WEBINAR: Google Penguin 4.0 is live - Real Time Penguin Insights and Outlook
Since Google made various statements following the launch of the Penguin 4.0 update, the controversy around Google Penguin 4.0 increased. Join the webinar and have Christoph C. Cemper - the founder of LinkResearchTools (LRT) and Link Detox answer all your questions.
The value of NoFollow links has often led to heated debates among online marketers and SEOs. Ever since Google Penguin has been rolled out, the risk of links has become a central question.
People often claim that links marked as NoFollows have no impact. Some SEOs still rely on former Google statements suggesting that NoFollows do not pass PageRank, taking this as “evidence” that spammy NoFollow links cannot put you at risk of a Penalty.

What are NoFollow Links?
A NoFollow tag is a way that allows webmasters to tell search engines “Don't follow links on this page" or "Don't follow this specific link." A link can have one or more rel attributes, where “rel” is short for “relationship”. These attributes help define the relationship a link has with a page that it points to.
A NoFollow link looks like this:
<a href=”http://www.example.com/” rel=”nofollow”>Link Text</a>
Such links are used in blog or forum comments in an attempt to take away the incentive for automatic link spammers to place their links there.
Interestingly enough, however, this has hardly reduced comment spamming. Well, guess why!
The debate on NoFollows is often focused on the following questions:
Let’s look at a practical case. A link from Wikipedia is more relevant as to traffic and thus more important for SEO even if the link is marked as NoFollow. Some people believe that NoFollow links pass Trust. However, this could also imply that negative Trust could be passed as a spam signal.
If your website was affected by a Google Penalty, you need to focus on the links you bought in the past and on the spam examples provided by Google. But what if there were NoFollow links among those bad, manipulative links named by Google?
Many SEOs and consultants believe that disavowing a link will simply turn it into a NoFollow. This would imply that there is no point in disavowing a NoFollow link. But what if it’s precisely those NoFollow links that are causing problems? The statement that disavowed links are “merely” turned into NoFollow links was a casual remark from Google when they gave an explanation of the Disavow Tool. However, this would mean that harmful NoFollow links cannot be made ineffective through disavowing.
From the above-mentioned presumptions, one could think that there is no need to deal with NoFollow links as they don’t imply any risk. If, however, we assume that Google’s explanation is a simplification, on the one hand, and inconsistent, on the other, investing more time in the analysis and review of NoFollow links is worthwhile.
Google’s statements on NoFollows
In general, we don't follow them. This means that Google does not transfer PageRank or anchor text across these links. Essentially, using nofollow causes us to drop the target links from our overall graph of the web.
However, the target pages may still appear in our index if other sites link to them without using nofollow, or if the URLs are submitted to Google in a Sitemap. Also, it's important to note that other search engines may handle nofollow in slightly different ways.”

On September 9, 2013 - Matt Cutts said that
typically, NoFollow links cannot hurt your site.
The fact that he used the word “typically” is an indication that NoFollow links can hurt your website in exceptional cases.
The evaluation of the answers from the Google spam team makes things even more interesting. In 2013, Google began to provide spam link examples as part of their answers in Reconsideration Requests. A total of 4,649 spam link examples for 854 domains could be collected from the period between August 16, 2013, and July 2, 2014. Precisely these links named by Google were checked with the Link Check Tool (LCT) to measure the status of the links as of July 2, 2014.
The result shows that already 27% of the links had already been removed and that 10% of the links have been turned into mentions in the meantime (meaning a domain is mentioned but not linked). About 3% of the spam links named by Google were NoFollow links, some of which have existed on article directories or press portals for years.
Below, Google provides two examples of links. The first link is an article directory that has been taken offline in the meantime. The second link leads to the relatively known press release PRNewswire.com.
It takes an SEO’s trained eye to recognize that such a “press release” is simply a piece of text stuffed with Money Keywords that has obviously only been created for SEO purposes. Online press portals have been promoting the SEO value of their publications for years, and the domain PRNEWSWIRE.COM is relatively large – but there were other providers that had e.g. no hesitation in packing their clients against thousands of articles per day on relatively useless, article-stuffed domains, taking good money of course. And things were even more extreme on “free press portals”.
This example is especially interesting because the link was a normal Follow link first and changed to a NoFollow in July 2013 only after Google announced link spamming via press portals as a violation of their guidelines. PRNewswire took action quite quickly, but many other providers reacted to the change much later. Further analysis of such cases needs to be done, but it seems obvious that the current status of an existing link does not necessarily reflect its effect on Google Penalties.
The true intention of Google
Google wants to make webmasters aware of their manipulation “attempts”, punishing the approach, not the links. And it does not seem absolutely necessary that the links are marked as Follow links. At least in some cases, it didn’t matter that links which were used massively for spamming before were changed to a NoFollow status.
We've put together a white paper explaining 9 link spam examples given by Google, where we explain them in more detail for you. The last thing you want is to build links that Google considers spam.

How the SEO community sees NoFollow Links
In July 2014 we started an open poll asking, among other questions, whether the participants believed that NoFollows can put a website’s ranking at risk or not. Slightly more than 50% of the 181 participants believed that NoFollow links can have a negative impact on their results in Google.
How we handle NoFollow Links in LinkResearchTools (LRT)
Since 2014, LinkResearchTools (LRT) supports two opinions when it comes to the risk of NoFollow links. Many users asked us for our opinion which analysis mode to use, and we always and still believe it’s very important to include NoFollow links in the analysis. Google included NoFollow links as spam examples as part of their answers to reconsideration requests.
The NoFollow evaluation is now pre-selected as the default option in Link Detox (DTOX), but you can always switch it back to ignore NoFollow links fully, also when reprocessing a report.
The difference between a Link Detox report that has the NoFollow links evaluation activated and one that ignores NoFollow links can be major. You can see below a clear example of a Link Detox report that takes NoFollow links into consideration and one that doesn't.
The domain-wide Link Detox Risk (DTOXRISK) is much higher when we choose to evaluate NoFollow links. You should remove or disavow all those NoFolow links that look spammy and have a high risk for your backlink profile. They influence the overall quality of your backlink profile. Only the fact that they are NoFollow links, does not make them risk-free.
Estimate the Link Detox Risk of your own backlink profile (including the NoFollow links) using LinkResearchTools (LRT)
Most websites have a mix of Follow and NoFollow backlinks. In some niches, it's common to have a higher percentage of NoFollow links than in others. Using Competitive Landscape Analyzer (CLA) you can analyze your competitors and see the typical Follow / NoFollow link ratios of the domains that are ranking on the first page of Google for your industry.
You should aim to have similar NoFollow/Follow backlink ratios to your competitors.
There is no “golden rule” like a 20:80 ratio for NoFollow Links vs. Follow Links. Every industry, topic, keyword, language and country has different rules.
From the findings above, it seems that reviewing the link risk of NoFollow links is still a must. Against different statements from Google, any link can potentially lead to a Penalty.
In order to respond to the different views regarding NoFollow links, Link Detox (DTOX) grants users the possibility to analyze or ignore NoFollow links while performing link audits. We always recommend analyzing NoFollow links, but we leave it up to you.
With the Superhero Plan you can perform link audits, link cleanup, link disavow boost, competitive research, professional SEO and backlink analysis for your own or your competitor's sites.
