Local SEO

Updated 18 September 2026

Quick Answer

NAP (Name, Address, Phone) refers to a business's core identifying details, which must be listed identically across a website, Google Business Profile, and directories for local search to trust and rank the business consistently.

NAP vs. Google Business Profile — What's the Difference?

Why It Matters

  • Inconsistent details across different listings (e.g. 'St' vs 'Street', different phone formats) confuse search engines about which business is the real one, undermining local rankings.
  • It's also increasingly a signal AI tools use to confirm a business's identity and trustworthiness.

How It Works

  1. Business name, address, and phone number are established as a single, exact format.
  2. That exact format is used identically across the website, Google Business Profile, and every directory listing.
  3. Any variation is corrected to match, restoring consistency.

Key Takeaways

  • NAP consistency means identical business details across every platform.
  • Inconsistencies undermine both traditional local SEO and AI-driven search trust.
  • Small formatting differences (abbreviations, phone format) count as inconsistencies too.
