Google\’s Page Tool: Enter URL, Rendered HTML + DOM + Real H1–H2 Output

Tool: Enter URL → Break Down Site (SEO + UX + Technical)

It does not just score like a classic \”site audit / seo audit\”. This tool answers the following question on a single page: \”How does Google really see this page; what does the user see on the first screen?\”

Critical point on Google\’s side: Googlebot evaluates through rendered HTML, especially on JavaScript-heavy pages; just “view source” is not enough. 

1) What it does

• Page crawling / website crawler / single URL audit: Fetches the URL, reads the HTTP status and basic head signals.
• “How Googlebot sees / view as Googlebot” mode:
  • Produces rendered HTML / rendered source (DOM created after JS after) and displays it raw.
  • Focuses on producing view rendered page / view crawled page output similar to the logic of “Google Search Console URL Inspection” (screenshot + HTML).
• “Text only view / search engine simulator”: Simplifies the content that Google can “read” as text and links.
• Real heading structure: Extracts the H1–H2–H3 hierarchy through the rendered DOM with the logic of heading structure / heading tags test / heading outline (also captures H headings changed later by JS).
• UX “push-down” diagnosis (above the fold / first screen analysis): Marks areas that push the user down: large hero, sticky header, cookie banner, popup, ad blocks, etc. The concept of “above the fold” provides a clear framework at this point.
• Layout shift / CLS analysis: Marks areas that cause jumps on the first screen (cumulative layout shift) based on the DOM; compatible with Lighthouse\’s CLS approach.

2) Why “not a classic audit”

Classic technical SEO analysis reports usually provide a “list of findings + score”. Your goal is different:

• To show the difference between Google and the user starkly on a single URL.
• To create the shock of “The site I thought was different from what Google sees.” This difference particularly arises in issues like JS rendering, hidden content, incorrect canonical/noindex, H1 added/removed later in the DOM.

3) Input / Output

Input:

• Single URL (option: user agent selection: desktop/mobile; “googlebot rendering” simulation)

Output panels (clear and action-oriented):

1. Rendered Page Snapshot (user screen + Google-like render)
2. Rendered HTML / DOM tree (DOM analysis, node counts, critical elements)
3. Text Only + Link Map (text only view, internal link extraction)
4. Heading Structure Tree (H1 checker, headings checker; hierarchy errors)
5. SEO Head Signals (meta title check, meta description check, canonical check, robots meta tag check, hreflang check, noindex check)
6. Above the Fold / Below the Fold Blocks (list of areas pushing the user down)
7. CLS / LCP tips (core web vitals, lcp analysis, cls analysis; candidates for render-blocking resources)

4) How it marks “unnecessary areas pushing the user down”

The tool references the first screen (viewport) and captures:

• Hero area too large: Marks if H1 is disconnected from the content and the first screen is a “blank showcase”.
• Cookie banner analysis / popup analysis: Shows layers that overlap the content or occupy the first screen.
• Sticky header analysis / ad area analysis: Lists fixed blocks that push down the actual content start.
• Behaviors triggering layout shift: Captures areas that fall into CLS reasons like “avoid inserting new content above the fold”.

5) Best real-world usage scenarios

• The agency proving to the client “look, this is how Google sees it” (ends the debate).
• Capturing visibility issues caused by javascript seo in structures like SPA / React / Next.js (difference between rendered html vs source code).
• Even in projects without Search Console access, conducting “near reality” reviews (then verification with GSC URL Inspection).
• Speeding up the “rendered HTML” approach of tools like Screaming Frog to a single page (no setup, no crawl).

6) Clear promise (the “surprise” the user will experience)

• If content thought to be present in the DOM is absent: It does not appear in the naked text → It becomes clear that Google cannot take it as text.
• If what you think is H1 is actually H2 (or if JS changes it later): the heading structure panel shows this starkly.
• If the first screen is “occupied”: the above the fold panel lists areas pushing the user down item by item.
