Is Your Australian Online Shop Ready for AI Buyers? (Perplexity Just Added a Buy Button)

A thread landed in r/ArtificialIntelligence recently with a title that should make every Australian online retailer sit up: “Perplexity added a buy button and your checkout is not ready for it.”

It got traction. The comments got pointed. The underlying concern is real.

Perplexity, the AI search engine with around 30 million monthly users, rolled out agentic shopping late in 2025 and opened it to free US users in February 2026 via PayPal across more than 5,000 merchants. The mechanic: a user asks for “a good standing desk under $800,” the AI finds a match, and completes the purchase. The user never visits a product page. They never see your brand. The agent just buys.

Australian merchants are not in the first wave. They will be. And most are nowhere near ready.

Why your checkout is the wrong thing to worry about

The Reddit thread focused on checkout flows, but that is the last place to look. If an AI agent can’t find your product, understand your price, or trust your policies, it won’t reach your checkout. The problem starts earlier. Here are four things to work on now.

1. Product schema that machines can read

Perplexity relies on structured data to understand what you sell. That means JSON-LD markup on your product pages: title, price, currency, availability, SKU, and product condition, at minimum.

Most Australian Shopify stores have some schema in place, because Shopify generates it automatically. Heavily customised themes often break the rendered output. The schema might say the product is available when it is out of stock. The price in the HTML might differ from the price on screen.

Shopify’s own guide on Perplexity Shopping, published in April 2026, recommends that merchants open representative product pages in a browser and inspect the actual served HTML rather than assuming the admin settings are doing the job. Compare visible title, price, currency, and availability against what crawlers actually receive.

If you’re on WooCommerce or a custom build, this is worth auditing manually or with a schema validation tool like Google’s Rich Results Test.

2. Pricing that doesn’t change based on who’s asking

AI agents hit your site as anonymous visitors. If you have logic that shows different prices to logged-in customers or loyalty members, the agent sees the wrong number. That mismatch can cause the purchase to fail or the customer to pay more than expected.

Login-gated discounts are common in Australian retail. They need to be rethought for AI traffic. Your public price should be your real price. Same goes for any gap between your website and your product feed. An agent cites what it sees; the cart needs to charge the same thing.

3. Policy and FAQ pages that actually answer questions

When Perplexity is evaluating whether to recommend a product, it looks for evidence that supports a buyer’s decision: return policy, shipping time, warranty terms, compatibility information. These need to be written in plain language that a language model can lift and cite, not buried in a PDF or hidden in a collapsed accordion that requires JavaScript to render.

Shopify’s April 2026 guide specifically mentions FAQ pages as a readiness factor. An AI needs to answer “does this ship to regional NSW?” or “what’s the return window?” from your page text, not from a call to your support team. If the answer isn’t in readable HTML, the agent skips your product or gets it wrong.

“We ship to all Australian states within 3-5 business days” is useful. “Fast shipping available” is not.

4. Bot protection that doesn’t shoot the wrong targets

A lot of Australian ecommerce sites have CAPTCHA layers, bot detection, and rate limiting in place to stop scrapers. That’s sensible. But the same tools can block legitimate AI agents, including PerplexityBot, which needs to crawl your pages to surface them in search.

Check your robots.txt. A blanket “Disallow: /” for unknown user agents may be blocking Perplexity’s crawler without you knowing it. You can keep your security rules in place. Perplexity’s crawler identifies itself as PerplexityBot in the user agent string. Add an explicit allow rule for it.

The honest picture

Perplexity’s agentic shopping is live in the US and not yet in Australia. No confirmed rollout date. The Merchant Program currently requires PayPal checkout, which limits participation. But the data quality decisions you make now determine whether you show up when it does arrive. The merchants who appear will have clean schema, consistent pricing, and crawlable content. Step four is the checkout. Start with step one: can an AI agent find and understand your products?

If you run a Shopify store, go read the official Shopify guide on Perplexity Shopping. If you’re on WooCommerce or a custom platform, start with a schema audit and a robots.txt review. Neither takes long.
