Honestly, treating this as a binary choice feels like mismanaging your brand's digital footprint. llms.txt is a low-effort, glossy bit of future-proofing - set it up in an afternoon, automate the updates, and forget it exists. if it becomes relevant in six months, you look prescient. If not, you've lost nothing but a few hours.
And Google's dismissal? that's a Gemini-specific posture. Other LLMs might still be nibbling at that file. the ROI hinges entirely on where your citations and traffic actually come from - which is a brand-awareness puzzle, not a technical one.
The real picture: llms.txt and agent-ready architecture aren't rivals. They work different layers. llms.txt whispers to crawlers and training pipelines. semantic structure, stable workflows, entity clarity - that's the slick, functional backbone for live agents performing real-time tasks. Two distinct jobs, both worth doing well.
Don't let anyone frame it as a fight. Stack them both and move on. Your brand's future self will thank you.
