Which prospects metric in the Link Building tool represents the extent to which a certain domain with a link to your website could be harmful to your website and affect your ranking in search engines?

Toxic rank is the correct answer because it directly measures the potential harm a backlink from a specific domain could inflict on your website's search engine ranking. A high toxic rank indicates a higher likelihood of negative impact, often due to spammy practices or low-quality content on the linking domain. Trust score, while related to domain quality, is a broader metric that doesn't specifically quantify the harmful potential of a link. Internal linkRank, on the other hand, is completely irrelevant as it pertains to the distribution of authority within a website's own internal links, not the quality or risk of external backlinks.
