AI‑Ready Demo Metadata Checklist: 12 Structured Data & Snippet Fixes That Make Playables Answerable

Search assistants and agent tools increasingly rely on schema.org JSON‑LD to extract canonical facts about pages and interactive experiences. If a demo is only visible inside an iframe, WebAssembly bundle, or behind a payment modal, agents can’t answer user queries nor generate safe snippets. Marking key facts — what the demo does, who made it, demo inputs and limits — lets agents answer correctly without crawling or rendering the interactive itself.

Agents prefer canonical fields (name, description, image, mainEntity, offers, and author) and special types like SoftwareApplication, HowTo and ImageObject. Properly chosen properties make it explicit which parts are public (demo preview) and which are gated (full product).

Below are the 12 checks to run on every playable or demo landing page. Each item includes the minimal rationale so you can prioritize what to ship first.

1) Add a top‑level SoftwareApplication block with clear public demo URL and offers. Why: signals to agents this page describes an app/playable and supplies canonical demo/offer metadata.

2) Expose an ImageObject for the demo preview with contentUrl and license. Why: thumbnails are often used in snippets and voice responses; ImageObject gives explicit licensing and attribution.

3) Add a HowTo (microdemo steps) for short playable flows (3–5 steps). Why: agents can read steps to answer “how do I try this?” without running the demo. Keep steps public and brief to avoid leaking paid steps. 4) Use offers with availability: 'InStock' vs 'OnlineOnly' and a clear priceCurrency. Why: helps snippets answer pricing queries correctly. 5) Map interactive controls with property 'featureList' or 'softwareFeature' inside SoftwareApplication to describe inputs and limits. Why: agents can summarize capabilities. 6) Use ClaimReview for any bold claims (benchmarks, accuracy) and link to sources. Why: enables safe assistant replies about claims. 7) Publish license and acquireLicensePage inside ImageObject and SoftwareApplication where relevant. Why: reduces follow‑up license questions. 8) Mark gated parts explicitly: use mainEntity to describe public page and add a CreativeWork with isAccessibleForFree=false for gated resources. Why: prevents agents from assuming gated content is public. 9) Include aggregateRating only if truthful and current; otherwise omit. Why: false ratings generate misleading snippets. 10) Expose a short FAQ (FAQPage) about demo limits and data handling. Why: agents often pull FAQ answers for snippet responses. 11) Set correct canonical and robots meta; use nosnippet only on pages where you want to block snippets. Why: prevents accidental snippet leakage of paywalled text. 12) Validate JSON‑LD with Google’s Rich Results Test and a schema validator before publishing. Why: malformed JSON‑LD is ignored by parsers and agents may fall back to rendering the page.

Below are compact, editable JSON‑LD blocks you can paste into your <head>. Replace placeholder values and keep gated fields out of public blocks.

SoftwareApplication (minimal, points to public demo):

{"@context":"https://schema.org","@type":"SoftwareApplication","name":"DemoApp — Live Microdemo","url":"https://example.com/demo","description":"Interactive 60‑second microdemo showing feature X","image":{"@type":"ImageObject","contentUrl":"https://example.com/demo-thumb.jpg","license":"https://example.com/license"},"offers":{"@type":"Offer","url":"https://example.com/pricing","priceCurrency":"USD","price":"0.00","availability":"https://schema.org/InStock"},"softwareVersion":"1.0.0"}

HowTo (3‑step microdemo flow — public preview):

Make gated content explicit with isAccessibleForFree:false and a separate CreativeWork or WebPage describing the gated asset. Example pattern: have a public SoftwareApplication block for the demo and a separate CreativeWork (isAccessibleForFree:false) with only summary metadata about the gated resource. This tells agents: the page documents functionality, full asset requires payment or login.

For claims (performance, benchmark numbers) use ClaimReview when possible and link to reproducible tests. If you can’t publish raw data, state that results are based on internal tests and provide a reproducible methodology link (not raw paid data). This reduces assistants inventing details or treating claims as verified facts.

bullets':['Use isAccessibleForFree:false on gated CreativeWork entries.','Keep public demo HowTo and image data in separate JSON‑LD blocks.','Use ClaimReview for extraordinary claims and link to methods.'],

Validation and monitoring: run JSON‑LD through the Rich Results Test and an open schema validator. Then simulate common assistant queries (“What does DemoApp do?”, “How do I try the demo?”, “Is it free?”) and confirm agents extract accurate answers. If you use A/B deploys, ship the metadata change first (it’s low risk) and observe snippet changes over days. Pages often require a re‑crawl to update agent caches.

Operational notes: keep a short public FAQ (FAQPage schema) about data usage, privacy and trial limits. If you must block snippets entirely for some pages, use the nosnippet meta tag, but prefer explicit structured markers (isAccessibleForFree) so assistants can still present accurate, non‑leaky summaries.

bullets':['Validate JSON‑LD with Google Rich Results Test and an independent schema validator.','Run manual assistant queries to verify outputs.','Ship metadata updates before major UI gating changes.'],
