Definition
Review-based lead qualification is the practice of using Google review ratings and review counts extracted via SERP API to score and prioritize B2B leads, targeting businesses with low ratings (pain signal) or high volume (established business).
In Depth
Google review data is publicly visible but manually checking reviews for hundreds of prospects is impractical. Automated review extraction via SERP API enables a qualification layer: search each prospect's business name, extract their Google rating and review count from the Maps Pack or knowledge panel, and use these as scoring signals. Scavio ($0.005/query, free 250/mo) returns review data as part of Google search results. Outscraper (free 500 records, $3/1K) provides deeper review extraction including individual review text. Qualification patterns: (1) Low rating (<3.5 stars) + high review count (>50 reviews) = established business with service quality issues -- ideal prospect for service improvement tools. (2) High rating (>4.5) + low review count (<10) = new business that needs growth -- ideal for marketing services. (3) No Google presence = either too small or B2B-only -- may not be a fit for local-focused offerings. Cost for qualifying 500 leads: $2.50 (500 queries x $0.005) via Scavio. The review score adds a data point that contact databases like Apollo or ZoomInfo do not provide, enabling more targeted outreach sequences based on actual business performance rather than just firmographic data.
Example Usage
A reputation management agency qualifies 1,000 local business leads per month. For each business, one Scavio search extracts the Google rating and review count. Leads with <3.5 stars and >30 reviews are flagged as high-priority (120 leads). The agency sends a one-page audit showing the business's rating vs competitors, achieving a 7.2% reply rate on these qualified leads vs 1.8% on unqualified cold lists. Monthly search cost: $5. Additional revenue from improved targeting: 4 extra clients/month at $500/mo retainer each.
