Search engines

  1. 1. Search Engines <ul><li>Going Beyond Google </li></ul>
  2. 2. Seek and you shall find….. <ul><li>Using a search engine is like asking somebody to look through all the libraries in the world for you- to find just about everything! </li></ul>
  3. 3. Google Google is one of the most popular search engines- it currently claims to have 8 billion web pages- That’s 8,000,000,000!
  4. 4. Has Google got everything covered ? <ul><li>Out of all the information on the World Wide Web, how much do you think can be found through using Google? </li></ul><ul><li>Have a guess- what percentage? </li></ul>
  5. 5. Amazingly, the answer is only somewhere between 2% and 5% <ul><li>This part not indexed is “the invisible web”. </li></ul><ul><li>So if you only ever search on Google- </li></ul><ul><li>that’s a lot of information out there that you might never find. </li></ul>
  6. 6. KEYWORD SEARCHERs <ul><li>use virtual robots,or spiders, to search the internet for keywords. They don’t “think” like you do-they just collect the pages where they found the keyword. </li></ul>
  7. 7. Sweetie Pie <ul><li>Remember the House of Sweets? A search engine would be like a robot that you sent to roam the building looking for your favourite chocolate bar. </li></ul>
  8. 8. Top Ranking! <ul><li>Google has a formula for ranking results- it won’t always be the best ones at the top! </li></ul><ul><li>Celebrities often pay experts to make sure the good things about them are listed first, like charity work. </li></ul>
  9. 9. Hard Sell <ul><li>Any Google search will bring up lots of sites that are trying to sell things- sites like Amazon and Ebay usually crop up. </li></ul><ul><li>This means you have to wade through lots of irrelevant results to find what you are searching for. </li></ul>
  10. 10. Go Beyond Google! <ul><li>Try these other keyword searchers- </li></ul><ul><li> </li></ul><ul><li>Try typing Mars and see what happens. Can you find some results for Mars other than the planet, the god and the chocolate bar? </li></ul><ul><li> </li></ul><ul><li>How quickly can you find out when the artist Van Gogh was born? </li></ul><ul><li> </li></ul><ul><li>How tall is the Eiffel Tower? </li></ul>
  11. 11. A very clever site….. <ul><li> </li></ul><ul><li>Gives you a list of “credible” or reliable results, and also a news section. Scroll down the results page and look at the different headings. </li></ul><ul><li>Try searching for War Horse, the book made into a play. Can you find out who is making it into a film? </li></ul>
  12. 12. The future is orange? <ul><li>Some search engines list similar-sounding topics so that you can quickly find the one you need. Try our old favourite, life on Mars, and look at Folders, then Circles, then Foam Tree. </li></ul><ul><li> </li></ul>
  13. 13. Get the Picture <ul><li>Search for images on these sites- </li></ul><ul><li> </li></ul><ul><li>http :// </li></ul><ul><li>Using these, can you find </li></ul><ul><li>The McDonalds logo? </li></ul><ul><li>A seaside pier on fire? </li></ul><ul><li>Anne Boleyn? </li></ul>
