What the free SEO check looks at
XKey runs around 50 checks across ten areas, each weighted by how much it affects your rankings. You get an overall score out of 100, a score for each area and a "fix these first" list sorted by impact.
Indexing & crawling
Status code, noindex, robots.txt rules, XML sitemap, canonical tag, redirect chains, www and https consistency.
AI search readiness
Whether search and AI crawlers are allowed in, llms.txt, entity markup, question-led content, freshness and trust pages.
Search snippet
Title and meta description measured in pixels like Google, plus Open Graph and social cards.
Content quality
Word count, readability, topic focus against your title, H1 and heading structure.
Real-world speed
Core Web Vitals from real Chrome users where available, plus a Lighthouse lab test.
Structured data
JSON-LD validity and Google's required properties for your business type.
Links
Internal linking, anchor text and a live broken-link test on a sample of your links.
Security, mobile & local
HTTPS, security headers, mobile viewport, accessibility basics and LocalBusiness signals.
Why most free SEO checkers miss AI search
A growing share of people now ask ChatGPT, Claude, Perplexity or Google's AI Overviews instead of scrolling through ten blue links. Those assistants can only recommend a business they're allowed to crawl and can clearly understand. A site can rank on Google and still be invisible to AI because its robots.txt blocks the crawlers, its business details aren't marked up, or it never answers questions directly. XKey scores this separately as AI search readiness, so you can see both sides at once. Read more in our guide to AI search optimisation.
How to use your SEO report
- Start with the fix list. It's sorted so the changes with the biggest effect come first – usually indexing problems, missing titles or a missing H1.
- Check the critical items. Anything marked critical can stop a page ranking at all.
- Re-run the check after each change. Reports are cached for an hour, so add a small change to the address (such as a trailing slash) if you need a fresh one sooner.
- Check the whole site. A single page can look perfect while problems elsewhere hold you back – run a full website audit next.
Is this SEO check really free?
Yes, completely. No cost, no sign-up, no email address, no subscription, no trial that runs out and no "upgrade to see your results". You get the whole report straight away. The instant tools run in your browser and are unlimited; full checks only have a safety limit set far above normal use, to stop bots. XKey is made by IceWork, a small web studio in Blackpool, as a free tool for UK businesses – if you'd like the fixes done for you, IceWork can help, but you never have to.
Frequently asked questions
How accurate is the score?
Every check is based on what Google and the AI providers document publicly, and title widths are measured in pixels the way Google displays them. The score is a guide to how well-prepared a page is – no tool can guarantee rankings, because Google also weighs links, competition and many other signals.
Do you store my website's content?
No. We fetch the page like a search engine would, analyse it and keep only the finished report in a short-lived cache for an hour so repeat views are fast.
Is there a limit on how many sites I can check?
Not for normal use. The instant tools run in your browser and are unlimited. Full checks and audits only have a safety limit set far above what a person can use by hand (two checks a minute, every minute), plus a cap on how often any one website can be checked – that stops bots using XKey to flood other people's sites.
Do I need to give my email address?
No. XKey never asks for an email, an account or card details – not even for weekly monitoring, which gives you a private link instead.
Can I check a competitor's website?
Yes – any public website. To see your site and up to two competitors side by side, use the competitor comparison.
Why is my score different from other SEO checkers?
Each tool weights different checks. XKey gives extra weight to things that stop a page appearing at all (indexing, titles, H1) and adds AI search readiness, which most checkers don't measure yet.
