In the traditional world of SEO, the rel="nofollow" attribute was a simple, binary instruction. It told Googlebot: “Don’t follow this link, and certainly don’t pass any PageRank through it.” It was the specific tool we used to sculpt authority, manage crawl budgets, and disavow paid relationships.

But the Agentic Web does not run on PageRank alone. It runs on Tokens.

As we transition from optimization for retrieval (search engines) to optimization for inference (LLMs), the rules of the nofollow attribute are being rewritten. The comfortable assumption that a nofollow link protects you from the “bad neighborhood” or prevents a competitor from benefiting from your content is dangerously outdated.
