Citation Data Aggregators: The Engine Behind Local SEO
Most local SEO guides tell you to build citations on Yelp, Yellow Pages, and a handful of industry directories. That advice isn't wrong, but it's incomplete. The real engine powering your citation ecosystem isn't those individual directories — it's the data aggregators operating behind the scenes. Understanding how aggregators work, and submitting directly to them, gives you leverage that directory-by-directory manual citation building simply can't match.
Key Points
- Four major data aggregators — Foursquare, Data Axle, Localeze, and Acxiom — supply business data to hundreds of directories, apps, and mapping platforms simultaneously.
- An inaccurate record at the aggregator level propagates errors to dozens of downstream sites automatically.
- Correcting your data at the aggregator level is more efficient than correcting each directory individually.
- Google uses aggregator data as a secondary signal to validate your business information.
- Aggregator submission is a one-time process (plus periodic updates) with compounding long-term benefits.
What Data Aggregators Are and Why They Matter
Think of data aggregators as wholesale suppliers in a business data marketplace. They collect business information from thousands of sources — public records, yellow pages, business registrations, utility companies — then package and sell that data to publishers: directories, voice assistants, navigation apps, and local search engines.
When Yelp, Apple Maps, TripAdvisor, or Waze needs to populate or verify a business listing, many of them turn to aggregator data rather than collecting it directly. A single inaccuracy in your aggregator record can propagate to 50–100 downstream destinations simultaneously.
This is also why you sometimes see old addresses or wrong phone numbers on obscure directories you've never heard of. You didn't submit to those directories — your aggregator data did it automatically, and the information it had was wrong.
The Four Major Aggregators
Foursquare (formerly including Factual)
After acquiring Factual in 2020, Foursquare became one of the dominant location data providers in the US. Foursquare data powers apps, navigation systems, and location-based advertising platforms. It's particularly strong for restaurant, retail, and hospitality businesses. Submit directly via Foursquare's Business Owner portal.
Data Axle (formerly Infogroup)
Data Axle is one of the oldest and largest business data providers in North America. Their database supplies data to YP.com, Superpages, CitySearch, and dozens of niche directories. They compile data from government records, postal services, and business surveys. Businesses can update their Data Axle record directly through their submission portal.
Localeze (now part of Neustar/TransUnion)
Localeze specializes in local business data and has historically been a major supplier to Bing, Yahoo, and hundreds of smaller directories. Updating your Localeze record is particularly important for businesses wanting accurate Bing Maps listings, since Microsoft relies heavily on Localeze for business data.
Acxiom
Acxiom operates at the intersection of business data and consumer data. While less directly visible in local SEO than the others, Acxiom's business data feeds into marketing databases and data providers that influence local visibility in indirect ways. They're worth including in your aggregator strategy even if the ROI is harder to measure directly.
How to Audit Your Aggregator Records
Before submitting corrections, understand the state of your existing records. Use these free tools:
Moz Local's Check Listing tool — Enter your business name and zip code to see your current presence and accuracy across aggregators and major directories.
BrightLocal's Citation Finder — Shows which directories have your business listed and flags NAP inconsistencies.
Yext's Scan — A quick scan that shows how your business appears across their network of publishers (which includes many aggregator-fed sites).
Look specifically for:
- Old addresses from previous locations
- Disconnected or changed phone numbers
- Incorrect business name variants (misspellings, abbreviations)
- Missing website URL
- Wrong business categories
Submitting to Each Aggregator
Foursquare: Visit foursquare.com/business and create a business owner account. Search for your existing listing, claim it, and verify via phone or postcard. Once verified, update all fields and submit.
Data Axle: Visit data-axle.com and look for their "update your listing" option, or use their partner submission portals. Some agencies submit to Data Axle via reseller partnerships. The key fields to complete are: business name, address, phone, website, categories, and business description.
Localeze/Neustar: Their direct submission process has evolved over the years. Currently, the most reliable path is through tools like Moz Local, Yext, or BrightLocal, which have direct relationships with Localeze for data submission.
Acxiom: Direct submission to Acxiom is available via their Consumer and Business Data Portal, though it's less straightforward than the others. Many businesses handle Acxiom through a citation management service.
Why NAP Consistency Matters at the Aggregator Level
NAP stands for Name, Address, Phone. Consistency in these three fields — exactly consistent, not just approximately — is the foundation of citation authority.
If your business name is "ABC Plumbing" on your GBP but "ABC Plumbing LLC" on Data Axle and "A.B.C. Plumbing" on Foursquare, search engines see three different signals and must decide which to trust. This ambiguity can suppress your rankings even if all three listings have your correct address and phone number.
Before submitting to aggregators, decide on your canonical business name (exactly as it appears on your signage and legal registration) and use it identically everywhere.
Aggregators and Voice Search
As voice search has grown through Siri, Alexa, Google Assistant, and Cortana, aggregator data has become even more important. Voice assistants often pull business information from the same aggregator-fed databases that power directory listings.
When someone asks Siri "find a dentist near me," Siri queries Apple Maps, which in turn validates business data against aggregator records. If your dental practice has a stale phone number in Foursquare's database, a voice search might give a prospective patient a dead number.
Submitting accurate data to aggregators is therefore also an investment in voice search visibility.
How Often to Resubmit
Aggregators periodically re-pull data from their source databases, which can overwrite manual updates with incorrect data from old sources. This "data refresh" problem means your aggregator records can drift back to inaccurate information even after you've corrected them.
The most reliable defense is using a citation management service (Moz Local, BrightLocal, Yext, or Whitespark) that maintains an active "lock" on your data by continuously feeding your correct information to aggregators. Without a managed service, plan to audit your aggregator records every 6 months and resubmit if you find drift.

Frequently Asked Questions
Q: How long does aggregator data take to reach downstream directories? A: Typically 4–12 weeks. Some directories update frequently; others update their business database only quarterly. Don't expect overnight results.
Q: If I use Yext, do I still need to submit to aggregators separately? A: Yext has direct relationships with many aggregators and will distribute your data on your behalf. However, Yext subscriptions are ongoing — if you cancel, your managed listings may revert. Manual aggregator submissions are permanent.
Q: My business moved two years ago. Is it too late to fix aggregator records? A: No. Update your aggregators now. It will take 2–4 months to propagate to all downstream sites, but correcting it is always worth doing.
