What is the Website SEO Audit?
Enter any URL to get an instant, in-depth SEO audit of the live page. The checker fetches the page like a search engine crawler and tests more than 60 factors: indexability, HTTPS, redirects, robots.txt, XML sitemap, title and meta description, headings, content depth, images, internal links, structured data, Open Graph, mobile setup, server response and compression.
Add a target keyword to see how well the page is optimised for it, run a Google PageSpeed test for Core Web Vitals, and check AI search readiness — the signals that help ChatGPT, Gemini and Google AI Overviews understand and quote your content. Every issue comes with a plain-English fix.

What an SEO audit checks and why
Search engines must be able to crawl a page, index it and understand it before they can rank it. Technical checks (status code, robots rules, canonical, sitemap, HTTPS) make sure nothing blocks crawling and indexing. On-page checks (title, headings, content, links, images, schema) make sure the page clearly signals what it is about and deserves to rank. Performance checks make sure the experience is fast enough to satisfy visitors and Google’s page experience signals.
How to read your SEO score
The score weights each check by its impact. A missing title or a noindex tag costs far more than a missing Twitter card. A score above 85 means the fundamentals are in good shape; between 60 and 85 there are meaningful improvements to make; below 60 there are issues likely to hold rankings back. The score measures on-page health, not authority — backlinks and competition still decide who ranks first.
Optimising for AI search
AI assistants and Google AI Overviews prefer content they can confidently extract: clear question-and-answer sections, concise definitions, lists, tables, named authors, up-to-date dates and accurate structured data. The AI readiness checks highlight quick wins that also improve traditional featured snippets.
Pro tips from our PPC and SEO team
- Fix indexability problems before anything else.
- Write a unique title and meta description for every page.
- Use one H1 and descriptive H2s that match the questions people ask.
- Compress images and set width and height to avoid layout shift.
- Re-run the audit after every major update to the page.
Website SEO Audit: frequently asked questions
Is this SEO audit tool really free?
Yes. There is no sign-up, no credit card and no limit beyond a fair-use rate limit that prevents abuse.
Does it crawl my whole website?
It audits the page you enter in depth, plus site-wide files such as robots.txt, the XML sitemap and llms.txt. Audit your most important pages one by one — homepage, top services and best-selling products.
Why does my score differ from other SEO tools?
Every tool weights factors differently. Focus on the individual issues rather than the number; fixing the failed checks will improve visibility regardless of tool.
What are Core Web Vitals?
They are Google’s user-experience metrics: Largest Contentful Paint (loading), Interaction to Next Paint (responsiveness) and Cumulative Layout Shift (visual stability). They are part of Google’s page experience signals.
Can it audit pages that block bots?
If a firewall or security plugin blocks automated requests, the audit may fail or see a challenge page. Whitelist the tool temporarily or test a different page.
Does a perfect score guarantee first-page rankings?
No. On-page SEO is necessary but not sufficient. Rankings also depend on content quality, search intent, backlinks, brand signals and competition.
