- NAP = Name, Address, Phone — must be identical everywhere they appear on the site
- Inconsistencies confuse search engines and hurt local ranking
- Use identical formatting: same abbreviations, same phone format, same suite notation
- Reinforce NAP consistency in LocalBusiness schema markup
Rule Details
NAP stands for Name, Address, Phone. These three pieces of information must be identical across every page of your website, your Google Business Profile (opens in new tab), and external directory listings, especially when they also feed into LocalBusiness schema.
Code Example
Google cross-references business information from multiple sources to confirm a business's legitimacy and location. Inconsistencies — even minor formatting differences — create data confidence issues:
❌ Footer says: "123 Main St, Suite 4"
❌ Contact says: "123 Main Street, Ste 4"
❌ Schema says: "123 Main Street Suite 4"
✅ All should say: "123 Main Street, Suite 4" (pick one, use everywhere)Why It Matters
Inconsistent NAP information across a website signals to search engines that the business details are unreliable. That inconsistency can suppress local rankings and undermine the same entity confidence described in Schema.org PostalAddress (opens in new tab).
Common Inconsistency Patterns
| Element | Inconsistent | Consistent |
|---|---|---|
| Phone format | 555-123-4567 vs (555) 123-4567 | Pick one format |
| Street abbrev. | St. vs Street | Pick one |
| Suite notation | Suite 4 vs Ste 4 vs #4 | Pick one |
| Business name | Mario's Pizzeria vs Mario's Pizza | Exact match |
| State | IL vs Illinois | Pick one |
Where to Check
- Footer — most sites display NAP in the footer
- Contact page — dedicated contact information
- About page — often includes address and phone
- JSON-LD schema —
LocalBusinessorOrganizationmarkup - Google Business Profile — must match site exactly
- Page titles / headers for multi-location sites
Correct Implementation
<!-- ✅ Consistent NAP in HTML (footer) -->
<address>
<span itemprop="name">Mario's Pizzeria</span><br />
<span itemprop="streetAddress">123 Main Street, Suite 4</span><br />
<span itemprop="addressLocality">Springfield</span>,
<span itemprop="addressRegion">IL</span>
<span itemprop="postalCode">62701</span><br />
<a href="tel:+15551234567" itemprop="telephone">(555) 123-4567</a>
</address>// ✅ Matching JSON-LD schema
{
"@type": "LocalBusiness",
"name": "Mario's Pizzeria",
"address": {
"@type": "PostalAddress",
"streetAddress": "123 Main Street, Suite 4",
"addressLocality": "Springfield",
"addressRegion": "IL",
"postalCode": "62701",
"addressCountry": "US"
},
"telephone": "+1-555-123-4567"
}Multi-Location Sites
Each location should have its own dedicated page with that location's NAP:
/locations/springfield/ — Springfield NAP
/locations/chicago/ — Chicago NAPNever mix multiple location NAPs on a single page.
Audit Process
- Export all instances of your phone number from the site using a site-wide text search
- Export all instances of your street address
- Compare formats — create a canonical-url format document
- Update all pages to match the canonical-url format
- Update Google Business Profile to match
Exceptions
- Local SEO guidance only applies when the business actually serves a geographic area or has public location information relevant to searchers.
- Service-area businesses may need service-area guidance instead of storefront-focused address markup or location-page patterns.
- Do not invent addresses, business categories, or geographic claims to satisfy local SEO recommendations; accuracy overrides completeness.
Verification
Automated Checks
- Inspect rendered HTML and HTTP headers to confirm the expected metadata or crawlability signal is present.
- Test the affected URL with Google Search Console or equivalent tooling where relevant.
- Re-crawl a representative page set after deployment.
Manual Checks
- Confirm the change does not create conflicting canonical-url, robots, or structured-data signals.

Check
Verify implementation
Search the site for all instances of the business name, street address, and phone number. Compare each occurrence for exact consistency in spelling, formatting, and abbreviation (e.g., 'St.' vs 'Street', '555-1234' vs '(555) 123-4567'). Also check JSON-LD LocalBusiness schema against the visible text.
Fix
Auto-fix issues
Standardise all NAP occurrences to a single canonical-url format. Choose one format for each field: full street name vs abbreviation, phone number formatting, suite/unit notation. Update all pages, footer, contact page, about page, and structured data to match exactly.
Explain
Learn more
NAP consistency is a local SEO ranking factor. Google cross-references a business's Name, Address, and Phone across the site and external citations (Google Business Profile, directories). When these differ even slightly, Google's confidence in the data decreases, which can lower local rankings and show incorrect information in search results.
Review
Code review
Extract all instances of the business name, street address, and phone number from the site. Compare each instance for exact formatting consistency: same abbreviations (St. vs Street), same phone format, same suite notation. Extract the address from any LocalBusiness JSON-LD and compare against visible HTML text. Report any differences.
