The page that appears when you input a query into Google, Yahoo, or another search engine is a search engine results page or SERP. 

The SERP layout varies depending on the search engine, but as Google dominates the market with over 80% of the searches, we’ll concentrate on their features and algorithms. Different SERP features will appear following a search depending on the type of query input. 

The three types of search queries that are most frequently used are transactional, informative, and navigational. The SERP of today has more visual variety than it had in the past. Searches can also provide results that include photos, shopping recommendations, Tweets, or information cards, in addition to immediate results that only show the site name and metadata.
