Nofollow is Google launched in 05, the role of the definition is used to tell the search engine spiders add nofollow attributes of the link do not have to crawl, Google launched the Nofllow attribute is nothing more than to combat the increasingly rampant spam mass behavior. Later we found in the optimization process of its site optimization benefits, began to use this property for SEO technology.

Forums or blog site People should be aware that we can use the nofollow attribute to deal with the effect of unhealthy comments on garbage. But a lot of optimization staff will have a misunderstanding, that the use of this tag can be very good to save the weight of the site does not lose. And obviously this idea violates the search engine to launch the Nofollow label's real intention, the search engine does not want to let the optimization personnel can through this attribute to conveniently manipulate the weight the allocation, finally affects the normal rank. When we get a good look at Google's intention to introduce this attribute, we will understand the true meaning of this attribute. In fact, is to tell the search engine spider What connection is meaningless, what links do not crawl. At the same time we can use this attribute to see sweep search engine on the site of those meaningless pages crawling, but a search engine crawling quality of higher pages, improve the site in the search engine eye of the overall quality.

The overall content of the site page is an important indicator of optimization, especially for those large sites, search engine spiders can not be in a day to all the pages are crawling, if the search engine spiders just stay in some of the quality of low or invalid pages, then the overall quality of the site will have an impact. In the following article, the author will take Phpwind (the current mainstream PHP forum system, the following PW abbreviated) forum as an example, analysis of how to try Nofollow properties to achieve its true meaning.

One: Tell search engine spiders do not crawl meaningless links

Which area of the site is relatively high weight? is undoubtedly the top of the site, appear in the top of the homepage of the link, is obviously able to get a high weight of the link, nature can also get a good grab, pw to "find the password", "Number of posts Today", "User name" Links have been added to the nofollow properties, and for these pages, the user root will not search the search engine, the search engine to include these pages is not necessary.

Two: Reduce the excessive crawling crawl to some low quality pages

We also look at the PW forum page, like "Post" link button General page will have two, PW choose to use nofollow attribute to remove one of the links, this approach is obviously to reduce the quality of some of the pages of the excessive crawling crawl, so that search engine spiders have more "energy" To crawl forum posts.

Here choose to take PW as an example, because I think PW for nofollow use just right, this is PW can be so friendly to search engine one of the main reasons. On this site as long as we master the use of nofollow properties, then we can use it to improve the overall site page of the total collection, when included up, the flow of nature is not a big problem.

Summary, for the use of nofollow attributes, we clearly understand its importance to our optimization, but we need to clearly understand the true meaning of its use to better serve our optimization.
