Should You Be Using a Private Blog Network (PBN) for Link Building in 2025?
Private blog networks (PBNs) have been used for years as an SEO strategy. Perhaps you have dabbled in creating one yourself or collaborated (in some cases unawares) with others who own them. Here we’ll discover more about PBNs, including: Definition of a private blog network (PBN) How PBNs are created Pros and Cons of a private blog network History and risks of PBNs Let’s get at it! What Is a Private Blog Network (PBN)? Let’s start with a description of PBNs, including how they work—or at least how they’re supposed to work. A private blog network is a collection (network) of individual, distinct websites (blog) owned by a single person or organization (private), typically for the purpose of generating links for a primary domain. To understand why this could be valuable, you have to understand the basics of link building. When conducting a Google search, Google’s algorithm considers both the relevance of potential websites (whether or not the results are related to your query) and their authority. Their “authority” is a measure of their trustworthiness, which is calculated based on a number of factors; most prominently, this is determined by the number and quality of links pointing to the domain. If you earn enough high-quality links, your “domain authority” will grow, and it will be easier for you to rank in the future. So let’s say you have a primary website and you’re looking to do SEO for your personal injury law firm. If you wanted to build PBN links, you could purchase domains relevant to the law, develop content for those sites, and use them to build links back to your main money site (a glorified and solely-owned link wheel for SEO purposes). This allows you to forgo conventional link building strategies, which require patience, attention to quality, relationship building, and did I mention patience? Hypothetically, all the nodes in your PBN could be used as separate avenues for revenue generation, and tightly interlink with each other. However, this is a problematic approach for a few reasons. First, this would be extremely time- and money-intensive, and your peripheral sites probably won’t be as profitable as your main site; accordingly, this bears out a low return on investment (ROI). Second, the closer your nodes’ relationships are, the more likely they’re going to be targeted with a Google penalty. There are a number of strategies that people have used to improve the effectiveness of their PBNs. For example, it’s common for people to purchase expired or expiring domains for their PBN nodes; these tend to have a lot of existing authority, meaning the links you build with them will instantly be more powerful—without having to wait months for the new websites to mature. Are Private Blog Networks (PBNs) White Hat or Black Hat? In SEO, everything is about quality. You want to provide high-quality, natural content to your readers, and build high-quality natural links on external publishing websites. Accordingly, your SEO “Spidey sense” might tingle when reading a description of how a private blog network (PBN) works. Is a private blog network a black hat or white hat tactic? If you’re building a PBN for the pure purpose of manipulating your search rankings, and your nodes are throwaway sites with no real purpose, you’ll be violating Google’s terms of service. In fact, it’s even possible to report websites and networks engaging in this behavior. In the past, Google has taken manual action against PBNs to limit their influence and dissuade webmasters from building them (which we’ll touch on in the next section). Accordingly, you can describe PBNs as a black hat tactic. That said, there’s a lot of room for customization and improvement in your PBNs. You could build a small PBN of just one or two extra sites, and spend a lot of time fleshing out those sites with high-quality content, genuinely intended to be valuable to readers. In this scenario, your websites would function as independently valuable, self-sustaining entities, with the links you build merely as an added bonus. Here, your PBN could mostly be considered white hat. Because of this, a private blog network exists in a kind of “gray hat” territory. Google explicitly encourages webmasters not to engage in PBNs, but there are ways to make them more valuable. The PBN Google Crackdown of 2014 Of note, Google issued a massive crackdown on PBNs back in 2014, and continues to remain vigilant in handing out manual penalties for suspected offenders. The specific violation cited by these manual actions was typically “thin content.” Some SEO professionals reported traffic drops of up to 90 percent over the course of a single weekend, and were never able to recover using the same tactics as before. If you decide to use PBNs, you need to be prepared for this possibility. There are several ways to guard yourself from penalty, of course. For the most part, Google brings the penalty down on sites that clearly seem related to each other. It often detects this by noting the link relationships between domains, or by noting the public owners of each domain; domains that tightly interlink with each other and are owned by the same person are frequently the target of penalty. You can fight back in a few important ways Make your registration public, or use different registering entities. Don’t allow your websites to fall under the same registration umbrella. Use a diversity of links. If your nodes are constantly pointing to each other, and only each other, it’s going to be a red flag. Make each site independent. While you may be building nodes to “feed” a central important site, try not to make that relationship obvious with your content or structure. Each site should stand independently. Assess publishers. If you’re using a white label link building service or a white label SEO team, you will want to apply strict guest blogging filter parameters to the sites from which you are looking to acquire backlinks.
