NAP Consistency Checker
Audit your local business citations across web directories against your primary Master NAP. Uncover exact inconsistencies in business names, suite numbers, state abbreviations, phone formats, and website URLs that harm local map rankings.
About NAP Consistency Checker
The NAP Consistency Checker by URLSigma helps local SEO professionals, agencies, marketers, and business owners verify that their Name, Address, and Phone Number (NAP) remain consistent across online business directories and citations. By comparing multiple listings against a master business record, the tool identifies inconsistencies, calculates an overall consistency score, and provides practical recommendations for correcting citation errors.
Accurate business information is one of the foundations of successful local SEO. Even small differences between listings can reduce trust signals for search engines and create confusion for potential customers. This tool simplifies citation auditing by automatically detecting discrepancies and highlighting exactly what needs to be corrected.
