Poison anchor text is a sophisticated link manipulation technique that Google actively penalizes. Understanding what constitutes poison anchor text and how to avoid it is essential for maintaining a healthy backlink profile and protecting your website from algorithmic penalties.
What is Poison Anchor Text?
Poison anchor text refers to using irrelevant, manipulative, or spammy anchor text in backlinks to artificially boost rankings for keywords unrelated to the linking website’s content. This is a black hat SEO technique that violates Google’s Webmaster Guidelines and carries significant ranking risks.
Common Examples of Poison Anchor Text:

- Irrelevant Anchors
- Links using anchors completely unrelated to the target page
- Anchors that don’t match the page’s actual content or topic
- Generic links from unrelated industries
