You've set up your Google Business Profile, you have a website, maybe you're on Yell and Checkatrade too. But you're still not appearing where you should in local search results. One very likely culprit is NAP inconsistency — and most business owners have never heard of it.
What does NAP stand for?
NAP stands for Name, Address, and Phone number. These are the three core pieces of information that identify your business online. When your NAP is consistent — meaning these details are identical across every place your business appears on the internet — Google has high confidence in your business and rewards you with better local rankings.
When your NAP is inconsistent — even slightly — Google sees conflicting signals and becomes less certain about your business. That uncertainty translates directly into lower visibility in Google Maps and local search results.
Think of it like this: if Google sees "Pete's Plumbing, 12 High Street, Manchester" on your website, but "Pete's Plumbing Ltd, 12 High St, Manchester" on Yell — those look like two different businesses to an algorithm. That confusion hurts your rankings.
Why does NAP consistency matter for local SEO?
Google's local search algorithm relies heavily on citations — mentions of your business across the web. Citations from trusted directories like Yell, Yelp, Checkatrade, and TripAdvisor act as votes of confidence for your business. The more consistent citations you have, the more Google trusts that your business is legitimate and well-established.
But here's the catch: inconsistent citations don't just fail to help — they actively hurt. Google's algorithm interprets conflicting information as a signal that your business data is unreliable, which reduces how prominently it will display your listing.
NAP consistency is one of the most cited local ranking factors in Moz's annual Local Search Ranking Factors survey, consistently appearing in the top ten signals that influence Google Map Pack rankings.
What inconsistency looks like — real examples
Most NAP inconsistencies aren't dramatic. They're small formatting differences that seem harmless but confuse Google's matching algorithm. Here are the most common types:
| What it looks like | Inconsistent version | Consistent version |
|---|---|---|
| Business name | Pete's Plumbing Ltd | Pete's Plumbing |
| Street abbreviation | 12 High St | 12 High Street |
| Phone format | 07700 000000 | 07700000000 |
| Old address | Unit 4, Business Park, Leeds | 22 Station Road, Leeds |
| Website URL | http://petesplumbing.co.uk | https://www.petesplumbing.co.uk |
None of these look like big deals individually. Collectively, they're a ranking killer.
If you've moved premises, changed your phone number, or rebranded in the last few years, there's a strong chance old details are still sitting on directories across the web. Google will keep finding them until you update every listing.
Where your NAP needs to be consistent
The following places all need to show identical NAP information. Work through this list:
Your own properties (highest priority)
- Your website — footer, contact page, and ideally in your LocalBusiness schema markup
- Your Google Business Profile
- Your Facebook Business Page
- Your Apple Business Connect listing
- Your Bing Places listing
UK business directories
- Yell.com
- Yelp UK
- Thomson Local
- FreeIndex
- Scoot
- Cylex UK
Trade-specific directories (if applicable)
- Checkatrade
- TrustATrader
- MyBuilder
- Rated People
- TripAdvisor (for hospitality)
How to audit and fix your NAP — step by step
This takes a couple of hours but you only need to do it once (plus periodic checks when anything changes).
Step 1: Decide on your canonical NAP
Before you change anything, write down the one definitive version of your name, address, and phone number. This is your canonical NAP — the single correct version everything else must match. Be specific about formatting: do you use "Street" or "St"? Do you include "Ltd"? Spaces in your phone number or not?
Step 2: Find everywhere you're listed
Search Google for:
- Your business name in quotes:
"Pete's Plumbing" - Your phone number in quotes:
"07700 000000" - Your address in quotes:
"12 High Street Manchester"
Work through the first two pages of results and note every directory where you appear. Also check the sites in the list above directly.
Step 3: Update every listing
Log in to each directory and update your NAP to match your canonical version exactly. This is tedious but necessary. Start with Google Business Profile, your website, and Facebook — these carry the most weight. Then work through the rest.
Step 4: Check for duplicate listings
Duplicate GBP listings are particularly damaging. If you find more than one Google Business Profile for your business, request that the duplicate be removed or merged via the GBP support form.
Allow 4–8 weeks for Google to recrawl all the updated listings and reflect the changes in your rankings. NAP consistency improvements don't show up overnight, but they're one of the most reliable long-term ranking improvements you can make.
