NAP Consistency for Local SEO

Overview

NAP stands for name, address, and phone number. Google uses NAP data from across the web to verify the legitimacy and location of a business. When a contractor’s name, address, or phone number appears differently across Google Business Profile, the website, Yelp, Yellow Pages, and other directories, Google’s confidence in the business information decreases. This inconsistency suppresses local search rankings and can cause incorrect information to appear in search results.

Common Causes of NAP Inconsistency

  • business name abbreviated differently across listings (e.g. “GTA Plumbing Inc.” vs “GTA Plumbing” vs “GTA Plumbing & Heating”)
  • phone number changed without updating all directory listings
  • business moved to a new address but old address still appears on older directories
  • suite or unit number included on some listings but not others
  • different tracking phone numbers used across marketing channels without consistent handling

How the Problem Appears

  • Google Business Profile showing a different address than the website
  • older directory listings showing a phone number that is no longer in service
  • Google Maps displaying outdated information despite the GBP being updated
  • local ranking declining after a phone number or address change

How It Is Diagnosed

  • searching the business name in Google and reviewing all listed results
  • checking major directories (Yelp, Yellow Pages, HomeStars, BBB) for consistency
  • comparing the name, address, and phone on the website footer against the GBP
  • using a citation audit tool to surface all online mentions of the business

Typical Fix

  • establish a canonical NAP — a single agreed format for the business name, address, and phone number
  • update the Google Business Profile to match the canonical NAP exactly
  • update the website footer, contact page, and schema markup to match
  • claim and correct major directory listings one by one
  • set up a redirect or forwarding if old phone numbers are still active elsewhere

NAP in Schema Markup

The website should include LocalBusiness schema markup with the canonical NAP embedded in the page code. This gives Google a structured, authoritative source for the correct business information.

Technical Website Support

If NAP data is inconsistent across online listings and it is affecting local search rankings, a citation audit and correction across major directories can restore consistency and improve Google’s confidence in the business information.
