We know that local search is driven in large part by the databases of infoUSA, Acxiom, Switchboard, and DeepData. And that they in turn use Yellow Pages and White Pages as a major source.
But can we shed any light on exactly which directories they source, and which ones they keypunch (as opposed to getting a data tape)?

The real players are infoUSA, Acxiom, and Amacai

Where do infoUSA, Acxiom, and Amacai get the bulk of their business listings from?
Do they keypunch (type in) from the printed Yellow pages and White Pages?
Or do they get data tapes from the telco?
Or do they process directory assistance data tapes?
It matters because all three data sources are slightly different. And it matters because ILEC's (old bell system companies) are required to share Yellow Pages data with competitors -- but the listings so shared may not be complete.
|Where do infoUSA, Acxiom, and Amacai get the bulk of their business listings from? |
this is Amacai's words:
|We begin by capturing over 75 million business listings from multiple telco-verified data sources chosen to ensure maximum coverage and minimal overlap. The information in each listing is carefully analyzed, judged for relevance, and consolidated into a single "super record" that contains the most complete and significant information for each business location. |
ultimately, data is compiled from numerous sources. - bulk feeds, scanned directories, you name it... to have fresh and unique business data, you have to rely upon multiple sources.
amacai, for example, is known for their scanning of print yellow pages and other directory sources to obtain digital information that is cross referenced and enriched.
as one wise person put it to me, "they take our damn data, and sell it back to me."
infousa is known for its telemarketing team of business listing verification. They have well over a 1000 telemarketers calling businesses, and yes, updating records one by one.
as far as legislation concerning the telco's data, i don't know, but i can tell you this. the telco's use the above three to fuel their iyps.
note also that updating your info on these providers is as simple as going to their web site. businesses seem to be in the mood to contribute. that is how diverse their data collection strategies are.
Is there a way to supply bulk updates, as opposed to onesey updates, to these companies? Updating 150 branch locations at three providers gets a bit tedious.
Yes. Critical issue, brycen. And I am intimately familiar with the issues and business opportunity surrounding this pain. Companies should just be able to Register, dare we say once.
