Recently found that a lot of webmaster or seoer have talked about the use of nofollow this label, just two days in the book to see Zac, also saw the introduction of nofollow, feel nofollow in SEO or very important. So today, Qingdao SEO also come with you to learn about this nofollow application. If you have a good understanding of nofollow, this article can be abbreviated not to see, hehe ~.

In the past, the Qingdao SEO do site ranking which tube these details on the work, tell the truth at that time also do not know this label, more do not know what role they played in the SEO, and even now do SEO ranking or mainly rely on those original, outside the chain, anchor this article, friendship links, keyword density, such as the implementation of optimization work, I believe there are a lot of halfway webmaster or seoer same with me. Today, we are really a little sloppy, really still have to study hard, often some small detail work can play an absolute role, the so-called, the details of the success or failure, there is a certain reason!

The Nofollow label was originally proposed by Google, so the label is definitely suitable for Google search, but now many mainstream search engines have recognized the role and value of the label, this tag simply said its role is not to disperse the weight of the site, such as the site on some external links or less important links in the station, We can all by adding nofollow to control the site is decentralized weight, the so-called weight is often determined by the ranking of the site. So, in that case, the nofollow label is very significant for the site rankings. But many stationmaster or seoer does not have to this label to attract the attention or the attention, if you read the article, hoped everybody can pay attention, and applies to own website.

At present, nofollow tags are mainly used in some places:

1, forum and other interactive community or blog message. Because this kind of website usually posts more casually, can leave the link, want to know the website the export link is too many, is bound to disperse the weight of the website, so it is necessary to add nofollow to these places.

2, the site to sell ads link. Some sites have a lot of ads, these ads are mostly linked to each other's website, in order to avoid outbound links too much caused by the weight of the site to reduce the traditional method with JS and other jump code, here we can introduce nofollow tag, the link all add nofollow, It's not important to tell the search engine this link.

3, some irrelevant links on the site to join the nofollow. If there are "about us", "Contact Us", "recruitment" links, this link can count as irrelevant link, we can add nofollow to him, control is dispersed a certain weight.

Nofollow Label Application format:

The first:< metaname= "robots" content= "nofollow"/>

Write "nofollow" on the Web page's meta tag to tell the search engine not to crawl all the external links on the page.

The second kind of:< arel= "Externalnofollow" href= "url" >< span > Content < span ></a >

The most common thing we have now is simply to add a "rel=" nofollow to the a tag, such as:< a href=http://www.***.com/lianxi.asp rel= "nofollow" > contact us in this format. Place "nofollow" in a hyperlink and tell the search engine not to crawl the link.

Ok,nofollow since know, then try to use, but this label not with original, outside the chain of these work, nofollow compared to their role is very limited, the premise is that other SEO work has been done, some of the details of the work should do.
