Does structured data effects SEO? I mean they effect SERP CTR but does have any effect on SEO too?

Structured data is essential for search engine optimization since it makes it simpler for search engines like Google to comprehend the topic of your pages, items, and overall website. Before displaying a page in the search results, Google must first determine what the page is about. When you use structured data on your website, you are essentially having a conversation with Google and telling it about the content of your site.
