How Search Works An Introduction
What Does Google Do When You Search? Search the index:When you click the Google Search button, Google races through its billions of web pages to find every page that contains the word or phrase or group of words you've used. Evaluate each site's reputation: Google looks at how often other websites link to these pages to determine how popular or useful each one is. Rank the web pages:Having scrutinized the web pages in terms of their relevance to your search words, Google presents your results, with what we believe are the most useful pages at the top. Analyze the web pages for relevance:Google screens web pages in the index to see which ones are most likely to have what you're looking for.
Understanding Search Finding the Right Keywords to Use
What Matters In My Search Query? Think of a topic or question you would like to search for. Pick three or four keywords to use in your search query. What happens if you reorder them? Add capitalization or punctuation? What if you take out a word?
Keyword Search How do you come up with the right words to search for? Can you remember a time when you had trouble finding what you were looking for? What makes certain searches hard?
Tips For Better Searches 1 Keep it simple. Describe what you want in as few terms as possible. 2 Think of how the page you want will be written. Use words that are likely to appear on the page. 3 Use descriptive, specific words. Avoid general or common words.
Think Before You Search What am I looking for? What do I want? What am I trying to find? What am I trying to find out? What keywords could I use in my search query? How would I talk about this? How would someone else talk about this? How can I describe this better? Which of these keywords are common or general words? Which would be more specific? Are there better words I could use? What kind of results am I looking for? Do I want a definition, a database, a list, a map, an image, a video, or something else?
Give It A Try! Pick a topic you want to find out about and brainstorm keywords to use in your search query. Remember: Keep it simple. Use descriptive words. Think of how the page you want will be written. And most importantly: Think before you search!
