When doing SEO optimization, in addition to some optimization techniques, you should also use some tags appropriately so that the website can develop well. Today, let’s talk about the use of the nofollow tag. Where is the nofollow tag applicable?

Li Yuan Introduction: Where is the nofollow tag applicable?

In SEO optimization , the nofollow tag is used to indicate that the current hyperlink does not affect the search engine's index. To put it more intuitively, for example, there is a URL link to another website on the editor's blog, but the editor does not want to pass the URL for this link. At this time, the editor adds "rel="nofollow"" to the tag of this hyperlink. In this way, when the search engine spider crawls to this line of hyperlinks, it will not continue to crawl. The purpose of doing this is to minimize the impact of spam links on this website.

The official search engine researcher once said: "The meaning of this nofollow tag is to tell the current search engine spider that this link is not edited by the administrator himself, and this link is not a vote of confidence. When the search engine sees this tag, it will reduce or completely cancel the weight of the link."

Moreover, it is certain that the administrator of Baidu Webmaster Club has also given the final answer: "Baidu search engine now absolutely supports the nofollow tag. For links with nofollow tags, the search engine will completely ignore most of its effects."

For a novice learning SEO optimization, this concept may be a little difficult to understand and digest. Below, the editor will make further analysis based on specific usage scenarios to deepen the impression and understanding of memory.

Okay, next, I will talk about where this nofollow tag is applicable.

1. Add nofollow tags to interactive features on the website

Many times, when others visit our website, in order to add a slightly higher-quality external link to their own website, they often choose to leave a message and add their own website link in the message content. According to the PR (weight) theory, the PR of each website's page is fixed. The more links this page exports, the more the PR level of this page will be diluted. However, if a nofollow tag is added to these hyperlinks, the search engine will automatically ignore the impact of this link. Adding this nofollow tag on the message board can avoid this situation.

2. Add nofollow tags to the ad links on your website

When your website has a certain amount of traffic, someone will definitely buy advertising space on the website, because the other party has paid a certain amount of money, and the other party’s purpose is just to let people browsing our website see the advertisement and then click on the other party’s link. Therefore, we don’t need to pass PR to the other party’s link. At this time, we can add a nofollow tag to the link.

3. Control the PR transmission of your own website

This is the point that is most easily overlooked by many SEO optimizers. Not only novice friends, but also some friends who have been doing SEO optimization for a long time tend to overlook this problem. The PR of each page of the same website is different. For example, many of our keywords are optimized on the homepage, but there are often many links on the homepage, perhaps some "legal statement", "copyright statement", "download statement" and other similar page links. These links have no practical effect on the content construction of the entire website. These contents are just a kind of "website description" and have no meaning for SEO optimization. We really don’t need to pass PR to these pages. Then, we can add a nofollow tag to such pages, so that the PR of the entire website will not be passed to such pages that have no SEO optimization significance.

Where does the nofollow tag apply? In general, this tag tells search engines not to crawl pages that you don’t want to be included, such as website user login pages, otherwise the privacy of many users will not be protected. At the same time, the reasonable use of the nofollow tag can allow the website to concentrate authority on a certain page, allowing the weight and ranking of this page to quickly increase.
