Data aggregator
Also called: data amplifier, data provider, local data aggregator, primary data aggregator
A data aggregator is a company that compiles core business information (name, address, phone, hours) and syndicates it at scale to directories, maps, apps, GPS systems, and voice assistants. Search engines license this data, so aggregator accuracy shapes how you appear across local search.
In the United States, three companies handle most of this distribution: Data Axle (formerly Infogroup), Foursquare (which absorbed Factual in 2020), and TransUnion Digital Business Profile (formerly Neustar Localeze). Acxiom, long counted as a fourth, retired its directory services at the end of 2019. Foursquare alone maintains 100M+ points of interest across 200+ countries and territories and feeds location data to platforms like Yahoo, Redfin, and Nextdoor.
Why accuracy at the source matters
Google, Bing, and Apple license aggregator data to fill and cross-check their listings. That cuts both ways. A correct NAP record propagates outward and reinforces your presence, but a stale phone number or old address can repopulate directories you already cleaned, and it can override what you entered directly on a platform.
Aggregators run on batch cycles, not real-time syncs, so a change can take weeks to ripple across the ecosystem. Treat them as a foundation layer, not a quick fix. A typical cleanup runs:
1. Correct NAP at Data Axle, Foursquare, TransUnion
2. Claim and fix the primary platforms (Google, Bing, Apple)
3. Sweep secondary directories for old records
4. Re-check in 4-8 weeks for propagationConsistent name, address, and phone across these sources remains a core local ranking signal.
How it affects your traffic
For a local business, inconsistent listings across aggregators quietly drag down map pack visibility. Conflicting or duplicate NAP records make the engines unsure which data to trust, so you rank below competitors with clean citations. Correcting this at the source is slow and easy to botch, which is where our Local SEO work fits in: we audit your presence across Data Axle, Foursquare, and TransUnion, fix the source records, and clean the downstream directories so your name, address, and phone read the same everywhere customers and AI assistants look.
