What this audit checks
This audit runs 9 distinct categories of analysis using real APIs from Google, Mozilla, and the Internet Archive. No shortcuts, no fake numbers.
Performance
Lighthouse Performance score from Google PageSpeed Insights, plus Core Web Vitals (LCP, CLS, TBT).
Accessibility
Lighthouse Accessibility score. Catches contrast issues, missing alt text, form-field labelling, ARIA roles.
Best Practices
Lighthouse Best Practices score. Catches mixed content, deprecated APIs, console errors.
Mobile
A separate Lighthouse run on a simulated phone, with its own scores, because a page often loads and looks different on a phone.
On-Page SEO
Title length, meta description, H1 presence, heading hierarchy, word count, image alt text, internal linking, OG tags, schema markup.
Technical SEO
HTTPS, the page's response code, canonical tag, language and character set, plus Google's own Lighthouse SEO check.
Security headers
Live grade from Mozilla HTTP Observatory. CSP, HSTS, X-Frame-Options, Referrer-Policy, cookie security.
Domain age
First archived date via the Wayback Machine, a quick sign of how long the site has been online.
HTML validation
W3C standards check. W3C's public validator often refuses automated requests, so this check may show as unavailable.
What this audit uses, and its limits
Every number in this report comes from a live check of the URL you enter. There is no email gate before the detail, and no score made up to fill a chart.
The audit calls Google's PageSpeed Insights API for Lighthouse scores and Core Web Vitals, Mozilla's HTTP Observatory for the security-header grade, and the Wayback Machine archive for domain age. The on-page and technical checks come from our own server reading your page's HTML. There is no middle layer and no invented figure: what you see is what Google and Mozilla return for your URL.
Why is it free? A useful free tool means the people who contact us already know their scores and roughly what needs doing. That makes for a better first conversation than a list of collected email addresses.
For checking a handful of pages, you do not need a monthly subscription or an account. This page gives you the underlying Google and Mozilla data directly, for free.
It has limits. This is a single-page audit, not a whole-site crawl: it analyses the exact URL you enter. It does not reliably render JavaScript-heavy single-page apps, because it reads server HTML rather than running a full browser. And it does not include backlink data, which needs a separate link index. For one page, on real data, it gives you a clear list of what to fix first.
How to read your results
Lighthouse scores (Performance, Accessibility, Best Practices, Mobile)
Each Lighthouse score is colour-banded the way Google bands them: 0 to 49 is red, 50 to 89 is amber, and 90 to 100 is green. Red means a real problem worth fixing soon; amber means there is room to improve but nothing is on fire.
A score of 70 is not a failure. Treat it as something to improve on next, not a verdict on your site. And expect your mobile scores to land roughly 10 to 20 points below desktop. That gap is normal: mobile is simulated on a slower CPU and network, and almost every site shows it.
On-Page and Technical SEO scores
These two scores are computed in-house from real checks against your page: title length, H1 count, heading hierarchy, schema markup, canonical tags, HTTPS, and more. They are not Lighthouse numbers; they are our own scoring of concrete, observable facts.
A low score here is almost always cheap to fix. Missing meta descriptions, a duplicate H1, or an absent canonical tag are minutes of work each, so these are usually quick to fix.
Security headers (letter grade)
Mozilla HTTP Observatory grades your response headers on an F-to-A+ scale. Many WordPress and off-the-shelf sites score low out of the box, not because they are insecure, but because hardening headers are simply not configured by default.
The good news is that this is one of the fastest wins available. Adding three or four headers (a Content-Security-Policy, HSTS, X-Content-Type-Options and a Referrer-Policy) through Cloudflare or your hosting panel is often a quick change.
The 3 things to fix first
Your results open with the biggest problems on the page, at most three, each in one plain sentence: what is wrong and why it matters to your business. They are picked from the same checks as the detailed results, most serious first.
If your page has fewer than three real problems, you see fewer, and a note that the rest looks good. If Google's speed test was unavailable, the summary says so, because speed could not be part of it.
Top recommendations
The "Top fixes" list further down is ordered by how serious each problem is, not by how easy it is to fix. Open a card to see why it matters and the steps to fix it, which you can hand to whoever looks after your website.
You do not need to do everything at once. Start with the 3 things to fix first, then run the audit again to see what has changed.
Frequently Asked Questions
How long does the audit take?
Usually 10 to 30 seconds. The Google PageSpeed Insights call is the slow part: it runs a full Lighthouse pass on a real device profile. The on-page, security and domain checks complete in parallel, so the wait is mostly Google.
Do you store the URL or my data?
The audit runs server-side and the result is held in memory for about ten minutes so a refresh is instant. We do not write your URL to a database, sell it, or share it. The report download is built in your browser, and nothing is emailed.
Why is one section showing "unavailable"?
Some upstream APIs rate-limit or bot-challenge automated requests. When that happens the audit degrades gracefully: the section is marked unavailable instead of showing a fake number, and the rest of the report is unaffected. If Google's speed test fails or its daily limit runs out, you will see "Speed check unavailable today" and speed is left out of the score rather than counted as zero. Re-running later often succeeds.
Can I audit my whole site at once?
Not with the free tool: it audits one URL per run. A review of your whole site, with a prioritised fix list and a 30-minute walkthrough call, is our £295 SEO Audit. Run a few key pages here first to see where you stand.
How accurate are the Lighthouse scores?
They come straight from Google’s PageSpeed Insights API, the same Lighthouse engine built into Chrome DevTools. Lab scores naturally vary a few points between runs because they simulate a fixed device and network, so treat them as a reliable range rather than an exact figure.
Does Google use this same data?
Partly. PageSpeed Insights is Google’s own tool, and Core Web Vitals (LCP, CLS and interaction latency) are part of how Google judges page experience. For search, Google uses data from real visitors in Chrome, which can differ from these lab scores, so treat a better score here as a sign the real numbers should improve too.
Why does it say the site's security check blocked us?
Some sites sit behind a firewall or bot filter (Cloudflare, Sucuri, SiteGround and others) that answers automated requests with a check page instead of the site. We do not score that page, because the score would describe the firewall, not your site. Try again later, or message us on WhatsApp to ask for a check by hand.
Can I keep a copy of the report?
Yes. Use "Download report" under the results to save it as a file you can open in any browser, print or save as a PDF. It is built in your browser, so nothing is emailed or stored.
