Google, Microsoft and OpenAI Plan Shared AI Training Opt-Out

Google, Microsoft and OpenAI plan to honor a shared mechanism that would let websites opt out of AI training, according to Search Engine Journal. The proposed approach centers on a line in robots.txt that could communicate a site's preference to several providers at once.

The idea is to give site owners a common way to express that they do not want their content used for AI training, rather than relying solely on separate signals for individual companies. However, the companies involved are handling the shared opt-out differently, so participation does not necessarily mean their approaches are identical.

The available summary does not specify the proposed robots.txt line or explain each company's implementation. It also does not establish when the shared approach will be available or which additional providers, if any, will honor it. Those details matter for publishers deciding how to put an opt-out into practice.

The proposal concerns the use of content for AI training. The information provided does not establish how the shared signal would affect other uses of website content, so site owners should avoid treating it as a blanket statement about every interaction between their sites and AI or search services.

What this means for marketers

Marketers responsible for website content should watch for provider-specific guidance before changing their robots.txt files. A shared signal could simplify the process of expressing a training preference across multiple providers, but teams will still need to understand how each participating company handles it.
