Free website audit
Enter a page of your website and we'll run all seven of our checks on it: SEO, speed, mobile layout, accessibility, security, links and page errors, and server availability. You get one report with a score for each area and a short list of what to fix first.
What this tool checks
SEO
Page title and description, headings, canonical URL, indexing rules, image descriptions, structured data, social previews, and your robots.txt and sitemap.
Speed
A Google Lighthouse test of how quickly the page shows content and becomes usable, with the audits that are slowing it down.
Mobile experience
The page opened at desktop, tablet and phone sizes, with screenshots, a check for the viewport tag and for content wider than the screen.
Accessibility
Automated WCAG rules from axe-core: missing labels, low contrast, images without text alternatives, ARIA mistakes and more.
Website security
HTTPS, the SSL/TLS certificate (validity, protocol and expiry date) and the security headers your server sends.
Links & page errors
Up to 12 links to other pages of your own site, tested for errors, plus JavaScript errors that happen while the page loads.
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
We visit the page you enter the way a browser would and run seven independent checks on it. The mobile, accessibility and links checks use a real Chromium browser, speed uses Google Lighthouse, and the SEO, security and server checks make direct requests to your site.
Each area gets a score from 0 to 100. Most start at 100 and lose points for each problem found; speed uses Lighthouse's own score. The overall score is the average of the areas we could check — if an engine isn't available, that area is left out rather than counted as zero.
The audit covers one page. With a free account you can also scan several pages of your site in one go and keep track of your websites.
Common problems we find
Missing or badly sized page titles and descriptions
Titles that are empty, very short 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 security headers
No HSTS or Content-Security-Policy header is very common, even on sites that already use HTTPS.
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 internal links and JavaScript errors
Links to pages that were moved or deleted, and scripts that fail while the page loads.
How to fix them
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.
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.
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.
Check again after each change
Run the audit again once you've made a fix, to confirm it worked and nothing else broke.
Frequently asked questions
Is the website audit really free?
Yes. You can audit a page without an account. Free checks are limited to a few per hour and per day for each network so the service stays available for everyone; a free account raises that limit.
How long does an audit take?
Usually one to two minutes. Most of that time is the speed test and the browser-based checks, which load your page several times.
Does it check my whole website?
No, it checks the one page you enter. To scan several pages of a site together, create a free account and start a site scan from your dashboard.
Why is one of the areas missing from my report?
Some checks need a browser engine or Lighthouse running on our server. If one isn't available at that moment, we leave that area out and calculate the overall score from the areas we could check, instead of guessing.
Why does my score change when I run the audit again?
Speed in particular varies from one page load to the next, depending on network conditions, server load and third-party scripts. Other areas only change when the page itself changes.
What happens to the results?
Your report is available through its private link. Analyses, including screenshots, are deleted automatically after 24 hours.
