Structured data should clarify visible Mars Market information, not add claims, dates or status labels that the page does not support.
Match names and descriptions
Use the same core page title, description and editorial purpose in markup and visible content.
Conflicting language can reduce trust and make crawler interpretation harder.
Use accurate dates
Update datePublished, dateModified and sitemap lastmod only when the associated content has changed.
Artificial freshness is unhelpful to both readers and search systems.
Validate after deployment
Check the deployed HTML, canonical URL and JSON-LD instead of assuming local source reflects the live page.
Live validation catches production-origin and rendering errors early.
