Free technical SEO audit
Instantly audit your website’s <head> section for SEO, indexing, structured data, and metadata gaps.
Frequently asked questions
What is technical search engine optimisation?
Technical SEO is the practice of optimising a website’s infrastructure so search engines can efficiently crawl, index, and understand your content. It focuses on how your site is built rather than what’s on the page. The audit evaluates SEO-critical signals that influence indexing, interpretation by search engines, and visibility in both traditional and generative search results.
What is website crawlability?
Website crawlability ensures search engine bots can access your pages. It involves optimising your robots.txt file, XML sitemaps, and URL structure.
What is indexing?
Indexing makes sure search engines store your pages correctly in their index — preventing accidental “noindex” tags or duplicate content issues.
What is site speed & performance?
Faster sites rank better and reduce bounce rates. This involves image compression, caching, minimising CSS/JS, and using CDNs.
What is mobile optimisation?
Google uses mobile-first indexing, so this ensures the site works smoothly on mobile devices.
What is security?
HTTPS encryption is a ranking factor and prevents browser warnings that hurt trust and traffic.
What is structured data (schema markup)?
Structured data helps search engines understand content more clearly and enables rich results, such as star ratings, FAQs, and recipes.
What is site architecture?
A clean, logical structure improves crawling and UX, including internal linking and the use of breadcrumbs.
What is canonicalisation?
Canonicalisation prevents duplicate content by telling Google which version of a page to index.
Who should use this tool?
This tool is especially useful for SEO professionals auditing technical fundamentals, developers optimising semantic and head-level markup, agencies performing fast pre-audit reviews, content teams improving SERP and social appearance, and site owners looking for clear, actionable fixes without complexity.
What does this tool analyse?
This tool only analyses the contents of the <head> section of a publicly accessible webpage, focusing on SEO-critical signals that influence indexing, interpretation by search engines, and visibility in both traditional and generative search results. Areas analysed include meta titles and meta descriptions, indexing and canonicalisation, structured data and entity definitions, and social metadata and international targeting signals.
What does this tool not analyse?
This tool intentionally avoids areas outside the <head> to keep results precise and actionable. It does not analyse page body content or layout, footer or navigation elements, JavaScript execution or rendered DOM, performance, Core Web Vitals, or security headers, or rankings, backlinks, traffic, or analytics data.
Does this tool make changes to my website?
No. This tool only analyses your header and provides recommendations. It does not modify or inject any code.
What are the usage limits?
To ensure fair access and reliable performance, the tool may pause during periods of high traffic, the page must be publicly accessible on the web, and it must contain a proper <head> tag. If a page can’t be fetched or doesn’t include a valid head element, you’ll see a clear error message explaining the issue.
Why is my header not detected?
The audit requires direct access to raw HTML. Common causes include the page not being publicly accessible, the server blocking non-browser user agents, a WAF, bot-detection system, or rate limiter blocking the request, the page requiring authentication, cookies, or a session, or the server returning incomplete HTML. If the page can’t be fetched or parsed, the tool displays a clear error message explaining why.
Is my data stored or logged?
No content is stored long-term. URLs are processed temporarily to generate the analysis and then discarded.
Which AI model is used for analysis?
This tool uses GPT-5-nano.
Can I analyse private or staging websites?
If the page is publicly accessible, then the tool should work.
