If you've read the "Google Patent Web Level technology PageRank" or Google's PageRank technical instructions, you might be able to endorse the issue I'm going to talk about in this article.
Why would I ask such a strange question? It's not surprising, because the problem has gradually become the focus of attention and is beginning to bring trouble to everyone. Some people say that there is no such problem at all, and some people think it is just a myth. -Is there a problem with the page level leakage? If so, how serious is this loss? I think it's time to explain the problem.
opponents say:
against the page level will be affected by the leakage of people think: a page has its determined page level (PR value). Google's page hierarchy only partially determines the number of pages that the page links to because of the PR increment that this external link obtains. In this process, the Web page itself PR value has not actually suffered loss. In other words, if page A has a certain page rank, then no matter how many sites it is linked to, page A's page rank does not change.
My explanation is as follows:
This view is indeed almost unassailable, but they ignore the fact that since a single page A may have other links (internal or external links), and we are talking about a site, then for page a site, page level is likely to loop back to page A, This possibility is not meaningless. Although PageRank is based on the web rather than the site, but we all know that, according to the definition of the site, it is actually a Web page composed of a system.
A unique feature of a Web site is that each page within it is tightly linked. This close link means that the pages on the site will benefit from links to other pages within the site. Conversely, if it links to an external Web page, it will not get the benefit. That is: the page level leakage problem on your site will not cause any direct impact, the impact is indirect. Those who insist that the impact of the page level leakage does not exist, the concept of page hierarchy is too simplistic understanding.
let's start with an analogy:
first assume that there are 1,000 yuan magic money in my hand, I can give you, but you have to follow some rules of the game: rule one is that you have to give your money to 5 members of your family and two strangers; Rule number two is the people who get the money, they want to give you half of the money they got, to you or 6 other people. Rule three and the last rule is that you can allocate the 1,000 dollars to each of the 7 people (i.e., the allocation ratio is up to you and allow someone not to get the money) at any rate.
Now let's see how much magic money your family has at the start of the game. Nature is 1,000 pieces. According to the human nature to infer: you are prepared to do two things, the first is to ensure that you get the most magic money possible, and the second is to ensure that you do not get the money can be your other family members. So when you allocate the money for the first time, you don't give it to those two strangers at all. And when the money is given to 5 family members, the person you think is the most likely to give you 50% will get the most money. Of course, to avoid suspicion, you can't give the person all the money. And if one of your family members has given his money to a stranger, there is nothing to lose, but at the same time you are not maximizing the opportunity I give you. The wasted opportunity is your "leak", which causes you to actually get less money than you can get.
similar to this, a Web site is like a family, and its internal pages are like family members. You can only rely on your own web pages to return half the magic money you get from those external pages. And if the pages don't allow you to leave the magic money they get, you can only expect to get the money from your own web page. For those external pages, they only give their money back to their website.
Now we can conclude that
Page level leakage problem does exist, but it is reasonable, and will not cause a direct impact on the site. In fact, we can say this: the loss of page rank causes you to not get the level of page you were able to get, that is, you get a lower level of page than you can get.
Is the
of the page level so important?
now the new problem has come, is it possible not to external links to prevent the loss of page level? The answer depends on how many pages you need for your site, how competitive you are in your field, and whether the page level you expect is consistent with your page. The best way to do this is to read the "page Rank disclosure" mentioned at the beginning of our article. But here, one thing we can be certain of, even in the most competitive areas, the most common scenario is that for a site, only some of the pages need a higher page level to get a better ranking, rather than all the pages within it. There will also be situations where people first worry about the loss of their page rank rather than trying to distribute the level of the pages on their web sites well.
What should we do?
links to external sites is not a benefit to you. It can increase your site's ranking in search engines and user browsing opportunities. The only downside is that it also causes a loss of page level. Because of this, I would like to put the page level we are talking about the loss of the problem is called "page level pay" should be more appropriate. That's why I didn't rush to give it a definite name at the beginning of the article.
The easiest solution for
is that you should link to them rather than refuse to share your page rank, for those who bring you more benefits than those that give you a loss of page rank.
if I want to buy a coat, a shop is 50 yuan, and the other shop is sold to 75 yuan, then of course I want to buy that piece of 50 yuan. I would like to cite this example to illustrate that you should minimize the level of the page loss, but do not be afraid of this loss and deny to those who can make you benefit from the site to share your page level.
