Importance of rel nofollow attribute

Filled under: ,

Method used on the Internet to prevent transmitting links PageRank value to other pages, and use it to prevent spam and evaporation of PageRank, as knowing the links with this attribute. DoFollow Movement against the unfairness of this system.

The rel "nofollow" attribute is very controversial in the Internet community, has its followers, who consider it useful and necessary to their jobs and detractors who are completely against it, considering it an unjust and discriminatory towards content publishers, especially those with fewer resources.

What is the rel "nofollow"?

An attribute is a specification that defines the property of an element, in this case is used Nofollow links, aims to tell the search engines that scan the source code of the pages, that the link must not transmit any value that has that page. On the Internet links have always represented a vote or recommendation from one page to another, in this case to have the Nofollow, no value above.
Attribute rel "nofollow" began to be implemented in practice some years ago by Google, other search engines are ignored if they use it. 
Aimed to put a barrier to spam, the Internet called cancer, very common in forums, blogs and other Internet sites participation. Currently used as a powerful tool to manipulate and administered according to the convenience and interest of the owners of pages and sites, how they should flow PageRank, or the value thereof which has been assigned by Google.

How to insert HTML code in the rel "nofollow"
The rel nofollow attribute is used in HTML code as follows:
<a rel="nofollow" href="http://wbupdates.com/"> Link </ a>
You can also use the HEAD area or header, using the label Robots:
Content="no name="robots" /> <meta follow"
This is the least used because in this way all the links on the page have the same value, unless particularly specified.

Using rel nofollow to prevent evaporation of PageRank

The rel nofollow attribute can be used to block the links or links that lead to external sites, when deemed not to be sharing the value of our website to which we refer. 
Words to prevent the PageRank that currently has or may be our future, flow through the external link, what is known as PageRank evaporation, Especially useful when a page has many external links.
According to Google, as he explains in his blog Matt Cutts: PageRank sculpting (Handling PageRank), do not use this attribute on internal links of our site, allow flow naturally for the same, and bringing no positive effect to block our own pages, IE not intentionally favor a ranking of a particular page blocking others.

How to detect the rel nofollow in the links of the pages

The easiest way to find and detect when a website links have rel nofollow, is to use a bookmarklet.
A bookmarklet is just a link that contains a portion of JavaScript code, which can be available in the bookmarks bar or web browser bookmarks. When loading the website in which we want to know the attribute of the links and give a click on the bookmarklet button, automatically links having rel "nofollow" highlighted with yellow background, the ties that do not have it show the pink background.

Bookmarklet to know the attribute that have links on a page

To make it available, drag the button to the left to the bookmark bar of your browser. If you are using Internet Explorer gives a right click on it and from the menu that appears choose "Add to Favorites", select "Favorites Bar". If you give a click on the bookmarklet to try it on this page, check that the link leads to the blog of Matt Cutts is set to "nofollow" naturally does not need my input, your blogs PageRank 8.

Sites, blogs and pages Do-Follow movement in Internet

There is now a growing movement of webmasters, webmasters, blogger and people in general who are in favor of making the links in the comments in Dofollows, increasing the participation and integration of visitors and participants discussions effectively, and contribute to the free flow of information on the Internet. Employing the nofollow attribute alone in his original goal, so their use should be limited to blocking spam on blogs. sites for this movement known as pages and blogs DoFollow (DoFollow is the default attribute of links) is amazing and disappointing misuse of the nofollow value at any website, especially in the important sites and powerful who for various reasons are well-ranked by Google , but often that value is not fully justified. Many thought should not be used at all the nofollow attribute in the following cases:
  • Comments on blogs, forums, and Internet sites share in the comments of those involved bring any value to the page on which they are inserted.
  • Links and links to external sites that we insert into our pages with the objective references that are useful to the user and which logically will add value to it.
  • article directories that the reason for its existence are the articles written by users, however most of them absurd way down the rel nofollow in the content and links pointing to the website of the author, solely for the purpose of no benefit stingy with the fluidity of PageRank that can reach that page in the future. Sites that work with data, information and content provided by the users and are reluctant to provide a valid link to turn. One example among thousands: YouTube.
How to know pages and Do-Follow Blogs on the Internet?

On the blog: DoFollow Blog List: (http://followlist.com/) keep records that appear on blogs that do not use the nofollow rel attribute in the regularly updated list can be searched by subject according the interest of each person. If you have a blog in Wordpress, possibly the links in your comments are nofollows, check it, modify it and join our movement, in the page that you can meet and make appointment, course in a blog by disabling the rel no follow the link, it is imperative that the comments are moderated manually, it is not correct that spammers take advantage of this situation to win some links easily, using nofollow on this site.

The links in this site that refer to external resources, useful and interesting to the user, they are not inserted rel "nofollow", we think it best not to put a link to have one recommending block a site and hypocritically,
course there are exceptions, one can understand perfectly the "nofollow" to link to Matt Cutts, also employ reciprocity with justification, that the site does not use rel nofollow in the links we suggest, we can not employ us.

The Penguin and the links on the websites

After the release of Google's algorithm Penguin and subsequent updates, Internet is not the same, not for users, whether for the content we publish. 's no use to use the rel = nofollow, to recommend a site that we think interesting and useful if the page look bad by Google for some reason, the link will affect us, our page and throughout our site. That way we can be penalized for any link innocent, without interest whatsoever for us, course that only affects us if we rely on Google for traffic to our sites and if we are not strong, which applies to the vast majority.

What is the cause of Google penalty?

The cause is the fight against web spam Google holding the job and eliminate the results of searches, low quality, copying, plagiarism and repetition. For those who publish content of interest, will be beneficial in the long term these measures, but we understand that we gradually lose the true essence of Internet, now everyone is afraid to insert any link on a website, others write like crazy demanding webmasters, who previously begged for a link, now because remove them. Personally we tested firsthand, losing position because quite a few links to sites apparently poorly regarded by Google, unfortunately we had no choice but to remove them, has been somewhat painful for me, we have to admit it, but by a great responsibility in my private life, my family is fed income provides my site. conclusions, to publish articles in our pages or any links to sites that we consider interesting and valuable, we must wait a little, we will have to wait algorithms of search engines are smarter and know the difference that our purpose is not to spam web, our only purpose is to make the net wider and richer, but more democratic. I'll have to wait .... if that ever comes.
