Google Search Console Pitfalls & Critical Warnings
Avoid these 3 common validation traps, parser errors, and algorithmic policy penalties when deploying QAPage schema.
Marking Up Multiple Questions on Single QAPage (Must be FAQPage)
Using QAPage schema on pages that list multiple distinct questions (Google QAPage requires exactly ONE primary question).
Use QAPage strictly for single thread pages. For pages with multiple Q&As, use FAQPage.
Missing acceptedAnswer or suggestedAnswer upvoteCount
Omitting the upvoteCount integer on community answers.
Always include upvoteCount on Question and all Answer entities.
Marking Answers as Accepted Without Community Verification
Hardcoding editorial answers as acceptedAnswer on unvetted marketing pages.
Reserve acceptedAnswer for genuine user-accepted solutions in discussion boards.
