Is Google search algorithm patented?
Larry Page and Sergey Brin developed PageRank at Stanford University in 1996 as part of a research project about a new kind of search engine. The word is a trademark of Google, and the PageRank process has been patented (U.S. Patent 6,285,999). However, the patent is assigned to Stanford University and not to Google.
Is PageRank recursive?
The PageRank algorithm gives each page a rating of its importance, which is a recursively defined measure whereby a page becomes important if important pages link to it. This definition is recursive because the importance of a page refers back to the importance of other pages that link to it.

How does Google use PageRank to rank websites?
PageRank is the algorithm Google uses to rank websites. It uses the quality of other websites, and how many links from external sites the site has to calculate the site’s rank. The feature was named after Larry Page, one of the founders of Google. PageRank works by counting the number and… PageRank is the algorithm Google uses to rank websites.
How did the Google PageRank algorithm get its name?
PageRank is the first algorithm that was used by Google to rank web pages in its search engine result pages (SERPs). According to Google, the algorithm was named after Google co-founder Larry Page. In the original paper on PageRank, the concept was defined as “a method for computing a ranking for every web page based on the graph of the web.
How is the PageRank of a page determined?
The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it (“incoming links”). A page that is linked to by many pages with high PageRank receives a high rank itself.
What is the dampening factor in Google PageRank?
This is known as the dampening factor. If Page B then links to Page C, this receives 85% of B’s PageRank (72.25% of Page A’s). If a web page has no links pointing to it, that page doesn’t begin with 0 PageRank, rather 0.15. But things get even more complicated when there is more than one external link on a page.
