Use quotation marks. Using quotes around a set of words will direct Google to search for those exact words, in that exact order. Great for searching song lyrics!

Write "site." Typing site: (with the colon) after your keyword and before a URL will tell Google to search within a specific website. For example, "movie reviews site:commonsensemedia.org" will give you search results only within Common Sense Media's website.

Add a minus sign. Adding a minus sign immediately before any word (no space in between!) indicates that you don't want those words to appear in your search results. For example, "Saturn -cars" will give you information about the planet, not the automobile.
