Is shipping an llms.txt file worth an afternoon in 2026?

The conversation about "Agentic SEO" is getting messy. Is the new llms.txt standard an architectural necessity or speculative bloat?

I just published a data-driven analysis of how AI agents are consuming the web and how Indie Hackers should actually optimize content.

Key insights:

Token Math: llms.txt can cut token usage up to 10x, but this only helps an agent after it has already decided to visit.

Adoption Paradox: High-traffic sites are actually adoption laggards (8.27%) compared to mid-tier experimenters.

Google’s Pivot: The signal from Google I/O is that functional, interactive protocols like WebMCP matter far more than static text files.

Data shows that clear information architecture—direct answers and clean headings—remains the primary driver of AI citations, not the presence of a single text file.

I’m curious to hear your take. Are you prioritizing llms.txt, or focusing purely on structure?
