What is the nofollow label command?
When a webmaster uses the nofollow tag, tell the search engine "do not track links on this page" or "do not track this particular link." That's what we always say. Nofollow does not pass this link.
What are the forms of nofollow?
Page-level META Tags: I believe you see a website code, there is a meta tag, for example, "description, Title" will use META tags, then we can also use meta tags to write nofollow tags, that is to tell the search engine is not the link on the page to catch. The link to the entire page does not pass the weight. The wording is as follows:
Link-level properties: Then there are a number of individual links we do not need search engines to chase, such as your site appears Taobao link, then we need to prohibit this is the Taobao link instead of the entire page link, so this time we need link level attributes to control the nofollow tag. The wording is as follows:

When to use the nofollow tag
Untrustworthy content: As we do SEO blog, a lot of message board has a left a link to the message board Plug-ins, such as more say message board plug-ins, then this time, we do not know who is the following to your website message, it is likely to publish spam ads, or to leave other untrustworthy links, This time more say the message board system will automatically implement Nofollow plug-in screen link, so the link search engine on the message board will not catch up with its link.
Paid Links: The paid link here is not paid links, if it is a paid friendship link you also add nofollow no one to buy your, then the paid link here refers to the advertising link, when our site is hanging ads, we can use nofollow to screen each other's advertising links, Don't let search engines crawl, but ads can still show!
Crawl by priority: For example, many Web sites have login registration pages, then this login registration page in the user's perspective to consider, there is demand, but for search engines, these login page is meaningless, because users will not go to Baidu search "login" The word any came to your site, And this link must be shown on the homepage, because the user needs to log in to register, then we need to use nofollow to screen this link.
The role of nofollow for SEO optimization
Prevention of spam sites: such as our blog is so, in order to prevent the point of spam links, then the message board and Comment box will be used to nofollow to screen these links, this time even if there is a discordant link, we are also prohibited search engine crawling, timely other site problems, We will not be affected.
Weight concentration: Of course, not only for shielding outside the chain of garbage, at the same time we can focus on the weight of the site, a very simple analogy, when a cake two people eat, will be a lot, if 20 people eat, then maybe a person can only eat a little bit. Then our site is also so, when the weight of the site is not passed to others to get the site, then your site's weight is relatively high!
What's the difference between nofollow and robots?
Many people don't know the difference between robots.txt and nofollow, in fact, they are not the same concept, timely are prohibited search engine crawl, but for the search engine is not the same, robots are prohibited search engines included in this page, when we have a file inside the ban on a certain page, or search engine included its page, then you can write in Robots folder inside, and nofollow just forbids search engines to crawl a link on a page. So the difference is different. Then we said in front of, login page, we can through the Nofollow screen homepage on the page link, but can not prohibit the search engine included its page, then we can use the Robots screen this page, do not let search engine included this spam page!
