When exchanging friendly links, people tend to care about each other's PR value. Some novice friends also keep asking what PR is, what is Google PR, etc., which is a bit of a novice question. But it’s no wonder that not many people who have never been exposed to the Internet know, so what is PR value? The following is a tutorial for SEO novices. I hope that after reading this, you will no longer be unfamiliar with GOOLGE PR value (Google-PR). . PR value, namely PageRank, is the level technology of web pages. Taken from Google founder Larry Page, it is part of the Google ranking algorithm (ranking formula) and is used to identify the level/importance of web pages. Levels range from 1 to 10, with level 10 being a perfect score. The higher the PR value, the more popular (more important) the page is. For example: a website with a PR value of 1 indicates that the website is not very popular, while a PR value of 7 to 10 indicates that the website is very popular (or extremely important).
In the actual work of search engine marketing, it is found that the PR value of a website is not necessarily the only factor that determines the ranking of a website (and its included web pages) in search results, or even the main factor. Therefore, for the website PR value There are different understandings of the true value.
We can say this: the more external links a website has, the higher its PR value; the higher the level of the external link site (if Macromedia's website links to your website), the higher the website's PR value. For example: If there is a link to the XYZ.COM website on the www.com website, then the www.com website must provide some better website content, so that Google will regard the link from XYZ.COM as its investment in the ABC.COM website. of one vote. You can download and install Google Toolbar to check your website level (PR value).
The most direct way to check the PR value of a website is to install Google's toolbar. Download address: http://toolbar.google.com/intl/zh-CN/
So how is GOOGLE’s PR value derived? Please see the following information carefully prepared by Ultimate Fantasy: Google’s algorithm for the PR value of web pages: PR(A) = (1-d)+ d(PR(t1)/C( t1)+ ... + PR(tn)/C(tn)). PR(A) is the page A whose Pr value is to be calculated, d is the damping coefficient, usually 0.85, PR(t1)...PR(tn) are the PR values of each website linked to you, C(t1). ..C(tn) is the number of external links linking to your website respectively. From this, we can see that when the other party links to you, it is not that the higher the PR of the other website, the better, but the number of external links linked by the other website. Also very important.
The highest PR value is 10, and generally if the PR value reaches 4, it is considered a good website.
Does Google's Pagerank focus? The answer is yes. The system pays particular attention to those portal network directories such as DMOZ, Yahoo and Looksmart. Especially for DMOZ. A DMOZ link on a website is as valuable as a piece of gold to Google's Pagerank? At this time, the PR score of the DMOZ directory page that contains the website has become insignificant. I have seen some sites that have doubled in value just because they were included in ODP, and their PR scores were immediately improved on Google. That's because Google uses its own version of ODP for its website directory.
Now that we have a preliminary understanding of what PR is, how can we increase the PR value? Here are some methods:
Some main ways to improve PR value:
1. Log in to search engines and categories; don’t forget about friendly links. If you can get friendly links from websites with a PR value of no less than 4 and that are related or complementary to your topic, and rarely export links, the effect will be better.
2. Write some high-quality soft articles and publish them to large websites. If recognized by everyone, your URL will be reproduced by countless websites. This method is the best for increasing PR value.
3. The search engine indexes the number of pages of a website. The higher the proportion of indexed pages, the more beneficial it will be to increase the PR value.
4. Provide valuable website content and perform SEO optimization. It is also very important to increase PR value.
5. It is best to make the website included in the three well-known online directories DMOZ, Yahoo and Looksmart. If it can be included, the PR value will be increased very quickly.
6. Spend money to buy traffic. Or go to QQ, go to groups, go to forums and other popular places to promote
According to Google officials, the PR value can only be for entertainment purposes and cannot have an absolute effect on website rankings. When building external links to your own website, you should try your best to find websites with high PR values and few external links. . In this way, the more such external link sites on your website, the higher your PR value will be, thereby significantly improving your ranking.
