I have been testing a few things, and I do not think the basics have changed that much. Good product pages, clear titles and descriptions, schema, and real customer reviews still matter. One thing I’ve started doing is adding FAQs and making product information more complete, since it gives search engines and AI tools more context.
I think it is too early to call it “LLM SEO,” but making your store easy to understand and building trust across different websites is probably the best approach for now.
Good question - this is basically a different discipline from Google SEO. A few things that actually move the needle for LLM visibility:
1. Structured data (Product schema/JSON-LD) - a lot of default themes don’t output it, and it’s the main thing these engines parse instead of your marketing copy.
2. Descriptions that answer real buyer questions (“is this waterproof”, “what size runs true”) - LLMs pull from text that reads like an answer, not ad copy.
3. llms.txt - a few engines are starting to check for this file first, similar to robots.txt.
4. FAQ schema on product/collection pages if you have common Q&A content.
