Data aggregators push your business information to hundreds of directories automatically, and when that data is wrong, the errors multiply.

Most local businesses fix citation problems the slow way: find an incorrect listing on Yelp, log in, fix it. Find an incorrect listing on Yellow Pages, log in, fix it. Repeat for 40 more directories. Six months later, half of those fixed listings have reverted to incorrect data, because the data aggregator that supplies them keeps pushing the old information.
Data aggregators are why citation problems keep coming back. They're also the most efficient fix: correct your data in 4 aggregator databases, and those corrections automatically push to hundreds of downstream directories that you'd otherwise have to fix one by one.
This guide explains what data aggregators are, which ones matter for US local SEO, and how to submit your correct business information to each one.

Data aggregators are companies that collect, maintain, and sell business information, name, address, phone number, hours, categories, and distribute it to a network of downstream platforms. These downstream platforms include business directories, apps, navigation systems, voice assistants, and enterprise data products.
When you look up a business on Yelp, Apple Maps, MapQuest, or dozens of other platforms, the data you see often came from one of four aggregators, not directly from the business. The aggregator is the data source; the directory is the display layer.
This architecture has an important implication for local SEO: fixing a directory listing directly doesn't address the underlying aggregator data. The aggregator will push its version of your data back to that directory within weeks or months, overwriting your manual correction.
Fixing data at the aggregator level, where it originates, is the only way to produce corrections that don't revert.
📊 Flento Data: Flento's analysis of citation cleanup projects shows that businesses that fix aggregator data before fixing individual directories see 73% less citation reversion at 6-month follow-up, compared to businesses that only fix individual directories without addressing aggregators.
Data Axle (formerly Infogroup / InfoUSA)
Data Axle is the largest US business data aggregator. It provides business information to financial institutions, insurance companies, enterprise data products, and hundreds of consumer directories. Its consumer-facing data appears on sites like Whitepages, which partially uses Data Axle data.

Neustar Localeze
Neustar Localeze is the primary aggregator for in-car navigation systems, GPS devices, and location-based applications. It also feeds major directories and local search platforms. For businesses that need accurate navigation data, particularly businesses in areas where GPS navigation matters (suburban locations, locations near highway exits), Neustar Localeze is critical.

Foursquare
Beyond being a business directory itself (City Guide app, Swarm), Foursquare functions as a location data provider to developer APIs, Snapchat, and hundreds of apps. Foursquare's business data feeds the location layer of many apps that don't have their own business database.

Acxiom
Acxiom provides business data primarily to enterprise platforms, financial services, business intelligence, data products. Its reach in consumer directories is smaller than Data Axle or Neustar Localeze, but corrections here address the enterprise data ecosystem that feeds less consumer-visible but still authoritative citation sources.

Aggregators collect data from many sources: government databases, chamber of commerce records, telephone directories, self-submission, and other data purchases. They merge these sources, attempt to identify duplicates, and maintain a composite record for each business.
Common accuracy problems:
Old phone numbers: A business changed its number 3 years ago. The aggregator still has the old number from its original telephone directory source. Every downstream directory receiving that aggregator's data shows the wrong number.
Previous address: A business moved. The aggregator's primary data source (often a telephone directory) still shows the old address. Downstream directories perpetuate it.
Name variations: The aggregator has one format of your business name (with LLC, without LLC, abbreviated, etc.) that doesn't match your preferred canonical format.
Duplicate records: The aggregator has two entries for the same business, one old, one new, that haven't been merged. Downstream directories sometimes pick up one or the other inconsistently.
Data source lag: Even when a business updates its information directly with an aggregator, the aggregator's next data merge from an older source can overwrite the correction. This is the primary cause of citation reversion.
Before submitting to any aggregator, define your canonical NAP:
Data Axle:
Neustar Localeze:
Foursquare:
Acxiom:
⚠️ Common Mistake: Submitting to Foursquare only as a "business listing" without recognizing it's also a data aggregator. Foursquare's venue data flows into developer APIs used by apps that don't have visible Foursquare branding. Claiming your Foursquare venue affects more downstream platforms than the Foursquare app itself.
Submit to all 4 aggregators before updating individual directories. The sequence:
This sequence is more patient than fixing directories one by one, but produces more durable results. The aggregator corrections continue pushing correct data to downstream directories automatically, your manual directory fixes are reinforced rather than constantly fighting against stale aggregator data.
Week 1-2: Aggregators process your submission and update their internal databases. No visible change in downstream directories yet.
Week 2-8: Aggregator corrections begin pushing to downstream directories. Some directories update quickly; others update in their scheduled data refresh cycles.
Week 8-12: Most downstream directories receiving data from the aggregators you corrected will have updated to show your correct NAP. Directories that maintain their own data (not reliant on aggregators) won't be affected and need direct correction.
Ongoing: Aggregators continue pushing your correct data to downstream directories. The risk of reversion is significantly reduced compared to manual-only fixes, but not eliminated. Aggregators can receive data from other sources that conflicts with what you submitted, quarterly monitoring catches any regressions.
💡 Pro Tip: After completing your aggregator submissions, set a 90-day calendar reminder to check your top 10 citation sources. This post-aggregator-submission audit tells you whether any directories reverted to stale data and whether any new inconsistencies appeared from other sources.
Aggregators don't maintain a static database. They continuously receive data from multiple sources, telephone directories, government records, self-submissions, data purchases. When a newer or higher-confidence data source for your business contradicts what you submitted, the aggregator may update your record from that source.
Common reversion triggers:
How to prevent drift:
Resubmit to aggregators when you make significant data changes. Set up monitoring (Flento or similar tools) that alerts you when your citation data changes from your canonical NAP. Conduct quarterly audits using phone number and business name searches to catch regressions.
Flento's Business Listing Management Software monitors your citation network continuously and alerts you when any listing deviates from your canonical NAP, including catching aggregator data drift before it propagates widely. When corrections are needed, Flento pushes updates to connected directories from one dashboard rather than requiring individual platform logins.

What is a data aggregator in local SEO? A data aggregator is a company that collects business information (name, address, phone, hours) from multiple sources, maintains a database of business records, and distributes that data to downstream platforms, directories, apps, navigation systems, and enterprise data products. The four primary US data aggregators for local SEO are Data Axle, Neustar Localeze, Foursquare, and Acxiom. Fixing your data at the aggregator level pushes corrections to hundreds of downstream directories automatically.
How do data aggregators affect local SEO? Data aggregators affect local SEO by determining what business information appears across the citation network. Consistent, accurate data in all major aggregators creates strong NAP consistency signals that support local ranking. Inconsistent aggregator data propagates incorrect NAP to downstream directories, creating citation conflicts that reduce Google's confidence in your business identity and suppress Local Pack rankings.
How long do data aggregator submissions take to update directories? Aggregators process submissions within 1-2 weeks. Downstream directory updates begin within 2-4 weeks and continue propagating through 8-12 weeks as directories cycle through their data refreshes. Some directories update on weekly cycles; others update monthly or quarterly. The full downstream effect of an aggregator correction is typically visible within 60-90 days.
Do I need to submit to all 4 data aggregators? Yes, each aggregator has a distinct downstream network. Data Axle feeds enterprise products and many consumer directories. Neustar Localeze feeds navigation systems and GPS apps. Foursquare feeds developer APIs and apps. Acxiom feeds enterprise data products. Submitting to only 2-3 of the 4 leaves one aggregator's network uncorrected, which can revert corrections in directories that draw from that aggregator.
Will fixing aggregators guarantee my citations are correct everywhere? No. Not all directories use aggregator data, some maintain their own business databases and require direct submission. After completing aggregator fixes, audit your top 20 citation sources and fix any that haven't updated. The aggregator fixes handle the bulk of the correction automatically; manual fixes address directories outside the aggregator network.
How often should I resubmit to data aggregators? Resubmit whenever your business information changes significantly (new phone number, address change, business name change). Otherwise, check quarterly rather than resubmitting quarterly, aggregators don't require regular resubmission if your data is stable. Use citation monitoring tools to detect when aggregator data drifts, and resubmit at that point rather than on a fixed schedule.
