How do you build entity authority through consistent NAP data?

NAP consistency – the same name, address, and phone number across every place a business appears online – is one of the most basic and most frequently broken entity signals, particularly for local and multi-location businesses. The mechanism is straightforward: when Google and the AI engines see identical NAP data across the official site, the Google Business Profile, directories, and citations, they gain confidence that all those references describe one entity, which strengthens resolution and local ranking. When the data conflicts – a different suite number here, an old phone number there, an abbreviated name elsewhere – the systems hedge, the entity can fragment into partial duplicates, and local recognition weakens. The fix is governance: establishing the canonical NAP, then auditing and correcting it everywhere it appears, including the long tail of directories that accumulate stale data. For multi-location businesses this is ongoing work, since listings drift. We track how NAP consistency translates into local search and entity recognition with IMPACT™.
