Free website audit

What this tool checks

• SEO

  Title and description, headings, canonical URL and where it points, indexing rules, image descriptions, JSON-LD structured data (parse errors and missing key properties), social previews, and your robots.txt and sitemap.

• Speed

  A Google Lighthouse lab test of how quickly the page shows content and becomes usable, with each metric compared to its published threshold and the files behind every slow audit. If Lighthouse can't run, a clearly labelled quick check takes its place.

• Mobile experience

  The page opened at phone, tablet and desktop sizes: whether the viewport tag is present, uses width=device-width and allows zooming, and which elements stick out past the screen edge.

• Accessibility

  Automated WCAG rules from axe-core — missing labels, low contrast, images without text alternatives, ARIA mistakes and more — with the affected elements and the rules that need a person to review.

• Website security

  HTTPS and the http→https redirect, the TLS certificate, the values of your security headers (HSTS, CSP, framing and more), cookie flags, CORS, mixed content and security.txt. Passive and read-only.

• Links, forms & page errors

  Up to 12 links to your own pages and 5 to other sites, files that fail to load, JavaScript errors, and the markup of each form — which is never submitted.

• Server & availability

  Whether your homepage and common files such as robots.txt and sitemap.xml respond, whether any return server errors, and the average response time.

How the check works

What this audit does not check

• Your other pages

  Every check looks at the one address you enter. Duplicate titles, orphan pages and broken links elsewhere need a site scan.

• Pages behind a login

  We only see what loads publicly. Nothing is signed into, and no form is submitted.

• Security testing beyond configuration

  It isn't a penetration test: no exploitation, no vulnerability scanning of your software or its dependencies, no server-side code review.

• Real-visitor speed

  Speed is one lab run. Field data and Interaction to Next Paint (INP) come from real visitors, for example in Google Search Console.

• Rankings and content quality

  No keyword research, ranking or traffic data, backlinks, or judgement of whether your content is useful.

Common problems we find

• Missing or badly sized page titles and descriptions

  Titles that are empty, generic (“Home”) or longer than about 60 characters, and pages with no meta description, so search engines write their own snippet.

• Large, slow-loading images

  Photos far bigger than the space they're shown in are one of the most common reasons a page is slow to show its main content.

• Missing or weak security headers

  No HSTS or Content-Security-Policy header is very common, and so is a CSP that allows 'unsafe-inline' scripts or an HSTS max-age of only a few minutes.

• Images and buttons without text

  Images without alt text and icon-only buttons without a name leave screen reader users guessing.

• Low colour contrast

  Light grey text on white, or text over busy images, that many people find hard to read.

• Broken links, failed files and JavaScript errors

  Links to pages that were moved or deleted, scripts or images that return 404, and scripts that fail while the page loads.

How to fix them

1. 1

   Start with the “Fix first” list

   The report puts the most serious problems that are quickest to fix at the top. Work through those before anything else.

2. 2

   Take the quick wins

   Titles, descriptions, alt text and most security headers are small edits in your CMS or server settings, and they often lift a score noticeably.

3. 3

   Plan the bigger jobs

   Speed and layout problems usually need changes to images, scripts or templates. Each issue in the report explains why it matters and what to change.

4. 4

   Check again after each change

   Run the audit again once you've made a fix, to confirm it worked and nothing else broke.
