Brief History of Google
Brainchild of 2 Stanford Computer Science graduate students: Larry Page and Sergey Brin
Google.com was launched in 1998 with an initial investment of $1 million, 8 employees.
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Google Today
“Google, age 8, is pulling in $10 billion a year in revenue, is worth about $125 billion.”
(Lashinsky, 88)
A recent rating report shows that Google accounted for 49% of the searches performed in 2006. (Nielson Net Ratings, July 2006; http://searchenginewatch.com/showPage.html?page=2156451)
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Google’s Mission
“Google’s mission is to organize the world’s information and make it universally accessible and useful.”
????????????Question: Does Google organize information--or does it just help you find stuff?
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
How Google Works “98.8% of its revenues result from selling advertising.” (Miller, 14)
Similar to magazine advertising, Google attempts to increase the numbers of site visitors so they can generate more money from their advertisers.
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Google’s Advertising Business (continued)
AdWords sells targeted keywords to advertisers; when users search using a keyword, the advertiser’s “sponsored listing” is displayed. If a user clicks on the listing, Google gets paid.
AdSense places small ads on non-Google websites. Google generates an ad based on the page’s content; when a visitor clicks the ad, both Google and the site owner get paid.
The Anatomy of a
Search
The typical Google search takes less than half a second to complete. (Miller, 17-18)

Google’s PageRank Explained and how to make the most of it by Phil Craven
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
How Google Builds Its Database
Most of the pages in the Google database are found by Google’s spider software.
Pages discovered by “GoogleBot” are copied onto Goggle’s document servers.
Google creates an index to stored web pages
The flaw? Pages without a fixed URL slip through the cracks
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Page Ranking Components
1.Text analysis: font size, usage, proximity, neighboring pages
2.Links and link text3.PageRank: web page importance (not web site) determined by counting pages linking to that page. PageRank is a numerical ranking from 0 - 10.

A cheat sheet for raising your I.Q. score*
* (intelligent query)
1. What do you want to find?2. Construct your query using as many
keywords as needed. Consider the Advanced Search page.
3. Evaluate the matches--refine your query.
4. Save the information that best meets your needs.
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Is it possible to use too many keywords?
Google searches only the first 32 words of your query
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Google is not case sensitive
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Word order is important
Google weights the importance of keywords in order of appearance first keyword is most important second keyword next etc.
Evaluate your results; the top results may be the same no matter what the word order. The difference is more significant as you move deeper into the result listings. (Miller, 29)
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
“and” is assumed
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
OR must be capitalized
When you want to conduct an “or” search, make sure to insert it in all uppercase--or Google will ignore it as a stop word.
You may also substitute the “pipe” | for OR
The OR operator is the only Boolean operator accepted by the Google search engine.
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Where IS that “pipe” key?
Located just above the enter (return) key. Don’t forget to shift!
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Common words are automatically
excluded Google ignores: and or where how what the all other common words in your queries
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
So--if you want to slow the search…
Include a stop word!
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Including Stop Words
You can override the stop word exclusion by telling Google that it must include specific words in the query.
Be sure to include a space before the + sign, not after it+how a search engine works
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Excluding Words from Results
To exclude a word from your search, use the - operator
Include a space before the - but not after
pathfinder = 19,000,000
pathfinder -mars -nissan
= 17,100,000
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Taking Advantage of Automatic Word Stemming
Google doesn’t let you use wildcards to indicate different word endings: book*
Google incorporates automatic word stemming: it automatically searches for all possible word variations.rain = “rain” “rained” and
“rains”
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Searching for Similar Words
Google lets you search for similar words by using the ~ operator
Example:~cheap yieldsdiscount, low cost, affordable
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Searching for an Exact Phrase
“Googling is using the popular search engine Google.com to look up someone's name in an effort to find out more about them. You might Google your neighbor, your old college roommate, or someone you've recently met to see what information is available about them on the Internet.”
“laurie logsdon” lincoln ne
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
“Because Google has a ranking system, there is an unsubstantiated belief that the more Google returns a person has, the more important they are.
To Google someone, enter their name enclosed by quotation marks in the Google search box like this: "person's name". If you Google yourself, it is called autoGoogling or egosurfing.”
(definition from Whatis.com)
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Searching for Words that Don’t Appear
Together If you want to search for documents where two words don’t appear side-by-side, insert the * operator between the two keywords in your query
“happy * holidays”
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006

Narrowing your Search to Words in the Page’s Title Google offers two methods for
restricting your search to the titles of web pages: Single keyword: intitle:operator
Multiple keywords: allintitle:operator
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Narrowing your Search to Words in the
Page’s URL Similar to the “intitle:” and “allintitle:” , you can use the following operators to restrict your search to words that appear in web page addresses. inurl:unl allinurl:unl library
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Narrowing your Search to Words in the Page’s Body
Text You can restrict your search to body text only: intext:lps allintext:lps media
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Narrowing your Search to Words in the Page’s Link
Text There are two more operators similar to intext, inurl, and intitle (as well as allintext, allinurl, and allintitle). They are: inanchor:spinach allinanchor:spinach e-coli
Your search is restricted to words in the link text on a page.
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Searching for a Range of Numbers
To search for pages that contain items within a numerical range: Enter the lower number in the range followed by the …operator
mystery lexile 400…900
media careers $195000...$325000
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
List Similar Pages
If you find a page you like, you can search for similar pages using the Google related:operator
related:www.puzzlemaker.comThis is a great way to find a URL
you’ve forgotten!
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Find out more about a specific page
Google can tell you which pages link to a page it indexes
which pages that page links to which pages are similar to that page which pages contain that page’s URL
To get links to all this information on a single page, use Google’s info:operator.
info:www.fno.org
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Using the Advanced Search Page
If the last 30 slides were too much, but you still want to fine-tune your search, then use Google’s Advanced Search page. Raise your I.Q. score without using advanced operators.
Just fill in the appropriate selections on the page.

Using Google’s Directory
“When the quality of results matters, it’s sometimes better to view a list of pages that have been personally selected for their content and appropriateness…if it’s handpicked results you want, you want a web directory, not an automated search engine.” (Miller, 56)
http://directory.google.com
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006

Google Scholar
“Google’s web search engine indexes only that part of the Internet that is accessible to the general public.
Google Scholar enables anyone to search a database or scholarly journal and articles free of charge.
In some instances, only an abstract is available; to read the full text, you have to pay a one-time fee or...
frequent a library!” (Miller, 117-126)
Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Using Google Answers
Can’t find your answer? Visit Google Answers and let one of Google’s 500 professional researchers assist you--for a fee.

Laurie Logsdon, Oct. 2006Laurie Logsdon, Oct. 2006
Using Google Book Search
“ If there were a way to create a repository of all the world’s book content, it would put the Internet to shame.” (Miller, 475)
