This is some great information! I'm hoping that someone might be able to help me understand a few things ...
It's my understanding that out of UBL, Localeze, Infogroup, and Axciom, only UBL claims the listings for you and provides you with login credentials. And ... Localeze, Infogroup, and Axciom only take the listing information you provide and send it to different channels, however, you would still need to manually claim the listing on each site (Yelp, YP.com, Local.com, etc.). From what I've read, it seems like the benefit of submitting to Localeze, Infogroup, and Axciom is a "trust factor" that these sites have with these three data providers, which could in turn give you a little boost in local serps.
Is the above accurate?
Also, I've read that these data providers send out listing information to miscellaneous channels such as mobile apps and in-car navigation systems. If someone was to only manually claim listings and by-pass Localeze, Infogroup, and Axciom, how likely is it for that business to still be found in these miscellaneous channels?
I've read a ton of material and even spoken to many of these companies, however, I'm still having a hard time understanding any additional value of these data providers (outside of the ability to update multiple listings from a control panel and/or having enhanced listings). Has anyone found it more beneficial to just claim and maintain their listings manually without the help of these tools? And ... When looking to build a solid foundation for local seo, how crucial is it to use Localeze, Infogroup, and Axciom?
I would really love to hear what you've discovered in your travels and thank you for your responses.
