The Science Behind Search #infographic

Published by Web Desk Tuesday, December 23, 2014

The University of Southern California’s library and information science department (librarysciencedegree) gives us this infographic on Google. In May 2014, Google was 68% of the search engine market in the United States; that number has been on the rise since Google was created. In 2000, there were 60+ million daily searches compared to the near 6 billion in 2013. Libraries aren't just for books anymore. Nowadays people go to the library just to get internet connection. For those that don’t have computers or the internet at home, 56% say that libraries are very important to them. Six steps to how search engines work:

1. Spiders (software) search for documents and web pages.
2. Spiders analyze each page.
3. Documents and pages are sent to the search engine’s indexing software.
4. This software takes the info from these sources and puts them in a database.
5. The user searches using the search engine query box.
6. Database searches for matching info, the most relevant pages (according to the spiders) are shown first.
7. The user gets a list of matching results with info about each page and links to pages
