Free SEO checker
Thirteen on-page checks in about 20 seconds, including the 2026 essentials most tools ignore: structured data for AI search, llms.txt and social sharing tags. One score, every issue explained.
Starting your check...
We load your page in a real browser, so JavaScript-rendered sites are measured correctly. We also probe your robots.txt, XML sitemap and llms.txt.
The fundamentals, plus what 2026 demands
Search changed. Google AI Overviews and assistants like ChatGPT now answer questions directly, and they choose their sources based on signals most websites have never optimised.
Classic on-page SEO
Title tags, meta descriptions, H1 structure, canonical tags, image alt text, content depth, sitemaps and robots.txt. The basics that still decide most rankings.
AI search readiness
Structured data and llms.txt tell AI assistants who you are and what you offer. Sites without them are increasingly invisible in AI answers.
AI visibility serviceA score you can act on
Every issue is weighted by real ranking impact and explained in plain English, so you know what to fix first and why it matters.
One page is a snapshot. The audit is the film.
This checks one page. Your site has many.
A single-page snapshot finds the obvious problems, but rankings are won site-wide: crawl issues, duplicate content, internal linking, page experience, content gaps against competitors and backlink quality. Our full SEO audit covers all of it, with a 90-day action plan ranked by impact, for a fixed £299.
- Full technical crawl of every page
- Keyword and content gaps against your real competitors
- Prioritised 90-day plan, yours to keep or have us deliver
Frequently asked questions
What does this SEO checker look at?
Thirteen weighted checks: page title, meta description, H1 structure, canonical tag, HTTPS, mobile viewport, image alt text, structured data, robots.txt, XML sitemap, llms.txt, content depth and Open Graph tags. Each one shows a pass or a clear explanation of what to fix.
What is llms.txt and why does it appear in my results?
llms.txt is an emerging standard file that tells AI assistants like ChatGPT what your site offers, similar to how robots.txt guides search crawlers. Very few sites have one yet, which is exactly why early adopters stand out in AI search results. We flag it as informational rather than counting it against your score.
Why does my page pass here but still not rank?
On-page health is necessary but not sufficient. Rankings also depend on content quality, competition, backlinks and site-wide technical health. If your on-page checks pass and rankings still disappoint, a full audit will usually find the reason within days.
Does the checker work on JavaScript sites?
Yes. We render pages in a real Chromium browser before checking, so React, Vue and other JavaScript-rendered sites are measured as Google actually sees them.
Is this really free with no email required?
Yes. Run as many sensible checks as you like. We rate-limit heavy automated use so the tool stays fast for everyone.
