What is the number one risk factor for PBN and how to keep your investment (time and money) working for you long term

What is a Private Blog Network

What is a Private Blog Network (PBN)?

The purpose of a website is to find its relevant customer/client base. This is achieved through techniques known as Search Engine Optimization (SEO) – techniques used to optimize your website, both in terms of structure and content, so that Google knows your website is relevant to the traffic that is searching for your content.

One of these SEO techniques involves developing a PBN, or private blog network. At its most fundamental, a Private Blog Network is about developing links. The more relevant links that point to your website the more Google trusts your website as an authority in that area. Before moving on, though, let’s first discuss what we mean by a Private Blog Network.

What is a Private Blog Network?

If you don’t know what a Private Blog Network is, don’t worry. The concept is remarkably simple to understand, whereas its effects can be enormous. Think about it this way – website owners want to drive as much relevant traffic to their website as possible. What they don’t want is traffic that is uninterested in the product or service provided by that website.

To drive traffic to your website, Google needs to have some evidence that your website is an authority on that subject. For example, if you owned a website on education, then links from .edu domains (university-based websites, for example) let Google know that your website is trusted by other, more serious sources.

And this is where a Private Blog Network comes in.

A Private Blog Network is a network of expired domains. These domains link with each other, and link through your website, to add credibility and authority to your main website. The more links you have, the more relevant Google considers your website. It’s important to preface, however, that Google should remain unaware that all these websites are yours.

If Google somehow becomes aware that these websites are all yours, search engines will downgrade your website’s standing. This means that people searching for your website will find it more difficult to access, not least because your website will appear further down the search engine pages. That’s why a PBN is referred to as ‘private’ and not public.

You might be wondering, then, why a PBN network should remain inaccessible to Google?

That’s because Google wants to naturally rank websites. If someone owns eight different websites and seven of those websites have seven links pointing to your main website, this undermines the purpose of Google’s search engine. They want natural, not synthetic, search ranks. Not only is it considered synthetic, but it’s also considered spamming.

So now that we understand what a Private Blog Network is, we must now delve deeper into the quality of the links of that network.

Understanding Metrics

Search Engine Optimization is, at its heart, a simple and comprehensible subject. Even for those who do not have technical or digital backgrounds, the concepts are easily absorbed if you take the time and make the effort. When applied, the results can be very impressive.

So, when faced with seemingly technical terms, such as ‘metrics’, try not to recoil from what might seem a technical subject and instead embrace what is, after all, a very clear and absorbing and – in fact – interesting subject.

When we talk about metrics, we’re talking about the factors that influence the strength of a link. In Google’s eyes, not all links are of equal worth. Some links are more valuable than others and there are clear factors, or metrics, that determine link quality.

In terms of SEO for Private Blog Networks, we’ll explore the purpose of four metrics:

  • Domain Authority (DA) – the strength of a domain
  • Page Authority (PA) – the strength of an individual page
  • Trust Flow (TF) – the strength of websites directed to your main website
  • Citation Flow (CF) – the strength of links directed to your main website

There are various online tools you can use to measure each of these metrics. For example, offer excellent tools to measure Trust Flow and Citation Flow, whereas Domain Authority and Page Authority can be measured using

There are websites – such as – that allow you to purchase an expired domain. Don’t forget that Private Blog Networks are built through the existence of expired domains; expired domains that are an authority in your chosen website field.

The state of your hosting matters, too. IP addresses of the various network sites needs to be different. After all, Google will be able to trace a family of websites if all IP addresses just happen to be pointing in the same direction.

IP addresses must, in other words, have different C-classes.

Where to find expired domains?

There are numerous ways, some costlier than others, where you can find expired domains.

  • The first method is to locate a broker. These brokers are experts in finding the ideal expired domain for your website and Private Blog Network. However, they come with the disadvantage of being quite expensive.
  • The second method is to use backordering. Backordering – a service provided by operators such as Expired Domains and Dynadot – purchase domains from the moment they expire. They know, in advance, which domains are about to expire.

Keep in mind – it’s important not to let Google know about the Private Blog Network. Avoid keeping your Google Mail account open as you move between different sites, for example. Always try to reduce the probability that Google can trace your movements.

Final thoughts

Of course, there is little point taking the time to develop the Private Blog Network if your current site has no authority on the subject. Try to keep your website regularly updated with unique, engaging, and relevant content. Let Google know you’re serious about this.

If you don’t, then Google might become suspicious about a wealth of authority links pointing – in quick succession – in the direction of your website. If done correctly, however, a Private Blog Network can add immense value to the value and authority of your website.
