How to Develop a WordPress Conversion Analytics Plugin

Step 1: Define the Plugin’s Features

Before writing code, list the core functionalities your plugin should include:

✅ Track form submissions and button clicks
✅ Measure eCommerce sales conversions
✅ Provide a dashboard for real-time analytics
✅ Log user behavior (scroll depth, time on page, etc.)
✅ Ensure lightweight and fast performance

Step 2: Set Up the Plugin Structure

Create a new directory in wp-content/plugins/:

wp-conversion-analytics/
│── wp-conversion-analytics.php
│── includes/
│── assets/
│── templates/
│── admin/

• wp-conversion-analytics.php – The main plugin file
• includes/ – Core tracking functions
• assets/ – JavaScript and CSS for tracking
• templates/ – Dashboard UI components
• admin/ – Plugin settings and reports

Step 3: Register the Plugin in WordPress

Inside wp-conversion-analytics.php, define the plugin metadata:

<?php
/*
Plugin Name: WP Conversion Analytics
Plugin URI: https://yourwebsite.com
Description: A WordPress plugin to track and analyze conversions.
Version: 1.0
Author: Your Name
Author URI: https://yourwebsite.com
License: GPL2
*/

Step 4: Create a Database Table to Store Conversion Data

Store tracked conversions in a custom table.

global $wpdb;
$table_name = $wpdb->prefix . 'conversion_logs';

$sql = "CREATE TABLE $table_name (
    id BIGINT(20) NOT NULL AUTO_INCREMENT,
    event_type VARCHAR(100) NOT NULL,
    event_value TEXT NOT NULL,
    page_url TEXT NOT NULL,
    user_ip VARCHAR(45),
    event_time DATETIME DEFAULT CURRENT_TIMESTAMP,
    PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;";

require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
dbDelta($sql);

Step 5: Track Conversions with JavaScript and PHP

Use JavaScript to capture clicks and form submissions.

document.addEventListener("DOMContentLoaded", function() {
    document.querySelectorAll(".conversion-button").forEach(button => {
        button.addEventListener("click", function() {
            fetch(wp_conversion_ajax.ajax_url, {
                method: "POST",
                headers: { "Content-Type": "application/x-www-form-urlencoded" },
                body: "action=log_conversion&event_type=button_click&event_value=" + this.innerText
            });
        });
    });
});

Use PHP to store conversion data:

function log_conversion() {
    global $wpdb;
    $table_name = $wpdb->prefix . 'conversion_logs';

    $event_type = sanitize_text_field($_POST['event_type']);
    $event_value = sanitize_text_field($_POST['event_value']);
    $page_url = $_SERVER['HTTP_REFERER'];
    $user_ip = $_SERVER['REMOTE_ADDR'];

    $wpdb->insert($table_name, array(
        'event_type' => $event_type,
        'event_value' => $event_value,
        'page_url' => $page_url,
        'user_ip' => $user_ip,
    ));

    wp_die();
}
add_action('wp_ajax_log_conversion', 'log_conversion');
add_action('wp_ajax_nopriv_log_conversion', 'log_conversion');

Step 6: Create an Admin Dashboard for Reporting

Add a menu item for analytics reports.

function conversion_analytics_admin_menu() {
    add_menu_page(
        'Conversion Analytics',
        'Conversion Analytics',
        'manage_options',
        'conversion-analytics',
        'conversion_analytics_dashboard',
        'dashicons-chart-pie'
    );
}
add_action('admin_menu', 'conversion_analytics_admin_menu');

function conversion_analytics_dashboard() {
    global $wpdb;
    $table_name = $wpdb->prefix . 'conversion_logs';

    $results = $wpdb->get_results("SELECT event_type, COUNT(*) as count FROM $table_name GROUP BY event_type");

    echo "<h1>Conversion Analytics Dashboard</h1>";
    foreach ($results as $row) {
        echo "<p><strong>{$row->event_type}:</strong> {$row->count} conversions</p>";
    }
}

Step 7: Optimize Performance & GDPR Compliance

✅ Store only essential user data
✅ Provide an opt-out option
✅ Use AJAX-based tracking for faster performance
