A customer searches for a plumber and finds you in three places. One lists your old phone number. Another shows “Smith Plumbing LLC” and a third “Smith Plumbing and Heating”. One has the right address, one has a suite number you left two years ago.
That is a NAP problem. NAP means name, address, phone number. This guide explains why it matters, where to check, and how to fix it without spending a week.
Why consistency matters
Two reasons, one for people and one for machines.
For people. A wrong phone number is a lost call. A wrong address is a customer at the wrong building. If they find two different numbers, they may try the wrong one and give up.
For search engines. Local search combines information from many sources. When the same business appears with matching details in many places, the engine can be more confident it is one real business. When details clash, it has to guess. How much weight this carries compared with reviews, proximity and relevance is not published, so do not expect a single fix to move you up the map results. It is basic hygiene, and it supports your calls and reviews.
What counts as the same
Pick a canonical form for each item and use it everywhere.
| Item | Decide | Example (made up) |
|---|---|---|
| Name | Exact legal or trading name, with or without LLC, and the same punctuation | Test Plumbing |
| Address | Street format, suite format, abbreviations | 100 Sample Street, Suite 2 |
| Phone | One main number, written in one format | (555) 555-0100 |
| Website | One URL, with or without www, https | https://example.com |
| Hours | Same hours, same holiday closures | Mon-Fri 8-5 |
| Categories | Closest matching category for your trade | Plumber |
Example The values above are placeholders. Replace them with your own. Write them in a note and copy from it each time.
Do not add keywords to your business name to try to rank. Google’s guidelines say your name should reflect your real-world name, and stuffing it risks a suspension.
Service-area businesses and hidden addresses
Many trades work from a van or a home office and go to the customer. Google lets a service-area business hide its street address and show a service area instead. Some consequences:
- Keep the address hidden consistently. A directory that publishes your home address contradicts your profile.
- Some Google tools that look up businesses by Place ID may not return service-area businesses without a visible address. If you need a review link, the CID form of the link can work. Our review link builder accepts both.
- Name the same service area on every profile.
- Use a mailing address only where a directory demands a physical address, and keep it the same across them.
Where to check
Start with the places customers actually look, in this order.
- Google Business Profile. Your most valuable listing. Check every field.
- Your own website. Header, footer, contact page and structured data.
- Apple Maps (Apple Business Connect), Bing Places.
- Facebook, Instagram, LinkedIn business pages.
- Yelp and trade-specific directories.
- Data aggregators and directory networks. Many smaller sites copy from these.
- Industry bodies and chambers of commerce.
- Old listings. Former addresses and phone numbers that still appear. These are the worst offenders.
Search for your business name, your phone number and your old numbers and addresses in quotation marks, and note every place that shows something different.
Fixing it
- Write down the canonical details.
- Fix the biggest listings yourself: Google, Apple, Bing, Facebook.
- Claim or correct directory entries one by one, or use a listings service that pushes your details to many directories at once. Biz Up’s Social & Local Wizard does that for 70+ directories, on the AI Voice + Review Wizard and Complete plans.
- For listings you cannot edit, look for a “report an error” or “claim this business” option.
- Re-check in a month. Corrections take time to spread, and some sites resurrect old data.
The phone number decision
A common mistake is putting a different number on each directory or on tracking lines. Calls then split across numbers, and search engines see contradictions. A simpler approach is one main public number, kept on your own phone, with calls you cannot take forwarded to a receptionist or an AI behind it. Customers dial the number they found, and you control what happens next. See AI receptionist for plumbers for how forwarding works.
If you use a call-tracking number on ads, keep your main number on listings and the website, and ask your advertising partner how they handle it.
What this has to do with reviews
Reviews attach to your Google profile. If duplicates exist, for example an old listing and a new one, your reviews can split and customers see a smaller count than you have earned. Fix or merge duplicates through Google’s tools. Then follow the steps in how to get more Google reviews and how to reply to them.
A short checklist
- Canonical name, address, phone, website, hours and categories written down.
- Google Business Profile matches exactly.
- Website header, footer and contact page match.
- Apple, Bing, Facebook, Yelp match.
- Old numbers and addresses searched for and corrected.
- Duplicates removed or merged.
- Service-area setting is the same everywhere.
- Re-checked after a month.
