Specific Keywords Keywords Precisely describe your search topic. Expect to see on the webpage Do not search with a question Change the question into a query by answering, “What am I looking for?” • Who, what, when, where, why, how • Proper nouns • Where would you find this information?
Few words Try to limit your keywords to just 3. • Place the most unique keyword first. • Google will locate only the pages that have ALL your keywords.
Use quotation marks for exact phrases proper names: “George Washington” • quotes: “I have a dream” • location: “Springfield MO” • phrase: “All mimsy were the borogoves”
Use synonyms and related terms Google returns pages that match variations of your keywords: e-mail, email; child, children; • ~ Tilde operator takes the word immediately following it and searches for both it and its synonyms: ~inexpensive will find pages that contain inexpensive, cheap, affordable, and low cost. • If a keyword has multiple meanings that will cloud your results, don’t use it or qualify it. For example, web would find pages with a spider web, network, fabric, or membrane. • If there is a related word that will cloud your search, use the – operator to exclude the word from your search: mercury element –planet -car
Don’t use stop words the, on, where, how, to, a, I do, for, and are, at, be, but, by from, had, have, her, his, in, is, it, not, of • If a keyword is a stop word, add a "+" sign immediately in front of it, include a space between the "+" sign and any other words in your search: Star Wars Episode +I
Refine your query using search results Scanning summaries returned by your first search can give you ideas for keyword refinement. • You might notice an evocative phrase that better describes your target. • Google may even offer a suggestion, especially if you have misspelled a word
