Internal links can also improve the Web page PR value

The PR value is page index, is Google to determine the quality of the site link a standard, although now the PR value in the Google ranking factor in the weight is very low, but we are very concerned about it, and even a lot of sites to buy high PR value of the chain of the site, so that was fired to the uproar Almost every major forum site has sold outside the chain of advertising, including some portal sites are also selling outside the chain, a link less from hundreds of yuan, many tens of thousands of dollars. Outside the chain really to improve the site PR useful?

The answer is yes, but the role is very small, if the site itself PR for 1, in the PR value of 8 of the site home to do a link, want to add PR value to 3 or 4, is simply whimsical, according to the PR value Calculation formula: PR (A) = (1-d) + D (pr (t1)/C (T1) + ... + PR (TN )/C (TN), you may get only a few 1%. Besides you spend money to buy mostly is dark chain, to flow a little use also not, unless you really very rich, buy dozens of or hundreds of high PR value of the chain, otherwise can only be wasted. is the PR value improved there is no other way?

The answer is no, internal links can also improve the PR value of the Web page. You can design a good site internal links, a high-quality internal link structure generated by the PR value no less than high-quality outside the chain. The first is the site must have a certain scale, for example: the site has 1 million content at the same time to the home page, can be the phenomenon of how high the weight of the home page. A small site with only dozens of pages of hundreds of pages, and then a good inner chain structure is not likely to produce high PR value of the transfer, so it has to spend money to buy outside the chain, which is why say "content is king" reason.

The level of the Web site may be shallow, because the level two directory weight is higher than the level three directory, and so on. My Site PR value is 3, two level of the directory PR value is 2, three level directory but no PR value, shallow level directory is not only conducive to the transfer of PR value, more conducive to search engine crawl.

Recently also found an interesting problem: "www.xxx.com/xxx/" PR value is higher than "www.xxx.com/xxx/index.htm", do not know is the internal link form caused, or both themselves have the weight of the high and low points, I hope interested friends can study.
