What is pageRank Algorithm?
PageRank Algorithm is a sequence of
instructions which different Search Engines use for the calculation
of the search result i.e. SERP which comes after every search we made
for a specific keyword. And it gives priority to different factor
like Keyword Strength, Domain strength, Inbound link Score, user
data, content quality score, manual boost etc.

Summary: How Does PageRank Work?
PageRank is based on incoming links, but not just on the number of them - relevance and quality are important (in terms of the PageRank of sites, which link to a given site).
PageRank is only one of numerous methods Google uses to determine a page’s relevance or importance.
PageRank is based on incoming links, but not just on the number of them - relevance and quality are important (in terms of the PageRank of sites, which link to a given site). Bad incoming links don’t have impact on Page Rank. Ranking popularity considers site age, backlink relevancy and backlink duration. PageRank doesn’t. Content is not taken into account when PageRank is calculated.
PageRank does not rank web sites as a whole, but is determined for each page individually.
Each inbound link is important to the overall total. Except banned sites, which don’t count.
DMOZ and Yahoo! Listings don’t improve Page Rank automatically.
Each Page Rank level is progressively harder to reach. “PageRank is logarithmic in its calculation. In the same way that the earthquake Richter scale is exponential in calculation, so too is the mathematics behind Google PageRank. It takes one step to move from a PR0 to a PR1, it takes a few more steps to PR3, it takes even more steps to PR4, and many more steps again to PR5, and so one.” [Google Page Rank FAQ]
