Google launched the PageRank (PR) equivalent to the site is divided into measured, especially those who just do the station friends, and other sites to exchange links, most of the lack of PR value is rejected. With the site PR to 4, 5, or even 6, these friends will probably develop the habit of wearing the PR of tinted glasses review site. Google has rigidly divided the site into a class society, and you and I are destined to work for the upper class from birth. Fortunately, as long as the webmaster efforts, adhere to improve the level of the site is still possible.

We do not discuss Google's complex, lengthy algorithm formula for PR, and simply put it, Google believes that the popularity of popular sites pointing to external sites is not low. For example, I put a link on Sina home page, Google will think that my site is also very popular. Because the chain to a site outside the site must be more than one, so, add a weight to each site, plus other factors, the final calculation of the PR value of the site.

Last year, I just started to stand alone, although I do technical background, or by other intelligent webmaster to cheat. First, paste the common hyperlink HTML code:

<a href= "/news/index.html" title= "News Center" target= "_blank" > News Center </a>

When we do exchange links, use the above code webmaster accounted for the majority. Take a look at the code below and note that the Rel attribute is added:

<a href= "/news/index.html" title= "News Center" target= "_blank" rel= "nofollow" > News Center </a>

Haha, nofollow is no follow. Since PR is Google's patent, we have to start with Google's explanation of the Rel attribute. Nofollow originally appeared at the top of the page, a meta tag (meta), shaped like

<meta name= "Robots" content= "nofollow"/>

It tells the search engine not to crawl all the external links on the page. Later, Rel appeared. It can precisely control the search engine and not crawl a hyperlink. In this way, Google will not pass the current page PageRank value to the link, plainly, the link to the Web page can not get any resources from the current page, for search engines, this link is not the same as.

I before and some webmaster do friendship links, coarse eye A look, there are Web site name, domain name, but often ignore the REL attributes, especially rel hiding in a long pile of other code. Until last week, there is a webmaster initiative to find me to do a link, said a pile of good words, as a job fair type of site, regardless of design or positioning, do more meticulous, I think as long as the next update PR at least to 2. We exchanged links. After a few days, I point to open his website, want to casually look, accidentally found my link behind with rel= "nofollow", the code is as follows:

<a href=http://www.365zph.com rel= "nofollow" > Day Job Fair </a>

At that time I reluctantly shook his head, friendship links are inherently mutually beneficial things, why should such a shrewd?

Google itself has made a clear provision for the use of rel. (1) When the webmaster can not provide security for external links (2) the site to some of the chain to receive fees, but in order to avoid human intervention, and then affect the impartiality of the PR.

Can be seen, Google advocates to create a healthy internet, at the same time we can exchange links to enhance the value of their own site: let us work together to forge ahead together, and common development ha!

By the way AD, small station at present, home PR 4, welcome friends who are interested to exchange links.
