NAP (Name, Address, Phone)

The consistent business information — name, address, and phone number — used across all online directories for local SEO.

Full definition

NAP consistency is a foundational element of local SEO. Search engines cross-reference a business's name, address, and phone number across local citations (Yelp, TripAdvisor, Yellow Pages, industry directories) to verify legitimacy and establish trust. Inconsistencies — different phone numbers, abbreviated vs. full street names, outdated addresses — create confusion and can suppress local rankings. Conducting a NAP audit involves checking all major citation sources and correcting discrepancies. Tools like BrightLocal, Moz Local, and Whitespark help manage citations at scale. NAP information should also appear on-page and be marked up with LocalBusiness schema for maximum clarity.

Real-world example

A chain of dental clinics discovers 38 listings with outdated phone numbers from a previous rebrand. Correcting all citations causes local pack visibility to increase 55% over 90 days.
