In our previous analysis, Effect of Nofollow on LLM Training, we established a grim reality for the privacy-conscious webmaster: AI training bots do not respect the rel="nofollow" attribute.

For two decades, nofollow was the gentlemen’s agreement of the web. It was a digital “Do Not Enter” sign that search engines like Google and Bing respected to manage authority flow (PageRank) and combat spam. It was a protocol built for an era of retrieval, where the primary value of a link was the endorsement it carried. If you didn’t want to endorse a site, you added the tag, and the “juice” stopped flowing.
