NAP Consistency
Why NAP consistency matters and how to maintain it
NAP consistency is one of the top local SEO ranking factors. Inconsistencies confuse search engines and erode trust.
Why Consistency Matters
Search Engine Confusion
Google cross-references business data across sources. When it finds:
- "Main Street" in one place, "Main St" in another
- Different phone numbers on different sites
- Slightly different business names
It may:
- Trust your data less
- Rank you lower
- Show incorrect information
Real-World Impact
Case Study: A business moved locations but kept the same phone number. The inconsistent address across old citations caused them to drop from #2 to off the first page for 2 years.
Customer Experience
Inconsistent NAP leads to:
- Customers going to wrong address
- Calls to disconnected numbers
- Frustration and lost business
Types of Inconsistencies
Format Variations
Same info, different format:
- "123 Main Street" vs "123 Main St."
- "(555) 123-4567" vs "555-123-4567"
- "Company, Inc." vs "Company Inc"
Data Errors
Actual mistakes:
- Wrong suite number
- Transposed phone digits
- Misspelled street name
Outdated Information
- Previous addresses
- Old phone numbers
- Former business names
How Inconsistencies Happen
Historical Changes
- Business moved locations
- Phone number changed
- Rebranded or renamed
Automated Listings

- Directories auto-create listings

Human Error

Establishing Your Canonical NAP
Step 1: Define Your Standard
Create a master document with exact format:
Business Name: Joe's Plumbing Services LLC
Address: 123 Main Street, Suite 100, Chicago, IL 60601
Phone: (312) 555-1234
Website: https://www.joesplumbing.comStep 2: Use Google Business Profile as Source
Your GBP listing should be the authority. All other listings should match it exactly.
Step 3: Document Everything
Keep a record of:
- Exact formatting to use
- All platforms where you're listed
- Login credentials for each platform
