What early users are saying

“Ran it against three client sites and it picked up issues our previous tool had missed. The report is readable enough that I could hand it straight to a non-technical client.”

“Quick sanity check before a launch. Caught two blocking SEO issues and a slow LCP on the pricing page. Ten quid well spent.”

Frequently asked questions

What does Site Diagnostics check?
Site Diagnostics checks five key pillars: SEO (meta tags, headings, canonical URLs, structured data), Performance (page speed, Core Web Vitals, JavaScript bundle size), Security (HTTPS, security headers, CSP, exposed files), Content & Links (word count, internal linking, broken links), and Design & UX (accessibility, mobile responsiveness, form labels). The free snapshot gives you a grade and top issues; the full report provides detailed fixes for every finding.
Is the initial website scan really free?
Yes — the initial scan is completely free. You enter your URL, we analyse it, and you get an instant grade plus your top critical issues at no cost. The detailed 10+ page report with AI-generated fixes and step-by-step guidance is £9.99, delivered to your inbox.
How long does the audit take?
The free snapshot typically completes in 15–30 seconds. The full paid report is generated by AI and delivered to your email within a few minutes of purchase.
Does it work for any type of website?
Yes. Site Diagnostics works with any publicly accessible website — WordPress, Shopify, Webflow, custom-built Next.js or React sites, and everything in between. It checks the live URL you provide, so whatever your tech stack, it analyses what visitors and search engines actually see.
Is my website data kept private?
Yes. We only fetch publicly available information from the URL you submit — the same data any search engine or browser would access. We don't store your site's content and don't share scan data with third parties. Full details are in our Privacy Policy.
