PageRank
PageRank
PageRank is a link analysis algorithm, named after Larry Page, used by the Google Internet search engine that assigns a numerical weighting to each element of a hyperlinked set of documents. It is effectively casting a vote for the other page . The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page's importance from the votes cast for it. How important each vote is is taken into account when a page's PageRank is calculated.
Paid for SEO, still have PageRank 0
For people building a new site, however, this is a real drag. Buy a domain name, build a nice site, get a bunch of inbound links from other sites, and you could still be "stuck in the sandbox" for months, waiting to show up in the search results. Start out with a definition. The sandbox is where Google puts new Web sites for anywhere from one month to three months or longer; their intent is to avoid having new sites pop up out of nowhere to be top o' the page results for a specific search. It's one way that Google maximizes the quality of its SERP (which you'll recall are search engine result pages). One way that I've found for dealing with this is to put up something, anything, related to your new domain name as soon as possible, even if it will be completely replaced by your real site once it's built. Not having PageRank doesn't mean that you don't show up in search engine results! To see if Google knows about your site at all, you need to use the special search pattern of site: followed by the domain name. To see about findability.info, for example, I'd use site:findability.info. Then look on the top right to see how many pages are indexed.
How is PageRank calculated?
PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))
Kot del Googlove iskalne tehnologije, gumb PageRank 
prikazuje
uvrstitev glede na pomembnost, ki jo določa več dejavnikov, vključno s
številom pomembnih strani, ki so povezane s to spletno stranjo. Večje
kot je število pomembnih strani, povezanih s to spletno stranjo, višja
je ocena PageRank. Več o tem lahko izveste v našem Pregledu tehnologije.
