If your business details are slightly different depending on where Google finds them, that’s a problem. Not a dramatic, site-crashing problem. A quiet, invisible one that chips away at your local rankings without you knowing.

This is what NAP consistency means, why it matters and how to check yours in about 20 minutes.

What is NAP Consistency and why does it matter?

NAP stands for Name, Address and Phone number. It’s the basic identifying information Google uses to verify that your business is real, legitimate and located where you say it is.

When Google crawls the web and finds your business mentioned in directories, on review sites and across social platforms, it cross-references those mentions. If the details match up consistently, that’s a trust signal. If they don’t, Google has to make a judgement call about which version is correct. That uncertainty can push you down in local results.

It’s not just Google either. Customers who find conflicting information lose confidence quickly. A wrong phone number or an outdated address is enough to send someone elsewhere.

For businesses trying to show up in the Google Local 3-Pack, NAP consistency is one of the foundational things to get right before worrying about reviews or backlinks.

What counts as an inconsistency?

More than you might think. Common examples:

  • Business name variations — “Design by Nadja” vs “Design By Nadja” vs “Nadja Design”
  • Address formatting — “15 High Street” vs “15 High St” vs “15 High St.”
  • Phone number format — “020 1234 5678” vs “02012345678” vs “+44 20 1234 5678”
  • Old addresses — listings that never got updated after a move
  • Duplicate listings — two entries for the same business on the same directory, often with different details

None of these look serious in isolation. Collectively, they give Google a muddled picture of your business.

Step 1: Define your master NAP

Before you audit anything, decide on the exact format you want to use everywhere and write it down. This is your master NAP.

Be specific. If your business name has “Ltd” at the end, include it everywhere or exclude it everywhere. If you write “Road” on your website, don’t use “Rd” in directories. Choose a single phone number format and stick to it.

Save this as a simple text document you can copy and paste from. That single habit eliminates most inconsistencies before they happen.

Step 2: Check the platforms that matter most

Start with the highest-priority platforms. These carry the most weight with Google and are the most commonly wrong:

  • Google Business Profile — log in and verify your details exactly match your master NAP
  • Bing Places — now at bing.com/forbusiness after a full platform relaunch in October 2025. Particularly important because Bing Places is now the primary data source for Microsoft Copilot and ChatGPT, which use Bing’s index to answer local questions Thryv. If your details are wrong here, AI assistants will give people the wrong information about your business.
  • Apple Maps — manage your listing at businessconnect.apple.com. Apple is launching Apple Business on 14 April 2026, which consolidates Apple Business Connect into a single free platform. Existing Business Connect data will automatically migrate Rankability, so your listing should carry over but is worth checking after the changeover.
  • Facebook — check your About section, not just your page name
  • Your own website — your contact page, footer and any schema markup should all match

These five will cover the majority of your search visibility. Get these right first.

Step 3: Check the main UK directories

Once your core platforms are consistent, work through the directories that carry real weight for UK local SEO. The key ones to cover are Thomson Local, FreeIndex, Scoot (which syndicates to six directories), 192.com, Yelp UK and Trustpilot. BrightLocal

Search for your business name on each one. If you find a listing, check the details against your master NAP and update anything that’s off. If you find duplicate listings on the same platform, contact the directory to have one removed.

A note on Scoot specifically: because it syndicates your details to other directories automatically, getting it right there saves you work elsewhere.

Step 4: Search Google for stray mentions

This is the manual version of what citation tools do automatically, and it works well enough for most small businesses.

Search Google for your business name in quotes: “Your Business Name”. Then search for your old phone number, your old address and any previous trading names.

Look at what comes up on page one and two. Note anything that doesn’t match your master NAP. Some listings you can edit yourself. Others you’ll need to submit a correction request for. Keep a simple spreadsheet as you go so nothing gets missed.

Step 5: Use a tool to catch what you missed

For a more thorough sweep, a tool will save you hours of manual searching.

BrightLocal’s Citation Tracker pulls in citation information from across the web and performs a full NAP consistency audit, flagging errors and duplicate listings that need attention. It’s available on a 14-day free trial with no card required, which is enough time to run a full audit and work through any issues you find.

If you just want to build or fix specific listings without a subscription, BrightLocal’s Citation Builder is a pay-as-you-go service with a free account. It scans for existing citations automatically and lets you select which listings to fix or create.

You don’t need ongoing monitoring at this stage. Run the audit, fix what’s flagged and set a reminder to check again in three to six months.

What to do if you find problems

Work through them systematically, starting with the platforms in Step 2. Log into each directory and update your details to match your master NAP exactly.

For listings you can’t edit yourself, most directories have a “suggest an edit” or “claim this listing” option. Some take a couple of weeks to process changes, which is normal.

If you find a listing you’ve never created, that’s not unusual. Directories often pull data from aggregators and create entries automatically. Claim the listing so you can manage it going forward.

Don’t try to fix everything in one afternoon. Prioritise the high-authority platforms first and work down the list over a few weeks.

How often should you audit?

For most businesses, checking your NAP consistency once every three to six months is enough. The exceptions are:

  • If you move premises
  • If you change your phone number
  • If you rebrand or change your trading name

Any of those changes means updating every listing as a priority, not something to get round to eventually.

A note on schema markup

Your website itself should also confirm your NAP to Google clearly. Adding LocalBusiness schema to your site means Google can read your business details in structured form rather than trying to interpret them from your page content.

It’s not a replacement for consistent citations but it reinforces the same information and reduces any ambiguity about where your business is based and how to contact you. If you use WordPress, your SEO plugin handles this without any coding.
