Write once, then play with a live desktop-to-mobile search-result scene. See where your title and description enter the local visibility boundary before you freeze a shareable draft.
Playable draft studio
Drag the viewport rail inside the scene or use the size control. Every edit stays a draft until you explicitly freeze it.
Draft is live. No artifact or Google claim has been released.
Drag the orange viewport handle · mouse wheel or arrow keys fine-tune · F opens Focus view
These files describe this local composition only. They are not proof of a Google result.

Everything runs in this browser. Head HTML is tokenized without execution and is capped at 64 KiB per side.
The approved or currently deployed metadata.
The metadata you intend to release.
BLOCK covers explicit defects such as noindex, invalid URLs or duplicate canonicals. INDETERMINATE preserves uncertainty for missing optional metadata, cross-origin canonical review, parser coverage or a local width boundary. BLOCK always wins.
JSON, formula-safe CSV, desktop/mobile SVG and PNG previews, review Markdown and Receipt v1 are generated from the same result. Only PASS creates copy-ready metadata; BLOCK and INDETERMINATE create a non-executable remediation plan. Every SHA-256 covers exact download bytes.
No URL is fetched and no pasted head is executed. Input persists only in this tab's session storage. Google may create title links and snippets from other sources, so PASS is not an appearance or performance guarantee.
