Crew Gray have been learning all about web crawlers today and how search engines create index pages of all of the websites using web crawlers and hyperlinks. We explored how web crawlers work using non-fiction books to find information from the index and contents pages, and realised that this can take a long time for a human to complete, especially if you have to look through more than one book to find the correct information. We then looked further into how Google uses web crawlers and found that these are not actual people, so can get the job done much faster! After that, we became web crawlers around the classroom and rated our classroom objects using a table. We included the quantity of the object, the quality and the distance from where we were. These numbers then totalled up and we were able to rank the resources from highest to lowest. From this, we were able to see how search engines rank different websites using the quantity of times a key word is used and the quality of the information on the page, and how this affects the order that websites appear within search engines.
