Then we face by many stationmaster discard of nofollow label, how let its play advantage outweigh the effect of the disadvantage, help enhance the optimization effect of the site? Today I talk about how to use the nofollow tag to improve the site's optimization effect.

　　Definition of nofollow label

In Baidu Encyclopedia Nofollow label is defined as telling the search engine "do not track the link on this page" or "do not track this particular link." The simple explanation is that when we do not want to be searched for the link to crawl links, then you can link the links in the link to add nofollow tag to tell the search cited this section of the content can not crawl crawl. If we do not want a link on the page is crawling crawl, you can add a nofollow tag on a link to tell the search link can give up tracking. Nofollow tags in the optimization is a kind of refusal to crawl spiders meaning.

How to use the nofollow tag to promote site optimization effects

In the site optimization, nofollow label has been defined as a link to cheat code, we have to find the nofollow tag is very easy, first open the source code of the site, and then by looking for nofollow this keyword, Moreover is to see which place has the nofollow label existence, if is follows in the Friendship link section The back, that such friendship link does not exchange, after all nofollow the label is tells the search to lead this link all page links can not be crawled crawls, This means that the weight cannot be passed. The equivalent of casting a vote to give up the ticket. We can use the nofollow tag to improve the site optimization effect.

First analysis of the site where the link is not to search for the crawling, in general, such as advertising cooperation, website help, contact us, complaints and suggestions such as these pages can be added nofollow tags, because these pages even if the search is not to grasp the site's optimization to provide any help, It's not bad if it doesn't.

Second, in each of their own think do not need to search for the link to crawl to add a nofollow tag, writing can be a single write, such as we in the blog optimization, do not want to let search leads to crawl some comments message section, then we can add a nofollow tag in this section, written as follows:< A href= "http://www.****.com/guanshi/" rel= "nofollow" > Irrigation </a>. So when the search leads to see nofollow tag this page code will understand, this page is not crawling crawl, can also be understood as the content of this page is not high quality.

You can also add a nofollow tag to the content part of the call, for example, we often call Youku video, but do not want to let search lead along this link to the Youku target station, you can add a nofollow tag on the call to tell the search link does not exist crawling feasibility. This can enrich their site content, but also do not worry because the use of the content of other sites and lead to loss of weight site.

The last use of nofollow tag aggregation site weights, we can use nofollow tags in the head to emphasize the search can grasp the range, such as we do not need to search the home page to crawl all the links to the outside, then you can use the head of the home page nofollow tag, writing methods as follows: <meta name= "Robots" content= "nofollow"/> So, search lead Zhi know, all with their own site is not the same as the chain through will not be crawled, in fact, this is the most insidious way to cheat links, After all, even if the link does not add nofollow tag, and in the header has been stressed that all the external links are not crawled, so the friendship link is meaningless. But for the owners of conscience, this method can not be easily used, after all, loss of a friend chain does not matter, loss of integrity that loss is very large. In fact, as long as some meaningless pages using nofollow tags to screen, for the improvement of the site's optimization effect does have a very good effect.

Nofollow label label is not so useless, at the same time is not the best tool to cheat links, and sometimes reasonable use of nofollow tags to block some meaningless links or pages, the effect is very good, After all, Google and Baidu for nofollow label priority role can be very good support. So, clever use nofollow tag optimization site can really let the site optimization effect to a new level.
