AMP HTML · source validator companion

Check AMP source before official validation

Paste AMP HTML and review required markup, runtime setup, boilerplate, canonical and viewport tags, component extension scripts, custom CSS size, prohibited elements, and metadata cues without pretending to be Google’s validator.

AMP SOURCE

Paste the HTML you plan to validate or publish

The checker reads only supplied source. It does not fetch URLs, run the AMP runtime, or validate linked component files.

Boundary: this is a fast source review, not the official AMP validator, browser renderer, Google Search test, or cache-acceptance proof.

AMP

Ready for AMP source.

No sample validation result, official AMP pass, Google cache result, rich-result promise, ranking impact, traffic claim, or manufactured AMP score appears before you paste source.

AMP WORKFLOW

Use this as the source pass before the official validator

Start with required markup

AMP documents need explicit boilerplate, runtime, canonical, charset, viewport, head, body, and AMP declaration before component-specific checks matter.

Replace unsupported HTML

Common HTML elements such as img, iframe, video, and custom scripts need AMP-supported components or markup patterns.

Validate with the platform

After source review, run the official AMP validator and any Search Console tests required by your publishing workflow.
