Understand what is slowing your website
A website speed test that explains what is wrong
A single score is not enough. Website Scorer shows why a website is slow, whether it works properly on mobile and which changes are most likely to help visitors.
Search engine checks
Check whether titles, descriptions, headings, canonical URLs, robots, sitemap and structured data are helping search engines understand the page.
Mobile experience
Find out whether the page is easy to use on a phone and whether images, layout or technical settings may be slowing mobile visitors down.
Accessibility and usability
Check language settings, image descriptions, form labels, page landmarks and automated signals that can affect how easily people use the site.
Security and trust
See whether HTTPS, redirects and important response headers provide the basic signals visitors and browsers expect from a trustworthy website.
Contact and customer actions
Check whether visitors can easily find calls to action, contact details, forms and privacy information when they are ready to call, book or enquire.
More than a website speed checker
Check whether your website is working properly
A page can open and still frustrate visitors. The overall score balances speed, mobile use, search visibility, accessibility, security, content and the path to contacting your business.

Helpful answers
Common questions about slow websites
Why is my website slow?
A website can be slow because of large images, a slow server, too many scripts, third-party services, unoptimised fonts or weak cache settings. Website Scorer checks the page and highlights the issues most likely to affect loading speed.
Why is my website loading slowly even when it works for me?
Your browser may already have saved some files, while a new visitor has to download everything for the first time. Connection speed, device performance, hosting load and external services can also make the same page feel different for different people.
Why is my website slow on mobile?
Phones often use slower connections and have less processing power than desktop computers. Heavy images, complex scripts and layouts that are not mobile-friendly therefore cause more noticeable delays on mobile devices.
How can I check my website speed?
Enter a public website address and start the free website speed test. The report checks mobile and desktop performance, Core Web Vitals and other technical signals, then shows which improvements should be handled first.
Is my website working properly if it opens?
Not necessarily. A page can open but still load slowly, work poorly on mobile, hide important content from search engines, miss security headers or make it difficult for visitors to call, book or send an enquiry.
Is Website Scorer a free website test?
Yes. Website Scorer provides a focused automated check of a public webpage without requiring an account or payment.
Does the report replace a professional audit?
No. It is an automated screening report designed to reveal likely priorities. It is not a penetration test, legal opinion, manual SEO review or full accessibility conformance audit.
Why can a score change between tests?
Websites, hosting load and laboratory measurements change. Reports are cached briefly to reduce repeated load, so a later uncached test can produce a different result.
Will Website Scorer crawl my whole site?
No. The current version focuses on the submitted public page and a small number of essential resources such as robots.txt and sitemap.xml.
