A pattern from the last 18 months: SA ecommerce brands begin to notice that customer support tickets, sales calls, and demo requests start opening with 'I saw you on ChatGPT' or 'Claude recommended you'. When they check GA4, referral traffic from ChatGPT and Perplexity is showing up in double-digit percentages. But there is no line item for it in the marketing report. It is happening organically to some brands (the ones with strong content and clean feeds) and not to others (the ones running an SEO-only playbook). GEO is the discipline of intentionally becoming one of the brands that gets cited.
The mistake most SA agencies make with GEO right now is treating it as a content-volume problem. LLMs do not reward volume; they reward citation-worthiness. A single well-structured definitive piece on 'best hiking boots for the Drakensberg' will get cited across every major LLM more consistently than 50 shallow product-adjacent posts. The other mistake is treating LLM referral traffic as noise because the sessions per month look small. They are small in absolute count but high in conversion rate: users who arrive from an LLM citation have already been triaged as 'this is a candidate brand', so the session behaves more like a bottom-of-funnel referral than a top-of-funnel search click.
The other channel most SA brands are missing is agentic commerce. Shopify's agentic checkout allows a customer to buy directly through an AI agent conversation, without landing on your storefront. OpenAI's shopping product does similar. The brands that get selected by those agents are the ones whose product feeds have clean categorical attributes, structured descriptions, and surfaceable review data. This is not future work. Shopify Sidekick and OpenAI shopping recommendations already influence a rising share of ecommerce discovery. The brands with the cleaner feeds are absorbing that demand quietly.
