Page Speed Essentials
Why Speed Matters for SEO
Google uses page speed as a ranking factor. Faster pages earn better rankings, lower bounce rates, and higher conversions.
🏆
Core Web Vitals are Ranking Signals
LCP, FID, and CLS directly affect your Google rankings since the Page Experience update. Scoring "Good" on all three can boost organic traffic.
🖼️
Images are the #1 Speed Killer
Unoptimized images account for 60–70% of page weight on average. Compress images, use WebP format, and enable lazy loading to save seconds.
💾
Browser Caching Saves Repeat Visits
Set long cache headers for static assets (CSS, JS, images). Returning visitors load your pages up to 80% faster with proper caching configured.
🌐
Use a CDN for Global Delivery
A Content Delivery Network (CDN) serves assets from servers closest to each visitor. This alone can cut TTFB by 200–500ms for distant users.
📜
Minify & Defer Render-Blocking JS
JavaScript that blocks rendering is one of the biggest LCP killers. Minify scripts, use defer/async attributes, and eliminate unused JS.
⚡
TTFB Starts at Your Server
Time to First Byte is controlled by your hosting. Upgrade to faster hosting, enable server-side caching, and use HTTP/2 to dramatically reduce TTFB.
Frequently Asked Questions
What does the Page Speed Analyzer measure?
It measures your website's performance score (0–100), Core Web Vitals (LCP, FID/INP, CLS), Time to First Byte (TTFB), First Contentful Paint (FCP), Speed Index, Total Blocking Time (TBT), and Time to Interactive (TTI). It also identifies specific opportunities to save load time and diagnoses performance issues.
What is a good page speed score?
Google's scale: 90–100 is Fast (green), 50–89 is Needs Improvement (amber), and 0–49 is Slow (red). For SEO and conversions, you should aim for 90+ on desktop and 70+ on mobile. Mobile scores are typically 20–30 points lower due to network and device constraints.
What is LCP and why does it matter?
LCP (Largest Contentful Paint) measures when the largest visible element on your page finishes loading — typically a hero image or heading. Google considers LCP under 2.5 seconds as Good. Poor LCP (above 4s) can directly lower your rankings and hurt user experience. It's the most impactful Core Web Vital to optimize.
Why does my mobile score differ from desktop?
Mobile analysis simulates a mid-range Android device on a 4G connection, while desktop uses a faster CPU and broadband. Mobile scores are almost always lower because devices are slower and networks are less reliable. Google uses mobile-first indexing, so mobile performance is more important for SEO rankings.
How do I improve my page speed score?
The highest-impact fixes are: (1) Compress and convert images to WebP, (2) Enable browser caching, (3) Use a CDN, (4) Minify and defer JavaScript, (5) Minimize render-blocking CSS, (6) Upgrade to fast hosting with HTTP/2. Each opportunity in this tool shows the estimated time savings so you can prioritize the fixes that matter most.
Is this tool free and does it require login?
Yes — RankSorcery's Page Speed Analyzer is completely free and requires no account or login. You can analyze any public URL, switch between mobile and desktop modes, and get full performance reports with actionable fix recommendations instantly.
