- NAP stands for Name, Address and Phone number, the core contact details Google uses to identify and trust your business.
- A citation is any online mention of your NAP, on directories, review sites or social profiles.
- Consistency is everything: your NAP must match exactly everywhere, or conflicting listings confuse Google and hurt rankings.
- Clean, consistent citations are a foundational local ranking signal that works alongside reviews and your profile.
NAP means your business Name, Address and Phone number, and a citation is any place online where those details appear. Getting them consistent across the web is one of the quiet foundations of local SEO: when Google sees the same information everywhere, it trusts your business, and that trust helps you rank in local search and Maps.
What NAP and citations actually are
These are the building blocks of your local identity. Your NAP is the trio of Name, Address and Phone that identifies you, and a citation is any online mention of that trio, whether on a big directory, an industry site, a review platform or a social profile. Some citations link to your website and some do not, but each one is a data point Google cross-checks to confirm your business is real and located where you say. They work hand in hand with your Google Business Profile, which our guide to listing your business on Google Maps covers.
NAP = Name, Address, Phone number. A citation = any online listing or mention that displays your NAP, with or without a link to your site.
Why consistency matters so much
The single most important rule is that your NAP must match everywhere. If one directory lists an old address, another an abbreviated street name and a third a former phone number, Google receives conflicting signals and cannot be sure which is correct. That uncertainty erodes trust and can hold back your rankings. Identical details across every listing, down to formatting, remove the doubt and reinforce that your business is legitimate and stable. Inconsistent NAP is one of the most common reasons a business underperforms locally, as our guide on why a business does not show up on Google explains.
Conflicting NAP details across listings confuse Google and weaken rankings. Exact consistency everywhere is the fix, and it costs nothing but attention.
Where citations come from
Citations build up across several tiers. Core ones sit on major directories and data aggregators that feed information across the web. Others come from industry-specific and local sources: a chamber of commerce, a trade association, a regional listing site. And your own website, social profiles and Google Business Profile all count too. The aim is broad, accurate coverage, not sheer volume, so a handful of consistent, authoritative citations beats dozens of sloppy ones. Understanding how these mentions connect to Maps is covered in our guide to Google Map citations.

How to keep your citations clean
Start with an audit. Search for your business and note every listing, then correct any with outdated or mismatched details so all of them show one identical NAP. When you move, change your number or rebrand, update every citation, not just your Google profile, or you reintroduce the very inconsistency you cleaned up. Decide on one exact format for your name, address and phone, and use it everywhere going forward. Citations are foundational, but they sit within the broader local picture our guide to ranking in the local 3-pack lays out, where reviews and a complete profile do the rest.
Bottom line
NAP and citations are the plumbing of local SEO: your Name, Address and Phone, repeated accurately across the web. The work is not glamorous, but it matters, because consistent listings tell Google your business is real and trustworthy, while conflicting ones hold you back. Audit your listings, fix the mismatches, keep one exact format everywhere, and update them whenever anything changes. Then let reviews and a strong profile turn that solid foundation into visibility.
What does NAP mean in local SEO?
NAP stands for Name, Address and Phone number, the core contact details that identify your business online. Google uses them to confirm your business is real and located where you claim. Keeping your NAP accurate and identical across every listing is a foundational local ranking signal, working alongside your Google Business Profile and reviews to help you appear in local search and Maps.
Why does NAP consistency matter?
Because conflicting details confuse Google. If one listing shows an old address and another a former phone number, Google receives mixed signals and cannot be sure which is correct, which erodes trust and can hold back your rankings. Identical NAP across every citation removes that doubt and reinforces that your business is legitimate and stable. Inconsistency is a common cause of weak local performance.
What counts as a citation?
A citation is any online mention of your NAP, whether on a major directory, an industry or local site, a review platform, a social profile, or your own website. Some link to your site and some do not, but each is a data point Google cross-checks. The goal is broad, accurate coverage: a few consistent, authoritative citations are worth more than many sloppy ones.
How do I fix inconsistent citations?
Start by searching for your business and listing every place it appears. Correct any listing with outdated or mismatched details so all show one identical NAP, in a single consistent format. Whenever you move, change your number or rebrand, update every citation, not just your Google profile. Regular audits keep your listings clean and prevent the inconsistencies that quietly hurt local rankings.
