NAP Consistency Audit: How to Check and Fix Your Business Listings

What is a NAP audit, and why bother?

NAP is local SEO shorthand for name, address and phone number. A NAP audit is the dull, valuable job of checking that those three details are identical everywhere your business appears online. Website footer. Google Business Profile. Facebook page. Yell listing. Companies House record. A directory you signed up to in 2019 and forgot.

It sounds trivial. It isn't, because the web remembers everything. Move offices, change your phone number or tweak the business name, and old versions linger in a dozen places. Customers find the wrong number. Google finds conflicting evidence. And you lose small, steady amounts of trust across hundreds of searches.

Why does consistency help?

Search engines try to work out which real-world business a listing refers to. When the name, address and phone number match across sources, that's easy, and confidence goes up. When they conflict, Google has to guess, and sometimes it guesses wrong, merging records, creating duplicates or showing outdated information.

Customers benefit too. A mismatched phone number means a missed call. A wrong address means a wasted trip. Consistency is, at heart, good customer service. The broader practice of managing these listings is covered in the guide to local citations and business information consistency.

What a NAP audit doesn't do

It doesn't guarantee higher rankings. It removes avoidable confusion and removes a drag on your local presence. Think of it as housekeeping that makes other work more effective.

Who should run the audit?

Anyone careful with detail. A business owner can do it, as can a marketing assistant or a local SEO consultant. It needs patience more than skill. The key is to work systematically, document what you find and keep the master record up to date afterwards.

Where do you start? Build the master record

Every audit begins with a single source of truth. Without one, you can't tell which listing is wrong, because you haven't decided what "right" is.

Spend time on this step. The rest depends on it.

What goes into the master record?

Your exact business name as shown on signage. The full address, including building, street, area, postcode and, if relevant, suite or floor. The main phone number. Your website address. Opening hours. Primary and secondary categories. A short description. And the email address you use for the business, if it appears in listings.

Write each exactly as you want it to appear everywhere, including punctuation, abbreviations and capitalisation. Decide whether you're writing "Street" or "St", "Road" or "Rd", and stick to it. Save it in a shared document that everyone who edits listings can access.

Match the real world

The master record should match your signage, your invoices and your official registration. If those disagree, fix the real-world mismatch first.

What do Google's guidelines say about the name and address?

Google's guidelines for representing your business set clear rules, and your master record should follow them. For the name, use the real-world name that customers know, as it appears on your storefront, website and stationery. Leave out taglines, store codes, hours, phone numbers, URLs, service descriptions and location details such as "near Soho". Legal suffixes and special characters are allowed only if you can provide real-world proof, such as signage or invoices, that shows them as part of the name.

For the address, it must be your actual, real-world location. P.O. boxes and remote mailboxes aren't acceptable, and virtual offices aren't eligible. A co-working space is eligible only if it has clear signage, receives customers during business hours and is staffed by your own team during those hours. If you need a suite or mailbox number, put the physical address on Address Line 1 and the suite on Address Line 2.

Why compliance belongs in the audit

A listing that's consistent but non-compliant, such as a keyword-stuffed name copied everywhere, spreads a problem rather than fixing it. Audit against the guidelines as well as against each other.

How do you find everywhere your business appears?

You can't fix listings you don't know about. Discovery is the part of the audit that most often turns up surprises.

Cast a wide net, then narrow it.

Which sources should you list?

Start with the ones you control: your website (footer, contact page, schema markup), Google Business Profile, Bing Places, Apple Business Connect, Facebook, Instagram, LinkedIn, X and any other social profiles. Then the official records: Companies House, your VAT registration if published, trade body or regulator registers, professional directories. Then general directories and aggregators, such as Yell and other UK business listings. Then industry-specific directories and review sites. Finally, mentions in local press, partner websites and supplier lists.

For each source, record the URL, the details shown, who owns the account and how to edit it. The result is a spreadsheet you'll use throughout the audit.

Use search to find hidden ones

Search for your business name, old names, old addresses and old phone numbers. Search for your postcode with your business type. Duplicates and outdated listings often appear in results you didn't know existed.

How do you check for old details?

Make a list of every previous name, address and phone number the business has used. Search for each in quotation marks, along with your current name. Pay particular attention to the previous address, because moves are the main cause of lingering errors, and to numbers you've retired.

Old details turn up in places like old press releases, supplier directories, partner pages and scraped listings. Add them to the sheet. Some you can edit, others you'll need to request changes on, and a few may not be worth chasing.

Don't forget your own site

Check headers, footers, contact pages, privacy policies, terms, schema markup, email signatures and PDFs. Your own site is the easiest place to get right and the most embarrassing to get wrong.

How do you compare listings against the master record?

With the list assembled, it's time to compare. This is the heart of the audit, and a spreadsheet makes it painless.

Be precise and record exactly what you see.

What does the audit spreadsheet look like?

One row per listing. Columns for the source, URL, login owner, name as shown, address as shown, phone as shown, website as shown, categories where relevant, whether each field matches the master, the nature of any mismatch, the priority and the action taken.

Use a simple code: match, minor difference or major mismatch. A minor difference might be "Street" versus "St". A major mismatch is a different number, an old address or a changed name. Colour-code the sheet so the problems stand out.

Record the account owner

Beside each listing, note who owns the login. Orphaned accounts under a former employee's email are a classic obstacle.

Which mismatches matter most?

Major mismatches first: wrong phone numbers, old addresses, changed names. These cause missed calls and wasted visits and give the strongest conflicting signals. Then differences in suite or unit numbers and categories. Then formatting differences, which usually matter least.

Prioritise by prominence as well. A mismatch on your Google profile or website matters more than one on an obscure directory that nobody sees. Fix the visible, authoritative sources first, then work down.

Beware of duplicates

If you find two listings for the same business on one platform, merging or removing the duplicate becomes the first task, because duplicates split reviews and confuse customers.

What mistakes make NAP data inconsistent?

Most inconsistency comes from a handful of causes. Knowing them helps you spot problems and prevent new ones.

They recur in nearly every audit.

Which changes cause drift?

Moving premises. Rebranding. Changing phone providers or numbers. Opening or closing a branch. Adding a suite number. Changing legal structure, such as incorporating. Each creates a moment when some sources update and others don't. Staff changes matter too: the person who set up the listings leaves, and nobody knows the logins.

The fix is a change checklist. Whenever one of those events happens, run through the master record and the source list and update each one. Don't rely on memory.

The move checklist

Update the website first, then the Google profile with matching evidence, then the major directories and social profiles, then the long tail. Record each update with a date.

Which formatting habits cause trouble?

Switching between "Ltd", "Limited" and no suffix. Inconsistent abbreviations. Using "&" in some places and "and" in others. Adding keywords to the name on some directories. Putting the suite number on the wrong line. Using different phone formats, with and without area codes or country codes. Adding tracking numbers on some listings and not others.

None of these is catastrophic, but together they create noise. Pick a standard format and apply it everywhere. For phone numbers, a consistent national format on UK sites, with a country-coded version in structured data, is a sensible approach.

Keep the name honest

Adding "Best Plumber in London" to a directory name to chase searches breaks Google's guidelines and creates a mismatch. Use the real name everywhere.

How do you fix mismatches in the right order?

Fixing in the wrong order wastes effort, because some sources feed others. A sensible sequence gets the biggest gains first.

Work from the centre outwards.

What's the best order?

First, your own website, including structured data, so the master record is visible and correct at the source. Second, your Google Business Profile, with evidence if you've changed anything sensitive. The guidance in Google Business Profile optimisation covers the profile in more detail. Third, other major platforms: Bing Places, Apple Business Connect, Facebook and similar. Fourth, high-visibility directories and industry sites. Fifth, the long tail of smaller listings and mentions.

Where a platform feeds data to others, such as data aggregators, correct it early so the fix spreads. Track each update in the sheet and note when you expect it to appear.

Change one thing at a time on Google

Large simultaneous edits to a verified Business Profile can trigger review. Make changes steadily, and record each one.

How do you handle listings you can't edit?

Some listings are claimed by someone else, abandoned or created automatically. Try the platform's "claim this listing" or "suggest an edit" process. If you can't prove ownership, contact the platform's support with evidence such as company registration and a document showing your address. For scraped or low-quality listings with no way to edit, weigh the effort against the benefit. A wrong number on a directory nobody visits may not be worth weeks of chasing.

Prioritise anything that's high-traffic, high-authority or that shows a wrong phone number. Those do the most harm.

How does your website support consistency?

Your website is the one place you fully control, and Google reads it as a primary source of business information. Getting it right gives every other listing something solid to match.

Check it carefully.

What should the website show?

The business name, address, phone number and opening hours in the footer and on the contact page, in the same format as the master record. A clear contact page with a map if appropriate. Structured data using the LocalBusiness or a more specific type, carrying the same name, address, phone number and website. And, for multi-location businesses, a page for each location with its own details.

Make sure the contact details are real text, not only inside images, so search engines and customers can read them. For mobile, use tap-to-call phone links. If you have several numbers, make clear which is the main one.

Test with a crawler

Crawl your site and search for the old name, address and number. Any hits are leftovers to remove, including in old blog posts, PDFs and metadata.

How does schema markup help?

Structured data describes the business in a machine-readable format. When the name, address, phone number and website in the markup match the visible text and your profile, you give search engines a clean, consistent signal. Mismatches between markup and visible content do the opposite.

If you're adding or updating markup, validate it and keep it in step with the master record. The guide to structured data for service business websites explains which types to use and how to test them.

What about phone numbers, tracking and multiple lines?

Phone numbers are where good intentions most often cause inconsistency. Call tracking, forwarding, multiple departments and mobile numbers all create variants.

A few principles keep them manageable.

What do Google's guidelines say about phone numbers?

According to Google's guidelines, phone numbers must connect to your specific location and be under your direct control. Use local numbers rather than central call-centre lines where possible, and premium-rate numbers are not acceptable. For a business with a staffed location, that means the number on the profile should reach that location.

That doesn't ban tracking numbers entirely, but it does mean your primary number should be a genuine line you control and that appears consistently across sources. Use tracking numbers as secondary numbers where the platform allows.

Keep the primary number stable

Changing your main number is expensive for consistency. If you must, plan the change as carefully as a move.

How do you handle several numbers?

Choose one main number for listings and use the same format everywhere. Add secondary numbers, such as a mobile or a department line, only where the platform has a field for them. Make sure each number is answered and, ideally, routes to a person.

If you use call tracking on your website for attribution, make sure the number swap doesn't replace your main number in structured data or in listings that crawlers see. A dynamic number inserted by script can create mismatches in cached or scraped copies. Document how your tracking works so you can explain any differences.

Test your own numbers

Call each one. Check it rings, who answers and what they say. A listing with the right number and no answer is almost as bad as the wrong number.

How do multi-location and service-area businesses handle NAP?

More locations mean more places for details to drift. Service-area businesses add their own wrinkles, because they hide the address on Google while still needing a consistent one elsewhere.

Plan for both.

How do you manage several locations?

Give each location its own master record, its own profile and its own page on the website, with a unique, local phone number and a distinct address. Keep the naming pattern consistent: Google's guidelines expect chains to use the same name across locations within a country, with limited exceptions. Maintain one spreadsheet with a tab per location, and a single owner responsible for each.

Audit them all on the same schedule, and watch for duplicates, especially where two branches share a building or an old branch has closed. Closed locations should be marked closed or removed, not left to confuse customers.

Don't copy and paste details

A single typo in a template can propagate across dozens of locations. Check each one.

What about service-area businesses?

Google's guidelines say service-area businesses should hide their address from customers and designate a service area, while other platforms may still need an address for verification or for their own listing requirements. Be careful about what you publish where. Where a directory shows an address, make sure it's the correct one and consistent with your records, and avoid listing a home address publicly if you don't see customers there.

Use the same service-area description across sources, and make sure it reflects the area you can realistically serve. Reflecting this on the website without creating thin pages is the job of well-built service area pages for London businesses.

Keep privacy in mind

If the address is your home, think carefully about where it appears. Hide it where you can, and keep consistent details where it must be shown.

How do you prevent drift after the audit?

A cleaned-up set of listings starts to decay immediately. People change numbers, platforms scrape and sync data, and new directories appear. A modest routine keeps the work from unravelling.

Treat consistency as maintenance, not a project.

What does a maintenance routine involve?

A quarterly check of the key sources: website, Google profile, Bing, Apple, Facebook and the top directories. A review of the master record whenever anything changes. An annual full audit of the whole sheet. A change checklist for moves, rebrands and number changes. And a named owner who holds the master record and the list of logins.

If you use a listing management service, understand what it covers and how to stop or change it. Some push data to many directories at once, which is helpful until you need to change something and discover you've lost the logins.

Protect the logins

Store credentials in a password manager, use business email addresses and record who owns each account. Orphaned logins are the biggest long-term headache in local listings.

Where does a specialist help?

When you have many locations, a history of moves and rebrands, a large number of duplicates or a profile that's been suspended or flagged, a specialist can save time and avoid mistakes. A local SEO consultant can build the master record, audit the sources, prioritise the fixes, handle claim requests and set up a maintenance routine, while a local SEO checklist for London businesses puts NAP in the context of everything else that supports local visibility.

For most single-location businesses, though, an afternoon with a spreadsheet, a clear master record and a methodical approach is enough to sort out the worst problems and put a routine in place.

What does a worked example look like?

A concrete example makes the process real. This one is hypothetical, built from common patterns, with illustrative details.

It follows a small business from muddle to a clean record.

What did the audit find?

A small London dental practice moved premises two years earlier and changed its phone provider at the same time. The owner had updated the website and the Google profile, but nothing else. A NAP audit found eleven listings with the old address, six with the old phone number, two duplicate profiles on a review site and a social page with the practice's former name.

A handful of calls to the old number were reaching a line that now belonged to someone else. A few patients had gone to the old address. And a supplier directory still listed the practice under a trading name it had dropped.

The real cost

None of it showed up in a dashboard. It showed up as missed appointments and confused patients, which is precisely the kind of cost audits reveal.

How did they fix it?

They wrote a master record from their signage and registration, then sorted the sheet by priority. They corrected the highest-visibility listings first, merged the duplicates, claimed the orphaned profiles and updated the social page. They contacted the supplier directory, which fixed its entry. For a few obscure listings with no edit route, they accepted the risk and moved on.

Finally, they added a change checklist to the practice manual, set a quarterly reminder and stored all logins in a password manager. Within a couple of months, the number of calls to the wrong line had dropped to nothing, and the profile's details matched the website, the directories and the building's sign. The work wasn't glamorous, but it removed a steady leak, and it made the next local SEO tasks, such as reviews and content, far more effective.

The takeaway

Decide what's true, find everywhere it's wrong, fix the highest-impact places first and set a routine so it stays right.

Which tools help with a NAP audit, and which are overrated?

You can run the whole audit with a spreadsheet and a browser. Tools make it faster, especially for many locations, but none replaces judgement. Knowing what each kind does stops you buying more than you need.

Start with the free options.

What can you do for free?

Search Google for your business name, old names, addresses and phone numbers. Check your Google Business Profile, Bing Places and Apple Business Connect directly. Use a site crawler to find old details on your own website. Look up your Companies House record. Browse the main UK directories by hand. That covers the sources that matter most for a typical small business.

Add a simple spreadsheet with a row per listing and colour-coded status, and you have an audit. It takes a few hours the first time, and much less once the master record exists.

A manual check beats an automated score

A tool's consistency percentage can hide the one mismatch that matters. Look at the actual rows.

What do paid listing tools add?

Some services scan dozens of directories, report mismatches and push corrections to many sites at once. They save time for multi-location businesses and agencies. They also have trade-offs: you may lose direct control of listings, the data they push can lag, and cancelling can leave you with listings you no longer manage.

Before you commit, ask what the service covers, which directories actually accept its updates, how to export your data and what happens to the listings if you stop paying. Treat the tool as an assistant, not a replacement for owning your own accounts. If you'd like help deciding, a specialist local SEO consultant can recommend what suits your situation.

Keep ownership of the key profiles

Never let a tool or agency hold the primary logins for your Google profile or website. Add them as managers, and keep the owner role yourself.

How do citations, reviews and consistency fit together?

NAP consistency doesn't work in isolation. It's one of several local signals, and understanding how they relate stops you from over-investing in one while neglecting the others.

Think of it as part of a system.

How do citations relate to NAP?

A citation is any mention of your business's name, address and phone number on another site, with or without a link. A NAP audit is really a citation audit with a focus on accuracy. Quality, relevance and accuracy matter more than raw quantity, which is why a handful of correct, well-chosen listings usually beats hundreds of duplicates.

The guide to local citations and business information consistency explains which directories are worth your time and how to find and fix inaccurate or duplicate listings.

Quality over volume

A correct listing on a respected site beats ten on obscure ones. Choose sources your customers and competitors actually use.

How do reviews and profile quality interact with NAP?

A consistent set of details makes your profile easier to trust, which in turn makes your reviews and photos more effective. Conversely, a profile with a wrong phone number or a mismatched address undermines the effort you put into reviews. The pieces support each other. A steady review routine, covered in the guide to getting more Google reviews, works best on top of clean, consistent details.

Treat the audit as the foundation and the rest as the building. A solid foundation doesn't win the race alone, but a cracked one slows everything down.
