hey jake, good to see you here. maybe your new natural home.
>>Data from information providers is often incomplete.
>> businesses that are closed
yep. terrible problem.
>>the number one issue affecting local search at the moment is data quality issues, IMHO.
i agree that it is a critical shortfall. that is why it is critical for businesses to pay attention to the integrity of their business data.
and it is worth noting that there is a new breed of local search engines picking up on this shortcoming.
>>the engines you've listed Chicago use multiple data sources.
well, all of them have advertiser data that sit on top of this backfill data. most all of them all share advertisers. working together as distribution partners helps to further monetize the results pages above the free backfill. many of these distribution deals aren't even made explicit to the advertiser or the public.
<added> there are also some organizations that buy, clean, augment (with things like URLs), and resell this data to distribution partners including even some majors.<added>
regardless the axciom and infoUSA databases are the most often used and referenced local data providers on the internet. the list above is even much deeper than provided. and when one wonders why they can't find themselves in the backfill results or the new local search providers, one needs to start there.
consider this: when you submit your business to google local this is what comes back:
"... If you'd like to add, change, or remove a business listing in Google Local, please reply with: 1. The business' complete name. 2. The business' complete address. 3. The business' complete telephone number. ***We'll forward the information to the directory sources we use. They will work to authenticate the data and make the appropriate updates***
hmmm. we'll forward the info to authenticate? who might they be sending it to?
