NAP Consistency
and Schema Alignment
Your name, address, and phone number is an entity signal — and it must be identical everywhere.
What It Is
NAP stands for Name, Address, Phone — the three core entity identifiers for a local business. When NAP is consistent across the website schema, GBP, directory listings, and social profiles, Google builds a confident entity model. When NAP is inconsistent — different phone formats, abbreviated versus full street names, old versus new address — Google's entity confidence drops, weakening local rankings, Knowledge Panel confidence, and AI search citation eligibility. Common inconsistency patterns include 'St.' vs 'Street', different phone formats, business name variations like 'Bob's Plumbing' vs 'Bob's Plumbing LLC', and old addresses still appearing in directories after a location move.
Why It Matters
Google's local entity model is built by aggregating signals from dozens of sources: the website, GBP, Yelp, Apple Maps, dozens of directory sites, and social profiles. Every consistent signal increases Google's confidence that all these references describe the same business. Every inconsistency introduces ambiguity. NAP consistency is the foundation of local entity authority — without it, all other local SEO work is built on an unstable foundation.
Common Causes
Understanding why this failure occurs is the first step to fixing it permanently.
Format Variations in Phone
Phone number appearing in different formats across sources: (555) 123-4567 vs 555-123-4567 vs +15551234567 — technically the same number, but different strings from Google's entity matching perspective.
Address Abbreviation Inconsistency
'St.' vs 'Street', 'Ave' vs 'Avenue', 'Ste' vs 'Suite' — abbreviation inconsistencies create separate string values that Google must resolve, reducing entity confidence.
Business Name Variations
'Bob's Plumbing' vs 'Bob's Plumbing LLC' vs 'Bobs Plumbing' — legal name vs DBA vs informal name variations appearing inconsistently across sources.
Stale Data After Business Changes
Old address or phone number still appearing in lower-authority directories after a business moved or changed its number — creating conflicting signals that Google must resolve.

Pro Tip
Create a one-page NAP Standard document for every local client.
Document the exact canonical business name, address (formatted exactly as it should appear in every citation), and phone number. Share it with the client and all team members — every future citation, schema update, or directory listing uses this document as the source of truth. It takes 10 minutes to create and prevents months of NAP drift. Store it in the client's shared folder where it's accessible without having to look up the GBP each time.
