Google pagerank update schedule for the year of 2013

Google is updating its PageRank information it uses daily. The information we have is therefore always out of date. Google releases PageRank information in integers whilst Google knows the decimal places. As PageRank is logarithmic we may see a PageRank of 2 but we do not know if it is 2.01 or 2.99 which would be almost a ten-fold difference in authority. Incidentally, Google boosts the effective PageRank of HomePages competing for a keyword to a minimum of 4.5.
PageRank is fundamental in webpage positioning for keywords on Google’s results pages. It is an indication of non-keyword specific authority. Google also tells us that nowadays it also relates to the website as well as the webpage. With regard to the website, Google is probably taking account of all the PageRank link-juice going to all the pages of the website. The best indication we have of this is the PageRank of the website’s HomePage.
The combination of webpage and website HomePage PageRank gives us the best indication of the potential strength of the webpage we plan to use to compete for a keyword. Compare this to these figures for the webpages on the top page of Google for that kewyord and you know the chance of your page achieving top page positioning.
