Comprehensive Website Performance Analysis
The test loads your page in a lab browser and lists what is slow, which files are involved, and how to fix them.
The default run is a mobile lab test. You can run desktop as a separate test. When Google has real-user data, the report shows that too. It does not invent a score when the lab test is unavailable.
Comprehensive Performance Analysis Features
A lab test of one page, plus a plain explanation of what to change
Files from the lab load, with status, size, and time, when Google returns them
Identify render-blocking resources and optimization opportunities
Generate secure links to share performance results with your team
Cached results for faster access with manual refresh option
The default test loads the page as a phone. Desktop is a separate run, not a comparison chart
When the page looks like WordPress, each cause includes a plugin-level fix
Industry standards and optimization targets
Why Website Performance Matters
A slow page costs visits. This test names the cause and the change to make, starting with the largest saving.
Google uses page speed as a ranking factor. Faster sites rank higher in search results.
Faster loading pages lead to higher conversion rates and increased sales.
Fast websites provide better user experience, leading to higher engagement.
Optimize your website speed to reduce bounce rates and increase conversions. Studies show that a 1-second improvement in load time can increase conversions by up to 27%.
Google considers page speed as a ranking factor. Our tool helps you identify and fix performance issues that could be hurting your search engine visibility.
Fast websites create happy users. Our detailed analysis helps you create a smooth, enjoyable experience that keeps visitors engaged and coming back.
Professional-grade analysis with actionable insights
Unlike basic speed tests, our tool provides in-depth analysis of every aspect of your website's performance, from server response times to resource optimization.
Get specific, prioritized recommendations with clear implementation steps. No technical jargon - just practical advice you can act on immediately.
When the lab test returns screenshots, you can play them. If it does not, the report leaves that section out instead of showing a placeholder.
Share detailed reports with your development team, clients, or stakeholders. Secure sharing links make collaboration easy and professional.

The best out there
It loads one public page in a lab browser, then lists what is slow, which files are involved, and how to fix them.
The score and vitals come from a Google lab run of that URL. Lab numbers change with the test conditions. When Google has real-user data for the page, the report shows that separately. If the lab run fails, you get a document-only probe and a note that lab metrics are unavailable.
On a lab run: performance score, Largest Contentful Paint, Total Blocking Time, Cumulative Layout Shift, First Contentful Paint, Time to First Byte, and Speed Index when Google returns them. A missing metric is left out. The report does not show First Input Delay.
The score is the Lighthouse performance score for that lab run, from 0 to 100. It is not a custom blend of page weight and server headers.
Each cause says why it is slow, which files are involved, and how to fix it. WordPress sites also get a plugin-level step. A hosting link appears only when the server response itself is one of the top causes.
We recommend testing your website speed regularly, especially after making changes to your site, adding new content, or updating plugins. Monthly testing helps ensure consistent performance.
Yes! You can share your speed test results with others using our secure sharing feature. This generates a unique URL that displays your test results without exposing sensitive information.
No. When the lab test returns network requests, the report lists file, type, status, size, and time. It is not a browser HAR and it does not show DNS, SSL, or wait phases. If those requests are missing, the table is hidden.
It answers the same question: what is slow, and what should you change. The lab data comes from Google PageSpeed Insights. It does not include GTmetrix video history, a multi-location test, or a full HAR waterfall. Use the Global TTFB Checker when you only need server response from many countries.
Use the full website speed test for overall page load and resources. Use the Global TTFB Checker when you mainly care about server response time from many countries (hosting/CDN latency).
