NAP and Citation Auditing
Session 10.6 · ~5 min read
NAP consistency was the first thing you built in Module 1. It is also the first thing that breaks. Business directories get overwritten by data aggregators. Staff members update one listing but not others. You move offices, change phone numbers, or rebrand. Every one of these events creates an inconsistency. And inconsistencies, once created, do not fix themselves.
Citation auditing is the ongoing practice of verifying that your Name, Address, and Phone number are identical across every platform where they appear. It is not glamorous work. But it is the foundation that everything else sits on. If your NAP is inconsistent, every other entity signal you send is undermined by contradictory information.
How Inconsistencies Happen
Understanding the sources of inconsistency helps you prevent them. The most common causes are not mistakes you make directly. They are systemic.

Data aggregators are the primary culprit. Companies like Foursquare (formerly Factual), Neustar Localeze, and Data Axle collect business information and distribute it to hundreds of directories, apps, and platforms. If the aggregator has your old information, it will continuously push that old data to directories, overwriting any manual corrections you have made.
This is why updating individual directories is necessary but insufficient. You must also update the aggregators themselves, or the problem will recur.
Audit Frequency by Platform Type
Not all platforms need the same attention. High-traffic, high-authority platforms deserve more frequent checks because errors there cause more damage. Low-traffic directories can be checked less often.
| Platform Type | Examples | Audit Frequency | Priority | Why |
|---|---|---|---|---|
| Google properties | GBP, Google Maps | Weekly | Critical | Primary entity signal source |
| Major search engines | Bing Places, Apple Maps | Monthly | High | Cross-engine entity validation |
| Social platforms | Facebook, LinkedIn, Instagram | Monthly | High | sameAs targets, high visibility |
| Review platforms | Yelp, TripAdvisor, Trustpilot | Monthly | High | Consumer-facing, feed into KP |
| Industry directories | Chamber of Commerce, trade associations | Quarterly | Medium | Authority citations, niche relevance |
| Data aggregators | Foursquare, Neustar Localeze, Data Axle | Quarterly | High | Feed hundreds of downstream directories |
| General directories | Yellow Pages, Superpages, Hotfrog | Quarterly | Low | Low traffic, but contribute to citation volume |
| Your own website | Homepage, contact page, footer | Monthly | Critical | Canonical source of truth |
The Audit Process
A citation audit follows a specific sequence. Doing it out of order wastes time because you might fix a directory only to have an aggregator overwrite your fix a week later.
- Establish the canonical NAP. Decide on your single, official Name, Address, and Phone. Write it down exactly as it should appear everywhere. This is your source of truth.
- Audit your own website first. Your homepage, contact page, footer, and structured data must all show the canonical NAP. Fix any discrepancies here before touching anything external.
- Audit data aggregators. Submit your canonical NAP to each aggregator. This prevents downstream re-contamination.
- Audit high-priority platforms. Check GBP, Bing, Apple Maps, social profiles, and review sites. Correct any discrepancies.
- Audit remaining directories. Work through lower-priority directories. Use a tool like BrightLocal or Moz Local to scan for listings you may not even know about.
- Document everything. Record the date of each audit, what was found, and what was corrected. This log is essential for tracking progress and identifying recurring issues.
Common NAP Variations That Cause Problems
These are not obvious errors. They are subtle differences that humans ignore but machines treat as conflicting data.
| Variation Type | Example A | Example B | Impact |
|---|---|---|---|
| Abbreviation | 123 Main Street | 123 Main St. | Moderate: may be treated as different address |
| Suite / unit | 123 Main St, Suite 200 | 123 Main St | Moderate: missing suite number |
| Phone format | (555) 123-4567 | 555-123-4567 | Low: usually normalized, but not always |
| Business name suffix | Acme Corp | Acme Corporation | High: may be treated as different entity |
| Legal entity indicator | Acme Corp | Acme Corp, LLC | High: different name string |
| Tracking phone number | Main line: 555-123-4567 | Tracking: 555-987-6543 | High: two different phone numbers for one entity |
NAP auditing is not a project with an end date. It is a maintenance practice with a rhythm. The businesses that stay consistent are the ones that check consistently.

Assignment
Conduct a NAP consistency audit for your entity.
- Write your canonical NAP: the exact Name, Address, and Phone number as they should appear everywhere.
- Check your own website (homepage, contact page, footer, structured data). Does every instance match the canonical NAP exactly? Note any variations.
- Check your Google Business Profile, Bing Places, and Apple Maps listings. Record the NAP shown on each.
- Check three social profiles (LinkedIn, Facebook, and one other). Record the NAP or business info shown.
- Check two industry-specific directories relevant to your business. Record what they show.
- Create a summary table listing each platform, the NAP it displays, and whether it matches your canonical version. Flag any mismatches for correction.
