Introduction
Building a WordPress multi-step lead capture plugin with Google Sheets integration is one of the most powerful ways to generate high-quality leads directly from your blog posts. If you're using Bricks Builder and want a premium SaaS-style widget that captures user details (Name → Email → Phone), stores them in Google Sheets as primary storage, and keeps a backup inside WordPress — this complete guide will walk you through everything step-by-step.
In this tutorial, we’ll cover:
Creating a custom lightweight WordPress plugin
Connecting WordPress to Google Sheets via Apps Script webhook
Multi-step lead capture form with partial saving
Sticky mobile version (30% scroll trigger)
Exit intent popup (mouse exit + 40s inactivity)
Admin lead dashboard inside WordPress
Performance optimization with WP Rocket & Cloudflare
Security hardening
Premium SaaS UI styling
Why Build a Custom Lead Capture Plugin Instead of Using a Form Plugin?
Limitations of Typical Form Plugins
Most plugins:
Store leads only in WordPress DB
Don’t support partial lead saving
Don’t offer Google Sheets as primary storage
Load heavy scripts (affects PageSpeed)
Don’t support advanced UI triggers (exit intent + scroll-based sticky)
If you're serious about conversions, you need more control.
Final Architecture Overview (Enterprise Safe Setup)
We decided on this structure:
Storage Layer
✅ Google Sheets → Primary storage
✅ WordPress Database → Backup storage
✅ Partial lead saving at every step
✅ Session tracking
✅ Page URL tracking
✅ Auto serial numbering
✅ Submission date
Step 1: Creating the Google Sheets Webhook (Primary Storage)
Create Google Sheet
Create a sheet with these headers:
| Serial No | Full Name | Email | Phone | Page URL | Step | Date |
Create Google Apps Script Webhook
Go to: https://script.google.com
Create new project
Paste webhook script
Deploy as Web App
Set:
Execute as: Me
Access: Anyone
Copy Web App URL
This becomes your webhook endpoint.
Step 2: WordPress Plugin Architecture
Instead of using shortcodes or code snippets, we built a modular plugin:
ip-lead-engine/
│
├── ip-lead-engine.php
├── includes/
│ ├── rest-api.php
│ ├── admin-dashboard.php
│ ├── security.php
│
├── assets/
│ ├── css/
│ ├── js/
│ └── images/
│
└── templates/
├── inline.php
├── sticky.php
└── popup.php
Step 3: Multi-Step Lead Capture Flow
Step Flow
1️⃣ Step 1 → Full Name
2️⃣ Step 2 → Email
3️⃣ Step 3 → Phone
Each step:
Saves partial data
Sends to Google Sheets
Saves backup in WordPress DB
Associates session ID
Step 4: Frontend Versions Implemented
- Inline Bricks Component
No shortcode
Native container compatible
Add via DIV with ID
Can appear 2–3 times per blog post
- Sticky Mobile Version (30% Scroll Trigger)
Activates after 30% scroll
Slides up smoothly
Multi-step flow
No CLS impact
- Exit Intent Popup
Triggers:
Mouse exit (desktop)
40 seconds inactivity (all devices)
Runs once per session (non-intrusive).
Step 5: Premium SaaS Design Features
Static round avatar image (default placeholder)
Gradient animated CTA
Micro-interactions
Smooth transitions
Responsive layout
Clean typography
Lightweight vanilla JS (no jQuery)
Step 6: WordPress Admin Dashboard
Inside WP Admin → Lead Engine:
Features:
Total leads count
Partial leads count
Conversion %
Last 10 leads table
Google webhook status
Feature toggles:
Inline ON/OFF
Sticky ON/OFF
Popup ON/OFF
Avatar upload option
CTA text editor
Export CSV
View backup DB leads
Step 7: Security Hardening
Implemented protections:
REST API nonce verification
Input sanitization
Honeypot anti-bot
Rate limiting
Session validation
CSRF protection
Cloudflare compatible
Step 8: Performance Optimization (Google PageSpeed Safe)
Since we’re using:
Bricks Builder 2.2
WP Rocket
Cloudflare
We ensured:
Scripts load only on single posts
No jQuery dependency
No heavy libraries
Lazy popup initialization
Under ~25KB total assets
No render blocking
No layout shift
Asynchronous fetch
Result:
No negative Google PageSpeed impact.
