Most platforms in the SEO/AEO/GEO space sell prompt analytics: run a sample of prompts, watch what a model says back, call it a "visibility score." We're skeptical — prompts are synthetic and model outputs are intentionally non-deterministic, so the same prompt can return different answers on different runs. A metric that isn't reproducible isn't measurement. That's why Kachi sits in a minority position: we start with on-domain optimization — measuring access, comprehension and influence parameters across your website — because it's the one lever you control and can verify.
On-domain work is necessary, but not sufficient. YouTube is the most cited platform — roughly 23.3% of Google AI Overview citations on average (as high as 93% in some verticals), ahead of Wikipedia and google.com itself (Surfer SEO, 2026). Perplexity and AI Overviews alone drive over 75% of AI platforms' YouTube citations (OtterlyAI, 2026). That's not a niche channel — it's core infrastructure for how AI answers questions in your category.
Here's the part most brands miss: AI systems primarily read your video through its transcript, not its footage (Contently, 2026). Auto-generated captions routinely mangle industry-specific terminology, product names, and the names of the partners, customers, and employees your buyers are actually searching for. Every misread term is a missed mention — and a missed chance to build topical authority with the models your prospects are asking.
Done right, this is fixable and compounding. Chapters and timestamps aren't cosmetic — they're the same "key moments" infrastructure Google built for Search years ago (Google, 2021), and 73% of AI Overview video citations today pull from timestamped chapters, often cited repeatedly across 2-5 segments per video (Rankshift, 2026). Notably, none of this correlates with view count or subscribers — a properly structured video from a small channel competes evenly with a large one.
On-domain content earns AI trust. Structured video earns AI reach. Brands serious about the next era of search need both.
