Google PageRank is a measure of the importance of a web page, ranging from 0 to 10. It is determined individually for each page based on the number and quality of inbound backlinks to that page from other relevant websites. It can take 2-3 months for a new page to be assigned a PageRank by Google. Outbound links do not help improve PageRank, and adding more page content does not directly impact PageRank - only inbound backlinks are considered in its calculation.

1. Google Parallel Page
Ranking

4. Google search engine has three main functional units:
• Google bot(web crawler code) that actually fetches all new pages from
web servers
• An indexer which sorts each words of a webpage and store the sorted
result in a database
• A query processor which gives the search result based on keyword input.
How google bot works?
• Google bot is web spider used to crawl old and newly formed webpages.
The fetched information by a crawler is fed into Google indexing
database.
• To keep Google indexing database up-to-date with the fresh information
Google crawlers regularly visit the most popular sites of the web in order
to keep track of the dynamic changes of the webpages.

5. Google indexer
• The main purpose of google-bot is to feed the crawled data to Google
database (indexer). The URL and the relevant content information of the
entire web can be found in Google’s index database. When we search any
information in Google’s search page, we actually search the indexing
database which gives us the relevant nformation with the link of a
webpage. Usually Google indexer does not index words like ‘the’, ‘is’, ‘on’,
‘of’, ‘how’, ‘why’- ignoring these common words makes the search result
more efficient.
Query processor
• For presenting the search result in Google page, there are three main
components-user interface(Google search box), query engine which is a
word or phrase matching program, search result formatter which actually
shows the searched result in Google page.

6. What is Page Rank or Google Page Rank?
• Page Rank used by Google is a measure of the
importance of a web page over internet. Page
Rank is a numerical number and ranges from 0
– 10, 0 being the weakest Page Rank and 10
being the strongest Page Rank. So the higher
the number the stronger is the Page Rank.

7. Is Page Rank determined for the entire site or
every individual page?
Page Rank is determined for each and every individual page
on your website, so each individual link of your site
may have a different PageRank.
But as the website’s home page or the main URL of a
website has have more chances of getting higher PageRank
than any other page as the home page will have most site
linking to it.
But in some cases a page may have more PageRank than
the home page if the page is more informative and highly
viewed.

8. How is PageRank determined?
• A. PageRank is determined based on the quality of the
inbound backlinks (do follow links only) to your website.
• Here quality means the website from where you have got a
backlink should be related to your website, meaning the
content on both the websites should be of same type.
• A backlink from a property related site to a technology site
cannot be treated as a quality backlink.
• The calculation of the PageRank is also dependent on the PR
of the website from where your website gets a backlink.

9. Is all the backlinks important to
determine PageRank?
• No, all the backlinks are not taken into
consideration for calculating the PageRank. The
links of type nofollow (anchor tag having
rel=”nofollow”) are not taken into consideration
for calculating PageRank.
• Google does not include nofollow type of links
while calculating PageRank.

10. How long does it take to get a Google
PageRank?
• New web page do not get a PageRank right away;
it takes a quite a while to get a PageRank.
• It almost takes 2-3 months to assign a PageRank
to a webpage.
• Pages might have PageRank internally but they
don’t get reflected. Google updates the PageRank
in every few months.

11. Does the number of outbound links from my
webpage improve my PageRank?
• No, outbound backlinks do not help in improving your
PageRank but it may be the cause for decreasing your
PageRank if there are lots of outbound backlinks which are
non-quality back links.

12. Does increasing the content of a page change
the PageRank?
• No, adding fresh and more content to a web page does not directly
affect the Google PageRank.
• PageRank entirely depends on the number of quality inbound back
links.
How can I find PageRank?
• You can find the PageRank of any web page by using Google Tool
Bar.
• This is an official extension from Google for the browsers which
shows the PageRank of any web page.

14. How to calculate page rank ?

18. Examples for page rank calculation

19. example
Now begin again with each page being allocated PR1. Link page A to page B and run the
calculations for each page. We end up with:-
Page A = 0.15
Page B = 1
Page C = 0.15
Page A has "voted" for page B and, as a result, page B's PageRank has increased. This is
looking good for page B, but it's only 1 iteration
After 100 iterations the figures are:-
Page A = 0.15
Page B = 0.2775
Page C = 0.15
It still looks good for page B but nowhere near as good as it did. These figures are more
realistic. The total PageRank in the site is now 0.5775 - slightly better but still only a
fraction of what it could be.

20. • Link all pages to all pages. Each page starts with PR1 again.
This produces:-
Page A = 1
Page B = 1
Page C = 1
• Now we've achieved the maximum. No matter how many
iterations are run, each page always ends up with PR1. The
same results occur by linking in a loop. E.g. A to B, B to C and
C to D. View this in the calculator.

21. Link page A to both B and C. Also link pages B and C to A. Starting with PR1 all round,
after 1 iteration the results are:-
Page A = 1.85
Page B = 0.575
Page C = 0.575
• and after 100 iterations, the results are:-
Page A = 1.459459
Page B = 0.7702703
Page C = 0.7702703
• In both cases the total PageRank in the site is 3 (the maximum) so none is being
wasted. Also in both cases you can see that page A has a much larger proportion of
the PageRank than the other 2 pages. This is because pages B and C are passing
PageRank to A and not to any other pages.

22. Top Factors for Google Ranking
1. Having backlinks from targeted keyword rich anchor text
2. Popularity of the backlinks pointing to your pages
3. Backlinks from unique domain names. Do not bring more the
2-3 links from the same domain name.
4. Use of keyword in the title of the page
Avoid the following Actions
1. Buying link from link brokers or building links with automated
software
2. Do not build backlinks with spam sites
