Retrieving data has been the challenges and that was done efficiently with crawling technology and along with efficiently used storage space and proper indexing process. Google was designed well to optimize the data structure so that results in favorable scaling properties for centralized systems.

We have created maps containing as many as 518 million of these hyperlinks, a significant sample of the total. These maps allow rapid calculation of a web page’s “PageRank”, an objective measure of its citation importance that corresponds well with people’s subjective idea of importance. Because of this correspondence, PageRank is an excellent way to prioritize the results of web keyword searches. For most popular subjects, a simple text matching search that is restricted to web page titles performs admirably when PageRank prioritizes the results (demo available at google.stanford.edu). For the type of full text searches in the main Google system, PageRank also helps a great deal.
Page Rank calculation is done through an iterative algorithm. But we are not interested here about the algorithm rather how it affects and what good practices can be done for better search behavior. So Page rank is nothing but a human behavior which can be explained as the random surfer visits web pages randomly and never hitting the back button. He randomly picks up links and keeps visiting the pages until is bored and then visit to a different page. The probability of visiting a page is its PageRank. So basically the page which is linked by number of other pages will have the higher PageRank. Similarly a page which is linked from (may be a single link) from a site like Yahoo or which has higher ranking status will also result a higher PageRank.

If the page is connected well with high number of linking, the percentage of the page will be getting added to the Google’s database while the next crawl happens. Because of that the indexing will be updated and the page may not appear always at the same position while searched.
