Covered

Assisted

Proposed with the evidence. A person confirms it.

Why it matters

Google's guidelines say not to mark up content that readers cannot see, even if it is accurate. Irrelevant structured data can be treated as abusive: filters make it ineffective, and egregious cases lead to a manual action that removes rich result eligibility without affecting web ranking. Google said at Search Central Live that once it sees markup it does not trust from a site, it may stop using that site's structured data altogether.

How to meet it

Generate markup from the same fields that render the visible content, use it for the machine-precise form of visible facts (an ISO date for a shown date, the homepage url for a named organisation), and remove markup for content a page no longer shows.

How to test it

For each template, the Rich Results Test output matches what the page visibly shows, and the Manual actions report in Search Console is empty.

How Regensbot covers it

AssistedNeedsYour verified site

Regensbot proposes a verdict with the evidence; a person on your team confirms it.

The evidence comes from your verified site: its pages, its profile and the files you upload.

You verify the site by a DNS TXT record, a meta tag or a file. Regensbot then keeps a checklist item for this requirement, with a state, a guide, an evidence upload and reminders.
