## Kuvaus

**Core Web Vitals RUM** is a comprehensive WordPress plugin that monitors your website’s
Core Web Vitals metrics from real users, not just lab tests. Get actionable insights
to improve your site’s performance and SEO rankings.

#### Why Real User Monitoring (RUM)?

While tools like Google PageSpeed Insights provide valuable lab data, they don’t
reflect the actual experience of your visitors. Core Web Vitals RUM collects data
from real users across different devices, browsers, and network conditions, giving
you the most accurate picture of your site’s performance.

#### Key Features

🚀 **Real User Monitoring**
 * Collects LCP, INP, CLS, FCP, and TTFB from actual
visitors * Tracks performance across different devices and browsers * Provides accurate,
real-world performance data

📊 **Comprehensive Analytics**
 * Beautiful dashboard with real-time performance
scores * Detailed reports with trends and insights * Page-specific performance analysis*
Device and browser breakdown

🔔 **Smart Alerts**
 * Email notifications when performance drops * Configurable
thresholds for each metric * Daily, weekly, or immediate alerts * Beautiful HTML
email templates

📈 **Google Analytics 4 Integration**
 * Send Core Web Vitals data to GA4 * Custom
events for each metric * Enhanced GA4 reporting capabilities * Measurement Protocol
API integration

⚙️ **Flexible Configuration**
 * Adjustable sample rates (1-100%) * Customizable
performance thresholds * Data retention settings * Privacy-compliant data collection

🔒 **Privacy & Security**
 * GDPR-compliant data collection * IP address anonymization*
No personal data collection * Secure REST API endpoints with proper permission callbacks*
Input validation and sanitization on all data

#### Core Web Vitals Explained

**LCP (Largest Contentful Paint)**: Measures loading performance. Shows when the
largest content element becomes visible.

**INP (Interaction to Next Paint)**: Measures interactivity. Shows how quickly the
page responds to user interactions.

**CLS (Cumulative Layout Shift)**: Measures visual stability. Shows how much content
shifts during page load.

**FCP (First Contentful Paint)**: Measures loading performance. Shows when the first
content becomes visible.

**TTFB (Time to First Byte)**: Measures server response time. Shows how quickly 
the server responds to requests.

#### How It Works

 1. **Data Collection**: The plugin automatically collects Core Web Vitals data from
    your visitors
 2. **Analysis**: Data is processed and analyzed to provide meaningful insights
 3. **Reporting**: View comprehensive reports in your WordPress admin dashboard
 4. **Alerts**: Get notified when performance issues are detected
 5. **Integration**: Send data to Google Analytics 4 for enhanced reporting

#### Use Cases

 * **SEO Optimization**: Improve your Core Web Vitals scores for better search rankings
 * **Performance Monitoring**: Track performance trends over time
 * **Issue Detection**: Identify performance problems before they impact users
 * **Competitive Analysis**: Compare your performance against industry standards
 * **User Experience**: Ensure your site provides a great experience for all visitors

#### Privacy Compliance

The plugin is designed with privacy in mind:
 * No personal data is collected * 
IP addresses are anonymized * GDPR-compliant data collection * Users can opt-out
of data collection * Data is stored securely on your server

#### Data Collection & Third-Party Services

**What Data is Collected:**

This plugin collects anonymous performance metrics from your website visitors to
help you monitor and improve your site’s Core Web Vitals scores. The following data
is collected:

 * **Performance Metrics**: LCP (Largest Contentful Paint), INP (Interaction to 
   Next Paint), CLS (Cumulative Layout Shift), FCP (First Contentful Paint), and
   TTFB (Time to First Byte) values
 * **Page Information**: Page URL and page title where metrics were collected
 * **Technical Information**: Device type (mobile/tablet/desktop), connection type,
   user agent string
 * **Anonymized Location**: IP addresses are anonymized by removing the last octet(
   IPv4) or last 80 bits (IPv6)
 * **Session ID**: A randomly generated session identifier (not linked to any personal
   information)

**When Data is Collected:**

 * Data collection can be enabled or disabled at any time in the plugin settings
 * You can configure a sample rate (1-100%) to control what percentage of visitors
   have their metrics collected
 * Data is collected only when visitors load pages on your website
 * Collection is disabled by default until you enable monitoring in settings

**Where Data is Stored:**

 * All performance data is stored locally in your WordPress database on your own
   server
 * No data is sent to external servers or third-party services by default
 * You have full control over data retention periods (configurable from 1-365 days)

**Optional Third-Party Service – Google Analytics 4:**

If you choose to enable the optional Google Analytics 4 (GA4) integration:

 * Core Web Vitals data will be sent to Google Analytics using the Measurement Protocol
   API
 * You must provide your own GA4 Measurement ID and API Secret
 * Data sent to GA4 is subject to Google’s privacy policy and terms of service
 * Google Analytics 4 Privacy Policy: https://policies.google.com/privacy
 * Google Analytics 4 Terms of Service: https://marketingplatform.google.com/about/
   analytics/terms/us/
 * This integration is completely optional and disabled by default

**User Consent:**

 * Site administrators have full control over enabling/disabling data collection
 * Monitoring can be turned off at any time from the plugin settings
 * The plugin does not track individual users or collect personal information
 * All collected data is aggregated and anonymized for performance analysis only

**Data Security:**

 * All REST API endpoints use proper authentication and validation
 * Input data is sanitized and validated before storage
 * Database queries use prepared statements to prevent SQL injection
 * The plugin follows WordPress security best practices

## UKK

### How does this differ from Google PageSpeed Insights?

Google PageSpeed Insights provides lab data from controlled environments. Core Web
Vitals RUM collects data from your actual visitors across different devices, browsers,
and network conditions, giving you more accurate and actionable insights.

### Will this affect my site’s performance?

No. The plugin is designed to have minimal impact on your site’s performance:
 *
Lightweight JavaScript library * Asynchronous data collection * Configurable sample
rates * Optimized database queries

### Is my data secure?

Yes. All data is stored securely on your server. The plugin:
 * Doesn’t collect 
personal information * Anonymizes IP addresses * Uses secure REST API endpoints *
Complies with GDPR regulations

### Can I integrate with Google Analytics?

Yes! The plugin includes full Google Analytics 4 integration:
 * Send Core Web Vitals
data to GA4 * Custom events for each metric * Enhanced reporting capabilities * 
Measurement Protocol API support

### How often is data collected?

You can configure the sample rate from 1% to 100% of your visitors. The plugin also
includes:
 * Real-time data collection * Daily aggregation for better performance*
Configurable data retention periods

### What if I don’t want to collect data from all visitors?

You can adjust the sample rate in the plugin settings. For example, setting it to
10% means only 10% of your visitors will have their Core Web Vitals data collected.
