The nofollow tag should be familiar to webmasters. I also encountered such a problem today. A website that exchanged links with my website added this tag in front of my domain name. Today I accidentally checked the friendly links and found that a website had a nofollow tag on my official website. After seeing this result, I would like to share my knowledge on this topic with the majority of webmasters.
Webmasters all know that a very important factor in Google's evaluation of the PR value of a website is from friendly links, that is, reciprocal links. However, some webmasters, in order to gain nothing, have come up with the idea of letting others serve them. The way to contribute is to use the nofollow tag to export the link. So, let’s introduce what the nofollow tag is and how to use it;
Nofollow tag origin:
In order to add backlinks, SEO cheaters publish a large number of content with irrelevant links in forums and blogs. The existence of these spam links causes a certain degree of trouble for search engines to evaluate the quality of web pages. nofollow is an attribute introduced by Google, Yahoo, and MSN to deal with spam links. This attribute should be widely adopted now.
For example: If there is a link on web page A that points to web page B, but web page A adds the rel=”nofollow” mark to the link, the search engine will not count web page A as a backlink to web page B.
How to use Nofollow:
If there are spam comments on the following website:

So here’s how to do it:
Add nofollow tag:

Therefore, search engines will not include this link when calculating the PR value.
The role and conditions of use of the Nofollow tag:
At present, most blogs and website building systems have added the nofollow attribute. That is to prevent those who come over to post spam links, and the work they do is meaningless.
If you are worried about your website being infested with spam links, nofollow is a very good method. However, the nofollow tag does not mean that the search engine will not include that link, it just does not count it in the backlink factor.
Of course, everything and any effect has a negative effect, just like the function of the nofollow tag. Since the nofollow tag can prevent others from sending spam links to the website, it can also occasionally deceive webmasters who do not understand it. After exchanging friendly links, some Opportunistic people add this label. Once the webmaster understands this, he will be able to solve this problem in the future. Although this is not a new discovery, I am still willing to share it with the majority of webmasters.
