There are basically 4 types of components in the SERP, which are
- The search query contained within a query box – this is the word, or set of words that the user is searching for
- The organic results – Organic SERP listings are the natural listings generated by search engines based on a series of metrics that determines their relevance to the searched term. Getting your page listed here, on page one of the SERP is the what SEO is all about
- Paid Results – every search engine with market share accepts paid listing, also known as Pay Per Clicks (PPC). These Paid results are bought by bidding on Keywords (e.g AdWords)
- Universal Results – in addition to organic results (e.g., image results, new results, featured snippets)
- Knowledge Graph – Definite information presented in an info box to the right of the search results
A Google SERP Page can also contain SERP Features such as Rich Results (previously described as Featured Snippet) To get a rich result, the page must contain structured data markup
