In the world of SEO, the quality of your backlink profile is paramount. Search engines, particularly Google, are highly attentive to the source of your backlinks. A key concern is being linked from websites that share the same Class C IP address, especially if those websites are low-quality, spammy, or part of a Private Blog Network (PBN). A large number of links from sites on the same Class C network can be a red flag, signaling an unnatural link scheme. This can lead to a Google penalty, significantly harming your search rankings.
