Google Search Console Pitfalls & Critical Warnings
Avoid these 3 common validation traps, parser errors, and algorithmic policy penalties when deploying DataFeed schema.
Stale dateModified on Dynamic Feeds
Leaving an old static dateModified timestamp on feeds that update hourly.
Synchronize dateModified with live cache invalidation timestamps.
Invalid MIME Type in encodingFormat
Using informal 'json' or 'xml' instead of official IANA MIME types.
Use 'application/json' or 'application/xml'.
Missing dataFeedElement Items
Outputting an empty feed header without demonstrating feed items.
Include sample DataFeedItem objects.
