Vivian's bottom line: AI can only recommend what it can understand. At GNC, that meant treating product data as the foundation of AI discovery, with every ingredient tagged and every attribute clean. It also meant pairing that technical work with the long game of PR, community, and reviews, and starting small with a tool the team could shape, until skeptics became the ones pitching new ideas.

FAQ

Vivian Chang is a consumer marketer and operator who most recently worked at GNC and now does independent consulting while building a community that supports operators. She started in agency-side performance marketing and digital marketing, launched an app for the ecommerce affiliate player RetailMeNot, went direct-to-consumer in meal kits with Plated, and then worked in CPG at Clorox, building direct-to-consumer and digital brand experiences for brands like Burt's Bees, Brita, and several supplement brands. That path gave her experience across affiliate, D2C, CPG, and retail.
Big, and it's where Vivian saw the earliest opportunity. She cites a recent stat suggesting that around 30% of queries into assistants like ChatGPT and Claude relate to health and wellness, such as whether someone should take a supplement or whether they need creatine. From what she's seen, AI discovery is strongest in health, beauty, and personal care. Fashion is starting to show up, but she believes shoppers will always want to keep the fun part of shopping for style for themselves.
The first step was understanding where GNC ranked and how visible it was. SEO had existed as blog content and on-site tagging but hadn't received the attention it needed, so it became a much bigger priority. The team added FAQs to product pages, built content hubs around trending topics like creatine and protein, and worked with two outside vendors. One built long-tail product pages, such as energy supplements for college students, pairing a short blurb with a curated set of products, and those pages quickly started appearing in Google AI Overviews. The other effort, publishing a higher volume of AI-written, human-reviewed content starting at the end of 2025, hasn't shown as much success yet.
Because AI can only recommend what it can understand. Vivian says one of the most useful realizations at GNC was that product data fundamentally needed to be cleaned up for AI discovery. The team partnered with someone she now describes as a forward-deployed engineer, who built a tool that cleaned up product attributes and made sure every ingredient was separately tagged, clean, and searchable. The same tool could surface trends quickly and match them to the products that fit. Before, someone on the science and research team had to manually break each ingredients panel into distinct rows and labels.
Mostly to research, at least for now. Even in health and wellness, Vivian saw a lot of topical searches, like a woman asking whether she really needs creatine, whether it causes bloating, and what to take it with, and far fewer requests to name the three brands to buy. That places AI search in the research and consideration phase of the funnel rather than at the purchase decision, though she expects some shoppers will increasingly let AI decide for them. Kailin adds that across Noibu's customer base, LLM traffic is growing and converts well but is still a small share of overall traffic.
Less than people expected. Vivian says everyone treated AI and AEO as their own distinct island, but in practice it comes down to the normal things, like PR, community, and SEO, done in a more integrated and prioritized way. Answering questions isn't enough if your brand isn't part of the conversation, and AI also reflects the positive or negative sentiment around a brand. That means technical fixes and content need to be paired with community, reviews, and PR, which are longer-term efforts that take time to show impact.
Sometimes you have to mandate it at first. When GNC rolled out its product data enrichment tool, the ecommerce item-setup team was skeptical because they believed their process was already fine. Vivian required them to put 20 new products a week through the tool and report back on what was working and what was breaking. Eventually the team got it, got excited, and started proposing new ideas once they realized AI let them custom-build tools for their own workflow rather than being handed another SaaS tool they had no say over. The tool also had an unexpected payoff for merchants: updating registries and certification records across roughly a thousand products used to take about 20 hours, and now takes about an hour. Her advice is to start small, get early wins, get people hands-on, and consider partnering with a contractor or vendor until the team builds AI fluency.
Most companies, GNC included by Vivian's own account, are still AI-enhanced, using AI to speed up human processes rather than rebuilding those processes around AI. She says the biggest barriers are being unclear about the outcome you want and not giving AI enough context to understand what good and bad look like. Many organizations lack clear documentation and requirements, and their outputs change frequently, which makes AI-native workflows hard to build. Feeling hopelessly behind leads to paralysis, so she recommends picking somewhere to start and iterating. On vendors, she sees a gradient: she wouldn't swap out core personalization tools that are building AI quickly, but some tools are worth replacing. GNC piloted an AI that looks across heat maps, session replays, and event funnels together and returns opportunities, instead of using three separate tools and synthesizing the results by hand.
Vivian expects the next wave to be AI-connected marketing communications to consumers. Many teams already use AI for paid media optimization or creative, but few have connected what a shopper does on the site with how they engage with email and paid media. Linking those would bring the industry closer to the one-to-one personalization marketers have always wanted, though she says it's only at the very beginning. She believes it will require as much human retraining as new tools, since roles like an email marketer who sends a weekly campaign will shift toward personalized content and advanced segmentation. She also hopes the market consolidates so teams no longer have to learn a new AI tool every week.
