How Search Works
Google engineer Matt Cutts explains how Google Search decides which search results to give you, based on your search query.
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.
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.
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.
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?
What Matters In My Search Query?
1 Every word matters.
Try searching for [who], [the who], and [a who]
2 Order matters.
Try searching for [blue sky] and [sky blue]
3 Capitalization does not matter.
Try searching for [barack obama] and [Barack Obama]
4 Punctuation does not matter.
Try searching for [red: delicious! apple?] and [red delicious apple]

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
Use descriptive, specific words. Avoid general or common words.

Think of how the page you want will be written. Use words that are
likely to appear on the page.2
Keep it simple. Describe what you want in as few terms as
possible.1
Think Before You Search
What am I looking for?
How would I talk about this?
How would someone else talk about this?
What keywords could I use in my
search query?
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?
How can I describe this
better?
What do I want? What am I trying to
find? What am I trying to find out?
Give It A Try!
Remember:
Keep it simple.
Use descriptive words.
Think of how the page you
want will be written.
And most importantly:
Think before you search!
Pick a topic you want to find out about and brainstorm keywords to use in your search query.
