Google is the most used search engine in the world. Search engine optimization and SEO are essential for efficient information search on the Internet. However, the Google search algorithm is a problem with black hat SEO. What is PBN (A private blog network), one of these black hat SEOs?
The Google search engine was started in 1996 as part of a research project by Larry Page and Sergey Brin, both PhD students at Stanford University. Until then, search engines had a structure that evaluated the frequency of words or phrases matching the search term appearing on the website in the search results. However, Google has adopted PageRank, which analyzes the relationships between websites and evaluates their ratings. PageRank allows the popularity or importance of a website to be reflected in the search results, so that Google displays websites with a certain quality or higher that are attracting attention at the top of the search rankings. As of June 2019, the Google search engine, which has been around for more than 20 years, occupies a market share of 92.62%.
At first glance, PBN seems like a decent blog. The number of site collections asking for a link to the page you want to promote. Unlike simply linking a large number of links side by side, PBN has article content specialized for a specific topic. PBNs tend to rank higher in search rankings by increasing links on other websites. It is an attempt to forcibly increase the search ranking by taking the PageRank characteristic as the inverse and attaching links from various sites.
Black Hat SEO companies say that thousands of PBN sites are in operation, and they make a profit by setting a price of millions of won per link. As the number of these sites grows, the Google search engine may not be able to fulfill its original role of being able to find the desired information.
While Google and Facebook are growing as excellent advertising media, there are many media that are disappearing. If the media goes out of business, the domain you registered for will also expire and you will be able to buy it again. Some deleted domains have great value in the links themselves. A bad guy can immediately buy these domains and replace the content with links to the sites they want to promote.
Not only links, but also the fidelity of the content on the site are important factors in order to rank high in search rankings. Blog text can be written by anyone at an affordable price. It is also possible to convert documents with tools using AI. In addition, some PBN sites are said to be conducting research to add readability and personality by manually adjusting automatically generated documents.
Google has been making moves to crack down on PBNs since 2011. In 2014, there were reports that Google sent warning emails to sites suspected of being PBNs and removed them from the search index. However, the PBN side is also working out various technologies to escape from Google’s monitoring, so a situation is occurring. Theoretically, it is quite difficult to find a PBN completely and therefore to subtract it from the overall search results.
What Google can do is elevate the way sites are detected. Given that AI-powered content creation tools, the know-how to create new sites in minutes, and black-hat SEO companies have been avoiding Google for years, it is likely that it will be difficult for Google to eliminate them all in the future. high.
