Adoption audits verify that publishers can extract full value from the platform. Whenever metadata or scripts prevent optimal operation, an audit fires so users can identify and fix what is missing. If an audit fails, use the metadata debugging tools to locate the root cause.

What do adoption audits check?
Adoption audits verify that all metadata and scripts required for optimal platform operation are present and correct. They cover structured data fields like author, title, canonicalUrl, publishTime, sections, and mainImage, as well as AMP analytics integration and Flowcards activation code.
How do I fix a metadata audit failure?
Each metadata audit identifies a specific structured data property that is missing, empty, or invalid. To resolve it, inform the corresponding structured data type (such as author, datePublished, image, or articleSection) in your article markup. Marfeel extracts metadata using sequential strategies including custom tagging, structured data, microdata, Open Graph, and RDFa. See how Marfeel extracts metadata for the full reference.
What is required for Flowcards to work on AMP pages?
Flowcards on AMP require four elements: the correct CSS rules in your AMP custom styles, the Flowcards HTML code placed before your page content with the correct attributes, the amp-script, amp-iframe, and amp-bind extensions in the head, and the latest Flowcards version hash. See the Flowcards AMP activation guide for detailed setup instructions.
