Do Nofollow Backlinks Help SEO? Yes! Here’s Why.
Backlinks are a big deal in the world of SEO. Most backlinks pass authority, causing Google to evaluate your site as being more trustworthy. And of course, more trustworthy sites are more likely to rank higher in search results. But what about nofollow links? What are nofollow links, exactly, and are they important for your SEO strategy? Nofollow Links: The Basics By default, Google bots crawl the web on a constant basis, following links and using them to determine how PageRank is passed. This is also an opportunity to evaluate “bad” backlinks and penalize the sites they point to. As you might suspect, a nofollow link prevents Google from following the link as usual. Nofollow links are established with a rel=”nofollow” HTML tag, which instructs Google to ignore the link. In the backend code of your site, this is the only distinguishing feature of a nofollow link. When live, a nofollow link is indistinguishable from a standard dofollow link. It looks the same, it can be clicked the same way, and there’s no immediate clue to a user that the link is nofollow. Why is this important? For starters, most search optimizers are heavily focused on improving their authority with PageRank. They employ link building strategies to establish more links to earn more authority and eventually rank higher. Because nofollow links don’t pass PageRank, they can’t help your rankings directly. Note the importance of the word “directly” here. Google has verified this directly: “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.” Why Do Nofollow Links Exist? You may be wondering why nofollow links exist, and why they’re used by various websites, if they’re not so different from standard links. Originally, nofollow links were conceived as an idea to fight back against link spam. In the early days of SEO, practitioners would take any opportunity they could to build a dofollow link back to their website. They would spam blog comments, issue meaningless press releases, and post actively on forums to get more links to their site. The nofollow tag allowed blog owners and other webmasters to fight back against this tendency by making certain types of links nofollow by default. They could also issue the nofollow tag to reduce the impact of a dofollow link they deemed questionable in the body of a guest post. This is useful for nearly everyone involved. The blog gets to preserve its reputation by ensuring it isn’t used for spammy backlinks. Google gets to fight link spam and calculate better search engine results. Web users encounter less spam. And webmasters are incentivized to find better linking tactics. Nofollow links are also recommended for use with paid links. Generally speaking, Google frowns upon paid links. But this is mostly because paid links are considered to be a form of ranking manipulation. If you use a nofollow link, there can be no direct ranking manipulation, since nofollow links don’t pass authority. Problem solved! You can even find a reference to this in Google’s Webmaster Guidelines. It states, “Make a reasonable effort to ensure that advertisement links on your pages do not affect search engine rankings.” It then recommends using a nofollow tag for this purpose. How to Tell If a Link Is Nofollow You can apply nofollow tags to links on your own site, but how can you tell if a link on an external site is nofollow? Sometimes, publishers and external sites will inform you directly about their nofollow policies. But it’s much more reliable to simply check your backlinks yourself. Right click anywhere on the page you’re inspecting and click “View Page Source” or simply click CTRL + U. The code might look somewhat incomprehensible to you if you’re not used to it. But don’t worry. Use CTRL + F to find the link you’re looking for, and see if it has a rel=”nofollow” tag. The Non-SEO Value of a Nofollow Link When people hear that a nofollow link doesn’t pass PageRank, they immediately get turned off. After all, isn’t the whole point of link building to earn PageRank and rank up? Yes, for the most part. But it’s important to understand that nofollow links have a lot of value that has nothing to do with SEO. For example: Referral traffic. This is the big one, so it deserves to be mentioned first. Nofollow links have the power to generate referral traffic to your site. When someone clicks on a link in a blog post they’re reading, they don’t care whether Google is using it to pass PageRank or not. All they care about is reading the content on the other side. Depending on the publisher, the context of the link, and other variables, you may be able to generate thousands of new visitors this way. Brand visibility. Simply including dofollow links, with a named reference to your brand, is enough to increase your brand visibility and raise brand awareness. This is especially powerful as you build your reputation as an author and reach bigger audiences through bigger publishers. Increased attention for your content. Referral links also serve to promote your content. In some cases, just mentioning your content (such as calling out statistics in original research you conducted) can serve your brand well. Otherwise, the traffic you generate for the content will make it more popular. In some cases, a single nofollow link can help make a piece of powerful content go viral. The Value of Nofollow Links for SEO No PageRank, no SEO benefit, right? Wrong. In fact, in addition to all their non-SEO related benefits, nofollow links can have significant value for your SEO strategy. Importantly, Google says this about nofollow links: “In general, we don’t follow them.” If this is the case, it implies that Google occasionally does follow nofollow links. That may sound like a conspiracy theory, but there’s some real evidence to support this. For
