Rich results may not appear immediately even if schema is correctly added. Common reasons include:

1. Google hasn’t crawled the page yet – Use Google Search Console → URL Inspection → Request Indexing.
2. Missing required schema fields – Ensure properties like name, image, price, availability, and ratings are present.
3. Page not eligible for rich results – The page content must match the schema type (e.g., product pages for Product schema).
4. New website – New sites may take time before Google shows rich results.
5. Duplicate schema – Multiple schema sources can cause conflicts.
6. Not guaranteed – Schema only makes pages eligible; Google decides whether to show rich results.
