The context
Northstar is a specialty outdoor retailer for ski touring, climbing, and trail — staff averaging eight years in the sports they sell. Online, that expertise lived in chat logs and a few buying guides.
In early 2026, ChatGPT Shopping and Perplexity almost never cited Northstar, even on queries it was perfectly placed to win. Competitors with thinner ranges but cleaner data took the recommendations.

What they kept
The asset they kept is the criteria. The buying logic is now explicit and structured, so it works for AI search, for on-site comparison, and for the next hire — instead of leaving with whoever knew it. A weekly coverage test keeps new products from lowering it.
