SEO: Local
Guides local SEO: Google Business Profile, NAP consistency, and citation building. Businesses with accurate NAP across 40+ authoritative sites see ~19% higher visibility in Google Maps. Use this skill when optimizing for local search, setting up GBP, or auditing citations.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read Sections 4 (Audience), 5 (Website).
Identify: 1. Business type: Storefront vs service-area 2. Location: Single or multiple 3. Current listings: Existing GBP, directories
NAP Consistency
NAP = Name, Address, Phone. Critical for local rankings.
| Rule | Guideline |
|---|---|
| Exact match | "Street" vs "St." or "LLC" inconsistency = Google may treat as different entities |
| Fix first | Audit and fix inconsistencies before adding new citations |
| Tools | BrightLocal, Whitespark, Moz Local for audit |
Google Business Profile
| Element | Guideline |
|---|---|
| Address | Physical address; no P.O. boxes |
| Description | 750 chars; primary keywords in first 100 |
| Hours | Accurate; seasonal availability |
| Category | Primary category matches business type |
| Service-area | Hide address if no storefront; define service areas |
Citation Building
Targeted precision over submitting to every directory.
Priority order: 1. Google Business Profile 2. Apple Maps 3. Yelp, Bing Places, Facebook 4. Better Business Bureau, Foursquare, Nextdoor 5. Niche directories (Healthgrades, Angi, etc.)
Citation Audit
- Incorrect or outdated data
- Duplicate entries
- Missing listings on key directories
Fix before adding; compounding errors harm rankings.
Output Format
- NAP (exact format for consistency)
- GBP optimization checklist
- Citation priority list
- Audit findings (if applicable)
