What is nofollow? What does nofollow mean?

Many friends who are engaged in website SEO optimization often ask, why does my website stay on the third or fourth page and never go up? Can the teacher help me take a look? Is there any way? I have made friendly links and also posted external links. The competition for this keyword is not very high. Why can’t I get up there? Following the steps of website optimization, I checked one by one and found that nofollow was not done, which dispersed a lot of weight to useless links. After the problem was pointed out, the website ranking reached the homepage within a few days. Some people may ask, what is nofollow? What does nofollow mean?

1. What is nofollow? What does nofollow mean?

nofollow is an attribute value of the a tag in HTML pages. The meaning of this tag is to tell search engines "don't follow the links on this page or don't follow this specific link."

nofollow is the attribute value of the a tag in the HTML page. Its appearance provides a way for webmasters to tell search engines "don't follow the links on this page" or "don't follow this specific link." The purpose of this tag is to tell search engines that this link is not trusted by the author, so this link is not a vote of confidence.

The nofollow tag is an "anti-spam link" tag pioneered by Google and widely supported by major search engines such as Baidu and Yahoo. The purpose of the nofollow tag is to instruct search engines not to track (i.e. crawl) any outbound links on web pages with the nofollow attribute, so as to reduce the scattered website weight caused by spam links!

Simply put, if there is a link on web page A pointing to web page B, but web page A adds the rel="nofollow" annotation to this link, the search engine will not count web page A as a backlink to web page B. When search engines see this tag, they may reduce or completely cancel the link's voting weight.

2. So how do website SEO optimizers use "Nofollow"? Which links are spam links?

• 1. For example, many corporate websites have many columns (company profile, contact us), etc. These columns should be added with nofollow to avoid the loss of weight.

The website links to Baidu, the Ministry of Industry and Information Technology, or a company that makes websites for free (some companies do this). In this case, we need to do a nofollow. There is no need to waste the weight and increase their weight in vain.

2. If the website links to Baidu, the Ministry of Industry and Information Technology or well-known websites for free, should we also add "Nofollow"? Many webmasters don’t know that if your website does not use the "Nofollow" tag, then for the spiders you have voted for them.

3. Friends who are on a blog site will notice that there is a message function at the bottom of the site. For the webmaster, we don’t know who left the message or whether it is an advertising link. At this time, the message board system will automatically implement the nofollow plug-in to block the link, so the search engine will not track the link on the message board. Of course, there are some systems that do not do this automatically.

3. How to write a nofollow tag? Where to add nofollow tag? rel=”nofollow”

• 1. Write "nofollow" in the meta tag on the web page to tell the search engine not to crawl all external and internal links on the web page.

For example: <meta name="robots" content="nofollow" /> Before applying nofollow to each link

2. Put "nofollow" in the hyperlink to tell search engines not to crawl specific links.

For example: <a href="http://www.yunmajp.com" rel="nofollow" >SEO blog</a>

3. Allow search engines to index your web pages, but prohibit them from indexing the images on the web pages.

In a word, use the nofollow tag flexibly and don't let the weight of your site be wasted. At the same time, when you exchange links with friends, you should also pay attention to whether the other party's site uses a large number of nofollow tags. If it is useful, you should pay attention when exchanging and see where the nofollow tag is used. If it is Baidu, payment tools, etc., then you can rest assured. If it is something else, you need to investigate more. Take a close look at your nofollow to see if it’s done!
