✅ Troubleshooting and repair suggestion process

🧩 Tip: Do not step on common misconceptions

• ❌ Mark all pages as Articles when they are actually product pages

• ❌ FAQ schema was placed on the content page, but the page did not display the Q&A

• ❌ Wrap field values with HTML tags in Schema tags

• ❌ Using Microdata in JavaScript rendering pages (recommended to use JSON-LD)

✉️ summarize

Structured data is a powerful tool for enhancing SEO effectiveness, but improper use can be recognized by search engines as cheating and even affect rankings. Regularly use structured detection tools to troubleshoot and ensure:

1. Complete fields

2. Formats Specifications

3. True and consistent

4. Do not duplicate tags

If you are willing, I can check the structured data of a webpage for you or generate compliant structured JSON-LD tags. Just tell me the page content or URL.
