Perplexity shows its sources. Under most answers it lists the pages it pulled from, and a shopper can click straight through to them. If one of those pages is yours, that is a visitor who already has a reason to buy.
A page gets cited when it answers a question in plain words. "Which candle scent works in a small bedroom?" "What size do I get if I'm between sizes?" A product page with only a photo and a price gives Perplexity nothing to quote.
Pick one question your customers ask before they buy. Answer it near the top of the matching product or collection page in two or three sentences, with details like size, material, or burn time. Check that PerplexityBot is allowed in your robots.txt so it can read the page.
