Was the Internet searchable before there was Google?

Sometimes it seems as if it wasn't True, there were other

search sites, such as www.altavista.com, www.askjeeves.com,

remembers that, although they made it easy to search for

something, they made it very difficult to actually find anything.

Then Google came along, and suddenly the world changed Itapplied its "special sauce" to searching, and the rest is history.Put simply, no search site on the planet comes near to Google

in the speed and accuracy of its searches

But if you think searching is all that Google is about, you'remissing a lot Google offers loads of services in addition to

searching, such as maps, email, personalized home pages, freeblogging, image-editing software…the list is long and gettinglonger every day

This book will help you get the most out of using Google and all

of its tools Whether you want to blog, send and receive mail,take a virtual trip around the world, find a long-lost high schoolsweetheart, get a great deal online, or a lot more, you've come

to the right place

Trang 17

Let's start off with the most basic question: Why bother to useGoogle? After all, there are other search sites out there

It's true that there are other search sites, but none are as fast

or effective as Google Google doesn't necessarily scan more ofthe Web and index more websites than any other search

engine That's not really what's important What it does betterthan any other site is deliver more accurate results At times,the results seem so uncanny that you almost feel as if Google isreading your mind (You'll learn more details about why Google

Trang 18

graphic-rich ads, they were slow to load, and you often had towade through a great deal of advertising and unnecessary

material until you got what you wanted

With Google, your results are front and center

There are reasons beyond accuracy and presentation to useGoogle as well Google is constantly coming up with new tools

to integrate searching and other Web services into your life

Google Desktop, for example, can search your hard disk in the

same way that Google searches the Web, and you can even seeboth sets of results at the same timewhat's on your PC as well

as what's on the Web And there are plenty of other exampleslike this

Trang 19

Before you can understand how Google works, you probablyshould have a basic idea of how the Web works When you visit

a website, your browser is actually contacting a web server, acomputer whose job is to deliver web pages So when you click

a link, your browser contacts the server and says, "Send methis page." The server takes the request and then sends thepage to the browser, which displays it on your computer

In some very basic ways, Google works just like other search engines Its basic operations are exactly the same Like allsearch engines, Google is composed of three parts:

Trang 20

crawls the Web once a month Obviously, many sites changemore than once a month, and so Google also has a crawler

named FreshBot that crawls pages constantly.

The Indexer

The spiders send information about all the pages they find tothe indexer part of the search engine The indexer then does apretty amazing jobit creates an index of every word on everypage sent to it by the Google spider Not only does it indexevery word and every URL, it also keeps a record of whereevery word is on every page

Trang 21

A single server wouldn't be able to keep up with all the searchrequests that are done

And it all happens in a fraction of a second

Google's Special Sauce

All this search engine logic is nothing new or revolutionary Thistechnology has been around for years, long before Google was

a glimmer in its founders' eyes

So why is Google so good at what it does?

Google uses better algorithms than any other search engine,and constantly refines them Algorithms are sets of rules forperforming a particular task In Google's case, its algorithmsare responsible for taking your search request and deciding

which results to show you

Key Term

Trang 22

Google's case, algorithms are what determines

which pages it says match your search requests

Google's algorithms aren't particularly easy for mere mortals tounderstand, they're changing all the time, and they're not madepublic Google uses more than 100 factors in its algorithms Forevery search you do, it considers all of those factors and thencalculates a score for every possible matching page The pagewith the highest score is the first search result The page withthe second-highest score is the second search result, and so on

Some of the metrics are fairly obviousthe search term needs toappear on a page, for example Google's algorithms also factor

in the number of times the term appears on a page, whetherthe term appears on a prominent part of a page, whether it

appears in the title of a page, and many other factors

None of this is particularly revolutionary, either Many searchengines do the same thing

Google's real brilliance is in harnessing the collective

intelligence of the Web to figure out what was truly relevant,instead of merely relying on these kinds of rules Google alsogives a great deal of weight to the number and kinds of pagesthat link to a web page For example, Google figures that if aweb page has many sites linking to it, the odds are very goodthat the page is an important one And if important sites arelinking to that page, it's even more important

So Google calculates a page rank for each page, and that pagerank becomes a very important part of the calculation as well.For example, you do a search, and Google finds your searchterm five times on a page to which hardly any pages link, but

Trang 24

Google, as mentioned previously, is more than a search engine

It provides a whole complex of sites and services that this bookrefers to as Google tools These tools include things such as

Gmail web service, Google Local (previously called Google Maps) search service, and Google Desktop for searching your

computer

Google is such a great search site, but why bother using Googletools? These tools are in many ways as remarkable as the

Trang 25

Toolbar is used as an example of how to install software (To

see other downloadable tools, go to www.google.com, click the

More link at the top of the page, and then click the Google Downloads link on the left side of the page.)

Many of the Google tools or services that are websites, such as

Gmail, require that you sign up for a Google account After you

have set up an account, you won't have to set it up again Youcan use your single Google account as the centerpiece for all ofGoogle's services

To sign up, head to www.google.com and click Sign In On the right side of the page that appears, click the Create an

account now link The page shown in the nearby figure

appears

Fill in an email address, enter a password and retype it, chooseyour location, type what you see as the weird-looking text in

the Word Verification area, read the Terms of Service, and then click I accept Create my account That's all it takes;

Fill out this page and click I accept Create my account Then

you are ready to use all of Google's services.

If people fear one thing about Google, it's that Google mightinvade their privacy in some way That's a natural fear As

Google creates more and more services, it can gather an

increasing amount of information about you And there are alsoworries that Google tracks all of your searches, and it couldthen easily create a personal profile of you and sell the results

to the highest bidder

If you want the whole story of Google's privacy policy, head tothe Google Privacy Center at www.google.com/privacy.html Itspells out in a good deal of detail what information Google findsout about you and what it does with that information

But here, in a nutshell, is the scoop: When you create a Googleaccount, you need to enter basic informationyour email addressand password Google doesn't share that information with anyother website

information, and they can use it to identify you and the

searches you do They can subpoena your ISP and find out thesubscriber name of the person with the IP address at a giventime So based on Google logs and information provided by

your ISP, law enforcement officials can identify you and whatyou do on Google Google complies with subpoenas

Google also uses cookies, which are small bits of data placed

on your computer that Google uses to recognize you when youlog in Cookies can store your personal preferences and otherinformation For example, Google uses a cookie to recognizethat you have a Google account, so you don't have to log inevery time to use some Google services

to an individual So, for example, it might collect informationabout what pages are most popular among Google visitors Itaggregates information from many people's Web-surfing

Trang 34

Google is far more than a search siteit has grown to be a

sizable collection of services and tools, and the collection is

getting larger all the time No longer is Google a single searchsite; instead, it's a conglomeration of multiple sites And nolonger can you even call it Web-based because Google now

includes software that you download and run on your PC

This book often refers to tools and services Although there is alot of gray area in the definitions of these two terms, generally

Because of that, before reading the rest of the book, it's a goodidea to take a quick tour of Google so you can find the newesttools and services on your own

Search History,My Account, and Sign Out If I hadn't been

logged in, only two links would be there: Sign In and

Personalized Home (And when I clicked the Personalized Home link, I'd first have to sign in before I could get to my Personalized Home page.)

Now look at the links just above the search box These linkslead to several of Google's main services and tools These linksmight change over time, but at the time this book was written,

they linked to Google Image Search (Images); Google

Groups (Groups); Google News (News); Froogle

(Froogle); Google Local, which used to be called Google Maps (Local); and Google Desktop (Desktop) There's also a more

As you'll see in this book, there are many more Google toolsand services than there are links on Google's front page In

fact, this book doesn't cover all the tools and services that

Google has because there are too many So how do you find outabout a tool or service, or even discover which ones exist?
