I'm building PetSignal — a browser-based AI that reads dog and cat body language from a photo and flags stress signals (whale eye, freezing, lip curl) before they escalate. It's a solo project, the core purchase is a $2.99 credit pack, and that one number dictates the entire growth strategy.

Here's the math that rules everything: at a ~$3-10 one-time AOV, paid ads can never work. US pet-niche CPC runs $0.5-2; even at optimistic conversion rates you're paying $50+ to acquire a $3 customer. So the product lives or dies on organic search. That constraint turned out to be a gift — it forced me to treat SEO as an engineering discipline with real feedback loops instead of a checklist.

Twenty-eight days of Search Console data later: 230 clicks, 15,953 impressions, and impressions in the second half up 105% over the first. Small numbers, real slope. These are the five things the data actually taught me.

1. Symptom pages beat product pages — but not the way I expected

My content engine is ~35 "symptom pages": Dog Opening and Closing Mouth Repeatedly, Cat Whale Eye, Cat Breathing Fast. Each one answers a moment of owner anxiety that ends with a photo the owner has already taken — which is exactly what the product analyzes.
