Local Lead Enrichment Engine – Agency‑Grade Local Lead Scoring API

The Local Lead Enrichment Engine is a compound Apify Actor designed to build high-quality, enriched local business lead lists. While traditional Maps/Yelp scrapers only extract basic address and contact information, this Actor performs multi-stage domain and social intelligence checks to qualify and score leads automatically.

🌟 What Problem It Solves

Most B2B outreach campaigns fail because the lead lists are cold and unqualified. A list of 1,000 businesses scraped from Google Maps might contain invalid websites, dead domains, or businesses with no reviews.

The Local Lead Enrichment Engine enriches these raw lists in real-time, computing:

• Online Presence Score (0–100): Strength of their website and social media footprint.
• Review Health Score (0–100): Rating distribution and platform diversity.
• Lead Quality Score (0–100): A deterministic, B2B-tailored quality index based on tech-stack modernness, domain age, and review health.

This allows agencies, sales teams, and marketers to target only the high-value prospects and tailor their pitch based on the prospect's actual tech stack and online visibility gaps.

⚙️ How It Works (The 3-Stage Pipeline)

graph TD
    A[Input: Location & Keywords] --> B[Stage 1: Google Maps / Local Directories Scraper]
    B --> C[Local Candidate Businesses]
    C --> D[Stage 2: Domain Intelligence WHOIS, DNS, Tech Stack]
    D --> E[Stage 3: Review & Social Media Presence Checks]
    E --> F[Scoring Engine: Compute Quality Indexes]
    F --> G[(Dataset Output / Standby HTTP Response)]

Stage 1: Local Candidate Collection

Queries Google Maps or other local directories using search query strings combined from your locationQuery and industryKeywords. It compiles names, addresses, ratings, and website URLs.

Stage 2: Domain Intelligence (B2B Signals)

Extracts the base domain from the business website and performs WHOIS/DNS lookups to find:

• Domain registration dates and registrar details.
• Tech stack profile (WordPress, Shopify, Webflow, Google Analytics, Stripe, HubSpot, etc.).
• DNS record validation (MX, TXT).

Stage 3: Review & Social Presence Checks

Searches review platforms (Google, Yelp, Facebook) and social networks (LinkedIn, Facebook, Instagram, Twitter) to find contact emails, platform counts, and social profiles.

🚀 Execution Modes

1. Batch Job Mode (Standard Run)

Perfect for building large bulk lists. Configure your inputs in the Apify Console and run. It outputs results to two datasets:

• default (enriched_businesses): One outreach-ready row per business.
• diagnostics: A per-business, per-stage log showing which lookups succeeded, skipped, or errored.

2. Standby Mode (Realtime HTTP API)

Enables a persistent HTTP server within the Actor to eliminate container start-up latency. You can call the /enrich-local-leads endpoint in real-time:

• Endpoint: POST /enrich-local-leads
• Port: Controlled by ACTOR_WEB_SERVER_PORT (typically proxied by Apify Console)
• Response: Returns JSON containing enrichedBusinesses and diagnostics directly in the HTTP body.

💡 Best Practices

1. Scraping Volume & Limits: Keep maxBusinesses under 200 per search to avoid long-running crawls. This Actor focuses on enrichment quality over scraping raw numbers.
2. Proxy Settings: Always keep useApifyProxy enabled. Domain enrichment and Maps scraping perform a large number of requests that will get blocked without residential proxies.
3. Standby Mode Usage: For real-time applications (like website forms or CRM integrations), keep the Actor in Standby Mode. The /enrich-local-leads endpoint will reply within seconds using simulated caches when API scrapers take too long.
4. Legal Compliance: Comply with the target sites' terms of service, robots.txt guidelines, and local regulations (such as GDPR or CAN-SPAM) before initiating cold outreach campaigns using the phone or email addresses fetched.
