Search engine
Web Search engines are a type of web site found on the World Wide Web (www). Information and websites can be found on the World Wide Web in 2 different ways:
- type in a web address in a web browser address bar
- If you know the web address of the website you can use this way
- search for keywords using a search engine
- If you do not know the website web address or if you don't know which website to look on
To use a search engine you must enter at least one keyword in to the search box. Usually an on-screen button must be clicked on to submit the search.
The Search engine looks for matches between the keyword(s) entered and its database of websites and words.
Quickly after a search is submitted the results appear on screen. This is called a search engine results page (SERP). The SERP is a list of webpages that contain matches to the keywords that were searched. The SERP usually shows web pages names, short descriptions and a link for each matching web page. The user can click on any of the links to go to one of the websites.
Search engines are some of the most advanced websites on the web. They use special computer code to sort the web pages on SERPs. The most popular or highest quality web pages will be near the top or the list.
When a user type words into the search engine, it looks for web pages with those words. There could be thousands, or even millions, of web pages with those words. So, the search engine helps users by putting the web pages it thinks the user wants first.
Search engines are very useful to find information about anything quickly and easily. Using more keywords or different keywords improves the results of searches.
Some examples of search engines are:
- Google (has the largest number of users in the United States)

- Forestle (helps the environment)
- Ask.com
- Bing
- Bluve
