Why platform choice matters as much as review count
A restaurant with 400 reviews on TripAdvisor and 20 on Google is in a weaker position than a competitor with 150 reviews on Google and 30 on TripAdvisor — for the local market, at least. The asymmetry comes from how Google weights its own platform's signals in local search, and from how consumer search behavior aligns with specific platforms for specific needs.
Understanding this asymmetry is the basis of an intelligent routing strategy. Routing all review requests to a single platform regardless of trade type means leaving trust signals on the table in the places where your specific buyers actually look.
The universal rule: Google first
For nearly every service trade, Google reviews carry the most leverage on a single variable: local pack visibility. Because Google controls the search interface and the review platform simultaneously, reviews on Google have a direct line to the prominence score that determines local pack rankings.
This means that for any business where local search visibility drives customer acquisition — which describes virtually every service trade — Google reviews must be the primary routing destination. The question is not whether to prioritize Google, but how much secondary routing to the other platforms that matter for your specific trade.
Trade-by-trade platform priorities
HVAC, Plumbing, Electrical, Roofing
Google carries the most weight for both algorithmic rankings and consumer trust in these trades. HomeAdvisor and Thumbtack are relevant secondary platforms because they are purpose-built for service matching and consumers in high-urgency situations (a failed furnace in January) often search both Google and these platforms simultaneously.
Yelp has negligible influence in most home-service trade markets outside major coastal cities. Facebook reviews are worth maintaining because they surface in branded searches, but they should not receive primary routing traffic.
Restaurants and Food Service
Google and Yelp are both meaningfully influential in this category. Google dominates proximity-based searches ("restaurants near me"), while Yelp maintains a strong user base among consumers who explicitly seek community-sourced opinions and browse rather than search. TripAdvisor matters in tourist-heavy markets and for dinner-category restaurants. For casual and fast-casual formats, Google first is still the right priority.
Salons, Spas, and Personal Care
Google and Yelp both matter. Yelp has maintained stronger relative authority in personal services than in home trades, partly because its user base skews toward the demographics that dominate personal care decision-making. Google Maps is increasingly the primary search interface for this category as well. A routing split weighted toward Google with Yelp as consistent secondary is appropriate.
Healthcare — Dentists, Chiropractors, Therapists, Primary Care
Google matters for proximity searches. Healthgrades is the dominant platform for healthcare-specific queries and often outranks Google Business Profiles for queries like "best dentist [city]." Zocdoc matters in markets where online scheduling is normalized. Practices that ignore Healthgrades and focus exclusively on Google are missing a meaningful share of their category's search traffic.
Legal Services
Avvo dominates attorney-specific searches and its profiles rank highly for "lawyer near me" queries in most markets. Google matters for branded and proximity searches. Facebook reviews are relevant for consumer-facing practices (family law, estate planning) where community trust signals carry weight. A routing strategy that excludes Avvo for legal practices is leaving significant category-specific visibility on the table.
Remodeling, Landscaping, Interior Design
Google first, then Houzz. Houzz has built strong category authority for home improvement and design, and its review content appears prominently in searches for high-involvement projects. Unlike HVAC where urgency drives instant decisions, remodeling involves extended research periods where Houzz is often part of the consideration journey.
Auto Repair and Detailing
Google is dominant. CarFax's service history database has some consumer mindshare for repair shops, but reviews that drive actual job decisions come primarily from Google and occasionally Yelp in urban markets. Platforms like RepairPal have niche audiences but represent secondary routing at best.
The platforms not worth primary routing
Several platforms accumulate reviews without contributing meaningfully to either local search rankings or consumer acquisition:
Angi (formerly Angie's List): Reviews collected on Angi do not transfer to Google Business Profile and have limited search visibility outside the Angi ecosystem. For businesses that also buy leads through Angi, maintaining a profile makes sense — but routing organic review requests there diverts traffic from platforms with broader reach.
BBB (Better Business Bureau): BBB profiles appear in branded searches and can matter for reputation management during complaints, but BBB reviews do not contribute to local search rankings and consumer acquisition in the way Google reviews do. Maintaining a BBB profile is worthwhile; routing review requests there is not.
Trustpilot: Primarily B2B and e-commerce oriented. Minimal relevance for local service businesses.
Building a routing hierarchy
The practical output of platform analysis is a routing hierarchy: a ranked list of destination platforms, ordered by their leverage on your specific business outcomes.
For most service businesses, the hierarchy looks like:
- Google (primary — local search visibility + consumer trust)
- Trade-specific platform (Healthgrades, Avvo, Houzz, etc. — category authority)
- Yelp (relevant in personal services, restaurants, some urban home service markets)
- Facebook (community trust signal, branded search coverage)
A well-configured routing system sends new review requests to platform 1 as the default, rotates to platform 2 for accounts that already have strong Google profiles, and occasionally pushes traffic to platforms 3 and 4 for breadth. The goal is not an even distribution — it is maximum leverage on the platforms that drive the most decisions for your trade.
