 What is Google Page Rank?

Google is considered the best SEO search engine and its formula enables it to generate exact results that match up with key words. Google accounts for 1/2 of all search engine traffic this is why search engine optimization activity centers on Google. In this chapter we will look at the inner workings of Google and page rank.

Search engine optimization professionals must understand page rank. (PR) Frank is a mathematical formula designed by Google to rank the importance of a webpage.  The system originated n 1988 and involves a multitude of factors.  As such, search engine optimization experts must understand page rank.  This is so they can work to increase page rank. Google PR is a numerical ranking from one to ten.  A PR 5 is obviously greater than a PR The ranking defines the importance of the website.

The foundation of the Google page rank is based on a system of voting.  Through the use of a link one website casts a vote for another.  The more web sites that vote the higher the ranking of the other website will be due to the fact that several votes have been placed. Of course, the more important a website linking to the other web site the higher the vote. Relevant pages and web sites cast higher votes.  It is always important to acquire as many inbound links as possible provided they are from solid web sites. 

Outbound links are important as well.  All web sites have and outbound link on their pages in one form or another.  Outbound links can decrease the amount of out bound links and can decrease the amount of page rank that is passed from one site to the other. If a webpage has 8 out-bound links, it will only pass one eighth of its available Page Rank. If a page has only one out-bound link, it will pass 100% of its available Page Rank.

Summary:

- PR relies on the volume of in-bound links to page
- The quality of in-bound links is critical
- PR flows from sender to the receiver.
- Passing PR depends outbound link volume.

 The Google PR is determined for every page of the website. In fact, it may be different from page to page on the website. This is the result of a number of different factors.

 To check the Google PR of any webpage download the Google Toolbar from https://www.google.com/intl/en/toolbar/ie/index.html
The green bar in the toolbar indicates the value of the PR from 1 to 10. It may take three months for page rank to show up for new sites.

 Below is a screen shot of the Google Tool bar. The green bar shows the Page Rank as 10.

Here is a simplified formula to understand Google Page Rank. Here is a quick tip on passing page rank: a PR 5 page as it will pass 5/2 which is 2.5 PR while a PR7 page will only pass 7/3 which is 2.3 PR. See the following graphic:

The PageRank of 3 is 4.8 and I arrived at by adding the total PR flowing from webpage 1 and 2:
 PR of webpage 3 = (PR of webpage 1)/2 + (PR of webpage 2)/3 = 2.5 + 2.3 = 4.8

 Examine the following:

 0 - Black listed or new sites or pages
1 – Low PR of little use
2 - Low PR of little use
3 - Low-average PR with some value
4 - Average PR among all sites
5 - Good PR and a good prospect
6 - Very good PR and extremely valuable.
7 The above are tremendous but costly.

Of course, it is never wise to ignore of assume all low PR sites are of no value. They do possess a number of linking benefits.
More about Google Search Engine and its methodology:

Google uses a number of programs to process information into its databases. Three of the most important programs are:.

1. The crawler called Googlebot is what finds new pages.
2. The indexer stores information in databases.
3. The query processor is what generates the very meaningful results needed when searching.

More on GoogleBot - Google's web crawler

Googlebot is s web crawling robot.

Googlebot works by sending requests to website pages on the WWW and retrieving them for the indexer. The Googlebot finds web pages by crawling across hyperlinks, and keeping a record of all the hyperlinks it encounters on every page visited. The record of hyperlinks is Later also crawled.
This robot sends request to web pages and retrieves them for indexing. A record of every link it indexes is logged. 

The robot also keeps a record of the frequency of visits to the site.  This will determine how often it should be crawled.  If a website has not changed in a long period of time it will not get crawled.  This is how Goofle stays up to date on news and information websites. The Google Freshbot will pay a particular attention to those sites crawled more frequently.   Constantly updating a web site is highly recommended

What are Google Advanced Operators

These operators are used by search engine optimization professionals when they assess the indexing of websites in the search engines. Advanced Operators are query words that have unique meaning to Google and offer additional search engine optimization information in regards to a search. These operators aid in fine tuning a search and making it more specific as well as relevant. Consider the following best SEO examples as search engine optimization illustrations:

1. Link:
 The Advanced Operator (link :) (Link:www.google.com) will search for all links that point to www.google.com.
 
2. related:
 The Advanced Operator (related :) (Related: www.google.com) will list all web pages that are similar to Google's own webpage.

3. info:
 The Advanced Operator (info :) (Info: www.google.com) presents all the information Google possesses about its home page.

 Many of the Advanced Operators involve punctuation marks as opposed to words.

For example:

 “” (the quote operator) – The Quote Operator employs the use of a phrase by placing the phrase in quotes. For example:
“You Drive Me Crazy”

+ (the plus operator) - The Plus Operator is when words and phrases are added together to make a search more specific. For almond oil for face, just type in:
almond oil +face

This will eliminate irrelevant search terms.

- (the minus operator) - The Minus Operator is used to remove words to make a search more specific. For Boil (ulcer), you would type in
boil –heat

The minus sign extracts all terms that would be considered irrelevant.

Explaining Google Query Modifiers

Query modifiers are used to narrow down search results in the query. Important query modifiers are:
 
site:
Inclusion of (site:) in the query makes sure Google only generates results found in a site. site:www.google.com finds pages within Google only.

allintitle:
Inclusion of (allintitle:) in the query makes Google provide the results of the search term in the title. As an Example, the search term:
 allintitle:google search
 This will display websites that only contain "google" and "search" in the title.
 
intitle:
Inclusion of (intitle:) in the query looks for words in the title and the webpage. For example:
intitle:google search
displays the webpages that contain the word "google" in their title, and contains the word "search" elsewhere in the document. Please do not use spaces between the terms.

allinurl:
Inclusion of (allinurl:) in the query limits the responses to those who have the URL in the title.  For example:
 allinurl: google search
displays only those webpages that have both "google" and "search" in the url. allinurl: works only on words, and not on other URL components. It ignores any punctuation marks.

inurl:
Inclusion of (inurl:) in the query makes Google generate only those results that have the search term in the url and elsewhere in the document.

inurl:google search

displays all documents with the word "google" in the url, and  "search" somewhere within the document (url or anywhere else). Avoid using spaces between the terms.
