Page Source Viewer

A page source viewer fetches a URL and shows the raw HTML our server receives before any JavaScript runs, plus the status code, final URL, content type and size. It helps you see what a basic crawler reads first.

This tool fetches the address you enter once, from our server, and reports what a crawler would receive. The URL is not stored; only a short-lived rate-limit counter is kept. Results show the page at the moment of the check and can differ from what a logged-in browser or a bot with different headers sees.

How to read the result and act on it

Check the status and final URL first, so you know which page you are reading. Then search the source for your title, main heading, canonical tag, structured data and key internal links. If your main content or links are missing here but visible in the browser, they rely on JavaScript, which can delay or limit indexing. Use the copy button to paste the source into an editor for searching. Compare the result with the URL Inspection tool in Search Console for the rendered view.

Common mistakes to avoid

The common mistake is assuming what you see in the browser is what a crawler gets. Another is reading a cached or different version: our server sends a plain bot-style request, so pages that vary by location, login or user agent can differ. Do not paste secrets from source into public places, and remember the output is truncated for very large pages.

What is the difference between page source and the rendered page?

Source is the HTML the server sends. The rendered page is what the browser builds after running JavaScript, which can add or change content.

Why check raw HTML for SEO?

Search engines read raw HTML first. Important content, links and tags should be present there, not only added later by scripts.

How do I view source in a browser?

Use view-source: before the address, or the keyboard shortcut for View Source. Developer tools show the rendered DOM instead.

• Raw HTML Content Checker: See what content exists in the raw server HTML before JavaScript runs.
• Meta Tags Analyzer: Fetch a page and list every title, meta and link tag in its head, with problems flagged.
• HTTP Header Checker: View the response headers of a URL: status, server, cache, content type and more.
