Schema Implementation FAQ

1. What is the main benefit of this tool?

It provides a direct view of the data search engines see, allowing you to catch errors before they affect your rankings.

2. Does this tool detect Microdata?

This version focuses on JSON-LD, which is the modern standard recommended by Google for its efficiency and ease of use.

3. Why are my results showing as "Type"?

This occurs if the '@type' field is missing in your code. Ensure every block has a defined category like Article or Product.

4. How many schema blocks can a page have?

There is no limit. You can include Breadcrumbs, Articles, and Reviews on the same page to provide full context.

5. Is this check real-time?

Yes. By using no-cache logic and server-side fetching, we pull the most recent version of your live code.

6. Can I use this for local business SEO?

Absolutely. It is perfect for verifying LocalBusiness schemas including address, telephone, and coordinates.

7. Why do I get a "Could not reach site" error?

Some sites block automated requests. If the site is live but failing here, it likely has a firewall preventing external fetching.

8. Does valid code guarantee a rich snippet?

Validity is required, but Google also evaluates the relevance and quality of the content before displaying snippets.

9. What is the difference between JSON-LD and Schema?

Schema.org is the "vocabulary" or language, while JSON-LD is the "format" used to write that language.

10. Can I copy the code for my own site?

Yes. If you see a markup you like on another site, use our "Copy" button to get the structure and adapt it for yourself.

11. Is my search history saved?

No. ToolHost respects your privacy; all checks are processed in the current session and never stored.
