Pre-rendering (Fetch & Render)

Render a page with a real headless browser to see what a JavaScript-executing crawler sees: the post-render HTML and a screenshot, plus what changed versus the raw server HTML.

Render a page

We load the URL in headless Chromium with the user-agent you pick, then compare it to the raw HTML.

Why rendered HTML matters

Google renders, but not instantly

Googlebot crawls the raw HTML first, then queues the page for rendering. Content that only appears after JavaScript can be indexed late, or missed if rendering fails. Seeing both views shows the gap.

Many crawlers do not render at all

Plenty of bots, including some AI crawlers and social previewers, read only the raw HTML. If your links, copy, or metadata are injected by JavaScript, those crawlers never see them.

Check the important elements

Compare the <title>, headings, body copy, and internal links between raw and rendered. Anything that appears only after render is content you are relying on Google to execute.

Fix it at the source

Server-side rendering or static pre-rendering puts the important content in the raw HTML for every crawler. StudioHawk helps teams choose and ship the right rendering strategy.

Rendering uses headless Chromium for a single page on request. Results are provided for guidance only.

Is JavaScript hiding your content from crawlers?
