This comprehensive guide will teach you what parasite SEO is, how to implement it safely and effectively, plus best practices to build high authority backlinks from reputable sites.

A New Form of SEO for Ranking Success

Parasite SEO offers a shortcut – leveraging the existing authority and domain metrics of reputable external sites to give your own site a boost.

How Parasite SEO Works

Unlike black hat techniques, properly executed parasite SEO is a legitimate, white hat SEO tactic.

Parasite SEO involves creating and publishing optimized content on authority sites that allow contributed submissions. Your content contains natural links back to your own site.

  • Review your niche’s authoritative publications and blogs.
  • Check forums and review sites related to your products/services.

  • Avoid sites selling links or posting paid contributions only.

Choose Target Keywords

  • Use keyword research to find relevant topics aligned with search intent.

  • Consider secondary long-tail keywords too.

Create an Outreach List
