How is Google PageRank calculated?
So to calculate the PageRank of given page A, we first take 1 minus the damping factor (d). D is typically set as . 85, as seen in their original paper. We then take the PageRanks of all pages that point to and from page A, add them up, and multiply by the damping factor of 0.85.
How does Google algorithm work?
Google’s algorithm does the work for you by searching out Web pages that contain the keywords you used to search, then assigning a rank to each page based several factors, including how many times the keywords appear on the page. Google references this index when a user enters a search query.

What is the damping factor for Google PageRank?
In the equation ‘t1 – tn’ are pages linking to page A, ‘C’ is the number of outbound links that a page has and ‘d’ is a damping factor, usually set to 0.85. We can think of it in a simpler way: a page’s PageRank = 0.15 + 0.85 * (a “share” of the PageRank of every page that links to it)
How is PageRank distributed between the pages of a website?
A website has a maximum amount of PageRank that is distributed between its pages by internal links. The maximum PageRank in a site equals the number of pages in the site * 1. The maximum is increased by inbound links from other sites and decreased by outbound links to other sites.
How does real mode work in PageRank calculator?
The calculator doesn’t treat them as orphans. Real mode calculates properly for orphan pages and dangling links. Note that if a page is linked to only from an orphan page then, since the orphan page doesn’t exist, neither does the link and and so the linked-to page can’t exist. This example demonstrates what happens:-
