Frequently Asked Questions
Is the NAP Consistency Checker really free?
Yes — unlimited use, no signup, no credit card. We built these tools to help you audit sites without paying for a data subscription.
What is NAP consistency?
NAP stands for Name, Address and Phone number. NAP consistency means your business details are written the same way on your website, your Google Business Profile and every directory or citation that lists you.
Why does NAP consistency matter for local SEO?
Search engines compare your details across many sources to confirm your business is real and where it is located. Conflicting addresses or phone numbers can confuse customers and weaken the trust signals behind local rankings.
How does this NAP checker work?
Paste your business name, address and phone number as they appear on two listings. The tool compares the two sets field by field and highlights differences such as abbreviations, missing suite numbers or different phone formats.
Does the tool save the details I paste?
No. The details you paste are only used to run the comparison and are not saved.
What should I do when the checker finds a mismatch?
Choose one correct format, update your Google Business Profile first, then your website footer, contact page and LocalBusiness schema, and then each directory listing. Re-check each listing after you edit it.
NAP stands for Name, Address, and Phone — the core business details that appear across your website, Google Business Profile, and dozens of directories and citations. Search engines use consistency of this information as a local-ranking and trust signal. Even small differences ("St" vs "Street," different phone formats) can dilute that signal. This tool compares your NAP across two listings to catch inconsistencies.
How to Use This Tool
Paste your business name, address, and phone exactly as they appear on two different places (for example, your website footer and your Google Business Profile), then click Compare NAP.
What This Tool Checks
It compares the two sets of details you paste and flags any field that differs. It normalizes for punctuation and spacing so it catches meaningful differences rather than trivial formatting.
Understanding Your Results
A "differs" flag means the two listings don't match on that field — worth standardizing. Consistent NAP across all your listings reinforces to search engines that they're all about the same real business.
SEO Best Practices
Pick one canonical format for your business name, address, and phone, and use it identically everywhere. Audit your major citations periodically, since directories sometimes alter or auto-format your details.
Example
Comparing your website ("123 Main St, Suite 200") against a directory listing ("123 Main Street") flags the address as differing — a small but worth-fixing inconsistency.
Common Mistakes to Avoid
Don't use different phone numbers (like a tracking number) on different listings without realizing it fragments your NAP signal. Don't ignore minor-looking differences — consistency is the whole point.
