Analysis of links to Seo

Why are so many webmasters busy working on links all day? I believe that everyone must be directed at PR. Many webmasters are so happy to write this post in 30 minutes and give some suggestions to webmasters, of course, I am also a newbie. I don't know about Seo optimization. I just want to talk about my own feelings and shortcomings. Please include them more!

To get started, let's talk about the concept of the link:

External link: ExternalLinks. External links of this website generally refer to links from other websites to this website.

Internal link: InternalLinks. Links between webpages on the website.

Reverse/import link: backwardLinks or incoming/inboundLinks. The meaning is similar to that of "external link", which refers to the link from other websites to this site.

Export link:Outgoing/outboundLinks. A link from this website to another website.

In the factors that affect the website PR, the importance of friendship links is not too much, whether it is GG'sAlgorithmThe external links, as an important reference value of the algorithm, have not changed. Compared with optimization and cheating, the natural factors obtained through high-quality PR external links are more favored by search engines!

Gg and Baidu look at the importance of a website and judge the relevance of a website. It depends on how many external connections the website has, it is not an external connection of some [junk! High quality always comes first,I believe many Webmasters have read this post carefully, but I know little about it. This has led to many webmasters, search for links.

In addition, I found that there are more and more people working on website sites, and QQ groups are everywhere shouting for free indexing. (I rely on it, what is free indexing? I'm all depressed. How can they say that ...) I am speechless, because the site PR will be greatly improved (so many sites are linked to it, can it be unpleasant to upgrade ?), However, some people with bad intentions often rely on this channel to do bad things-such as the rise of PR on the website site, and immediately turn into other types of websites, such people are shameful, serious BS!

For Gg, the link is its "lifeblood" and is also the key to its success. As soon as Google has the opportunity, it will instill in you the idea: go out and find a link, otherwise your website will not be accepted by us. Gg once stated at a search engine Academic Conference the minimum standards for indexing websites, that is, when you submit a website to Google, you must at least ensure that there is an external link.

However, the importance that Gg attaches to the number of external links on a website does not mean that you can establish a connection with any website without policy. This is because Google is not simply determined by the number of external links to the website. In that case, all website administrators have only one thing to do-crazyExchangeLink! Khan...

So, is a website with Pr = 0 linked to many high-quality, high PR websites, the more it will do, the better?

I wonder how many people have noticed this problem? Here, the gg pr system assesses the importance of a website. The quality and quantity of external links of a website are an important reference value. I believe everyone knows this, but there is also an important small parameter X-because I don't know the name of this parameter -. -~, This indicates the number of external links of the station you want to connect. This is two yards from the number of connections mentioned above. Do not confuse them.

Let me give you an example!

Taking my website for example, my website has just been built for a month, so Pr = 0 now there is a website with Pr = 4. If my website is its only external link, then Gg will believe that my website is its best external link, which is equivalent to 1pr points for my website, which can significantly increase my PR score, this is especially significant for the new station! (Hey, Will someone help me with this ?)

However, if PR = 4 already has dozens or even hundreds of links, what is the situation? -- Gg only thinks that your website is one of its many links. The PR score I can get is basically 0. In this way, the more external links on my site, the lower the PR score. Similarly, if you connect to a site with a PR value of only 1, but I am its only external link, the PR value I get is far greater than that of the website with Pr = 4 and external links of 100.This is like dividing an apple. As for how to score, I don't know if you understand it?

It seems that this problem is becoming more and more complex now. In fact, I am also confused when talking about it. When talking about it, I will go through the wrong question. I should try to make it clear, and you have to read it carefully.

Let's take a look at the formula for calculating the PR score:

Pr ()=(1-D)+D (Pr (T1)/C (T1)+...+Pr (TN)/C (TN ))

Pr (a) indicates the PR score added to your website by the System Based on PageRank from an external link site T1; PR (T1) the PR value of the external link website. C (T1) indicates the number of external links of the external link site. Everyone should remember that the score of a website is only 0.85 of the PR score of the website, and the score of this 0.85 is evenly allocated to each external website connected to it.

Suppose my website with Pr = 0 is linked to a website with Pr = 4 and external links = 9. The formula is as follows:

Pr (aka)=(1-0.85)+0.85 * (4/10)

Pr (aka)=0.15+0.85 * (0.4)

Pr (aka)=0.15+0.34

Pr (aka)=0.49

That is to say, if my website gets a link with a PR value of 4 and a number of external links of 9, my website will get a PR value of 0.49.

Let's take a look. If my website gets a link with a PR score of 8 and a number of external links of 16, my PR score will be:

Pr (aka)=(1-0.85)+0.85 * (8/16)

Pr (aka)=0.15+0.85 (0.5)

Pr (aka)=0.15+0.425

Pr (aka)=0.575

0.575! O (lead _ lead) O... haha, if there are several more such links, PR is just a piece of cake!

For your convenience, let's outline the outline:

1. friendship links are often expensive and inexpensive. If you are too busy, you will not be able to find any links to the website. Many website sites, PR increased rapidly within January, but suddenly died that's why.

2. When creating external links, the PR value is high, but you must check the number of external links.

3. friendship links are preferably websites with the same website and Related Websites. Such links can be exchanged with each other to gather user groups. Other important websites can also consider this,Gg's dependence on external links has always been very heavy.

4. I think more about it...
