o, featured snippets and structured data are not the same thing. In simple words, featured snippets are a portion of text that Google determines from relevant and any random website, and it appears at the top of a Google search result page.
Also, the system determines the length and the choice of a paragraph that will be picked from a relevant web page based on the search query.
On the other hand, structured data is a standard format that Google or search engines use to provide information about the page. It makes the search results more engaging and gives users an overall outline of the page.
For instance, on a recipe page, the structured data will also focus on the ingredients, cooking time, temperature, calories, and so on.
This leads to what Google terms ‘rich results’ encouraging users to interact with your website.
