NAP stands for name, address and phone number. Google uses it to confirm a business is real and where it operates. Here is why consistency matters.
NAP stands for name, address and phone number. It is the core set of details Google uses to confirm your business is real, work out where it operates and decide whether to trust it enough to show in local results.
The reason SEOs go on about it is consistency. Google cross references your details across dozens of sources, and every version that disagrees chips away at its confidence.
How Google uses it
Google builds a picture of your business from your Business Profile, your website, directories, review sites, social profiles and news mentions. When those sources agree, the business looks established and real. When they disagree, Google has to guess which version is correct.
Guessing costs you. In the worst cases it creates duplicate listings, splits your reviews across two profiles, or sends customers to a phone number you gave up three years ago.
What counts as inconsistent
Less than you would hope. Suite 4 versus Ste 4. 0161 496 0000 versus +44 161 496 0000. Road versus Rd. A trading name on one directory and the registered company name on another.
Google is reasonably good at resolving small formatting differences now, so a Street versus St mismatch will not sink you. What genuinely causes problems is substantive disagreement: two different phone numbers, an old address still live on a dozen directories, or a business name that changed after a rebrand and only got updated in half the places.
Where your NAP needs to be right
- Google Business Profile. The source of truth. Everything else should match this exactly.
- Your website footer and contact page. Marked up with LocalBusiness schema so machines can read it without parsing your layout.
- The major aggregators. In the UK that means Yell, Thomson Local, the Bing and Apple business listings, and Companies House if you are registered.
- Industry and local directories. Your trade body, your chamber of commerce, anywhere with genuine visitors.
Cleaning up a messy NAP
Start by finding out how bad it is. Search your phone number in quotes, then your old address in quotes, and see what comes back. A citation audit tool will do it faster, but the manual version costs nothing and often turns up listings the tools miss.
Then fix in order of importance: Google first, the major aggregators second, everything else after. Aggregators feed data to smaller directories, so correcting one source often cleans up several downstream listings by itself.
One warning on moving premises. Change the address everywhere in a tight window rather than piecemeal. A slow migration leaves both addresses circulating for months, which is worse than either one on its own. Our search team handles this as a single sequenced job whenever a client relocates.
Common questions
Does NAP consistency still matter?
Yes, though less than it did a decade ago. Google is better at reconciling minor differences, so the payoff now comes from removing real contradictions, not from chasing perfect formatting across 200 directories.
What if I work from home?
Register as a service area business and hide the address. You still need a real one for verification, but customers see a service radius instead. Never use a virtual office, which risks suspension.
Should I use a call tracking number?
You can, as long as the main number on your Business Profile stays the one that appears on your website. Google allows a tracking number as the primary with the real number as secondary, but the simplest safe setup is to keep your genuine number everywhere public.
