Summarize several ways to protect and improve PR of website

PageRank is an important part of Google's algorithm. September 2001 was awarded the U.S. patent, the patent is one of Google founder Larry Page. Therefore, the page in PageRank does not refer to pages, but to Pec, that is, the hierarchical method is named after Peggy.

Google's PageRank measure the value of the site based on the http://www.aliyun.com/zixun/aggregation/8486.html "> External links and the number and quality of internal links." The idea behind the PageRank is that each link to the page is a vote on the page, and the more links it has, the more you will be voted on by other sites. This is called "link 17891.html" > popularity – Measuring how many people are willing to link their site to your site. PageRank the concept is quoted from a paper in academia--the more times it is quoted by others, the more authoritative it is to judge the thesis.

Google has a set of automated methods to calculate these votes. Google's PageRank score from 0 to 10;pagerank for 10 is the best, but very rare, similar to the Richter magnitude (Richter scale), PageRank level is not linear, but according to an exponential scale. This is a peculiar mathematical term, meaning that PAGERANK4 is not better than PAGERANK3--and may be 6 to 7 times times better. So the gap between a PageRank5 Web page and a PageRank8 page is much larger than you might think.

PageRank higher pages tend to rank higher than PageRank, which leads to fascination with links. Throughout the SEO community, people are busy scrambling, swapping, or even selling links, which has been the focus of the past few years, so that Google has modified his system and started to discard certain types of links. For example, a widely accepted rule that links from "link Farm" (Link factory) sites without content will not provide the PageRank of the page, Links from PageRank higher pages but content is irrelevant (for example, a popular comic book site links to a forklift spec page) and does not provide a PageRank of the page. Google chose to reduce the frequency of PageRank updates so as not to encourage people to constantly monitor them.

Google PageRank generally updated four times a year, so just on the new Web site can not get the PR value. Your site is likely to not see the changes in PR values for a long time, especially some new websites. PR value for the time being, this is not a bad thing, just wait patiently.

However, through this day Google PR changes, you can generally understand that Google may be given the PR value, most of the site's PR has increased more or less, but there is a small number of webmaster site PR was dropped, really someone happy people worry.

To get to the point, easy SEO I website optimization promotion Station online so far 1.5 months, Google PR from 0 climbed to 3, the author summed up a few how to protect and improve the site PR method for everyone's reference.

Do not change the site domain name.

Suppose you already have a PR value of 6 domain name, but soon after you want to replace it, because there is a better domain name. You can redirect the old domain name to the new domain name and move the old file to the new domain, but it won't work.
