I hope you can get something after reading this article. Let's take a look at this "what is the role and application of nofollow attributes" article.

What is the value of Nofollow attribute

Nofollow attribute was originally launched by Google search engine, but in the subsequent optimization, its role has been recognized by various search engines. At present, the mainstream Internet search engines have all supported the Nofollow attribute. Nofollow is meant to guide search engines not to track links to pages referred to by tags, so that the weights of the site can be more centralized, so that the weights will not be scattered by insignificant links.

In addition, the role of Nofollow is not only to put an end to the external chain of decentralized website weight, which is only on the one hand, but also to put an end to the internal links of diluted keywords. As an optimization tag, its role has become more and more prominent in the ranking of websites. By the margin of error, Nofollow has laid down the details of the website's success.

II. Optimal application of Nofollow

As an optimized tag, Nofollow can be used in practical application to block the outer chain of advertisements, the statistical code of websites, the links after JS calls, and the inner chain of useless keywords (such as about us, comments, viewing more... Wait for a page link). The above are commonly used techniques for white hat optimization, and if you encounter people with ulterior motives, you will also use Nofollow to shield the chain of friends in the exchange of links. In this way, the friendly link has become an one-way link, although it is more shameless, but there are still a lot of people using it.

In the page design, the message board and comments of the template are generally optimized by Nofollow, so as to prevent the website from becoming a link factory, but the optimization of internal keywords and outer chain is not in place. Such descriptions not only have no effect, but also dilute the keywords of the site, such as the number of comments and the number of visits. Therefore, we can use nofollow tags to optimize it to reduce the inner chain of useless keywords. Of course, this is a practical example. I believe there are many such things in the process of website optimization. I hope you can dig more such links and optimize them.

III. Correct and standardized Nofollow format

Although Nofollow tag plays an obvious role in optimizing the website, improper use of it, writing errors are more likely to cause the website optimization to be counterproductive, and even become the direct cause of the website being K. So, how does Nofollow write correctly?

Example 1:

Link text

Explanation: can be used to block specific external or internal links, such as website "comments, advertisements, message board URL". In general, in the optimization process, you only need to add a "rel=" nofollow attribute to the tag to complete the optimization.

Example 2:

Explanation: seeing this, I believe many friends have understood that writing nofollow in the title means forbidding search engines to grab all the outer chains. But this is very immoral, so I'm afraid no one will exchange links with you.

Example 3:

Explanation: this tag allows search engines to access all the content of this page, but does not represent all the content.
