Let’s begin by exploring what search engines are, why they exist, and how they make money.
What are search engines?
Search engines are searchable databases of web content. They’re made up of two main parts:
- Search index. A digital library of information about webpages.
- Search algorithm(s). Computer program(s) tasked with matching results from the search index.
What is the aim of search engines?
Every search engine aims to provide the best, most relevant results for users. That’s partly how they gain market share.
