A search engine is a way to find information on the Internet. Just like you would use a library catalog to find books, or Google to find websites, you can use a search engine to find information.
There are many different types of search engines, but they all work in similar ways. You type in what you are looking for (a “keyword”) and the search engine looks through all of the websites it has indexed to try and find websites that match your keyword.
The results will usually be displayed in order of how relevant the website is to your keyword. This is why it is important to choose keywords carefully – if you use too general of a keyword, you will get lots of results that are not very useful. If you use too specific of a keyword, you might not get any results at all.
Some popular search engines are Google, Yahoo, and Bing. There are also many specialized search engines, like Dogpile (which searches other search engines), or Education World (which is an education-focused search engine).
How do you use a search engine? Let’s say you want to find out more about the history of the United States. You would go to your preferred search engine and type in “United States history” as your keyword. The results will bring up websites about different aspects of U.S. history – from the Revolutionary War to the present day.
