What Is a NAP Audit?

A NAP audit is a structured check for mismatches in business name, address, and phone data across Google Business Profile, the website, and directories. It is not a citation theory lesson. It is a cleanup workflow that shows where trust breaks and what to fix first.

NAP stands for name, address, phone. The audit exists because local business data rarely lives in one place. Google says Business Profile information can come from your website, licensed third-party sources, user contributions, and Google's own systems.¹ When those sources disagree, the wrong version can keep resurfacing.

That is why a NAP audit is an entity-consistency task, not a formatting exercise. You are not just fixing commas or abbreviations. You are deciding which record is correct, then making every high-visibility surface match that record.

Google's local ranking guidance says complete and accurate business information helps Google match a profile to the right searches.³ For a local business owner, that means a NAP audit supports trust, relevance, and conversion at the same time.

This answer-first structure also matches how AI systems retrieve information. Ahrefs found AI Overviews on 57.9% of question queries, 46.4% of queries with seven or more words, and only 7.9% of local searches overall (Ahrefs, 2025).⁴ A direct operational page is more useful than a generic local SEO explainer.

If you need the broader profile context before the cleanup work starts, use the Google Business Profile guide and the local SEO guide.

What Should You Check First?

Start with the canonical business record, then compare Google Business Profile, the website, major directories, and duplicates against it. If the source of truth is wrong, every downstream fix is fragile. The order matters more than the number of listings you touch in one session.

The right NAP audit starts with one canonical record. For most businesses, that means the exact business name, primary phone number, street address, suite format, and primary landing page you want customers to use everywhere.

After that, work through the surfaces in this order:

1. Canonical record: confirm the business name, address, suite, phone, and preferred URL you want every other source to mirror.
2. Google Business Profile: compare the public listing against the canonical record because it is the most visible local surface.
3. Website: check the contact page, footer, schema markup, and every location page.
4. Major directories: update the citation sources that other platforms copy or trust first.
5. Duplicates and legacy listings: suppress or correct old records that keep stale details alive.

The website belongs early in the sequence because Google can crawl it and reuse that information in local results.¹ If your footer still shows an old tracking number or an old suite number, the mismatch is not really fixed.

Major directories come before long-tail listings because they influence the rest of the citation graph more strongly. BrightLocal reports that directories make up 37% of organic results for informational local-intent searches (BrightLocal, 2025).² That is a good reason to fix the records people and search engines actually see first.

If the profile is verified, Google Profile Strength can also surface missing data fields that deserve a second look.⁵ It is not the audit itself, but it is a useful quality check after you confirm the canonical record.

How Do You Fix NAP Mismatches?

Fix the source of truth first, then update Google Business Profile, the website, major directories, and legacy duplicates in that order. Verification matters because edits can be reviewed before they publish. The reader needs a repair sequence, not a random list of edits.

Once you find a mismatch, resist the urge to edit everything at once. The goal is to stop bad data from re-seeding the profile later.

Use this repair sequence:

1. Lock the source of truth. Write down the exact business name, address, phone number, suite format, and URL that should be used everywhere.
2. Correct Google Business Profile. Update the listing to match the source of truth, including any suite or unit details. If access is unclear, resolve that first through Google Business Profile verification.
3. Correct the website. Update the contact page, footer, and location pages. If the website keeps the old data, Google may keep finding the wrong version later.¹
4. Correct major directories. Update the biggest citation and review platforms before long-tail listings because they spread the most trust signals.
5. Remove or merge duplicates. Old listings with outdated phone numbers or old addresses can keep conflicting data alive.
6. Re-check the live surfaces. Look at the public profile, the website, and core directories again after the edits publish.

Google says Business Profile edits are usually reviewed in about 10 minutes, though some edits can take up to 30 days to go live (Google, 2026).⁶ That timing matters. A clean fix can still look incomplete for days if the profile edit is pending review.

When you review the website, pay attention to details that often get missed:

• Abbreviated street names that do not match the preferred format
• Old call tracking numbers still sitting in the footer
• Suite numbers missing from one page but not another
• Location pages that use one URL while the profile uses another
• Franchised or multi-location naming conventions that changed over time

Verification Checklist

After the fixes are live, confirm the cleanup in a way that mirrors how customers and Google discover the business:

• Search the exact business name and phone number to find stray duplicates
• Compare the public Google Business Profile against the contact page and footer
• Check the highest-authority directory listings again after they refresh
• Review reporting trends in Google Business Profile reporting
• Measure whether the cleanup supports better map visibility with the Visibility Score guide

A discovery search is a category-led query such as dentist near me or plumber open now, not a search for your business by name. That is where clean business data has to hold up.

What Causes NAP Drift?

NAP drift usually comes from stale records, duplicate listings, moved locations, old phone numbers, inconsistent formatting, and third-party data lag. Google can compile profile information from multiple sources, so small errors spread unless the canonical record stays clean and consistent across every important surface.

Most businesses do not create NAP drift on purpose. It usually appears after a move, a rebrand, a new call-routing setup, or a website update that did not reach every page.

The most common causes are:

• Moved locations: the business address changes, but old directory records remain live
• Phone changes: a tracking number replaces the primary line on one surface but not everywhere else
• Suite drift: one listing says Suite 200, another says Ste 200, and another omits it completely
• URL changes: the website migrates, but the profile or directories still point to the old path
• Duplicate listings: legacy records keep the wrong address or phone number visible
• Third-party data lag: a data supplier or directory takes longer to refresh than the profile or website

Google's own help documentation explains why drift is persistent: profile information may be updated from crawled web content, licensed third-party data, user contributions, and Google interactions.¹ If one high-visibility source stays wrong, the profile can inherit that bad data again.

This is also why "more citations" is the wrong goal when the core record is unstable. Accuracy matters more than volume. A clean Google Maps optimization guide depends on stable business data before it depends on more distribution.

Keep a short internal change log every time the business moves, changes a phone line, updates hours, or changes location pages. That turns future audits into maintenance instead of emergency cleanup.

What is a NAP audit?

A NAP audit is a check for mismatches in your business name, address, and phone number across Google Business Profile, your website, and directory listings. The point is to find the canonical record, compare every major surface to it, and fix the conflicts in the right order.

How do I check NAP consistency?

Start with one correct record, then compare Google Business Profile, the website footer, contact page, location pages, major directories, and duplicate listings against it. Check the exact business name, address, suite format, phone number, and URL every time.

How do I fix a NAP mismatch?

Correct the source of truth first, then update Google Business Profile, the website, major directories, and duplicates in that order. Re-check the public profile after the edit review clears because some Google changes can take time to publish.⁶

Why does my address keep changing on Google?

Google may source profile information from your website, third-party providers, user contributions, and other Google systems.¹ If one of those sources still carries the wrong address, the mismatch can return even after you edit the profile.

Does NAP consistency still matter?

Yes. Google says accurate business information helps match a listing to relevant local searches.³ Clean NAP data also reduces customer confusion, makes directories more trustworthy, and gives your local visibility a stronger foundation before reviews, content, and conversion work take over.

NAP consistency is not glamorous, but it is one of the few local SEO tasks that directly affects trust across every major surface. If you want to measure whether your business data is aligned with real discovery demand, Get Your Visibility Score -- Free.
