What are NAP citations?
A NAP citation is a mention of your business name (Name), address (Address) and phone number (Phone number) on a website that is not yours. A link is not required: a text mention without a link also counts as a citation.
There are two kinds. Structured citations live in business directories, with the details in fixed fields — think of Telefoonboek.nl or your Google Business Profile. Unstructured citations are loose mentions in, for example, a news article, a blog or the sponsor page of the local sports club.
Both kinds count. Structured citations are largely within your own control; unstructured citations are often more valuable precisely because they are harder to get and carry context.
Why do NAP citations count for local SEO?
Google wants to be sure a business really exists, really sits at that address and is really reachable on that number before it earns a spot in the Local Pack. Every consistent citation is an independent confirmation of those facts. The more often exactly the same details appear in trustworthy places, the more certain Google is about your business entity.
The reverse also holds: inconsistency hurts. An old address in one directory, a different phone number in another and a deviating business name on a third — Google then cannot determine which details are correct, and that uncertainty signal drags down your local ranking.
Important to know: citations are a foundation, not a growth engine. They will not lift you from position 8 to position 1, but without a consistent foundation your Google Business Profile, reviews and local content never reach their full potential. On top of that, AI assistants use the same directories as a source — inconsistent details lead to literally wrong answers about your business there.
Examples: Dutch directories that matter
Start with the basics that apply to virtually every Dutch business: your Google Business Profile, Bing Places, Apple Business Connect (Apple Maps), your Facebook and Instagram business pages and your Chamber of Commerce (KvK) registration. The latter is the source many directories pull their data from, so it has to be correct first.
Then the well-known Dutch business directories, such as Telefoonboek.nl, Openingstijden.nl and Cylex Netherlands. They are rarely big traffic sources, but they are the places where Google and AI systems cross-check your details.
Finish with industry-specific platforms, because those weigh heaviest for your sector: think Werkspot for construction and trades, TripAdvisor and Thuisbezorgd for hospitality, or ZorgkaartNederland for healthcare providers. You discover which directories are relevant to you by searching for your main service plus city and seeing which directories rank on page one.
Getting your NAP consistent in 4 steps
Step 1: define your canonical NAP. One spelling of your business name, address and phone number — exactly as in your Chamber of Commerce registration and your Google Business Profile — recorded in one document everyone uses.
Steps 2 and 3: inventory and correct. Search for your business name, your phone number and any old addresses to find existing mentions. Correct deviating mentions, remove duplicates and claim unclaimed profiles. Most directories offer a free claim or change procedure for this.
Step 4: maintain. Moving, or getting a new phone number? Update your website and Google Business Profile first, then work through your directory list. Schedule one fixed moment per quarter to check your most important mentions.
