Frequently Asked Questions
How long does it take for rich snippets to appear?
Rich snippets can appear anywhere from a few days to several weeks after implementing valid schema markup. Google needs to crawl, index, and process your structured data before displaying rich results.
Can I use multiple schema types on one page?
Yes, you can include multiple schema types on a single page using separate JSON-LD script blocks or by nesting related schemas within a parent schema object when appropriate.
What's the difference between JSON-LD and microdata?
JSON-LD is Google's preferred format because it separates structured data from HTML content, making it easier to manage and less prone to errors. Microdata embeds markup directly in HTML attributes.
Why isn't my schema markup showing rich results?
Common reasons include validation errors, missing required properties, content-markup mismatches, low page authority, or Google simply choosing not to display rich results for that query.
