FREE WEBSITE AUDIT EXPLAINED
How does the free SiteAudit AI website audit work?
See how SiteAudit AI checks a public homepage using Google Lighthouse, what the performance and SEO results mean, and how to download the free PDF report.
What happens when you check a website?
- Enter a public website URL. SiteAudit accepts the address of a publicly accessible homepage. It does not sign in, inspect private files or spider every page.
- Run mobile and desktop measurements. Google's PageSpeed Insights service performs Lighthouse analysis. Availability and measurement times depend on Google's service and the target website.
- Review a preview. See available category scores and selected findings in the browser. A Lighthouse score is a lab measurement, not a guarantee about rankings or sales.
- Unlock the PDF immediately. Enter your name, role, organisation and email to download your SiteAudit AI report. There's no payment or email-verification step. Promotional consent is separate and optional.
Which Lighthouse categories are included?
- Performance
- Loading speed and interaction-related laboratory measurements, where Google provides them.
- Accessibility
- Automated signals that identify some potential accessibility problems. Human testing remains necessary.
- Best practices
- Technical and browser-related quality checks in Google's Lighthouse framework.
- SEO
- A limited set of technical discoverability checks. These cannot assess your actual keyword positions, site architecture or content strategy.
What the free audit does not cover
The free tool is not a full technical website crawl. It does not inspect every page, backlinks, conversion funnels, competitor keywords, complete structured-data coverage, compliance with WCAG, or your brand's position in AI-generated answers. A single homepage score is useful as a starting point, but it is not a complete website diagnosis.
What is the difference between lab and field performance data?
Lab data comes from a controlled test and helps identify reproducible opportunities. Field data reflects how actual visitors experience a website. They can differ by device, connection, traffic mix and time. The free SiteAudit PDF reports the Lighthouse data that was actually returned; it does not invent missing field measurements.
When should you request a deeper assessment?
If you depend on organic leads, sell online, operate across many service pages or have technical indexing problems, an assessment spanning the whole website can add sitemap and crawl analysis, information architecture, search intent, accessibility review, content quality and prioritised engineering work. BU1ST Technologies offers separately scoped, advanced website crawls and tailored technical assessments. Enquire with BU1ST about an advanced crawl ↗.
