Novice webmaster Nofollow label should first understand six questions

Nofollow label I believe we are no stranger to, if webmasters want to block some of the content on the site, you can borrow the Nofollow label tells search engines this place does not need to crawl, and then integrate site weight. But it is such a frequently used auxiliary label, we still often have doubts in the minds, once these problems can not be resolved in time, it is bound to webmaster friends (especially the novice webmaster) website optimization has a great negative effect . Therefore, I would like to share with you some thoughts I have in this regard today. I hope this will help you to establish a correct understanding.

Does it matter if Nofollow tags join search engine time?

Many webmasters will simply think that adding a Nofollow tag to your web site will save you time and let search engines crawl other content, so newbie webmasters deliberately set up a Nofollow tag in an effort to increase so-called site inventory. I will not say that this approach is wrong, only quoted Baidu Guide to a guideline, "for Nofollow do not give weight," we see this sentence tired? It is that Baidu just does not give the weight of the link under Nofollow But will still be included, so saving time is purely nonsense. If your site in a period of time increased a lot of coverage, it must be other work such as foreign chain construction or content to do well, and Nofollow label does not matter, in fact, the reason why search engines do not favor Nofollow is Because most of this content is worthless, the spiders will increase the period of access to this part of content as time passes, thus creating a false impression that everyone will not be included.

Nofollow label removal of duplicate links there is no real effect?

Many friends think that since the Nofollow tag tells search engines what to crawl and what to crawl, why not use the Nofollow tag to shield some duplicate links and save some crawl time. Of course, this approach is not harmful, but it also has a significant impact on the website. However, the overall effect is very general because adding the Nofollow label to my own experience does not save much time as we imagine, because Baidu webmaster guide made it clear that the spider will crawl the site after the first link, repeated and will not give the weight, and only record the effect, say the spider remove duplicate links, which is a basic Function, because now more webmasters are grassroots webmasters, SEO knowledge is not much, if webmasters want to remove the duplicate links will be added Nofollow label, it also spiders do. So in order to save time and use Nofollow label removal of repetitive links is simply superfluous.

Use Nofollow tab to control the internal weight OK?

When we know Nofollow label can shield unnecessary links, and then integrate site weight, there will be some webmasters crooked mind, want to use Nofollow tab to control the weight of their site, the general approach is to use Nofollow webmaster label Shielding a lot of internal links within the page, but this can really focus on the page weight? Obviously not so simple, first of all, I would like to give you a point that, Nofollow label is the main external, its role In the removal of some spam or no value outside the chain, if used to control the weight of the page can be a little tricky. Because when we want to shield the inner part of the link, the integration of the home page weight, whether we think there is a place we need to pay attention to, that is our friendship link area, the role of exchange friends is the weight of mutual delivery, when we put Imagine the weights together, it will be dispersed to the Friends of the chain? Clearly none of us can guarantee, and none of us will be willing to be hard-wired links to others, and also said that the internal link shielding More or less will also affect the included pages, in short, the use of Nofollow label control page weight can only be their own wishful thinking, the actual value of the operation is not large.

Are there any conflicts between using robots.txt and Nofollow meta tags?

Friends of webmaster friends all know robots.txt file and nofollow labels have a common role, that is, guide the spider to crawl the contents of the web site, for those who do not want to be presented to the spider can be masked, of course, this time there will be webmaster friend asked , Robots.txt file and nofollow label at the same time will not have a negative impact on site optimization, in fact, does not, because there is a "principle" in the search engine's algorithm, and that is who's more restrictive, Observe which, according to this point, the robots.txt file is obviously stronger than the nofollow label, for a very simple example, when your robots.txt file shield a page, the spider will be detoured directly, and Using the nofollow tag, the spider will, as I said before, the spider will include but will not give weight, so you do not have to worry about obots.txt and the nofollow meta tag conflict.

Embedding Nofollow tags in outer chains can affect their physical properties?

Often, Google does not keep track of these sites, which Google does not send PageRank or location text through these links. Essentially, the use of nofollow prevents us from crawling the page to which the target link points. However, if other sites link to these landing pages and are not using nofollow, or the URLs for those pages are included in the Sitemap submitted to Google, the pages may still appear in the index. Also note that other search engines may treat nofollow slightly differently from ours.

- From Lo Songsong blog

I've got the answer to this question in the blog of Professor Lo Songsong before, because from the above text we can clearly see that PR will not be delivered in Google's opinion, but it will not be passed and will not be affected To the site ranking and other factors, more importantly, even embedded nofollow tags, we can also come to a website through this html tag, in full compliance with the physical role of the chain.

Nofollow label webmaster means to optimize the site, can it become a means of cheating?

Where there is optimization, where there will be cheating, this sentence is nothing wrong, when we all know Nofollow label can shield links, set the site weight, then some webmasters will use this to cheat. The most common is that some webmasters without moral amount to do tricks on the links, add rel = "nofollow" in the link tag, in order to fool the links of others without losing their own weight, but fortunately now the webmaster Tools can detect this practice, but once the owners Cheyou station cheats to know, then the inevitable is to get rid of links and mutual "attack", there is no need. Another situation is that webmasters use Nofollow tags to add more links to nofollow tags to other pages in the site to increase website weight, but it is not appropriate for webmasters to add all the exported links to the Nofollow tags. Because this will make the search engine mistakenly believe that your site deliberately optimize the external links and lead to penalties, more importantly, the search engines for all pages of a link to export whether or not this label will give weight transfer, then add a nofollow tag The link will be given the weight, but will not be passed, then the page of the entire weight virtually evaporated some or all. So Nofollow label is not a means of cheating, should be rational understanding.

Compared with the use of Nofollow label optimization of the site, as we first Nofollow label for a rational understanding, granted by the fish as granted to fish, we grasp the correct understanding, but will make their own optimization process more smoothly .
