How To
Use the SEO Audit to see what Google and social bots read on your pages. Paste a URL or HTML, preview how your content appears on major platforms and get actionable tips to improve visibility.
How can I check a web page's SEO?
Use the free SEO audit from Cogitans: paste your page's HTML or enter its URL to find missing or inconsistent tags. Check the title, description and other tags flagged as missing or inconsistent. If fetching the URL fails, use HTML mode. Analysis reads the supplied HTML. URL mode fetches the remote document through a proxy. The tool inspects that document without running its JavaScript. Paste <html lang="en"><head><meta name="description" content="Demo page"><link rel="canonical" href="/unknown/"></head><body>Example</body></html>. The audit finds a missing title, reads the description and detects a relative canonical. Visit a destination separately to check its HTTP response.
Why does my link have no image when I share it?
A missing or incorrect image tag is one possible cause. Paste your page's HTML into the Cogitans SEO audit to examine the title, description and image declared for sharing. Flagged Open Graph tags show what to inspect in your site. The tool's previews are simulations, so also check the result on the platform where you share the link.
How can I analyse a page the tool cannot load?
Copy its HTML and paste it into the HTML tab. This mode analyses the document you provide without asking the remote service to fetch the page. Referenced images may load for previews.
Does this audit explain why my site ranks poorly on Google?
This audit examines HTML tags. It cannot fully explain a ranking: it does not measure Google positions, actual indexing or inbound links. A site may block the proxy or serve different HTML to different visitors. Previews are simulations and cannot guarantee what a search engine displays.
