Test Your Website's Loading Speed
Launch Google PageSpeed Insights and GTmetrix tests with your URL pre-filled. Get Core Web Vitals, performance scores, and optimization recommendations.
Why Is Website Speed Crucial?
Website speed is a critical factor for both user experience and search engine rankings.
Speed = User Experience
Slow-loading pages lead to high bounce rates, frustrated visitors, and lower conversion rates. Users expect pages to load in under 3 seconds, and every additional second increases abandonment.
Speed = SEO Rankings
Page experience and Core Web Vitals are among the signals Google uses in Search. Good performance can support a better user experience, but it does not guarantee higher rankings.
How This Tool Works
This tool is a convenience launcher. Enter your URL and we open Google PageSpeed Insights or GTmetrix in a new tab with your URL pre-filled. These industry-leading services provide the actual performance data.
Mobile vs Desktop
Mobile performance often differs significantly from desktop due to network conditions, device capabilities, and mobile-specific optimizations. Always test both to ensure your site performs well for all users.

Honest by Design — Why We Redirect to Google and GTmetrix
This tool is a convenience launcher, not a speed testing service. Here is exactly what it does and does not do:
- ✓ Opens Google PageSpeed Insights or GTmetrix in a new tab with your URL pre-filled.
- ✓ Saves you the step of manually copying and pasting the URL into those tools.
- ✓ Does not host, run, or store any performance data — Google and GTmetrix provide the actual tests.
- ✓ Does not guarantee performance improvements — speed optimization requires actual changes to your site.
- ✓ The launcher itself requires no signup or payment. The external testing services may have their own account or usage requirements.
This tool does
- Open Google PageSpeed Insights in a new tab
- Open GTmetrix in a new tab
- Pre-fill your URL automatically
- Work entirely in your browser
- Send no data to our server
- Cost nothing to use
This tool does not
- Run its own speed tests
- Show results on this page (Google/GTmetrix do)
- Provide historical performance data
- Replace a full performance monitoring service
- Guarantee performance improvements
- Store the URLs you test
What Does a Modern Website Audit Actually Check?
A speed score is only one part of website quality. Modern audits evaluate six key areas.
Performance
LCP, INP, CLS, FCP, TBT, Speed Index, TTFB — how fast and responsive your site is.
Accessibility
Keyboard navigation, contrast, labels, accessible names, semantic HTML — usability for all users.
Best Practices
HTTPS, browser security, deprecated APIs, console issues, resource handling — technical health.
SEO
Crawlability, indexability, title/meta, links, mobile-friendly basics — search engine readiness.
AI / Machine Readability
Clear structure, semantic HTML, meaningful headings, descriptive links — understandable by automated systems.
Real User Experience
Mobile vs desktop, device capability, network conditions, field data vs lab data — actual visitor experience.
Performance Metrics Explained
These are important performance metrics you'll encounter in PageSpeed Insights and other performance reports.
Core Web Vitals
LCP (Largest Contentful Paint)
How quickly the main content becomes visible. It's a key indicator of perceived loading speed.
Good: ≤ 2.5 secondsINP (Interaction to Next Paint)
How quickly the page responds to user interactions. This replaced FID as a Core Web Vital in March 2024.
Good: ≤ 200 millisecondsCLS (Cumulative Layout Shift)
How stable the page remains while loading. A high CLS means elements shift around, which is a poor user experience.
Good: ≤ 0.1Other Useful Diagnostics
FCP (First Contentful Paint)
When the first visible content appears on the screen.
Good: ≤ 1.8 secondsTBT (Total Blocking Time)
How long the main thread is blocked during the lab test, preventing user interaction.
Good: ≤ 200 millisecondsSpeed Index
How quickly visible content is progressively displayed during loading. Lighthouse calculates it from the visual progression of the page.
Good: ≤ 3.4 secondsTTFB (Time to First Byte)
How quickly the browser receives the first response from the server.
Good: ≤ 800 millisecondsWhy Do PageSpeed, GTmetrix & DevTools Show Different Results?
Different tools use different testing conditions, which naturally produces different scores.
📊 Google PageSpeed Insights
Best for: Search + real-world UX
Lighthouse lab testing + available Chrome UX field data
⚡ GTmetrix
Best for: Detailed performance analysis
Controlled test environment, waterfall, location/device/network options
🔧 Chrome DevTools
Best for: Developer debugging
Runs on your own browser/device and lets you inspect runtime behavior
👥 Real User / Field Data
Best for: Actual visitors
Based on real users rather than one synthetic test
Why Your Score Changes Between Tests
Same URL ≠ Same Test Conditions. Results can differ because of:
- Different device or CPU speed
- Mobile vs desktop testing
- Network throttling and connection speed
- Geographic location and routing
- Server response time variations
- CDN/cache state (cold vs warm cache)
- Ads and third-party scripts loading differently
- Test timing and browser conditions
- Lighthouse/GTmetrix version changes
Bottom line: Don't compare scores unless the test conditions are reasonably consistent.

Website Speed Test FAQs
Answers based strictly on what this tool does and how website speed works.
Which testing service should I use?
Google PageSpeed Insights is best for seeing how Google views your site's performance and Core Web Vitals. GTmetrix provides detailed technical analysis with waterfall charts. Use both for a complete picture of your site's performance.
Why does this tool open a new tab?
Website speed testing is a complex process requiring specialized infrastructure. This tool acts as a quick launcher for the official, industry-leading services to ensure you get the most accurate and detailed reports directly from the source.
What is a good PageSpeed score?
Google considers 90–100 as "Good," 50–89 as "Needs Improvement," and 0–49 as "Poor." Aim for 90+ on both mobile and desktop, but focus on the specific Core Web Vitals metrics rather than just the overall score.
Why is my mobile score lower than desktop?
Mobile Lighthouse tests use simulated mobile conditions, including CPU and network throttling, so results can differ significantly from desktop. Optimize images, reduce JavaScript, and improve responsive performance for mobile users.
Do Core Web Vitals affect SEO?
Core Web Vitals (LCP, INP, CLS) are part of Google's page experience signals. Sites with poor Core Web Vitals may rank lower than competitors with better performance, all else being equal, but they are one factor among many.
Is my data secure when using this tool?
Yes. This tool sends nothing to our server. It only opens links to Google PageSpeed Insights or GTmetrix in a new tab. The URL you enter is passed directly to those services through the URL — we don't see, store, or log it.
How often should I test my site's speed?
Test after every major change (new theme, plugin, content update). For ongoing monitoring, test weekly or use a dedicated performance monitoring service that alerts you to regressions automatically.
Can I test any website?
Yes — any publicly accessible URL can be tested. However, sites behind authentication, very new sites, or sites blocking crawlers may not be testable. For those, use browser developer tools (F12 → Network tab) to measure performance locally.
