How to Use the Google NOFOLLOW Attribute in SEO
Nofollow Attribute in 2019: Good or Bad for SEO?
by Dr. William Sen
In 2005, Google introduced the nofollow attribute. The original idea behind it was to allow websites to link to external sources while giving Google the signal not to trust them. As a result, Google would not follow the link and ignore it. However, this feature has been abused so often that Google has been treating the nofollow attribute differently since 2015.
It’s the same with all things in SEO: If it’s abused too many times by too many SEOs, Google will act on it. This was no different with with the nofollow attribute. Here are the key features of how nofollow is used and how Google will respond to your nofollow attributes in 2019.
Some website owners have set their CMS in a way where almost all outbound links have the nofollow attribute. In this case, Google will assume the attribute has been abused in order no to pass the site’s trust to other sources. Accordingly, Google will check if these sources are in fact untrustworthy or not.
The algorithm works according to the following criteria: It checks if other website administrators also set a nofollow to these links. If the answer is negative, Google will conclude that the nofollow attributes serves only one purpose, namely to send Google a false signal to create an SEO advantage. SEMRush reports in their article “Are Nofollow Links Actually Good For SEO?” that the quota of nofollow attributes should be not more than 20-40% for a website.
Only a Few Links Have Dofollow
If website owners only put a dofollow on a few links and everything else has a nofollow, your website will be flagged by Google. Such patterns are found on sites that usually sell links, mostly hidden in blogs and other forms of articles. Selling backlinks is a violation of Google’s Guidelines. Google has been using sophisticated techniques to identify artificial link farms and purchased links since the Florida Update in 2003.
The simplest method for Google to find out whether you are running a backlinks strategy is to check of the historical development of backlinks. Imagine that almost from one day to another, your website suddenly gets a lot of backlinks — and all that without reason such as having scored with a viral article — Google will raise the flag. It’s very easy for Google to find out automatically that that a backlink strategy had been initiated. I wrote about this: Building Backlinks with Google in 2019.
A manual action by Google is to be expected in such cases which can lead up to 90% traffic loss and more. The linked site is also negatively affected: Now that Google knows that articles with links are often bought, articles with dofollow links no longer get the rank they would normally receive.
How to Use Nofollow Properly
The two most important principles are relevance and trustworthiness. If the link is relevant to the article or content and the source is to be trusted, then the nofollow attribute should not be used.
Here’s an example: Above, I referred to the article written by SEMRush. If I had linked to the article using a nofollow attribute, I would have given Google the wrong signal that the link was untrustworthy. But Google would know that SEMRush is one of the most trusted sources on the web and therefore would identify my nofollow as abusive. Also, the article from SEMRush is relevant because it mentions the same topic as I do in this article. Google recognizes the relevancy between the two articles due to their Topic Detection Algorithms. A nofollow attribute would not have made sense here.
It is also true in 2019 that with each additional link, the trust is inherited from its own website to the linking source. This means that your own trust decreases with every link — Google’s PageRank Algorithm is still valid today in 2019.
So, what if you do not want to pass on the trust?
If you are stingy and do not want to give a trust to another web source, you should not insert a link at all, rather than using the nofollow attribute.
Using this example above you can see that no link has been placed when referring to the SEMRush article. This way, this article can’t be flagged by Google as far as it concerns backlinking: Google does not pay attention to the correct or incorrect use of a nofollow if you don’t use links at all. The disadvantage in this case is the user experience. If you don’t use links, you are taking away convenience.
Not putting nofollow at all is just as damaging as putting nofollows all the time on links.
The days are over when Nofollow was the perfect solution not to pass on the SEO trust: Google has already responded to this with updates since 2015.
The basic principle of the Internet and the breeding ground for search engines are links. It was already clear that Google would put an end to the nofollow game when the introduction of the nofollow attribute raised critical voices. However, it took 10 years for nofollow to be abused by a critical mass of users and websites for Google to respond with an update.
In my article “Wikipedia SEO: The Invisible Power Game” I wrote that Wikipedia uses the nofollow attribute in all their articles. Back then in 2013, Wikipedia didn’t have to fear any consequences from Google for their abuse of the nofollow attribute. As a result, millions of articles on Wikipedia were ranked first on Google.
Due to the new update, Google has punished even Wikipedia for their nofollow links. Anyone wondering why Wikipedia with their topics and terms no longer occupy the higher ranks on Google would now know better: Wikipedia has been abusing the nofollow to this day.
Due to the size of Wikipedia, this fact may be irrelevant for them. Like many portals that have grown into giants, one or the other lack of SEO strategy does not matter anymore. However, if your website ist not on of the top 100 websites in the Internet, you cannot afford to use the nofollow attribute incorrectly.
