AI-Powered Lead Scoring: +22% SQL-to-Close | -62.5% Unqualified Leads
Transforming Sales Pipeline Efficiency for a Multi-Vertical Digital Agency
The Problem: Low-Quality Leads Clogging the Sales Pipeline
A multi-vertical digital agency faced a critical challenge: despite strong paid media performance, their sales pipeline was overwhelmed by low-quality leads. This directly impacted sales team morale, increased operational friction, and severely suppressed SQL-to-Close rates.
Low Lead Quality
Form fills routed directly to CRM without prioritization or qualification
Sales Overwhelm
Reps spending excessive time on unqualified prospects
Suffering Conversion
SQL-to-Close rates significantly underperforming
Basic Filtering
No intelligent system for lead prioritization or enrichment
The Solution: Architecting an AI-Driven Lead Scoring Engine
I designed and implemented a sophisticated, multi-layered lead scoring system, integrating cutting-edge AI for enrichment and real-time behavioral insights. This solution transformed raw inputs into intelligently prioritized, sales-ready leads.
AI Enrichment (GPT)
Classifying and prioritizing leads based on form data to provide immediate context
Behavioral Scoring (Lift-AI)
Real-time assessment of on-site engagement patterns to gauge genuine interest
Orchestration (Make.com)
Seamlessly connecting all data points and routing logic for automated lead flow
Process Step 1: AI Enrichment & Classification with GPT
The process begins when a lead completes a web form. Instead of routing raw data directly to sales, we leverage AI to provide immediate context and qualification.
Form Trigger
Capture essential lead data (name, job title, company, email)
OpenAI GPT via Make.com
Form inputs sent to GPT for advanced classification and enrichment
Classification & Weighting
GPT intelligently classifies lead with custom scoring logic for job title, company size, and intent
Process Step 2: Real-time Behavioral Scoring with Lift-AI
Beyond declared intent, we integrated a real-time behavioral layer to understand true prospect engagement and interest levels.
Lift-AI Integration
Analyzes on-site session quality including scroll depth, pages viewed, time on site, and bounce indicators
Dynamic Scoring
Assigns a real-time score (0–100) based on engagement patterns and predictive algorithms
Data Storage
Scores are securely stored in session-level cookies or seamlessly piped via Segment for accessibility
GA4 Tracking
Tracks all relevant event performance for a holistic view of user behavior and funnel movement
Process Step 3: Composite Scoring & Strategic Routing
The true power lies in combining both AI-enriched data and real-time behavioral insights into a comprehensive lead score that dictates intelligent routing.
1
Weighted Composite Score
GPT output and Lift-AI scores are combined into a single, weighted composite score, providing a holistic view of lead quality
2
Threshold-Based Routing
Leads exceeding a predefined quality threshold are immediately routed to Sales for high-priority follow-up
3
Nurture Sequences
Below-threshold leads automatically enter tailored HubSpot nurture sequences, optimizing marketing's efforts
