Nofollow Links

A nofollow link is a link with a nofollow attribute, these are used to prevent link juice or PageRank from passing to the page being linked to. The video tutorial below explains a little more bout what nofollow link data is within out web crawer.




What is a NoFollow Link?

Let’s first provide some background that’s helpful for understanding what the effects of nofollow links are and what they do. We all know that an internal link allows users to navigate to a new page, which is the same engine perspective. However, unlike follow links, they do not pass on authority.

Google developed an algorithm called PageRank which calculated the authority of each page on a site. Therefore, a follow link will boost the PageRank of the page being linked to. Depending on where backlinks are pointing to pages on your site, the internal links on your site will distribute that authority. A link in HTML looks like this:

<a href="">Linking Data</a>

No nofollow links looks like this:

<a href="" rel="nofollow">Nofollow Linking Data</a>

You can see that this link has the rel attribute equals “nofollow”. This is the component that determines the link as a nofollow link. ‘Nofollow’ link and will not pass on authority to the page being linked to that domain.


Why Are NoFollow Links Used

This is not the default link as it requires an additional attribute, but if you have pages such as:

  • Indexed pages
  • Disallowed pages
  • Non-canonical pages
  • Pages hidden behind a paywall
  • Pages that require as user to login


External Site Links

There are other reasons, but one of the main reasons is when linking externally, which means linking to a different domain. This is done to prevent link juice (authority) from leaking to another site. If you have social media links listed on the footer of each page of your site that could be thousands of links all leaking authority away from your site.

It is completely legitimate to link to an external site with a nofollow or a follow link, this is down to a number of factors:

  • The site is relevant and trustworthy
  • It is pertinent to the content
  • There are not so many of them they would have a negative impact
