What actually counts as NAP inconsistency
Every local SEO guide tells you NAP consistency matters. Almost none of them tell you what counts as inconsistent, which leaves people either ignoring it entirely or spending a day changing "Street" to "St" across forty directories for no benefit.
Both are wasted effort. Here's the distinction that actually matters.
The thing being solved
The purpose of consistency isn't tidiness. It's that a search engine is trying to work out whether the business on Yelp and the business on Bing are the same entity. Every matching signal makes that easier. Every genuine contradiction makes it harder, and a business it can't confidently resolve is one it will rank less confidently.
So the test for any variation is: would this make it harder to tell these are the same business?
Apply that and most of the anxiety falls away.
Differences that don't matter
Search engines have been normalising addresses for two decades. They are extremely good at it.
- "Street" vs "St", "Avenue" vs "Ave", "Suite" vs "Ste" — normalised. Not worth an afternoon.
- "(941) 555-0142" vs "941-555-0142" vs "941.555.0142" — the digits are identical. Normalised.
- Upper case vs title case.
- A trailing period, an Oxford comma, a line break in a different place.
- "WA" vs "Washington".
If a citation audit tool flags these as errors and counts them toward a score, it is inflating its own findings. That is a sales tactic, not a diagnosis.
Differences that genuinely matter
A different phone number. This is the big one. Two different numbers is not a formatting variation — it's a contradiction, and it's the single most common real inconsistency. It usually arises from a tracking number on one listing, an old number that was never updated, or a mobile on one directory and a landline on another.
Tracking numbers deserve their own warning: if you use call tracking, the number on directory listings should stay the primary number. Use dynamic number insertion on the website instead, where it doesn't touch citations.
A different street address. Not "St" versus "Street" — a genuinely different address. Almost always an old premises that was never updated after a move.
A missing or added suite number. Borderline, and worth fixing when convenient. Google treats a suite as part of the address, and in a shared building it's what separates you from six other businesses. Not urgent unless the building is shared.
A materially different business name. "Paint Gunners" and "Paint Gunners LLC" are fine — the legal suffix is understood. "Paint Gunners" and "Seattle Paint Gunners" is not, because the second contains a location keyword the first doesn't, and that's the kind of variation Google has explicitly discouraged for years.
Name variations that came from different people. "PaintGunners", "Paint Gunners WA", "Paint Gunners Painting" — these are how duplicate listings get created in the first place, and they're a signal that more than one person has been submitting listings without a shared source.
The ordering
If you're deciding where to spend an hour:
- Phone number contradictions. Every time. A wrong number costs the client calls today, quite apart from any ranking effect.
- Wrong addresses. Same reasoning — someone drives to the wrong place.
- Name variations that add keywords or locations.
- Suite numbers, if the building is shared.
- Everything else, which is mostly formatting and mostly not worth it.
Notice that the top two matter for reasons that have nothing to do with search. That's usually the tell for what's worth fixing.
Which listings to check
Not all of them. The ones that get seen.
Google, Bing and Apple feed maps and voice results. Yelp, Facebook and Better Business Bureau get direct traffic and are widely copied. Whatever directory dominates the vertical — Angi and Houzz for trades, TripAdvisor for hospitality, Avvo for legal — carries the most weight in that niche.
Beyond that you're into the long tail, where a listing might be seen by nobody but still contributes a matching signal. Worth having correct; not worth auditing monthly. Which ones are actually worth building in the first place is a separate question.
Categories count too
Name, address and phone get the attention, but the category a business is listed under is answering the same question — what is this business — and giving three different answers across three directories weakens it the same way.
Doing this without losing a day
The honest problem with NAP auditing is that it's tedious and it never stays done. A client changes their number, a directory syndicates an old record, someone creates a listing without asking, and you're back where you started.
Two habits make it manageable.
Keep one canonical version of the name, address and phone somewhere everyone submitting can see. Not in an email signature, not on an invoice template. One record, agreed once.
Search by fingerprint, not by name. The phone number in quotes finds the listings that carry it. The old phone number in quotes finds the ones that haven't caught up. That single query surfaces more real problems than a directory-by-directory crawl, and it takes seconds.
That's the whole premise of Placemark: hold the correct version once, and let something else go and find what disagrees with it. Free for one business, no card.
