What Is a Toxic Link (And How It Can Kill Your SEO)
In SEO, not all backlinks are created equal. While high-quality backlinks from reputable domains can boost your rankings, toxic links do the opposite. A toxic link typically comes from a spam site, link farm, or irrelevant source that Google considers manipulative. These links often violate Google's Webmaster Guidelines and can lead to penalties or lower visibility in search engine results.Toxic links usually exhibit one or more red flags: unnatural anchor text, high spam scores, irrelevant niche, paid link schemes, or high outbound link ratios. If your backlink profile includes multiple toxic links, your site may be flagged by Google's algorithm or even hit with a manual action, drastically reducing traffic and domain authority.
