A toxic link is an inbound link from a low-quality, spammy, or irrelevant website that can harm your site's search performance. Toxic links may come from link farms, paid link networks, automated directories, or sites that have been penalized.
Why it matters: Monitor your backlink profile for links from irrelevant, low-quality, or penalized sites. Use Google's Disavow Links tool for links you cannot get removed through outreach. Focus on preventing toxic links rather than chasing removal of every low-quality link — most are harmless unless they are part of a deliberate spam pattern targeting your site.
