What these numbers mean if you run a business in San Diego

Two stories live in this data. First: some of your neighbors are accidentally invisible to AI assistants - their own settings files turn ChatGPT away at the door, almost always a plugin default nobody read.

Second, the quiet race: 3 of your San Diego neighbors (19% of this sample) already guide AI systems with an llms.txt file - a convention that barely existed two years ago. The businesses that become machine-readable first are the ones AI assistants can quote first. That window is still open in San Diego, but it is closing at street level, not boardroom level.
