What is Google…??? "Googol" is the mathematical term for a 1 followed by 100 zeros. Google is a Web search engine owned by Google.Inc, and is the most used search engine on the Web.

What happens when you Google? 10 © www.udaysatya.blogspot.com

What is Page Ranking ??? 11 © www.udaysatya.blogspot.com

How Google Works 1. Phrases When you search for multiple keywords, Google first searches for all of your keywords as a phrase So, if your keywords are loyola junior college, any pages on which those words appear as a phrase receive a score of X. 12 © www.udaysatya.blogspot.com

How Google Works 2. Adjacency Google then measures the adjacency between your keywords and gives those pages a score of Y 13 © www.udaysatya.blogspot.com

How Adjacency Works A page that says Loyola Academy, Degree and Post Graduate College as well as Loyola Academy Junior College were founded by Rev. Fr. T. Balaiah, S.J. in 1976 at Old Alwal, ... will receive a higher adjacency score than a page that says Alwal is also home to some of the famous schools and colleges in secunderabad like the St.Ann's High School, Bolarum which was set up in 1876 by a group of nuns from Italy. The other schools in the area are Valerian Grammar School (Bollarum), Loyola Academy, Model Mission High School, KV Bolarum and the Raja Praja High School… 14 © www.udaysatya.blogspot.com

How Google Works 3. Weights ,[object Object]

A page that has the word Loyola four times, Junior three times, and College seven times would receive a higher weights score than a page that only has those words once15 © www.udaysatya.blogspot.com

Google takes The phrase hits (the Xs), The adjacency hits (the Ys), The weights hits (the Zs), and About 100 other secret variables calculated by different algorithms And, finally, displays the top 1,000 in order. 16 © www.udaysatya.blogspot.com

Google Tip #1 Be specific ... because if you aren’t specific, you’ll end up with a bunch of garbage! 18 © www.udaysatya.blogspot.com

Google Tip #2 Use quotes to search for phrases 20 © www.udaysatya.blogspot.com

Google Tip #3 Use the - sign toexclude 21 © www.udaysatya.blogspot.com

Google Tip #4 Use the + sign toexclude 22 © www.udaysatya.blogspot.com

Boolean Logics a aANDb b c cORd d cNOTb c b b 23 © www.udaysatya.blogspot.com

Default is AND If you search for more than one keyword at a time, Google will automatically search for pages that contain ALL of your keywords A search for Loyola College Alwalis the same as searching for Loyola AND College AND Alwal 24 © www.udaysatya.blogspot.com

#5 Boolean OR (|) Sometimes the default AND gets in the way. That’s where OR comes in. 25 © www.udaysatya.blogspot.com

#6 How Insensitive! ,[object Object]

So, the following searches all yield exactly the same results: Hero HondaKarizma herohondakarizma HERO HONDA KARIZMA hErOhOnDakArIzMa 26 © www.udaysatya.blogspot.com

#7 Google’s 10 Word Limit ,[object Object]

Any keyword past 10 was simply ignored.

Google now accepts up to 32 keywords.

For example, if you search Google for it’sa * world, Google shows you all of the pages in its database that contain the phrase “it’s a small world” … and “it’s a nano world” … and “it’s a Linux world” … and so on. 29 © www.udaysatya.blogspot.com

#9 Order of Your Keywords Matters Because Google searches for phrases first, the order of your keywords matters 31 © www.udaysatya.blogspot.com
