Overview of the Web Hundreds of millions of sites- Billions of pages Browsers –Firefox, Chrome, Safari, IE etc Search Engines such as Google – use Spiders and Crawlers to extract data Indexed and Stored in the Search Engine database You search the database -not the web.

Search engines Use a search engine when you have a clear idea what you are looking for on a specific subject. Use more search terms and more specific terms to give you more specific results. Search engines usually link your search terms with AND (i.e. search for all terms). Use quote marks to search for a specific phrase (e.g. “climate change”).
