How to Find Leads by Google Review Rating

Find B2B leads by filtering Google review ratings and review counts. Target businesses with low ratings for service pitches or high ratings for partnerships.

Google review ratings are a powerful lead qualification signal. Businesses with low ratings often need help with reputation management, customer service, or product quality. Businesses with high ratings and many reviews are strong partnership candidates. This tutorial shows how to use the Scavio API to search for local businesses, filter them by rating and review count, and build a qualified lead list. You will create a pipeline that targets businesses in specific rating ranges and exports them for outreach.

Prerequisites

  • Python 3.8+ installed
  • requests library installed
  • A Scavio API key from scavio.dev
  • A target industry and location

Walkthrough

Step 1: Search for businesses by category

Query Google Maps for businesses in your target category and location.

Python
import os, requests, json

API_KEY = os.environ["SCAVIO_API_KEY"]

def search_businesses(category, location):
    resp = requests.post("https://api.scavio.dev/api/v1/search",
        headers={"x-api-key": API_KEY},
        json={"platform": "google", "query": f"{category} in {location}", "type": "maps"})
    return resp.json().get("local_results", [])

businesses = search_businesses("dentists", "San Francisco")
print(f"Found {len(businesses)} businesses")

Step 2: Filter by rating range

Segment businesses into lead categories based on their review ratings.

Python
def filter_by_rating(businesses, min_r, max_r, min_reviews=5):
    return [
        b for b in businesses
        if min_r <= float(b.get("rating", 0)) <= max_r
        and int(b.get("reviews", 0)) >= min_reviews
    ]

low_rated = filter_by_rating(businesses, 1.0, 3.5)
high_rated = filter_by_rating(businesses, 4.5, 5.0, min_reviews=50)
print(f"Low rated leads: {len(low_rated)}")
print(f"High rated prospects: {len(high_rated)}")

Step 3: Enrich leads with additional data

Search for each lead's website to find contact information and context.

Python
def enrich_lead(business):
    name = business.get("title", "")
    resp = requests.post("https://api.scavio.dev/api/v1/search",
        headers={"x-api-key": API_KEY},
        json={"platform": "google", "query": f"{name} contact"})
    results = resp.json().get("organic_results", [])[:2]
    return {
        "name": name,
        "rating": business.get("rating", ""),
        "reviews": business.get("reviews", 0),
        "address": business.get("address", ""),
        "phone": business.get("phone", ""),
        "website": results[0].get("link", "") if results else "",
    }

Step 4: Export qualified leads

Save the filtered and enriched leads to a JSON file for your CRM or outreach tool.

Python
import csv

def export_leads(leads, filename):
    enriched = [enrich_lead(b) for b in leads]
    with open(filename, "w", newline="") as f:
        w = csv.DictWriter(f, fieldnames=enriched[0].keys())
        w.writeheader()
        w.writerows(enriched)
    print(f"Exported {len(enriched)} leads to {filename}")

export_leads(low_rated[:10], "low_rated_leads.csv")

Python Example

Python
import os, requests
API_KEY = os.environ["SCAVIO_API_KEY"]
resp = requests.post("https://api.scavio.dev/api/v1/search",
    headers={"x-api-key": API_KEY},
    json={"platform": "google", "query": "dentists in San Francisco", "type": "maps"})
for b in resp.json().get("local_results", []):
    r = float(b.get("rating", 0))
    if r <= 3.5 and int(b.get("reviews", 0)) >= 5:
        print(f"{b['title']} - {r} stars ({b.get('reviews')} reviews)")

JavaScript Example

JavaScript
const H = {"x-api-key": process.env.SCAVIO_API_KEY, "Content-Type": "application/json"};
const r = await fetch("https://api.scavio.dev/api/v1/search", {
  method: "POST", headers: H,
  body: JSON.stringify({platform: "google", query: "dentists in San Francisco", type: "maps"})
});
const data = await r.json();
(data.local_results || []).filter(b => parseFloat(b.rating||0) <= 3.5)
  .forEach(b => console.log(b.title, b.rating, b.reviews));

Expected Output

JSON
A qualified lead list of businesses filtered by Google review rating, enriched with contact data, and exported as CSV for outreach campaigns.
