Key Concepts
What Is NAP Consistency?
NAP stands for Name, Address, and Phone Number. NAP consistency means that your business name, address and phone number appear in exactly the same format on every website, directory and platform where your business is listed. This includes your Google Business Profile, website, Facebook, Instagram, Twitter/X, LinkedIn, Yellow Pages, Yelp, TrueLocal, industry directories, and anywhere else your business appears online.
Why Google Cares About NAP
Google's algorithm analyses citation data from across the web to verify business information. When Google sees your business Name, Address and Phone number listed consistently across many reputable sources, it gains confidence that the information is accurate. This confidence translates to higher trust, which translates to higher local search rankings. When Google sees inconsistencies — different phone numbers, different address formats, different business name spellings — it becomes uncertain, and uncertainty leads to lower rankings.
Common NAP Inconsistency Sources
NAP inconsistencies most commonly occur when: a business moves to a new address but not all old listings are updated, a phone number changes and old numbers remain on some platforms, a business rebrands but old trading names remain on some directories, address formatting varies ("Street" vs "St", "Level 2" vs "Floor 2"), and multiple people manage different platforms without coordination.
Choosing a Master NAP Format
Decide on a single definitive format for your name, address and phone number — this becomes your "master NAP". Every other listing must match this exactly. Write it down and share it with anyone who manages your online presence. When creating new citations, copy and paste directly from your master NAP to prevent transcription errors.
Change Management
When your phone number, address or business name changes, create a prioritised update list of every platform that shows your information. Start with the most important (Google Business Profile, website, Facebook) and work systematically through all others. Track each update in a spreadsheet until all are complete. Do not delay — every day with inconsistent information is a day your rankings may be suppressed.
Step-by-Step Practice
Define your master NAP — write down the exact format for your business name, address and phone number.
Search Google for your business name and review the first 20 results for any inconsistencies.
Search Google for your old phone number or old address if applicable to find outdated listings.
Create a master spreadsheet listing every platform where your NAP appears and mark each as consistent or needs correction.
Systematically update any inconsistencies starting with the highest-authority platforms.
Ian's practical tip: I have defined my master NAP format and documented it. I have audited the top 20 online appearances of my business information. I have corrected all identified NAP inconsistencies. I have a change management process for future business information updates.
Practical Activity
Complete and record this task
After any business change — new address, new phone number, rebrand — spend at least 2 hours updating your NAP across all platforms before anything else. The longer inaccurate information exists online, the more it gets scraped and replicated across other directories, creating a much larger cleanup job later.
