Definition block NAP consistency means ensuring your business Name, Address, and Phone number are identical across every online listing, directory, and citation. Even small variations, like 'St' vs 'Street', can cause problems.

Expanded explanation

## Why NAP Consistency Matters for SEO

Inconsistent NAP data confuses search engines and erodes trust in your business information. Google cross-references your NAP across the web to validate your business exists where you say it does. Discrepancies create doubt, and doubt kills local rankings.

## How NAP Consistency Works

Search engines crawl directories, social profiles, data aggregators, and your website to build a picture of your business. When your NAP matches everywhere, it reinforces confidence. When it does not, Google may display incorrect information or rank you lower because it cannot verify your details.

## Common Mistakes

- Using different phone numbers or address formats across listings
- Forgetting to update old listings after a business move or rebrand
- Not auditing NAP consistency across data aggregators and lesser-known directories
