What is NAP consistency?

NAP consistency means a business’s name, address and phone number appear identically everywhere they are published — the website, the Google Business Profile, directories and data aggregators. Inconsistent records make it harder for search engines to resolve them to one entity.

NAP consistency means a business’s name, address and phone number appear identically everywhere they are published — the website, the Google Business Profile, directories and data aggregators. Inconsistent records make it harder for search engines to resolve them to one entity.

The mechanism is entity resolution rather than a score: conflicting records create ambiguity about whether two listings describe the same business.

Legacy records are the usual problem. An old suite number or a disconnected number persists across aggregators long after the business moved.

The usual error

Where this goes wrong in practice

Chasing citation volume on low-quality directories. A hundred thin listings do less than a correct profile on the few sources that actually feed the ecosystem.
