NAP consistency means your Name, Address, and Phone number appear exactly the same everywhere online — your site, Google Business Profile, and every directory. Even small differences ("St." vs "Street", a missing suite) confuse Google and weaken local rankings. For healthcare, it's one of the top local ranking factors.
Why a comma costs you rankings
Google builds confidence in your business by cross-referencing your details across the web. When listings disagree — different phone numbers, abbreviated streets, an old address — Google can't be sure which is right, so it trusts you less and ranks you lower. Consistency isn't pedantry; it's how the algorithm verifies you're a real, stable business.
Where inconsistencies hide
- Old addresses from before a move, still live on directories
- A tracking phone number on the website that differs from the profile
- "Dr." prefixes, suite numbers, and abbreviations applied unevenly
- Duplicate listings created over the years by staff or aggregators
- Auto-generated citations from data aggregators with stale info
Fixing it is an audit, then maintenance
Start with a citation audit across the major healthcare and general directories to surface every variant and duplicate. Standardise on one exact format, correct or claim each listing, and merge duplicates. Then maintain it — every time you change a number or move, update everywhere, because a single stale citation can quietly drag the whole profile.
A worked example
A practice that had relocated a year earlier still ranked poorly locally. The audit found the old address live on a dozen directories and two phone-number variants in circulation. Standardising every citation to one exact NAP and removing a duplicate listing restored Google's confidence, and local visibility climbed over the next couple of months.
Frequently asked questions
Does a tracking number break NAP?
It can, if it differs from your profile number across listings. Use call tracking that's consistent or implemented in ways that don't fragment your public NAP.
How many directories matter?
The major general and healthcare-specific ones — dozens, not hundreds. Prioritise the high-authority directories patients and Google actually reference, and keep those flawless.
