Why Run an SEO Audit?

Every website has hidden SEO issues costing it traffic. A broken canonical tag, a missing meta description, an image without alt text — small problems that search engines notice even when you don't. Our free SEO audit tool finds them in seconds so you can fix what matters and stop losing rankings to competitors.

Google uses over 200 ranking factors, and its Core Web Vitals update made page speed a direct ranking signal. Google's Helpful Content System also evaluates whether your pages demonstrate genuine human expertise — and with AI-generated content flooding the web, having a built-in AI content detector in your SEO audit is no longer optional. An SEO site audit is the fastest way to identify which factors are working against you — and which ones you can fix today.

🔧

Find Technical Errors

Catch crawl issues, broken links, slow pages, missing sitemaps, and HTTPS problems that stop Google from indexing your site.

📈

Improve Your Rankings

Fix the issues Google penalises — missing title tags, duplicate content, poor mobile usability, slow Core Web Vitals.

🤖

Detect AI Content

Our built-in AI content detector scans your page text for AI writing patterns — sentence uniformity, burstiness, vocabulary diversity, and transition word overuse. Know your AI score before Google does.

How often? Run a full website SEO audit monthly, or immediately after any major site change — redesign, migration, CMS update, or new content strategy.

Frequently Asked Questions

What is a free SEO audit tool?
A free SEO audit tool automatically analyses a website and identifies SEO issues without charging a fee. It checks technical factors (crawlability, speed, HTTPS), on-page elements (title tags, meta descriptions, H-tags), content quality, and more — providing a prioritised list of issues to fix.
What is a site audit vs a website audit?
They refer to the same process. "Site audit" typically focuses on technical SEO checks, while "website audit" can also include UX, content, and accessibility. Our tool covers all of these in one scan.
How do I do a free SEO audit?
Enter your URL in the tool above and click "Run Audit." The tool checks 60+ SEO factors in seconds and generates a prioritised report you can download as a PDF or export as CSV — completely free, no signup required.
How often should I audit my website for SEO?
Run a full audit at least every 3–6 months, and immediately after any major change — redesign, migration, new content strategy, or CMS update. Monthly mini-checks using Google Search Console are also recommended.
What does a technical SEO audit check?
A technical SEO audit checks: crawlability, indexation status, page speed, Core Web Vitals (LCP, CLS, TBT), HTTPS, XML sitemap, robots.txt, canonical tags, mobile usability, structured data, and redirect chains.
Can I audit my eCommerce site with this tool?
Yes. The tool checks eCommerce-specific issues including product page optimisation, duplicate content from URL parameters and filters, schema markup for products and reviews, and page speed.
What does an SEO audit report include?
Your report includes: an overall SEO score, issues categorised by severity (Critical / Warning / Passed), specific fix recommendations, Core Web Vitals data, AI readiness score, and exportable PDF and CSV formats.
Is a free SEO audit as good as a paid one?
Our free automated audit catches the same technical and on-page issues a paid tool would. The difference is that a paid agency audit also includes strategic interpretation, competitor analysis, and a custom action plan — value that requires human expertise.
What is a white label SEO audit?
A white label SEO audit lets agencies brand the report with their own company name before delivering it to clients. Our tool supports this — enter your company name in the form and it appears on the generated PDF report.
How long does an SEO audit take?
Our automated tool produces results in under 60 seconds for most sites. A manual agency audit takes 1–3 weeks. For large enterprise sites (100,000+ pages), a full crawl-based audit may take several hours.
Does this tool include an AI content detector?
Yes. Our SEO audit tool includes a built-in AI content detector that automatically analyses the page text during the audit. It checks 6 statistical signals — sentence uniformity, burstiness, vocabulary diversity (TTR), transition word density, opening patterns, and 3-gram phrase repetition — and produces an AI probability score from 0–100%. This helps you identify pages that may be flagged by Google's Helpful Content System for lacking human expertise. No separate tool or text pasting needed — it works directly on the URL you audit.
How accurate is the AI content detection?
Our AI content detector uses statistical heuristic analysis — not a machine learning classifier. It analyses writing patterns like sentence uniformity, burstiness, and vocabulary diversity that differ between AI and human writing. No AI detector is 100% accurate. Formal, technical, or heavily templated human writing may produce false positives. Use the AI score as one signal among many — not as a definitive verdict. The detailed 6-signal breakdown helps you understand exactly which patterns triggered the score.
