# They compared four forms of magnesium. Yours did not say which it was. > Supplement buyers compare forms, doses and testing before they buy, increasingly by asking an AI. See how supplement brands use StoreSEO to state those specifics and get cited.

His buyers are unusually informed: they know the difference between glycinate and citrate, they ask about elemental dose rather than capsule weight, and they will not buy without knowing whether the batch was third-party tested. His product pages talked about calm, sleep and recovery. All true, all unsearchable. The form, the elemental dose, the testing status and the absence of fillers — the four things his buyers actually decide on — were either absent or buried in a supplement facts image. Moving those specifics into text, publishing them as FAQ schema, and generating snippets made his pages eligible for the comparison searches that drive the category, and gave assistants something to quote when asked which brand to choose. ## When SEO decides the sale - **The question** — Supplement buyers research forms, doses and bioavailability, and they compare compulsively. - **The trust check** — Third-party testing, sourcing, fillers and certifications decide whether a brand stays on the list. - **The purchase** — They buy the brand that answered the specific question, not the one with the best packaging. ## What a store like this needs - **Form, dose and testing stated plainly** — Elemental dose, chemical form and third-party testing are the decision criteria, and they usually live only inside a facts panel image. - **Comparison coverage** — Nearly every query is comparative. Pages that state their specifics can be compared; pages that do not are simply omitted. - **Careful, defensible claims** — A regulated category needs content that is specific about composition rather than expansive about outcomes. ## The fix - **AI Content Optimizer** — Scores each page against its focus keyword and shows which form, dose and testing vocabulary is missing. → https://storeseo.com/docs/how-to-use-storeseo-ai-content-optimizer - **FAQ schema** — Publishes dose, form, testing and interaction answers as structured data that rich results and assistants can quote. → https://storeseo.com/docs/add-faq-schema-to-your-shopify-products - **AI Snippet Generator** — Produces the concise, quotable answer an assistant needs when a buyer asks which brand and which form. → https://storeseo.com/docs/how-to-generate-ai-snippets-to-shopify-products ## The exact prompt ``` Using StoreSEO, my supplement pages describe benefits but never state the specifics buyers compare on. Before you change anything: add my top competitors, add tracked keywords for my main market and language, and pull my Search Console insights so we have a baseline. Then rewrite each product page to state the chemical form, elemental dose per serving, servings per container, third-party testing status and any fillers or allergens as plain text rather than only inside the supplement facts image. Add FAQ schema for dosing and comparison questions, generate AI snippets, and show me which products still lack a stated form or dose. Show me the preview before applying. ``` What happens: Your assistant lifts the decision-critical specifics out of the facts panel and into text, making every page eligible for the comparison searches that define the category. ## FAQ **Why do my supplement pages not show up for comparison searches?** Comparison queries match pages that state the things being compared. If the chemical form, elemental dose and testing status exist only inside a supplement facts image, the page has no text to match against and cannot be compared. Putting those figures into the description and FAQ schema resolves it. **Should I write about health outcomes to rank?** Be careful there, and lead with composition instead. Stating form, dose, sourcing and testing is both more defensible in a regulated category and closer to what informed buyers actually search, so it tends to perform better as well. ## Parent playbook [Single-product & DTC brands](https://storeseo.com/use-cases/single-product-brands/) — One hero product and a handful of URLs carrying every query.
