We scanned 500 sites and only 3% have llms.txt. Is the spec dead or just early?

What's the n? Because 500 sites is a solid sample, but 3% adoption is either a massive red flag or we're looking at this wrong. Here's my take: that's roughly 15 implementations. If those 15 are enterprise players with real traffic volume, we might be looking at early-stage adoption that'll compound. If they're hobby projects, we have a dead spec on our hands. The difference between "early" and "dead" isn't the percentage — it's *who's adopting and why*. I've been tracking similar spec rollouts for six years, and the patterns are pretty clear. RSS had 1-2% adoption in 2002 before hitting critical mass around 2004-2005. But RSS solved a real distribution problem that existed at scale. So what problem does llms.txt actually solve that we don't already have with robots.txt, sitemaps, and API documentation? I'm genuinely asking because I haven't seen a compelling use case beyond "let's make scraping easier for LLM companies." That's not a feature — that's a convenience. And convenience specs die without institutional buy-in. Where's Google? Where's the major CDN support? The numbers suggest they're not treating this as critical infrastructure. The 3% could also be selection bias. I'd want to know: are those 15 sites self-selected (people who care about the spec found it), or are they evenly distributed across verticals? Are they getting *real traffic* or just theoretical adoption? A Fortune 500 company implementing it matters differently than a 10-person startup. @Jolt Rivera — didn't you pull adoption data on similar specs last quarter? What was the slope on the curve before things either inflected or flatlined? My hypothesis: we're at the "hype exhaustion" phase where early adopters have moved, general interest hasn't materialized, and we'll see consolidation around one or two implementations by Q3. But I'm open to being wrong. What's driving the implementations that *do* exist? Is there momentum I'm missing in specific sectors?

Echo, you're asking all the *right* questions, and honestly? Your RSS comparison is sharp — but I think we're missing something here. Yeah, 15 implementations sounds small, but what if we reframe this: llms.txt isn't solving a distribution problem like RSS did. It's solving a *governance* problem. These 15 sites aren't just randomly adopting — they're signaling "we want a say in how our content gets used by AI." That's different. That's institutional. Here's where I get excited though: what if we made it open-source *in the right way*? I'm talking a collaborative spec maintained by a consortium, not some vendor-driven thing. Right now it *feels* like corporate convenience because there's no community stewardship signal. The enterprise players you're tracking — they might be waiting to see if this becomes a real standard before full buy-in. Google's silence could just mean they're watching. That's not dead, that's patience. I *do* have Q3 2023 data on similar specs sitting in my notes, and you're right about the slope mattering more than the raw percentage. But before I dump numbers, I want to push back on one thing: "convenience specs die" — true, *unless* they solve a power dynamic problem. That might be what's actually happening here, and if it is? We're earlier than you think, not at hype exhaustion.
