What Is NAP?
NAP stands for Name, Address, and Phone Number. In local SEO, NAP refers to how your business's core contact information appears across the internet — on your website, Google Business Profile, business directories, social media profiles, and anywhere else your business is mentioned online.
Why NAP Consistency Matters
Google uses your NAP information as a key signal to verify that your business is legitimate, credible, and accurately represented online. When Google sees your business name, address, and phone number consistently across multiple authoritative sources, it increases its confidence in the accuracy of your business data.
When your NAP is inconsistent — even in small ways — Google gets confused. It may see multiple different versions of your business and not know which is correct. This confusion negatively impacts your local search rankings and Local Pack visibility.
What Counts as an Inconsistency?
You might be surprised how small an inconsistency can be while still causing problems. Examples include:
- "123 Smith Street" vs "123 Smith St" vs "123 Smith Street, Suite 4"
- "0400 123 456" vs "0400-123-456" vs "(04) 00123456"
- "Blue Ring Marketing Pty Ltd" vs "Blue Ring Marketing" vs "Blue Ring Marketing PTY LTD"
- Using an old phone number in some places and a new one in others
- Using an old address after moving premises
Any of these variations can confuse Google's algorithm and dilute the authority of your local citations.
How to Audit Your NAP Consistency
Step 1: Establish Your Canonical NAP
Decide on the exact format for your business name, address, and phone number. This is your "canonical" or master NAP. Write it down and use it everywhere, consistently, forever.
Step 2: Check Your Core Properties
Start with the most important: your website (especially your footer, contact page, and any pages with your address), your Google Business Profile, and your Facebook business page.
Step 3: Search for Your Business Online
Google your business name and phone number separately. Look for all the places your business appears and check each one for accuracy.
Step 4: Check Key Australian Directories
Review your listings on Yellow Pages, True Local, Yelp Australia, Hotfrog, Aussie Web, StartLocal, and any industry-specific directories relevant to your business.
How to Fix Inconsistent NAP
For each inconsistent listing you find: log into the directory and update your information; if you can't edit the listing, contact the directory's support team; for old listings that can't be updated, use Google's Disavow process for any that might be causing harm.
This process can be time-consuming, but it's worth the effort. The improvement in local rankings can be significant.
Preventing Future NAP Issues
- Create a document with your canonical NAP and share it with any staff or agencies that manage online listings
- Before changing your phone number or address, plan a comprehensive update across all listings
- Set a quarterly reminder to audit your key directory listings for accuracy
- When getting press coverage or backlinks, always provide your canonical NAP to publishers
NAP Consistency as Part of a Complete Local SEO Strategy
NAP consistency alone won't get you to the top of Google. It's one piece of a larger local SEO puzzle that includes your Google Business Profile, reviews, on-page optimisation, backlinks, and content. But it's a foundational piece — and one that's entirely within your control.
Fix your NAP inconsistencies, then layer the other local SEO elements on top, and you'll build a strong foundation for local search dominance.
