I ran across this the other day, and thought others might be interested: [localsearchguide.org...] . This is a Who's Who of data providers, search engines and vertical directories put together by the Yellow Pages Assocation and the Search Engine Marketing Professional Organization.
I found it while trying to figure out how to get my business into Acxiom, DeepData and infoUSA databases. Sadly, it did not answer my question (e.g. where do I advertise if I want to end up in all three databases? Must I go Yellow, or will White do? Can I go with a 'B' directory, or must I pay full fare at the ILEC?). But it has a lot of good background.
Until there is a product that brings this all together, you must go to these providers individually and submit, update, or enhance your business data. InfoUSA and Axciom have forms on their sites. It is free. Repeat process.
Your thinking about this in the right way. Consistant and accurate distribution of core business data is of much benefit to a business with respect to local search.
I've looked at getting listed directly with InfoUSA, DeepData, and Axciom but not figured out how to apply them to my situation.
The business I'm working with has a main office, but customers are not served at the office. The actual business is conducted at 45 separate brick & mortar pickup kiosks, none of which have telephones.
The main office shows up two or three times in most IYP's (the current address, and an old satellite office that had a phone). But the kiosk locations are unknown. SBC quotes $12/month for a single line YP listing. But that's more money than I can spend on an experiment that won't yeild results for at least a year (if ever).
