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.
