Our Commentary ​

This is fascinating. The idea of "Generative Engine Optimization" is already here, and we're seeing the first real-world data points. The site: operator usage is a clear signal of more controlled, perhaps curated, information retrieval. I'm genuinely curious about the implications for content creators. Will we see a new wave of AI-specific SEO tactics? The Reddit reduction is also telling; it feels like a move towards more authoritative sources, or at least away from the noise.
