I've spent the last year looking at why certain Shopify stores show up when people ask ChatGPT for product recommendations and why most don't.

The answer almost never has anything to do with the product itself.

When someone asks ChatGPT to recommend something, it doesn't pull from thin air. It goes out and looks. It crawls websites, reads content, tries to determine which stores are actually trustworthy. Most stores fail that evaluation before the AI gets anywhere near the product page.

There's a file called an llms.txt. It works similarly to a sitemap except it's not built for Google. It's designed specifically for AI crawlers. It gives the model a clear picture of your store's structure, your key pages, your content, your policies, all in one place. It's basically a handshake between your store and the AI.

The vast majority of Shopify stores don't have one.

When I was building a tool to help stores rank on AI, one of the first things I noticed was how consistent the pattern was. Stores that had even basic AI infrastructure in place were pulling way more traffic from ChatGPT, Perplexity, and Gemini than the ones that didn't. Same niche, similar products, similar price points. The difference was whether the AI could actually read the store properly.

The average Shopify store sits around 0.5% of total traffic coming from AI sources. The ones that were properly set up were closer to 10%. That gap is only going to grow as more people skip Google entirely and just ask an AI what to buy.

Most store owners are still building for 2019 while their customers have already moved on to a different way of shopping. Its moving fast, and in my opinion, it’ll only get worse for the people that don't adapt.  

Was wondering what you guys were doing to appear more

Most Shopify store owners treat Reddit the same way they treat Twitter. Something they probably should be on but never really got around to.

That's a mistake that's getting more expensive by the day.

Around 40% of the opinions and answers that ChatGPT pulls from come from Reddit alone. That number came from someone deep in the AI space and it stopped me cold when I first heard it. Because what it means is that Reddit isn't just a social platform anymore. It's one of the primary sources an AI uses to decide what to recommend to millions of people every day.

So when someone asks ChatGPT "what's the best supplement brand for men over 40" or "where should I buy a paddle board online," ChatGPT isn't just guessing. It's pulling from conversations that already happened. Reviews people left. Threads where someone asked the same question six months ago. Posts where a real person gave a real recommendation.

If your brand isn't part of those conversations, you don't exist in that answer.

The stores that are showing up in AI recommendations right now aren't necessarily the biggest ones. They're the ones that built a presence in the right communities early enough that the AI already knows who they are.

That window is still open. But it's not going to stay open forever.

After spending the last few years deep in AI SEO and watching how these recommendation engines actually decide who to surface, one thing surprised me more than anything else.

The stores showing up consistently in ChatGPT recommendations weren't always the ones with the best SEO or the most backlinks. A lot of them just had a serious Trustpilot presence that their competitors had completely ignored.

Something you set up once, forget about, and hope a few customers leave something nice on. That was a reasonable approach two years ago. It isn't anymore.

Trustpilot is now the fifth most cited domain globally on ChatGPT. When someone asks ChatGPT to recommend a product or a store, the AI is actively pulling from Trustpilot reviews as a primary source to determine whether your brand is trustworthy enough to recommend. Citations from AI search tools to Trustpilot grew roughly fifteen times year over year in 2025. That is not a minor shift.

Here is why this matters more than backlinks right now. Google rewards authority. Backlinks, domain age, page rank. That system took years to game and even longer to build legitimately. ChatGPT evaluates something different. It looks for consensus across independent third party sources. A backlink from another website tells Google you are credible. A verified Trustpilot review tells ChatGPT a real person had a real experience with your store and trusted it enough to leave a record of it.

Those are completely different signals and AI weighs the second one heavily.

With 58% of consumers now using AI platforms for product recommendations, the stores that have built a strong presence on third party review platforms are quietly pulling ahead. The AI needs external validation that your store is legitimate. Your own website cannot provide that. Your product descriptions cannot provide that. Trustpilot can.

The stores showing up in AI recommendations consistently have three things in common. Recent reviews, a high volume of them, and responses from the brand that show someone is actually paying attention.

Most store owners are still building backlinks while their customers have already moved on to asking AI what to buy.
