Stop guessing about your site’s performance. Rayetun Site Monitor gives you real-user Core Web Vitals data collected directly from your visitors’ browsers — no external account, no API key, no tracking from third parties.
Activate it. Visit a few pages. Within seconds you’ll see live performance metrics on your WordPress dashboard.
<h3>⚡ Why This Plugin?</h3>
Unlike Search Console (which shows aggregated, delayed data), Rayetun Site Monitors every page in real-time from the moment of activation. No sample-size thresholds. No waiting for Google to collect data. Just instant, actionable insights.
<ul>
<li>🎯 Zero configuration — activate and data flows immediately</li>
<li>📊 Real users, real data — field metrics from actual visitors (not synthetic robots)</li>
<li>🔒 Your data stays yours — everything lives in your WordPress database</li>
<li>⚡ No impact on performance — sub-4KB beacon, loaded with defer, zero blocking</li>
<li>🔐 GDPR-friendly — no cookies, no third-party data sharing</li>
</ul>
<h3>📈 What It Measures</h3>
The plugin tracks all five Core Web Vitals and presents them with Google’s official thresholds:
 Metric 
 Target 
 What It Means
 LCP — Largest Contentful Paint 
 ≤ 2.5s 
 How fast your main content appears
 CLS — Cumulative Layout Shift 
 ≤ 0.1 
 How stable your page layout stays
 INP — Interaction to Next Paint 
 ≤ 200ms 
 How responsive your site feels to clicks
 FCP — First Contentful Paint 
 ≤ 1.8s 
 How fast anything appears on screen
 TTFB — Time to First Byte 
 ≤ 800ms 
 How quick your server responds
<h3>🖥️ The Dashboard</h3>
A single glance tells you everything about your site’s performance:
<ul>
<li>Score cards — P75 value per metric with color-coded Good / Needs Improvement / Poor badges</li>
<li>Distribution bars — see at a glance what % of page loads fall into each rating band</li>
<li>Sparkline trend charts — watch how each metric improves (or worsens) over 7, 14, or 30 days</li>
<li>Slowest Pages ranking — which URLs need the most work, sorted by LCP</li>
<li>Device split — toggle between All Devices, Mobile Only, or Desktop Only</li>
<li>Date range & URL filters — drill into specific time periods and individual pages</li>
</ul>
<h3>🔍 LCP Element Attribution</h3>
“My LCP is slow. But what is slow?”
Rayetun Site Monitor answers that automatically. The beacon captures the exact DOM element responsible for Largest Contentful Paint — whether it’s a hero image, a video embed, a heading, or a background. See the element tag, CSS class, and image source right alongside the metric.
No guesswork. No DevTools digging. Just answers.
<h3>🧪 PageSpeed Insights Lab Tests</h3>
Click PSI ↗ on any page row and Google’s lab test runs instantly inside your WordPress admin. Compare your real-user data (Field LCP P75) with Google’s synthetic lab test in a single view:
<ul>
<li>Lab performance score</li>
<li>Lab metrics: LCP, FCP, CLS, TBT</li>
<li>Field LCP P75 (real-user percentile)</li>
<li>Failed Opportunities list (unused JS, render-blocking resources, unoptimized images)</li>
<li>One-hour result caching to stay under API limits</li>
</ul>
No plugin configuration needed — the plugin works without an API key. Add a free key to get 25,000 requests/day instead of 25.
