Google has grown well beyond its search engine origins, but this is still the thing that it is best known for by the general public
. But, even if youâ€™ve performed countless searches, chances are you donâ€™t really know
whatâ€™s going on behind the scenes. When you ask Google to perform a search, it scours all of the publicly accessible online documents and then builds a search results page from the matches. Each match is represented by a â€snippetâ€™ â€“ a few lines of the pageâ€™s content, which feature your search term(s). Snippets allow you to see, at a glance, what a page is all about.
Google Search owes a large part of its success to PageRank, a unique algorithm thatâ€™s used to rank pages based on your search query. However, Google has taken a proactive approach to enhancing the search experience, and has expanded its search offerings with new technology such as Search by Image, Voice Search and Knowledge Graph. Whenever you perform a search, there are some essentials to bear in mind. Firstly, searches arenâ€™t case sensitive, which is one less thing to worry about. Also, Google doesnâ€™t actually search for common words such as â€Iâ€™ and â€theâ€™, even when you type them into the search bar. Along with these, and as a general rule, you should lay off the punctuation, as some punctuation marks double up as search commands, which can affect the accuracy of your results. Beyond these basics, you can limit your searches to particular websites, domains and file types, or use â€search operatorsâ€™ and Googleâ€™s Advanced Search page to craft a sophisticated set of search rules. Over the next few pages, youâ€™ll learn how to do all of the above and find out how to get even more out of your Google searches.
