How to run a reliable speed test
Performance can vary by network, device, and caching. Follow these steps to get results you can trust before you start changing things.
Start with your homepage and your most important landing pages. Different templates can behave very differently.
Run at least two tests and compare. One run can be noisy due to temporary network or server conditions.
Mobile devices are typically slower and more sensitive to heavy JavaScript and large images.
Apply a single optimization, then re-test. This makes it obvious what helped—and what didn’t.
Tip: avoid “false wins”
Some optimizations improve lab scores but hurt real UX (for example, delaying critical UI behind a loader). Prioritize changes that reduce real work: lighter images, less blocking code, faster responses.
Metrics glossary
These short definitions help you understand what a report is actually measuring—without digging through docs.
LCP
How quickly the main content becomes visible. Often affected by images, fonts, and server speed.
INP
How responsive the page is to user interactions. Usually impacted by heavy JavaScript and long tasks.
CLS
How stable the layout is while loading. Common issues are missing image sizes and late-loading UI elements.
TTFB
How quickly the server starts responding. Influenced by hosting, caching, and backend work.
FCP
When the first visible content appears. Sensitive to render-blocking CSS/JS and font loading.
Waterfall
A timeline showing which requests block rendering. Great for spotting slow images or third‑party scripts.
Frequently Asked Questions
Common questions about our speed test
How accurate is the speed test?
Our speed test uses real browser engines and simulates real-world conditions. We test from multiple locations and devices to provide comprehensive performance data that reflects actual user experiences.
What metrics do you measure?
We measure all Core Web Vitals (LCP, CLS, INP), load time, page size, request count, and provide detailed waterfall charts. You'll also get recommendations for improving each metric.
How often should I test my site?
We recommend testing your site regularly, especially after making changes. Monthly testing is good for monitoring, while weekly testing is ideal during optimization efforts.
Can I test password-protected sites?
Currently, our tool tests publicly accessible pages. For password-protected or staging sites, you may need to use browser-based testing tools or temporarily make the page public.
What's a good PageSpeed score?
A score of 90+ is considered excellent, 50-89 needs improvement, and below 50 is poor. However, focus on the specific Core Web Vitals metrics rather than just the overall score.
Next steps after you get your results
Once you know what’s slow, pick the smallest change that targets the bottleneck, then re-test.
If loading is slow
Focus on the pages’ largest images, font loading, and server response time.
- • Read the LCP guide
- • Check TTFB basics
- • Consider tools from Best Tools
If the site feels laggy
Reduce heavy JavaScript work and long tasks that block interactions.
- • Read the INP guide
- • Audit third-party scripts
- • Ship one change at a time and re-test
If things jump around
Reserve space for images/ads and avoid late-loading layout shifts.
- • Read the CLS guide
- • Add explicit image sizes
- • Avoid injecting UI above content

How to interpret your results
After running a test, focus on the Core Web Vitals first, then dig into secondary metrics and detailed waterfall views.
Green scores
If most metrics are in the green zone, avoid chasing tiny wins. Instead, concentrate on reliability across devices and network conditions.
- • Confirm good scores on mobile
- • Check real-user data where available
- • Monitor over time for regressions
Yellow scores
Yellow usually means "almost there". A few targeted fixes — image compression, caching, or script deferral — can often push you into the green.
- • Prioritize templates with the most traffic
- • Fix the slowest metric first (LCP, INP, or CLS)
- • Re-test after each deployment
Red scores
Red scores signal structural performance issues. Plan a short project to address the root causes instead of quick hacks.
- • Audit third-party scripts and heavy plugins
- • Review hosting, CDN, and caching setup
- • Consider a design or theme refresh if needed
Remember: synthetic tests are just one input. Always combine them with analytics and business KPIs to decide which optimizations actually matter for your users.
