Search Engines

These programs search through the information on websites around the world looking for the keyword/s you have entered.

Keywords

These should be very specific.
If you use the word koalas but the site talks about a koala it won't find the word koalas.

Headings and blurbs

Each site has a heading and a blurb which may give an indication of what information it contains.

'Google' is widely recognised as a very efficient search engine because it searches through other search engines.

It also does clever searching like finding all of your words in the same document. However knowing how to use QUOTATION MARKS to keep words together can be useful.

If you want a definition or description try:

infoplease

britannica

encarta online

Question:

Keywords:

Does the heading, blurb or address help?
