A live chat on Google Groups reveals a little bit more on system used to calculate the weight of a web page in the search engine most used network

Google PageRank has a few less secrecy in a session of Q & A group of Google Webmaster Help held in the last days of October, Matt Cutts, Mail Ohye and other Google-man responded to the questions of users and (just) the webmaster spigolose some questions about how to ranking web pages used on system most famous mathematician of the Internet.

The session did not lead to the publication of anything transcendental or PageRank is also in itself a carrier of universal truth unknown to most people, that is a trademark patented and documented. But the responses collected are used to dissolve some doubts about what really counts to climb the rankings of approval of the mega-cervellone mathematical Google. And to help generate other, to put it across.

Among the more interesting responses there is such as to ensure the maintenance of the PageRank of the pages in case of errors HTML 301, namely a permanent redirect the URL to a new destination. PageRank remains the same even if redirect recursive, but whereas the standard HTML 1.0 will grant up to 5 in the series is not to exaggerate the case.

The PageRank is then calculated differently in each language ecosystem when the content is translated, say the people of Google, and this will probably not be a Q & A to dispel any doubts about that. The search algorithm in the indices of Mountain View is changed often? And how often? “Both” is the predictable response, last year, tweak it amounted to more than 450.

Count the speed with which a page is loaded in the calculation of PageRank? Yes, probably counts a lot, even if the Google-man does not say so explicitly. Like say, between the lines, that if a blog post has many comments is ranked first in search results and links are not present on a site destination URLs of these links within varranno index calculated on based on PageRank.

Among the considerations are less clear there is the question of “if” and “if so, as” virtual age of a website influence its position in the research. In this case, the G-man first argue that ‘yes, if your domain has been credible for years it can help “and that buying a new domain, move their own content and hope to have the same PageRank is always mere utopia . Then, however, expressed as contradicting earlier revealed that “in most cases it does not matter, because we have the best information, not just those older.”
