Searching the World Wide Web
World Wide Web
- There is a huge amount of information on the World Wide Web.
- Not all information is useful and some of it is wrong.
- You need to know how to search well to make sure the information is high quality.
Search engines
- Google, Bing, DuckDuckGo, and Ecosia are examples of search engines.
- Search engines work by searching for web pages.
- Searching for web pages is called ‘crawling’.
Searching for matching words
- When you type words into a search engine, the search engine looks for web pages.
- Then, the search engine shows you a list of pages that match your words.
Choosing the page you want
- The search engine ranks (puts in order) the pages based on:
- How closely your search matches the page.
- The popularity of the page.
- The page highest on the list may not be the best page for your search.
