The part that compounds. Aggregators are wholesalers of business data: you submit once, and they feed hundreds of downstream sites, apps and devices you could never reach individually.

• Data Axle Feeds bank, GPS and directory-assistance databases across the US.
• Foursquare Powers place data in Apple Maps, Uber, Samsung and X.
• Neustar / TransUnion Underpins caller ID and business-verification systems.
• GPS Network Reaches in-car navigation and connected-device maps.

This is the half most per-citation quotes leave out, and the half that keeps paying off after the order is finished.

A live listing on each, carrying your exact name, address, phone and a link back to your site.

About a dozen are directories people genuinely use and that carry weight on their own:

The rest are smaller directories that nobody browses, and we are not going to pretend otherwise. They earn their place for one reason: each is an independent source repeating your details identically. Volume of agreement is the signal, not the traffic.

This is where most citation building quietly goes wrong.

If a listing for you already exists with an old phone number, submitting a new one leaves two contradictory records and makes the problem worse. That is why the free check runs first: existing listings get corrected, duplicates get removed, and only genuinely missing listings get created.

You get the live URL for each listing that goes up, so this is verifiable rather than a claim.

Submissions run over days to weeks. That is normal: directories review manually and some require confirmation, and anything promising 50 live listings tomorrow is either lying or creating throwaway pages.
