The finding in one paragraph
Service-area businesses (plumbing, HVAC, electrical) compete for the moment a customer types an emergency search into Google or, increasingly, an AI assistant. We tested 5 standardized buyer questions a homeowner or facility manager might plausibly ask. Each question ran 3 times per engine across 4 engines. The result, per-engine breakdown, and per-prompt comparison are below.

What the full audit would fix for a service-area business brand
The head-to-head above measures citation share on a single shared prompt set. The paid SXO Audit produces specific, copy-paste-ready fix recommendations across the categories below. Counts are the approximate number of distinct fix recommendations the audit pipeline can produce per brand; the exact count varies by site.
| Fix category | Fix recommendations |
|---|---|
| Core fix categories (every audit) | |
| AI Search Visibility (LLM citations across 4 engines) | 8 |
| Schema Markup & JSON-LD (Organization, Product, FAQPage) | 6 |
| Buyer-Prompt-Matching FAQ + Content | 5 |
| Technical SEO Foundations (crawlability, render, canonicals) | 7 |
| Knowledge Graph & Entity Signals | 4 |
| Citation Footprints (third-party signals) | 5 |
| Core Web Vitals & Performance | 4 |
| Accessibility (WCAG 2.1 AA) | 5 |
| Core subtotal | ~44 |
| Additional service-area-specific fix categories | |
| Service-Area Business Configuration (GBP service areas, not pin) | 6 |
| AI Search for Emergency + Urgent Queries | 7 |
| Service Schema (Service, OfferCatalog, ServiceArea) | 5 |
| "Near Me" + Service-Specific Optimization | 6 |
| Phone + Booking Path Optimization | 4 |
| Trust Signals (Licensing, Certifications, BBB) | 5 |
| 24/7 Availability + Hours Schema | 4 |
| Service-Area Review Aggregation | 5 |
| Additional subtotal | ~42 |
| Total fix recommendations per brand | ~86 |
Every Web Cited audit includes the core fix categories above. A service-area business brand gets all of those PLUS the additional fix categories specific to service-area business businesses, because the channels and signals AI assistants consult for service-area business brands are different. The result is a meaningfully larger fix set for service-area business brands (~86 recommendations) than for online-only brands (~44 recommendations). The Playbook ships every fix as a copy-paste-ready remediation with the file, code, or content change spelled out.
