CONTENT_FRESHNESS_UNKNOWN
Content freshness is unknown
No automatic fix — this needs a manual change on your siteWhat this check looks at
Whether any JSON-LD on the site declares `dateModified` or `datePublished`. Only checked once the site has some JSON-LD at all — a site with none is already flagged by JSON_LD_MISSING. Deliberately does not look at HTTP Last-Modified headers, which are an unreliable freshness signal in practice.
Why AI answer engines care
Without a dated JSON-LD signal, an AI assistant has no way to judge how current the content is and has to treat it as unknown rather than confidently recent.
Does Synviber fix it for me?
Not currently — this one needs a manual change on your own site or infrastructure; Synviber can detect it but does not publish an automatic fix for it today.
How to fix it manually
Low severity
Scanner message: "JSON-LD does not declare dateModified/datePublished, so AI assistants have no signal for how current this content is"
Add a `dateModified` (or `datePublished`) field with the real last-edited date to your JSON-LD, so AI assistants can judge content freshness instead of treating it as unknown.
