NAP consistency & local citations

NAP, short for Name, Address, Phone, is the structured business identity that local-search systems use to resolve "you" across multiple sources. Citations are mentions of your business on third-party sites that include some or all of your NAP. The direct ranking weight of citations has been declining for years; the entity-resolution work they do has not. Get NAP wrong and every other thing you do is fighting against fragmented, contradictory data. Get it right and the rest of your work compounds.

Why citations still matter, even though they "matter less"

You will read takes that citations no longer matter. Those takes are partly right: building 200 cheap directory listings is not a strategy. Industry ranking-factor surveys have shown citation count's direct ranking weight steadily decreasing for over a decade as Google has improved its entity-resolution capabilities. The work that used to be done by citation density is increasingly done directly by the Knowledge Graph, GBP, and structured data on your domain.

But citations still do useful work for two reasons:

Step 1: pick your canonical NAP

Before you audit anything, decide what your canonical NAP is. Be specific about format. Pick one and only one form of each component, then enforce it everywhere.

1. 1

   Decide your canonical Name

   Match Companies House (or your local equivalent) and signage. Pick "ABC Plumbing" or "ABC Plumbing Ltd", not both. If you trade under a different name (a "doing business as" trading name), decide which is canonical for your GBP and citations and stick with it. Document the decision somewhere that future team members will find.

2. 2

   Standardize the Address format

   Pick one format and use it everywhere: "Street" vs "St", "Road" vs "Rd", whether to include the building name, whether to include a unit number, capitalisation. Include the postcode in standard format with the space (in the UK, "SW1A 1AA", not "SW1A1AA"). Match Royal Mail's authoritative formatting where possible; Royal Mail's address database is one of the sources Google cross-references for UK addresses.

3. 3

   Pick one phone number, one format

   UK businesses should standardize on the +44 international form OR the local 0XX form, but not flip between them. Tracking numbers that vary by source destroy NAP consistency. If you must use them, ensure your canonical NAP is the only one indexed publicly, with tracking numbers served only to known traffic sources via dynamic insertion.

4. 4

   Document it as your single source of truth

   Write it down. Put it in your CMS, your team handbook, your onboarding doc for any agency you work with. Anyone updating any listing should reference this document. For multi-location businesses, this becomes a central database with one row per location, owned by a single person.

Good vs problematic NAP examples

Step 2: audit the directories that actually matter

You do not need 200 citation sources. You need 15 to 25 high-authority ones to be accurate, with the exact list depending on your country and sector. The list below is the realistic priority for UK local businesses; the principle applies across markets even where the specific directory names differ.

Step 3: hunt down duplicates

Duplicate listings are worse than incorrect ones. They split your reviews and prominence signals across two records that Google cannot easily merge. Common causes:

• You moved premises and the old address is still live on a directory somewhere
• You changed your business name (e.g. took on a partner) and the old name is still listed
• A previous occupant of your premises had a listing that is still indexed
• Two separate teams created listings on the same directory at different times
• A user-generated submission (someone other than you) created a duplicate
• An aggregator pulled stale data from a third-party feed and never refreshed it
• You added a service area to one listing without merging or removing a previous physical-address listing

Search Google for your business name with and without "Ltd", with and without your old address, with and without your old phone number. Anything that turns up needs to be either claimed and corrected, or formally requested for removal. For GBP specifically, Google has a "report duplicate" flow that works reasonably well if you have control of the canonical listing. For other directories, the removal process varies; expect each one to take weeks.

Step 4: fix the website itself

Your own website is also a citation. The most polished agency-built sites sometimes miss this because the NAP gets baked into a logo image, or a stylised footer that crawlers cannot easily parse. Make sure:

• The NAP appears on your homepage in plain text, not as an image
• It is wrapped in LocalBusiness JSON-LD schema markup with full property breakdown
• It is identical to the canonical NAP, same form, same punctuation
• It appears in your footer on every page
• If you have multiple locations, each has its own page with its own NAP and schema
• Phone numbers are clickable on mobile (tel: links)
• Address is geo-coded with latitude and longitude in the schema's geo property
• sameAs property in schema links to GBP, Wikidata if applicable, and major social profiles

Schema and the entity-convergence connection

NAP consistency is the visible surface of a deeper problem: entity resolution. When Google, Bing, Apple's data ingestion, and any AI assistant's underlying retrieval all read your NAP from multiple sources, they need to converge on a single canonical entity. Schema.org markup makes this faster and more reliable.

Add LocalBusiness JSON-LD to your homepage with a full property breakdown (street, locality, region, postcode, country, telephone, geo coordinates, opening hours, sameAs array). The sameAs array is the explicit declaration that all the listed URLs describe the same entity. Linking your domain to your GBP listing, your Wikidata Q-number if you have one, your Companies House page, and your major social profiles tells crawlers and AI systems "treat all these as one entity". This accelerates entity convergence on a new or rebranded business and reinforces it on an established one.

For multi-location businesses, each location page should have its own LocalBusiness schema with that location's specific details. The corporate homepage can use Organization schema linking out to all the location pages via hasPart or department relationships, depending on the legal structure.

See the AI search visibility (GEO) guide for the full entity-convergence playbook including Wikidata, sameAs strategy, and crawler access.

Common mistakes to avoid

The move/rebrand checklist

When a location moves or rebrands, work through this list before announcing the change publicly. Updating GBP first then catching everything else over weeks is the most common path to long-term inconsistency.

• Update GBP (name, address, phone, all on the same day)
• Update Bing Places
• Update Apple Business Connect
• Update website homepage, footer, contact page
• Update LocalBusiness schema on every page that includes it
• Update sameAs links to ensure they still point to current URLs
• Update Yell, Yelp, Facebook Page, LinkedIn
• Update second-tier directories from your initial citation audit
• Update sector-specific directories
• Update local council and chamber of commerce listings
• Update Google Search Console (verify new property if domain changed)
• Update Google Analytics property
• Update any active Google Ads location targeting
• Set up 301 redirects from old URLs if the site changed
• Notify your accountant to update Companies House
• Update any PR distribution lists
• Update internal documents: customer-facing letterheads, invoices, signatures
• Schedule a 30-day citation re-audit to catch anything missed

Cadence and ownership

For most established businesses, an annual citation audit is sufficient. The cadence increases for:

• Multi-location businesses (quarterly, with per-location ownership of any changes that have happened in that period)
• Businesses in rapidly-changing sectors where new sector-specific directories appear (some healthcare, professional services)
• Businesses that have recently moved, rebranded, or had ownership changes (re-audit at 30 days, 90 days, and 6 months after the change)
• Multi-brand or franchise businesses where local managers may have created additional listings without central oversight

Where to go next

With clean NAP and citation footprint sorted, the next leverage points are your GBP itself and your review pipeline. NAP is the foundation. GBP optimization and reviews are what compound on top of it.
