When evaluating a website’s backlink profile, use a Network Graph to visually identify clusters of potentially manipulative links such as private blog networks (PBNs). Red dots or clusters in the graph indicate suspicious domains that may be part of link schemes. Avoid building links from these sources to prevent penalties from search engines. Instead, focus on networks with a spread-out web of mostly green dots, which represent niche-relevant and reputable backlinks. This approach saves time and improves the quality of your link building by steering clear of toxic networks. [Semrush]
