About the Website Speed Tester
Speed is a ranking factor and, more importantly, a conversion factor — visitors abandon slow pages. Before you can fix speed, you need to measure it: how quickly the server responds, how big the page is, and how many resources it loads.
This Website Speed Tester fetches any public URL server-side and reports response time (TTFB), total load time, page size and resource count, with a simple grade and practical targets.
How to use the Website Speed Tester
- Enter the website URL.
- Run the test — the page is fetched and timed server-side.
- Read the TTFB, total load time, page size and resource count.
- Use the grade and targets to prioritise improvements.
Key features of the Website Speed Tester

- Response time (TTFB), total time, size and resource count
- Clear A–F grade with a score out of 100

How the Website Speed Tester works
This tool is built around the specifications search engines and social platforms actually use: current Google and Bing best-practice guidance for titles and descriptions, the schema.org vocabulary for structured data, and the Open Graph protocol for social sharing. Recommended character limits and tag structures reflect how results are displayed in search and in social feeds.
Everything is generated in your browser, and you can copy the output straight into your site.
Tips & best practices
- A high TTFB points to server or hosting issues; a large page size points to unoptimised images and scripts.
- This test measures from our server — pair it with a field tool like PageSpeed Insights for the real user experience.
- Compressing images (try WebP), caching and reducing scripts are the fastest wins for most sites.
Standards & accuracy
Follows current Google and Bing guidance, the schema.org vocabulary and the Open Graph protocol.
Search engines ultimately decide how to display and rank pages, so treat generated tags and previews as best-practice starting points. Pair them with genuinely helpful content, which remains the most important ranking factor.

Frequently asked questions
Time To First Byte — how long the server takes to start responding after the request. A low TTFB (under about 200 ms) means fast hosting and back-end; a high one slows everything that follows.
This test measures from our server with one request, while lab tools like PageSpeed Insights simulate a device and browser rendering. Both are useful; use them together.
