Prepared & Presented by

PRIMER

• Founded: 15th September, 1997; Larry Page and Sergey

Brin

• Headquartered at Mountain View, CA

• Original USP: search engine; different from Rediff or Yahoo

• Global user share (as on September, 2013):

– Google: ~ 70%

– Baidu: ~ 20%

– Others: ~ 10%

• Business diversifications and expansions (since late 2000s)

• Ventured into Google products (collaborative measures)



HOW GOOGLE WORKS

• Google Crawler: A ‘Spider’ crawling on WWW

• Operates ‘really really ’ fast

• Data Updation = Information fed

by Google Crawler

(Updation frequency increases on National holidays,

low internet traffic periods…)

• More hit means higher probability of appearing your

website above others• Want high on rank? Use ‘extensively searched words in

Internet’ and cross-links

•

Key to swift search: Think like a Google Crawler…



UNDERSTANDING SERP

1

5

3

2

1. Title

2. URL (Uniform Resource Locator)

3. Snippet

4. Links into site

5. Additional Search Options

4



OFFERS from GOOGLE

• Use Google products for getting specific results:

– Images − Books

– Scholar − Translate

– News − and other…

•

Use region specific information• Use additional search options

• Bound time periods (Google allows customized search

option)

• Use results fitting your requirement; if you need a

verbatim, don’t go for ‘reading level’ results



GOOGLE IMAGES: FILTERING RESULTS

• Need a logo or picture? And your search results aren’t quite

what you want? Use colour filters inwww.images.google.com…

Searching on

‘TATA’ led to

this SERP



Same search +

colour filtering

done



CHOICE OF KEYWORDS

• Only ask what you need to know!

• Google searches EACH AND EVERY keyword

• Keep your query SIMPLE AND SHORT

• Don’t use the following parts of speech (unless required)

– Verbs (is, are, was)

– Adjectives (good, nice, beautiful)

– Articles (a, an, the)

•

No case sensitivity (USE, use, uSe, UsE are all same whensearched)



WHAT MAKES THE DIFFERENCE?

• Order of words

• Use some special characters viz. + # $ &

‘blue sky’ resultsversus

‘sky blue’ results



SOME USEFUL TECHNIQUES – 1

• Use inverted commas to club texts (viz. searching for Iam Indian and “I am Indian” will give different results)

• Myth broken: Use of comma is redundant

•

Bad at spelling? Don’t worry… Google will correct it foryou

• Searching for uncommon word? Worry not, Google will

show its suggestion AND results of your requirement

• Follow suggestions and trackers…




• Use mathematical operators (viz. 256.2546+352.14785)

in search box and hit enter…

• Some mathematical operators: + - x / sqrt ^ log log10

• Want to know the meaning of ‘Somnambulism’? Type

define somnambulism (or somnambulism meaning) andclick enter…

• Want to know today’s INR-USD conversion rate? Type

convert INR to USD and click enter…

• Want to convert 65ᴏC to ᴏF? Type convert celsius to

fahrenheit , enter data and hit enter…

• Caution: Google won’t tell you when units are

incompatible (try 50ml in cm!)



WHEN YOU DON’T KNOW WHAT TO DO

• Glance over EVERYTHING in SERP (but don’t browse

everything!)• Monitor suggestions-as-you-type (or incremental

suggestions)

•

Monitor incremental results as you type• Search related results’ list (refer to bottom portion of

SERP)

• Have a logo or picture and clueless about the company

name or source? Paste the picture in Google images andsearch…

• Have a music score and want composer’s name? Use

Google Search by Voice (experimental )



• Use shortcut key to identify texts (ctrl + F for Windows &

CMD + F for Mac)

(Note: With change of browsers, the function works differently.

Kindly pay caution while operating on different browsers)

•

NEVER SKIP words which you don’t know


Use ‘remittance’ in place of

‘immigrants send money

home’



APPLICATION OF BOOLEAN LOGIC

• Code is all about 1 and 0

• Use of query syntax

– AND: Actually redundant; space = comma = ‘AND’

– + (plus sign): Word succeeding plus sign will be present in ALL results (try

+economics)

–OR: EITHER of the preceding and succeeding keywords will be present (tryindian or agriculture)

– - (minus sign): Words succeeding minus sign will NOT be shown in query

results

– * (asterisk): Wildcard used when you know there is some text but don’t

know what it is (Caution: Position of asterisk is very important. Payattention while using it)

– .. (double periods): Used to limit number range

NOT, NOR, NAND are not recognized by Google. Don’t use them…



WHAT ACTS BEHIND 0.15 SECONDS

Google

Server

Index

ServersDoc

Servers

You Googledoesn’t

search theactual web, it searches the

indexed files

Google Cache

•

Simply a snapshot of a web page• Except some features, all other results are not provided in real

time

• Cache exists only if a page is full-text indexed



DEEP SEARCHING : NEED and FORMAT

Micro-irrigation

Micro-irrigation from site:

Web Organization

Deep Web (or Dark Web)

Little is indexed; need

special codes to access

Visible Web

Everything indexed

and shown



DEEP SEARCHING TOOLS - 1

• Site: Want information from a SPECIFIC WEBSITE (try industrial

policy site: wb.gov.in)• Filetype: Want information in a SPECIFIC FORMAT (try industrial

policy filetype:pdf )

– Some filetypes: doc, xls, pdf, jpeg, png, pptx, csv, txt, dat, kml

• - (minus): Want to omit a keyword from snippet shown normally(try icc – cricket )

— Caution: You must put a space before the minus sign

Remember:

• Mixing of operators allowed

• Put minus operator at first place

• Multiple minus can be used




• Intext (for very specific searching): Want some text or a

string to BE PRESENT in your result (trysite:indianchamber.net "economic affairs"

intext:finance)

Note:

• While quoting some

text, acknowledge the

source

• Check for credibility

Advanced Searching can also be done by application of UI



• Intitle: Word searched in TITLE only (try hybrid cars

intitle:mileage)

• Allintitle: Words or strings searched in title only (try

allintitle:hybrid car mileage site: ford.com)

• Allintext: Words or strings which appear in snippet (try

allintext:water air pollution site:envfor.nic.in)

• Allinanchor: Returns only pages that link to pages with your

search terms (anchor terms), BUT NOT in the actual pages(Can’t use this with other operators)




LASTLY

• Credibility check

• Incorporate variant data

• Verify quotes for plagiarism check

• Identify source using WHOIS database• Search one more time, differently …
