1. Functional differences
In a private blog network, the website owner will use a private network of blogs in which he or she will include links pointing to the main site he or she also runs. The owner of PBN can also decide to sell links to other site owners. The intention of interlinking pages in the PBN network via links is to increase Citation Flow or CF which is a ranking measurement based on the number of sites a link is connected to.
In contrast, Web.20 backlinks are generated from publisher type websites such as social media and video sharing platforms these platforms, as it may be known, allow users to create content and post on it for hosting. The publisher’s website is usually owned by company or different person and allows multiple users to publish content that the site will host.
In the case of web 2.0 backlinking, the owner of a site generates content and posts on the social media or bookmarking sites or other publisher networks and includes links pointed back to their main site.
In most cases, while the PBN websites are simpler websites interconnected to each other, the web 2.0 platform is more of a content hosting or streaming platform.
A PBN’s main intention is to generate links on an interconnected blog network rather than providing valuable information. They use unnatural methods of building links, meaning they are not necessarily following SEO promotion guidelines as would be required by search engines.
Most of these PBN networks are closed from the public in one way or another in order to avoid detection by search engines since they use manipulation in link building without following the stipulated guidelines. For instance, poor ranking by search engines would result given that the quality of content on these sites is poor. Most owners also use different hosting providers for each site to hide the digital footprint. For this reason, these links score a low TF or trust flow, a ranking measurement based on how truthful a link is.
In contrast, web 2.0 backlinks are a white-hat SEO technique approved by search engines and the links will pass on as good quality given that most publisher websites such as YouTube already have genuine ranking since they have many users posting original content and genuine links.
That is not to mean users can’t practice blackhat SEO through web 2.0. In some cases, a user can build multiple accounts on a publisher network and post bulk content filled with keywords and links pointed back to their main website for which they hope to achieve high SEO ranking. These links score a low TF.
3. High versus low DA and PA
Niche websites can use this blackhat method to generate links across the internet in order to generate more traffic and to increase ranking in SEO. When considering the value of paid versus free traffic or link building, this is more preferable but will also involve some cost for buying domains with high DA or domain authority and then hosting domains. It is also recommended to purchase domains with a clean link profile and those that are free of spammy and toxic backlinks.
Once the domain is hosted, the owner posts content containing links. These links point to another main money site run by the same owner, and the intention is to pass on the link strength and increase the search ranking of the main site.
In web 2.0, the owner will build a good PA by publishing a page on the publisher who already has a high DA. The user is not responsible for building high DA on the publisher site as is with the case of PBN. They are also not responsible for hosting the publisher’s website or network.
Web 2.0 helps generate more TF compared to PBN.
