NAP Citation
NAP stands for Name, Address, and Phone number — the three fields that identify a local business. A NAP citation is any mention of those fields across the web: directories, review sites, social profiles, articles. Google judges a local business's trust and prominence by how consistent its NAP is across all these sources.

Why It Matters
BrightLocal's 2025 local search ranking factors study places NAP citation volume, quality, and consistency among the top 5 signals for local pack rankings. Google pieces together scattered business listings from Google Business Profile, Apple Maps, Yelp, chamber of commerce sites, and more to decide "does this business really exist, and where is it?" Consistent NAPs build trust; inconsistencies make Google see the same business as multiple entities or tank its ranking.
Types of Citations
Structured citations: NAPs entered into the structured fields of business directories — Google Business Profile, Apple Maps, Yelp, Facebook Business Page. These carry the most ranking weight.
Unstructured citations: NAPs mentioned naturally in blog posts, news articles, and forum comments. Less powerful individually but still contribute to trust and brand recognition.
Mainstream directories: High-traffic platforms like Google, Apple, Facebook, Instagram.
Industry-specific directories: Category-specific platforms like TripAdvisor for restaurants or Avvo for lawyers.
NAP Consistency Rules
Name: Standardize the legal and brand name. Mixing "Inblog Inc.," "inblog," and "In Blog" can register as separate businesses.
Address: Unify building, floor, and suite formatting. "123 Teheran-ro, 5F Suite 501, Gangnam-gu, Seoul" vs "123 Teheran-ro-5F" may not auto-match.
Phone number: Standardize country code, area code, and separators. Mixing "+82 2-1234-5678" with "02-1234-5678" weakens matching.
Website URL: Unify www/non-www and HTTPS so every directory uses the same canonical URL.
Management Strategy
1. Define a master record: Document the canonical legal name, address, phone, and URL, and use the exact same format on every platform.
2. Prioritize major directories: Start with Google Business Profile, Apple Maps, Bing Places, and the largest country-specific platforms.
3. Audit regularly: Tools like Yext, BrightLocal, or Whitespark audit NAP consistency monthly. Manual checks can be done by Googling the business name and phone.
4. Update everything at once when things change: Address or phone changes should sync across all directories simultaneously to minimize inconsistency windows.
5. Merge duplicates: Request merges or deletes of duplicate profiles. Duplicates are the biggest source of NAP confusion.
Relationship with Structured Data
Providing NAP in Schema.org LocalBusiness or Organization markup signals Google that your site is the canonical source of truth. The more external directories match your schema, the more trust compounds.
