Toxic Link Glossary


The Toxic Link Glossary is inherited by other projects to ensure a common language and avoid confusions in all processes and systems of the company.

This website was set up as a free SEO Resource for everyone to learn about Toxic Links. It contains material previously only accessible to paid users, or members of trainings.

We at LinkResearchTools are obviously biased, and we don’t try to deny that. Having worked in the SEO industry for 20 years now, with LRT being the product of choice for many SEO professionals in high margin niches since 2009.

Nobody is perfect, but we agree, when people call us the authority in toxic links, link analysis and of course recovery from Google penalties.

If you think we can learn from each other, please do let us know.

Challenge us with your knowledge and let us exchange notes.
