What Does “View Source” Show You?
Every webpage you visit is built from HTML — a structured set of tags that tells the browser what to display and how to arrange it. When you view source code, you’re seeing the raw HTML the server sent to your browser before it was rendered into the visual page you see.
This includes the page’s meta tags (title, description, Open Graph data), heading structure, inline CSS styles, JavaScript references, schema markup, and all the text content in its original form. What it doesn’t show is JavaScript-rendered content — code that runs in the browser after the page loads. For that, you’d need browser developer tools.
What You Can Do With This Tool
Check meta tags — Instantly see the title tag, meta description, canonical URL, and Open Graph tags for any page. Useful for quick SEO audits without opening a browser or installing extensions.
Inspect heading structure — Search the source for <h1>, <h2>, and <h3> tags to verify a page’s heading hierarchy. Correct heading structure matters for both accessibility and SEO.
Find schema markup — Look for application/ld+json script blocks to check whether a page has structured data — and what type (Article, Product, FAQ, etc.).
Review third-party scripts — See which analytics tools, ad platforms, tracking pixels, and external scripts a page loads. Useful for competitive research or auditing your own tag implementation.
Check robots directives — Find the <meta name="robots"> tag to see whether a page is set to index or noindex, and whether links are followed or nofollowed.
Learn from real websites — Studying how well-built sites structure their HTML is one of the most effective ways to learn web development. This tool makes any public page’s code readable and accessible.
Why Not Just Use Ctrl+U in the Browser?
You can — but there are situations where this tool is more convenient. If you’re already in the middle of an SEO audit and don’t want to open a new tab and navigate to the page, entering a URL here is faster. It also gives you a clean, formatted view with line numbers and the ability to download the source as a file. For people learning HTML who aren’t comfortable with browser developer tools yet, a dedicated source viewer is less intimidating.
One important note: some websites block direct embedding or proxy access. If a URL returns a blank result or an error, the site is likely blocking third-party fetch requests. In that case, the browser’s built-in Ctrl+U (or Cmd+Option+U on Mac) will always work since it fetches directly from your browser.
Source Code vs Rendered HTML
The source code this tool fetches is the initial HTML delivered by the server — the same as pressing Ctrl+U in your browser. It does not execute JavaScript, so content loaded dynamically (like React or Vue apps, lazy-loaded sections, or content injected by JavaScript) won’t appear in the raw source.
If you need to inspect rendered HTML including JavaScript-generated content, use your browser’s Inspect Element (right-click → Inspect) rather than View Source. For SEO purposes, both matter — Googlebot renders JavaScript, but checking raw source is still useful for verifying static tags like meta and canonical.
