What does the Page Speed Analyzer do?

The Page Speed Analyzer from PowerSEOTools.online measures how fast a web page responds from our server, including DNS lookup time, time to first byte (TTFB), total load time, HTML size and key assets.

Is this the same as Google PageSpeed Insights?

This tool provides a lightweight, server-based view of speed metrics and page weight. It is not a full Lighthouse or PageSpeed Insights audit, but it gives quick, practical data you can use alongside those tools.

Does the Page Speed Analyzer work on mobile and desktop?

Yes. You can choose a simulated desktop or mobile device profile. We change the user-agent string accordingly, but the measurements are still taken from our server location.

Is the Page Speed Analyzer free to use?

Yes. The Page Speed Analyzer is completely free with no registration. You can run as many checks as you want, within reasonable usage limits.

Why do results sometimes differ from other speed tools?

Different tools use different testing locations, device profiles and metrics. Our Page Speed Analyzer shows how a page performs from our server, which may have different latency compared to your users or other testing services.

Page Speed Analyzer

Check how quickly a page responds from our server, including DNS time, time to first byte (TTFB), total load time, page weight and key assets. Use it alongside Lighthouse or PageSpeed for a complete picture.

Website URL

Enter the full URL of the page you want to test, including https:// where possible.

Device profile

We change the user-agent to imitate a desktop or mobile browser. Tests still run from our server location.

Free Online Page Speed Analyzer

The Page Speed Analyzer from PowerSEOTools.online gives you a quick, practical view of how fast a page responds from our server. It measures DNS lookup time, time to first byte (TTFB), total load time and approximate page weight based on HTML and key assets.

How to Use the Page Speed Analyzer

Enter the full URL of the page you want to test.
Choose a device profile (desktop or mobile) to change the user-agent string.
Click Analyze Speed and wait a few seconds while we load the page from our server.
Review the performance score, TTFB, total load time and estimated page weight.
Check the resource breakdown to see which images, CSS and JS files contribute to page size.
Use the optimization suggestions as a checklist for further improvements.

What Do the Metrics Mean?

TTFB (Time to First Byte): How long it takes for the first byte of the response to reach the browser after the request is sent. High TTFB often points to server performance or backend issues.
Total load time: Approximate time until all data for the page is downloaded from our server’s point of view.
HTML size: Size of the raw HTML document.
Estimated page weight: Combined weight of the HTML and a sampled subset of images, stylesheets and scripts.
Requests analyzed: How many individual HTTP requests we measured for this test.

Why Use This Tool Together with Lighthouse?

Google’s Lighthouse and PageSpeed Insights provide in-depth audits and lab-based metrics like LCP, CLS and FID. Our Page Speed Analyzer focuses on a lightweight, server-based snapshot you can run quickly and often. Using both together gives you a more complete picture of performance from different perspectives.

Improving Your Page Speed

Enable HTTP caching and use a CDN to reduce TTFB for global users.
Compress images with modern formats like WebP/AVIF and serve appropriately sized images.
Minify and combine CSS and JavaScript files to reduce requests and file sizes.
Defer or lazy-load non-critical scripts, such as analytics or chat widgets.
Remove unused CSS and JavaScript, especially from heavy frameworks or theme bundles.

Use this free Page Speed Analyzer regularly as you iterate on your site, then validate your improvements with more detailed tools like Lighthouse and Search Console.
