NAP consistency sounds dull because it is, right up until inconsistent details quietly tank your local visibility. Same name, same address, same number, everywhere. That is the whole game.
The short version
NAP consistency means keeping your business Name, Address, and Phone number identical across every place they appear online, from your website to directories and listings. Consistency builds trust with search engines and customers.
Why it matters
Conflicting details confuse search engines and erode trust. The basics still carry weight with customers too. BrightLocal research found that around 85 percent of consumers consider the presence of accurate contact information and opening hours important when researching a local business.

FAQ
Does a small difference in my address really matter?
It can. Inconsistencies like abbreviations or old phone numbers add up and can weaken trust signals. Aim for exact, identical details everywhere.
