SQMViews is a simple and lightweight tracking and analytics plugin that helps you understand how visitors interact with your WordPress content—without sending data to third-party services. 
Plugin adds very little overhead, capable of tracking millions of page views per day on a moderately sized website. 
Plugin includes sqm-views-pages.php drop-in script installation (Fast endpoint) to collect pageviews without loading WordPress core, reducing pageview request from 250 ms to 5 ms. If drop-in installation is not possible, the plugin falls back to the WordPress call (API endpoint).
<h4>Key Features</h4>
Tracking & Analytics:
<ul>
<li>Near real-time page view tracking</li>
<li>Engagement metrics (time on page, active time)</li>
<li>Shows user activity (clicks, scrolls, etc.) with privacy-friendly event counting</li>
<li>Interactive analytics dashboard with D3.js visualizations</li>
<li>Historical data with daily aggregation</li>
<li>Filter by date range, content type, and more</li>
</ul>
Performance:
<ul>
<li>Ultra-fast tracking endpoint (bypasses a core load)</li>
<li>Minimal overhead (~5ms per request with the drop-in script)</li>
<li>File-based batch processing (no database requests during the pageview event collection, only during cron processing)</li>
<li>Efficient data storage with automatic archiving</li>
<li>Configurable background processing via WP-Cron</li>
</ul>
Drop-in script 
* Created to minimize overhead 
* Uses exactly the same code as the API endpoint except two hooks for config modification (sqm_views_ping_interval, sqm_views_session_timeout) 
* Run strict JSON request schema validation to minimize attack surface. 
* Receives request, run validation, add it to a file for the later batch processing. Very low memory and CPU footprint.
Pageview lifetime 
JS code will send an <code>init</code> event, followed by <code>ping</code> events and completed by <code>exit</code> or <code>timeout</code> events. Unique ID is returned during <code>init</code> used for all the following events. During cron processing all the events with the same IDs are combined into a single pageview and stored in the database.
Privacy & Control:
<ul>
<li>100% privacy-focused (no external services)</li>
<li>All data stays on your server</li>
<li>Encrypted tracking payloads (you don’t need to reveal everything you track)</li>
<li>Full control over what gets tracked</li>
<li>GDPR-friendly (no personal data collected by default), we focus on pageviews</li>
</ul>
Flexibility:
<ul>
<li>Track custom post types and taxonomies</li>
<li>30+ developer hooks for customization</li>
<li>WP-CLI commands for automation</li>
<li>Translation-ready (i18n)</li>
<li>REST API for integrations</li>
</ul>

Examples 
Frontend Hooks – Control Tracking Behavior:
Exclude logged-in administrators from tracking (will not work properly if you cache pages or use CDN):
<pre><code>add_filter( 'sqm_views_should_track', function( $should_track, $data ) {
 if ( current_user_can( 'manage_options' ) ) {
 return false;
 }
 return $should_track;
}, 10, 2 );
</code></pre>
Modify tracking data before sending:
<pre><code>add_filter( 'sqm_views_tracking_data', function( $data ) {
 // Add custom metadata
 $data['custom_field'] = get_post_meta( get_the_ID(), 'my_field', true );
 return $data;
} );
</code></pre>
Customize which post types are tracked (overrides UI settings):
<pre><code>add_filter( 'sqm_views_tracked_post_types', function( $post_types ) {
 // Add custom post type
 $post_types[] = 'portfolio';
 return $post_types;
} );
</code></pre>
Processing Hooks – Modify Data Before Storage:
Calculate custom engagement metrics:
<pre><code>add_filter( 'sqm_views_calculated_metrics', function( $metrics, $records ) {
 // Calculate engagement score
 $metrics['engagement_score'] = ( $metrics['active'] / max( 1, $metrics['on_page'] ) ) * 100;

 // Calculate bounce rate indicator
 $metrics['likely_bounce'] = $metrics['on_page'] < 5 ? 1 : 0;

 return $metrics;
}, 10, 2 );
</code></pre>
Filter records before processing:
<pre><code>add_filter( 'sqm_views_before_process_record', function( $record ) {
 // Exclude specific URLs
 if ( strpos( $record['url'], '/test-page/' ) !== false ) {
 return null; // Skip this record
 }
 return $record;
} );
</code></pre>
REST API Hooks – Customize Chart Data:
Modify chart permissions:
<pre><code>add_filter( 'sqm_views_rest_permissions', function( $has_permission ) {
 // Allow editors to view analytics
 return current_user_can( 'edit_posts' );
} );
</code></pre>
Activation Hooks – Adjust Default Settings:
Set custom default settings on activation:
<pre><code>add_action( 'sqm_views_activated', function() {
 // Set default processing interval
 update_option( 'sqm_views_cron_interval', 'hourly' );

 // Enable external JavaScript by default
 update_option( 'sqm_views_js_mode', 'external' );
} );
</code></pre>
Cron Hooks – Custom Processing Schedules:
Run custom tasks after processing:
<pre><code>add_action( 'sqm_views_after_process', function( $processed_count ) {
 // Send notification if processing high volume
 if ( $processed_count > 10000 ) {
 wp_mail(
 get_option( 'admin_email' ),
 'SQMViews High Volume Alert',
 sprintf( 'Processed %d records', $processed_count )
 );
 }
}, 10, 1 );
</code></pre>
REST API: 
* <code>POST /wp-json/sqm-views/v1/track</code> – Submit tracking data through WordPress API endpoint 
* <code>POST sqm-views-pages.php</code> – Submit tracking data through Fast endpoint 
* <code>GET /wp-json/sqm-views/v1/charts</code> – Retrieve chart data
WP-CLI: 
* <code>wp sqm-views process</code> – Process pending statistics
