NAP
Name, address and phone number.
What NAP does not show
Its value is consistency across every place the business appears, so the failure mode worth measuring is disagreement between sources rather than absence from any one.
How CrawlCheck measures NAP
2 finding codes measure it. Each one’s share of all scans is computed from the live corpus when this page is served, not typed into it.
| Finding code | Share of scans | Guide |
|---|---|---|
NAP_NAME_DRIFT | 0.7% | How to find websites using your brand name, and prove you were first |
NAP_UNDECLARED_LISTING | 4.2% | NAP consistency: how to check your name, address and phone |
Every code, its rule and its current rate: the dataset page. Scan a site to see which apply to it.
