For twenty years, "ranking" meant one thing: get indexed, get crawled, get a position on a results page. Every Shopify store's SEO checklist was built around that single goal. Sitemap submitted, meta tags filled in, Core Web Vitals green, done.
That checklist still matters. It's also no longer sufficient, and most stores haven't noticed yet.
Two different systems, two different jobs
Google's index and an LLM's answer engine are not the same kind of system, even though they both "read" your store.
A search index is a retrieval system. It crawls a page, tokenizes the content, stores it, and matches it against a query at request time. Ranking is a function of relevance signals backlinks, click-through behavior, freshness, page experience. The unit of output is a list of links. The user does the synthesis.
