Data aggregators are like the puppet masters of online business information. Giants such as Foursquare (yes, it’s still around in some capacity), Data Axle (formerly Infogroup), and Neustar Localeze compile and distribute your business details to dozens—even hundreds—of smaller directories. Think of them as a multiplier for your citation efforts. When you update your info with data aggregators, you’re not just fixing it in one place; you’re correcting it across the web. But these aggregators can also spread outdated or incorrect data if you’re not on top of it. One slip-up, and your old phone number can creep back into listings like a zombie from the grave. So yes, data aggregators are powerful—use them wisely. Keep your data fresh, accurate, and consistent, or risk a negative chain reaction. Done right, they’re your secret weapon for maximum exposure with minimal extra work.
