What Is NAP Consistency and Why Does It Matter for Local SEO?

NAP consistency refers to the uniformity of your business's Name, Address, and Phone number across every online platform where your business is listed — your website, Google Business Profile, Yelp, Facebook, Yellow Pages, industry-specific directories, and every other citation source. When search engines like Google crawl the web, they cross-reference this information to build a confidence score for your business identity. Even minor discrepancies — a missing suite number, an abbreviated street name, or a different phone format — can erode that confidence and directly impact your local search rankings.

According to Moz's Local Search Ranking Factors survey, citation signals (which include NAP consistency) account for approximately 13% of the local pack ranking algorithm. For businesses competing in dense local markets, this makes NAP accuracy one of the highest-leverage optimization targets available. Our NAP consistency checker focuses on the two most critical sources — your website and your Google Business Profile — because these are the primary data sources that search engines trust. If your website and GBP disagree on your business name, address, or phone number, every downstream citation built from either source inherits that inconsistency.

This free SEO NAP checker tool extracts your business information directly from your website's HTML and schema markup, simultaneously queries Google's Places API to retrieve your Google Business Profile data, and then performs a field-by-field cross-reference comparison — checking exact matches, partial matches, formatting differences, and missing data on both sides. The result is a scored report with specific, actionable recommendations for fixing every inconsistency found.

30+ Checks Across 4 NAP Audit Categories

Every aspect of your Name, Address, and Phone presence — analyzed and scored.

Website NAP Extraction

Extracts your business name, phone number, and address from JSON-LD structured data, microdata, HTML patterns, tel: links, footer content, and Open Graph tags. Detects multiple conflicting phone numbers and validates your schema markup type specificity.

Google Business Profile NAP

Fetches your live Google Business Profile data via the Places API. Verifies that your business name, phone number, address, and website URL are all set correctly on your GBP listing and that the website domain matches.

NAP Cross-Reference

Performs a field-by-field comparison: business name (exact, partial, and fuzzy matching), phone number (digit-level comparison with format normalization), and address broken down by street, city, state, zip code, and country — each scored individually.

NAP Best Practices

Evaluates schema type specificity, international phone format compliance, HTTPS security, click-to-call functionality, contact page linking, Open Graph tag presence, and phone format consistency between sources.

How NAP Inconsistencies Hurt Your Local Rankings

Citation Confusion

When your business NAP differs between sources, search engines cannot confidently associate all your citations with a single entity. This fragments your citation authority — instead of one strong listing, you appear as multiple uncertain ones.

Local Pack Demotion

Google's Local Pack algorithm uses NAP consistency as a trust signal. Businesses with perfectly consistent NAP across their website and GBP listing rank higher than those with discrepancies — even when other factors are similar.

Customer Trust Erosion

Beyond rankings, inconsistent business information confuses potential customers. If your website shows one phone number and Google shows another, customers question which is correct — and many simply move on to a competitor.

Who Should Use an SEO NAP Checker?

Any business that appears in local search results needs consistent NAP data.

Local Businesses

Restaurants, dental practices, law firms, plumbers, salons — any business serving a local area should run a NAP consistency check quarterly, or after any address, phone, or business name change.

SEO Agencies

Use our NAP checker tool as part of client onboarding to quickly identify citation inconsistencies. The exportable report demonstrates the exact problems and your value in fixing them.

Multi-Location Brands

Franchises and chains with multiple locations are especially prone to NAP inconsistencies. Run checks for each location's landing page to ensure every store has consistent, accurate data.

Web Developers

Validate LocalBusiness schema markup, verify tel: links, and confirm that NAP in structured data matches what's visible on the page — all before handing off a local business website to the client.

Frequently Asked Questions About NAP Consistency

Everything you need to know about NAP auditing for local SEO.

NAP stands for Name, Address, and Phone number — the three foundational pieces of business contact information that search engines use to identify and verify local businesses. NAP consistency means your business name, address, and phone number are identical across every platform where your business is listed, including your website, Google Business Profile, Yelp, Facebook, and industry-specific directories. Search engines cross-reference this data to build a confidence score for your business identity, making NAP consistency a critical local SEO ranking factor.

Our SEO NAP checker performs a three-step analysis. First, it fetches your website HTML and extracts business NAP data from JSON-LD structured data, microdata attributes, HTML patterns (tel: links, address tags), footer content, and Open Graph tags. Second, it queries Google's Places API to retrieve your Google Business Profile data. Third, it performs a field-by-field cross-reference — comparing business names (with fuzzy matching), phone numbers (with format normalization), and addresses broken down by street, city, state, and zip code. The result is a scored report with 30+ checks across 4 categories.

According to Moz's annual Local Search Ranking Factors survey, citation signals — which include NAP consistency and accuracy — account for approximately 13% of the local pack ranking algorithm. When your NAP differs between your website and Google Business Profile, search engines cannot confidently consolidate your citations into a single entity, fragmenting your citation authority. Businesses with perfectly consistent NAP across all sources rank significantly higher in Google's Local Pack than those with discrepancies, even when other factors are similar.

The most common causes include: business relocation without updating all listings, phone number changes, rebranding or legal name changes, different formatting conventions (e.g., "St" vs "Street", local vs international phone format), abbreviations in addresses, missing suite or unit numbers, and data aggregators distributing outdated information to hundreds of directories. Even a single inconsistency on a high-authority platform can create a cascade of conflicting data across the web.

Run a NAP consistency check at minimum quarterly, and always immediately after any changes to your business name, address, or phone number. Multi-location businesses should check monthly. After making corrections, wait 2-4 weeks for changes to propagate through Google's index, then re-run the check to confirm everything is aligned. Pro users can run unlimited daily checks to monitor NAP consistency during a citation cleanup campaign.

This free NAP checker focuses on the two most critical sources: your website and your Google Business Profile. These are the primary data sources that search engines trust most. If your website and GBP agree, downstream citations built from either source will inherit that consistency. For a comprehensive multi-directory citation audit (Yelp, Facebook, Yellow Pages, BBB, etc.), pair this tool with a dedicated citation management platform — but start here to fix the foundation first.

A score of 80-100 indicates excellent NAP consistency between your website and GBP, with all fields matching or only minor formatting differences. Scores of 60-79 suggest moderate issues — typically address formatting differences or a missing field on one source. Scores below 60 indicate significant NAP inconsistencies that are likely hurting your local rankings and should be fixed immediately. The most common fixes are aligning business name formatting, using the same phone number format, and ensuring your full address is present on both your website and GBP.
