Attribute ‘rel=nofollow’

Filed under: Articles

rel=”nofollow”, is said to be the next biggest thing to be used by shady webmasters engaging in reciprocal link exchanges. This attribute was introduced by Google as a means to prevent the problem of comment spamming in weblogs, also called “Blogs”, and it looks to be adopted by all other major search engines such as Yahoo! and MSN.

“rel” is an attribute, not a tag

rel=”nofollow” has been inaccurately called a HTML tag. It is in fact an attribute that can be added to HTML tags, similar to adding the attribute “width” to HTML tags such as <IMG> or <TABLE>. The attribute rel=”nofollow” is used on individual anchor tags <A> for links.

Purpose of rel=”nofollow”

Any link with this attribute will indicate to search engine robots that the landing page may not be approved by the web site listing this link and therefore the link will not contribute to the link popularity or ranking of the landing page.

Example link using rel=”nofollow”

An example of the use of this attribute in a link is displayed below. The resulting link, while still visible to visitors, will not contribute to Google’s link popularity, PageRank or search engine ranking (not that they really need any).

HTML code: <a href="http://www.google.com" rel="nofollow">Google Search</a>

Resulting link: Google Search

Impact on link exchanges

While this attribute is clearly beneficial, especially for preventing spammers from abusing Blogs, guestbooks and other public areas where comments can be submitted, one of the concerning consequences is shady webmasters using it for the links on their links pages and directories. A link using the attribute rel=”nofollow” is not completely worthless, visitors can still come to your web site through this link, however you will be losing out when it comes to link popularity and search engine rankings.

Another possible abuse of rel=nofollow is the use of this attribute applied to the link pointing to the links page or directory. By applying rel=nofollow in this way, the outgoing links on the links page appears valid, however, because the links page is not “approved” by the page linking to it, the links page will not receive PageRank or link popularity. Hence a link on such a page would not pass on any benefits in terms of link popularity and search engine rankings.

  1. It feels as if this attribute is throwing the baby out with the bath water. Certainly, as a blog owner, I have no desire to have my blog filled with comments from spammers.

  2. My main concern is that you can’t guarantee every page of your website will be included in the SERPs. Considering I’m constantly adding new products to my company’s website, I need to be sure that customers can find them as soon as possible.http://www.seoptimizerz.com

  3. It is still a debate whether NOFOLLOW links are useless. Some people still believe that they are beneficial for Link Popularity but do not pass any PR.

  4. if all search engines are supporting the rel=nofollow why is that yahoo still considers nofollow links as inbound links?

    tried using site explorer and tried looking to our competitors inbound links and in my shock found thousands of inbound links from blogs, and what irks me is all of their comments are spam!

  9. Can someone tell me how the nofollow is added to a link, and not anchor text? Say I am linking to a page, and want certain links to be nofollow and not all on the page. How do I add the full code when creating anchor text?

    Many thanks

  10. […] Use the rel=nofollow tag. This tag will tell Google that the page you are linking to has no value. The search engines may index the page you are linking to, but will not pass any PageRankĀ® or page reputation. You will want to use this on a page that has no importance i.e. contact us page, SERPs, about us page etc these are pages that probably dont make you money, so why have them rank.

  13. PR does not come from backlinks. Not all of it anyway.
    I have many sites that are Pr4, yet have 2 backlinks.

    I also have many sites in the number one spot, out ranking high PR sites and yet are pr1’s.

    In the end social media wins. Enjoy your rank while you can, as it will show differetn results for each person geographically.

  15. […] Instead, just check if the website as a whole has a high PR. If it does, you can get link juice from placing a link on the inner page. But remember, the link must be DoFollow. A lot of websites are now shifting towards the NoFollow attribute, because of all the widespread spam out there. […]

  27. Nofollow is being used more and more as a default method.

    If every webmaster use nofollow on every out going link, where would that leave google.

    Google might hurt themselves by having no links to follow.

  29. Although most webmaster believe no-follow links are useless, there has been several research around, and if I remember right, some folks from SeoBook have done a test by building a few thousands of sites with a common typo word that was not present in the target page and neither relevant.

    It seems that no-follow links still pass some juice or at least help ranks with some keywords. I personally judge the whole concept of PR obsolete anyways, has I have encountered several domains that were fairly aged and some with literally hundreds of thousands of NATURAL backlinks amongst them enormous quantities of PR5= links to have pretty low PR.

    The links still have a high value for rankings, but the PR concept is totally obsolete, and as far as I have personally studied, Google is now shifting to a concept of categories, not shown to the common eye, where it weights the PR by the type of links. I have several examples to back my assumptions.

  30. I agree! most websites even if they use nofollow LINK they do give page popularity to the linked page.

    However, Google is the main search engine for all the webmasters and I am sure everyone would like to see their site coming on top!

  33. The “rel=nofollow” is an attribute to “a” tag. It is very useful if you want to keep away spammers from your site or blog. But I think, making your site a “dofollow” site and inviting spammers to your site will produce traffic for your site.

  42. I see multiple versions of rel=”nofollow” showing up on websites. Quotes, no quotes, additional words added, etc. Are all the following valid ?:

    rel=nofollow
    rel=”me nofollow”

    I thought the only valid way to write this was:

    rel=”nofollow”

  51. Although I can understand the relation and purpose of the attribute rel=”no follow”, it also noted that their is no guarantee that this method will help protect a blogger who produces all his own content. I am still in the middle on a decision to utilize, but will continue researching considering content like yours. Thanx great info.
