What is Data Aggregators?

The big four: Data Axle (formerly InfoUSA), Localeze (owned by Neustar), Foursquare (merged with Factual), and Infogroup. These feed data to hundreds of directories, apps, and GPS systems. Submitting to all four covers the widest distribution of your business information.

Weeks to months. Aggregators update on their own schedules, and the downstream sites they feed may update even less frequently. Don't expect instant results, it's a slow process. If you change your business info, plan for a lengthy propagation period.

Yes. Aggregators are efficient but don't reach everything. Manually claim and optimize your most important directories, Google, Yelp, Bing, Apple Maps, Facebook, industry-specific sites. Use aggregators for the long tail, but don't rely on them exclusively.
