How to use the nofollow tag for website optimization

Nofollow is the attribute value of an HTML tag. Its appearance provides a way for the website administrator, that is, tell seo/seo.html "target =" _ blank "> Search Engine" do not track links on this webpage "or" do not track this specific link ". This tag indicates that the search engine link is not trusted by the author, so this link is not a trusted ticket.

Nofollow was initially designed to reduce the impact of spam links on search engine rankings. The tag indicates that the search engine link was not edited by the webmaster, so this link is not a trusted vote. If the search engine sees this, it will not trace and crawl this link, nor will it pass the link weight and the anchor text.

In fact, the majority of webmasters and seo hate to use rel = "nofollow" labeled webmasters or seoer, because it is a scam to get your link. As a result, you are white and white links to his station. We all remember the langyu seo incident a while ago. It is also a punishment for him to be dishonest. Then Baidu adjusted the algorithm and the ranking was adjusted back, here we will share with you that the nofollow label must be used with caution. Let's talk about how to use the nofollow label as the best one.

Nofollow and blog

Nofollow labels are usually used in blog comments, forum posts, social websites, message boards, and other places. Because any user in these places can freely leave a link, the webmaster generally does not know the website to which the link is connected, it is also impossible to view the verification in one way, so it is the most spam link.

Application of Nofollow in seo

Because the nofollow attribute can prevent crawlers from crawling and passing weights, many seo engines use some internal links to control internal link weights and pr flow and distribution. The most common application is to contact us, privacy policy, user terms, user registration and login links. These pages often have full-site links. If nofollow is not used, the weight of the whole-site links will flow to these pages equally. Web pages such as privacy policy are rarely concerned by users, and the possibility of bringing traffic through search engine rankings is extremely low. Therefore, the weight of the web pages that are less valuable to these searches is a huge waste.

Many websites use nofollow to control the weight flow and direct the weight to pages that need to be indexed and ranked. The overall indexing, ranking, and traffic increase significantly.

Now, I can see that many webmasters are stupid and have made such a mistake, that is, connecting to websites such as Baidu and google for free without adding the nofollow label and giving them white weights, is this worthwhile? Some websites also have payment tools such as Alipay and Caifu Tong, which are links of white and white, instead of using the nofollow tag. What's more ridiculous is that, some websites have direct links such as bad information reports and feedback centers in the last column, which wastes the weight of the website.

So how can we do this nofollow label? In fact, it is not very difficult for a basic seo or webmaster. Here I will give a simple demonstration, you can combine some tutorial operations on your own. <A href = "url" rel = "nofollow"> url in </a>. Url indicates that you do not want to export the unlinked nofollow tag.

Because too many spam links will affect the judgment of search engines, nofollow is now a good "spam link firewall ". Baidu, Google, Yahoo, and MSN are the attributes introduced by Spam. This attribute should be widely used at present. Therefore, many mainstream blogs and forums are using this tag to reduce those spam posts so that search engines are not affected by these links. If a blog has spam comments: <a href = "URL"> Top </a>; nofollow is performed in the following operations: <a href = "URL" rel = "nofollow"> irrigation </a> and other operations to avoid spam links. Now we see many celebrity blogs or popular news, first, because these sites have restrictions on advertising, and on the other hand, people use the nofollow label, which means that our webmasters will not be able to follow up on posts much, so now, there are still fewer and fewer posts and links to read these blogs or things. Some of them are advertisement-oriented, rather than our webmasters and friends.
