What is Google PageRank?
According to Google - PageRank is Google's view of importance of a webpage. Pagerank is given out of 10.
Thus a webpage with a higher pagerank will be more important in view of Google as compared to the one with lower pagerank. Hence, a webpage with a better pagerank will get higher position in the SERP.
e.g. A webpage with Google PageRank of 5/10 will be more important and hence placed higher in Google SERP than the webpage with Google PageRank of 3/10.
How does Google determines a pagerank for any webpage ?
Lets see what Google says -
Let's examine the following figure for some better understanding -
In the above figure A,B,C,D,E and F are different webpages. Here you can see that page C has got a higher pagerank than page E, even though it have fewer links as compared to page E. It's because of the importance of the page from which page C is receiving a link and also the number of outbound links from that page. In the above case as you can see page B has got most importance and is having only one outbound link to page C, so up to 90% of its PageRank is carried to page C.
In the essence, a page with higher baklinks from quality pages (those with higher pagerank) will have a better pagerank.
Thus, improving your Google PageRank helps you by getting you more visitors through search engines and ultimately can result into better revenue from your website/blog.
