NAP Consistency: Name, Address, Phone

Why NAP consistency matters, how to audit citations, and the systematic process for fixing inconsistencies.

Why Consistency Matters

Google uses NAP (Name, Address, Phone) as unique business identifiers. If your business appears as "Joe's Plumbing" on Google Business Profile, "Joes Plumbing" on Yelp, "Joe Plumbing Services" on a directory, and a different address on your website, Google questions whether these are the same business. Inconsistencies create confusion and suppress local rankings.

Consistency signals: this is a real, stable business. Inconsistencies signal: this data is unreliable.

Why This Matters

NAP consistency is one of the fastest ROI improvements in local SEO. Fixing inconsistencies can move you 2-3 positions in the local pack within weeks.

Audit Your NAP Data

Search your business name + city. Look at the first page results and note the business information shown. Check: Google Business Profile, Yelp, Apple Maps, Yellow Pages, industry directories, and your own website. Write down NAP as it appears on each.

Common inconsistencies: phone number format (555-123-4567 vs (555) 123-4567), address abbreviations (St vs Street, Suite vs Ste), trading name vs legal name, old phone numbers, new address not everywhere yet.

How to Fix Inconsistencies

Priority 1: Google Business Profile. Update it first and ensure it is accurate. This is your authoritative listing.

Priority 2: Major directories. Claim your listing on Yelp, Apple Maps, Yellow Pages, and any industry-specific directories. Update NAP to match GBP.

Priority 3: Website. Ensure your website footer, contact page, and structured data (LocalBusiness schema) all match your GBP data exactly.

Priority 4: Other mentions. Secondary directories and any other online mentions. Less critical, but fix when possible.

Data Aggregators

Services like Data Aggregators (Yext, Moz Local, etc.) push NAP data to hundreds of directories at once, maintaining consistency. For large businesses with many locations, these services save time. For small businesses, manual updates to major directories often suffice.

The Consistency Habit

When you move location or change phone number, updating NAP is not a one-time task. You need a system to audit and update all public instances. Set a quarterly reminder to audit NAP across major directories.

How This Connects

NAP consistency is about making sure Google recognises your business everywhere. Citations—your NAP mentioned across the web—amplify this signal. The next section covers how citations contribute to local SEO.
