SERPs include links to different webpages that are relevant to the user's query, along with additional information or images. Many SERPs contain paid ads at the top, followed by organic results underneath. However, the SERP for one keyword can look a lot different from the SERP for another.

A SERP feature is any result on a Google Search Engine Results Page (SERP) that is not a traditional organic result. The most common SERP Features are: Rich Snippets which add a visual layer to an existing result (e.g., review stars for product ratings)

SERP features are unique results on Google's search engine results pages (SERPs) outside of traditional organic listings, including elements like Rich Snippets, review stars, featured snippets, the People Also Ask component, and knowledge panels.

Basically, the SERP consists of three types of search results: organic results, paid results, and rich results enhanced with different features, such as images, videos, rating stars, etc.
