allowing businesses to link directly to the parts of their sites that are in different languages), and we might add this. Most multi-language sites have a splash page that allows the user to choose a language, but in some cases it might be useful to let a business owner explicitly link to the different languages on his or her site.
