NAP Consistency
NAP consistency means keeping your business Name, Address, and Phone number identical everywhere they appear online, a trust and identity signal that matters for local and AI visibility.
Also known as: NAP
NAP consistency is using the exact same Name, Address, and Phone everywhere. Your business details should match character-for-character across your site, Google Business Profile, directories, and review sites — because inconsistent details make it harder for systems to confirm you're one real, trustworthy entity.
It's a long-standing local-SEO signal that carries straight into AEO. Consistent NAP is a form of corroboration: when every source agrees on your basic facts, engines trust them and can confidently state them, supporting the authority and credibility pillars. Conflicting addresses or phone numbers, by contrast, create doubt that can suppress how and whether you're recommended — especially for local questions.
Example. If your address is "123 Main St, Suite 200" on your site but "123 Main Street #200" on a directory and a third variant on Yelp, you've muddied your identity. Standardizing all three to one exact format removes that ambiguity.
