Nofollow label believe that everyone is not unfamiliar, if the webmaster want to screen some of the content of the site, you can borrow nofollow tag to tell the search engine this place does not need to crawl, and then consolidate the weight of the site. But it is such a regular use of the auxiliary label, we often have doubts in mind, once these doubts can not be resolved in a timely manner, the Webmaster friends (especially the novice webmaster) site optimization brings a great negative effect. So today I would like to tell you a few ideas in this area, I hope to help you set up a correct understanding.

Nofollow tag and search engine crawl site time has no relationship?

Many webmaster friends will simply think that the content of the site to add nofollow tag will save time, so that the search engine to crawl other content, so there has been a novice webmaster in order to improve the so-called site collection and deliberately set the Nofollow label. I do not say this is right, only to quote Baidu Webmaster Guide A word, "for the nofollow do not give weight", this sentence we see the trick? That is, Baidu is not to give the nofollow under the weight of the link but still will be included, so save time a saying is pure nonsense. If your site in a certain period of time to collect a lot of increase, it must be other work such as the chain building or content added to do well, and nofollow label does not matter, in fact, the search engine does not favor the content of nofollow, because this part of the content is mostly worthless, Over time the spider will increase access to this part of the content of the cycle, so also give everyone caused not to be included in the illusion.

Is there a real effect to removing duplicate links with nofollow tags?

Many friends think that since nofollow tags can tell the search engine what the crawl, what should not crawl, then why not use the nofollow tag and some of the repeated links to screen, and then save a certain crawl time. Of course, this approach does not harm, the site will also cause any significant impact, but the overall effect is very general, because of my own operating experience, add nofollow label can not be as we imagine that save a lot of time, because the Baidu Webmaster Guide to say clearly, Spiders will be the site's first link to crawl after the repeated occurrence does not give weight, and only to record the role, and then the spider removed duplicate links, this is a basic function, because now more webmaster is grassroots webmaster, SEO knowledge does not know much, If stationmaster wants to eliminate duplicate link to add nofollow label, that also want Spider to do. So to save time and use the nofollow tag to remove repetitive links is simply superfluous.

Use nofollow tag to control internal weights.

When you know nofollow tags can be shielded without the necessary links, and then integrate the weight of the site, there will be a part of the webmaster moved a crooked mind, want to use nofollow tag to control the weight of their own site, The general practice is that the webmaster use nofollow tags to screen out many internal links inside the page, but do you really can focus on the site page weight? Obviously not so simple, first of all, I would like to give you a point, the Nofollow label is outside the main, Its role in the removal of some spam messages or no value of the outside chain, if used to control the page weight can be a bit unreliable. Because when you want to pass through the screen inside the page part link, integration of the weight of the home, whether think we still have a place to pay attention to, that is our friendship link area, the role of the exchange of friends is the weight of the mutual transmission, when we put the weight of the imagination together, will be dispersed to the friend chain? Obviously none of us can guarantee that, and none of us will be willing to work hard to save the links to others, and also said that the internal link to the screen will affect more or less the inclusion of the page, in short, the use of Nofollow Label control page weight can only be webmaster own wishful thinking, the actual operation value is

Is there a conflict with the robots.txt and nofollow meta tags?

Webmaster friends know that robots.txt files and nofollow tags have a common role, that is to guide spiders crawl site content, for do not want to present to spider things can be shielded, of course, this time there will be webmaster friend asked, robots.txt file and nofollow tag use will not give the site optimization brings negative impact, its This is not true, because there is a "principle" in the search engine's algorithm, that is, who is more restrictive, according to which, robots.txt files are obviously more restrictive than nofollow labels, to give a very simple example, when you robots.txt file screen a page, the spider will be a direct detour, and the use of nofollow tags, spiders will be like I said before, spiders will be included but will not give weight, so we do not have to worry about Obots There is a conflict with the. txt and nofollow meta tags.

Does embedding a nofollow label outside the chain affect its physical properties?

Typically, Google does not track these sites, that is, Google does not send PageRank or position text through these links. In essence, using nofollow prevents us from grabbing the page that the target link points to. However, if other sites link to these destination pages and do not use nofollow, or if the Web pages are contained in a site map submitted to Google, they may still appear in the index. Also note that other search engines have a slightly different approach to nofollow than we do.

--Quote from Lou Blog

I got the answer to this question in Lou's blog. Because from the above text we can clearly know, in Google's opinion, PR will not be delivered, but only will not be passed, will not affect the site rankings and other factors, more importantly, even if embedded nofollow tag, We can also use this HTML tag to come to a website that fully conforms to the physical function of the chain.

Nofollow label is webmaster optimization site means, can become cheating means?

Where there is optimization, there will be cheating, this sentence is correct, when we all know that nofollow tags can be shielded links, set the weight of the site, then some webmaster will use this to cheat. The most common is part of the lack of moral the webmaster in the links to cheat, in the link tag to add rel= "nofollow", in order to cheat other people's links, and not let their weight loss, fortunately, now webmaster Tools can detect this practice, but once the webmaster cheat method Let friends station know, Then it is necessary to undo the link and mutual "attack". There is also a situation is the webmaster use nofollow tags will add nofollow tag links more transfer to other pages in the station to increase the weight of the site, but the webmaster put all the export links are added to the nofollow tag, which is not very appropriate. Because this will make the search engine mistakenly think that your site deliberately optimize external links and lead to punishment, but more importantly, search engines for a page of all export links whether or not the label will be given the weight of the transfer, then added the nofollow tag link will also be given weight, but will not be passed, Then the overall weight of the page virtually evaporated part or all. So nofollow label is not a means of cheating, we should rational knowledge.

Compared to the use of nofollow tags to optimize the construction of the site, we should first of all to nofollow a rational understanding of the label, the award of fishing as a fish, we grasp the correct understanding, but will make their own optimization process more smoothly.
