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

Google, Microsoft and OpenAI plan to honor a shared website signal for opting out of AI training, according to Search Engine Journal. The approach could give site owners a way to communicate that preference to several providers through a single line in robots.txt.

The idea is a shared opt-out rather than a separate instruction for each company. That distinction matters for marketers responsible for managing website content: a single signal could offer a more streamlined way to express a training preference across multiple providers. The companies involved, however, are handling the approach differently.

The available summary does not specify the robots.txt line, explain the differences between the companies’ approaches or say when the shared signal will be available. Those details are important for anyone considering a change to a site’s settings. The plan should not be treated as confirmation that every provider will interpret or implement the instruction in the same way.

For marketing teams, the distinction between a site’s stated preference and a provider’s handling of that preference is worth checking. A shared instruction may be intended to communicate the same choice to several companies, but the information available here does not establish the precise effect of that choice for each one.

The reported plan also concerns opting out of AI training specifically. Marketers should avoid assuming that an instruction for that purpose covers other uses of website content. Before making a change, they should check the relevant documentation for the exact directive, its scope and the way each provider says it will respond.

What this means for marketers

If your team is reviewing how website content may be used for AI training, follow the providers’ guidance before updating robots.txt. Confirm the instruction to use and check each company’s approach rather than relying on the expectation that a shared signal will operate identically everywhere. The available summary alone is not enough to implement the opt-out.
