611: The Shopify Features That Are Exploding Sales For Big Brands With Kurt Elster

Podcast: Download (Duration: 49:22 — 56.8MB)

The Shopify AI features actually moving the needle for big brands right now are AI live chat sales agents, AI-assisted theme block generation inside the editor, AI-populated product recommendations, and Shopify Flow plus the Shopify Knowledge Base app that feeds ChatGPT and Perplexity your product catalog through Shopify’s built-in MCP integration. On this episode of the My Wife Quit Her Job podcast, I sat down with Kurt Elster, founder of EtherCycle and host of The Unofficial Shopify Podcast, to break down exactly which features his agency clients are turning on and which ones are still hype.

Kurt has consulted on hundreds of Shopify stores for over a decade, and I have been running my own ecommerce store for 18 years now. This year is easily the most tumultuous stretch either of us has seen outside of COVID, with AI and tariffs upending playbooks that used to just work.

Below is a breakdown of the Shopify AI features his clients are using to grow sales, the AOV apps worth installing on a bare-bones store, what’s overhyped, and how SEO is being reshaped by AI answer engines.

Key takeaways

• AI live chat sales agents in Shopify are lifting AOV for merchants who deploy them, but you must review conversations because the AI often marks tickets “resolved” when it isn’t.
• Shopify’s in-editor AI block generator (built into the theme editor at no extra cost) writes usable widget code from a one-sentence prompt.
• Shopify Knowledge Base is a free app that exposes your catalog to ChatGPT and Perplexity via Model Context Protocol, and shows you how many times AI recommended your products.
• Traditional and technical SEO (schema, structured data, collection pages sliced by long-tail queries) is the highest-leverage way to get cited by AI search.
• The AOV stack Kurt actually recommends: cross-sells, drawer cart with free-shipping progress bar, free gift with purchase, post-purchase upsells (especially “buy another of what you just bought at 15% off”).
• Most AI apps in the Shopify app store are ChatGPT wrappers charging 10x the underlying credit cost. Vibe-code the simple stuff yourself; buy apps that actually solve pain.

What Shopify AI features are boosting sales for big brands?

The Shopify AI features actually boosting sales for big brands fall into four buckets: AI live chat sales agents, AI-generated theme blocks, AI-populated product recommendations, and Shopify’s new AI-facing catalog surfaces (Knowledge Base and MCP). Kurt confirmed his agency is deploying all four on client stores this year.

Shopify has invested heavily in AI because its CEO Tobias Lutke is a developer-first operator, so the initial wave is framework and tooling that other developers now build on top of. That is why the interesting stuff is showing up inside the admin, inside the theme editor, and as first-party apps rather than as one big consumer feature.

How Shopify Sidekick answers analytics questions in the admin

Shopify Sidekick is Shopify’s built-in AI assistant that answers questions inside the admin, including complex analytics questions about sizes, colors, and inventory forecasting. Kurt tested it on an apparel store with hundreds of listings and asked it to break down which sizes and colors sell for inventory planning, and it nailed the analysis on the first try.

He did not trust the answer, so he ran the same analysis by hand and Sidekick had gotten it right. A year ago Kurt was giving Sidekick a hard time with intentionally tricky questions, and now he is quietly using it for real work.

How Shopify’s AI theme editor generates blocks from a prompt

Shopify’s AI theme editor lets you add a block to any section, describe what you want in one sentence, and have the AI generate the code for that block inside the visual editor at no extra cost. Kurt says this is the single most useful AI feature Shopify has shipped for merchants who are not developers.

The full-theme “generate a theme from a description” tool is less useful. Kurt has tried it several times and says the results feel random, closer to a starting point than a finished theme. The block-level generation inside the theme editor is different because it operates on a small, well-scoped piece of code that Shopify’s engine understands deeply.

Shopify’s Liquid code is well-documented and exposed in a specific way that AI models can parse, so the AI does a remarkable job on small widgets. The tradeoff is that generated code tends to be longer than a human would write, and complex additions can create maintenance headaches later. Simple widgets, sale badges, and layout tweaks are the sweet spot.

How AI live chat sales agents raise AOV on Shopify stores

AI live chat sales agents on Shopify raise AOV by proactively engaging shoppers with product-specific questions the store’s data can answer, and merchants running them report meaningfully higher average order value from shoppers who engage. Kurt runs one on a client store where the app does its own conversion tracking, and shoppers who interact with the agent buy more per order.

The good ones work like a floor salesperson in a retail store. The bot pops up on a product page and asks a question it already knows the answer to (“would you like to know more about the ingredients?”), because ingredients is a meta field it can read. That is a clever prompt design because it engages the shopper with information the AI is confident about.

Two things to watch. First, many of these agents do not identify themselves as AI unless you ask directly. Kurt’s client-facing bot is titled “Virtual Sales Consultant” and when he asked it “are you AI?” it dodged with “I’m here to help with any questions.”

Second, “resolved” is self-scored by the AI, and the AI is generous with itself. Kurt saw one case where a shopper asked “can I return just the lid of the jar?” The bot said “sure, reach out to a sales consultant” and marked the ticket resolved. The store cannot actually take back just the lid.

If you deploy one, audit the conversation logs weekly. Watch for cases where the AI marks tickets resolved that a human would have flagged, and cases where the bot commits the store to something it should not.

How to use AI to populate related-product recommendations

The way to populate related-product recommendations across a large catalog is to run every product image through an AI embeddings model (Kurt and I both use OpenAI’s CLIP-style image embeddings), store the resulting vectors in a database, and then look up similar products at request time. I did this on my own store and it lifted AOV by roughly 17%.

The problem it solves is that on most stores the top 20% of products yield 80% of sales, which means the frequently-bought-together fields for the long tail of products are empty or thin. AI image embeddings let every product on the site have a populated “recommended products” grid that is visually and categorically related, even if it has never sold with anything else.

The hierarchy I use is frequently-bought-together first (using an FP-Growth association algorithm on real order data), and then similarity search from the image-embedding database as the fallback. On a typical Shopify store this maps to the related-products meta field that Shopify’s Search and Discovery app reads.

How Shopify Knowledge Base and MCP get your products cited by AI search

Shopify Knowledge Base is a free first-party Shopify app that exposes your catalog to ChatGPT and Perplexity through Model Context Protocol (MCP), and reports how many times AI answer engines recommended your products. It also lets you write FAQ answers that the AI will use when shoppers ask questions about your store.

Every Shopify merchant is opted into the catalog integration by default. Perplexity and ChatGPT can query your product data structurally, so when a shopper asks Perplexity “what is a good high-protein snack under 200 calories” and your product qualifies, the AI can surface it and the shopper can complete the checkout on your site.

Shopify announced a native ChatGPT checkout integration at its June developer conference, with a preview shipped shortly after. Checkout still occurs on your website today, but a one-click ChatGPT checkout is coming and would use existing Shop Pay payment credentials to eliminate friction.

Kurt and I agree the historical parallel is worth watching. Meta and TikTok native checkouts mostly did not stick, though Shop Pay has more ubiquity than Meta Pay ever did.

How to do SEO for Shopify in the age of AI search

SEO for Shopify in the age of AI search is having a renaissance because AI answer engines pull from the top 10 to 30 organic search results to answer questions, and structured data (schema markup) that used to be a nice-to-have is now how AI extracts your product facts with confidence. If you rank in traditional SEO and you have clean schema, you are the source AI cites.

Kurt’s SEO clients are focused on three moves. First, add rich structured data to product and collection pages so AI can extract facts cleanly. Second, slice broad collection pages into narrow long-tail collection pages (“men’s performance polos” instead of just “men’s tops”) to capture exact-match query phrases.

Third, use AI to write SEO titles, meta descriptions, and alt text at scale on catalogs that were too big to hand-edit before.

The AI-assisted SEO cleanup is what moved my own store’s organic traffic to an 18-year high this year. I wrote Python scripts that connect to my store’s API, find every product missing an SEO title or meta description, generate one using Google Shopping best practices, and generate alt text from the product photo plus description. A human still reviews every entry before it goes live, but the whole pass takes about an hour instead of weeks of data entry.

Kurt uses the same pattern on client stores. On a store with 1,000 products, generating and reviewing alt text on every image would previously never happen. With AI, it takes one afternoon and improves both accessibility and image search visibility at once.

The bare-bones Shopify apps Kurt Elster installs on every store

The bare-bones apps Kurt installs on every new Shopify store are first-party Shopify apps that live in the admin (Search and Discovery, Shopify Flow, Knowledge Base), plus one paid data tool (Matrixify), plus a small number of front-end AOV apps chosen based on the store’s specific pain points. He avoids apps that bloat front-end load time or duplicate what he can build in a Liquid section.

The reasoning is simple. Every front-end app you install adds page weight and a monthly fee, and rarely does one solve a problem that a small custom section could not. First-party admin apps are low risk because they only touch the admin, not the storefront.

The paid tool he swears by is Matrixify, which exports and imports pretty much everything in a Shopify store as a spreadsheet. That matters for AI workflows because a spreadsheet is what you feed into ChatGPT or Claude to bulk-edit product data, then re-import into Shopify. Bulk edits that used to take days can now take an hour.

The AOV app stack that works on Shopify in 2026

The AOV app stack Kurt recommends starts with a good cross-sell and upsell layer, adds a drawer cart with a free-shipping progress bar, layers on free-gift-with-purchase, and finishes with post-purchase upsells on the thank-you page. Once conversion basics are handled, AOV is where the compounding returns are.

His picks by function:

• Order editing: Cleverific Order Edit, so shoppers can fix their own orders and cut support tickets.
• Cross-sells and upsells: Zipify OneClickUpsell for pre and post-purchase; Rebuy for site-wide personalized recommendations.
• Free gift with purchase: Kurt is launching his own app for this. Free gift is his favorite promo because it lifts AOV without discounting the core product.
• Drawer cart: Slides out from the right on add-to-cart. Put a free-shipping progress bar, a “you’re $25 away from a free gift” progress bar, and related items inside it.
• Frequently bought together on product pages: Also good for internal linking and SEO.
• Post-purchase upsells: The single most successful post-purchase offer his agency has seen is “buy another one of what you just bought at 15% off, we’ll ship them together.” Especially strong for consumables.

The one caveat on the “buy another one” post-purchase upsell: run it during high-sale periods only, not 24/7/365. Merchants who run every winning promo year-round train buyers to expect the discount and destroy their margin.

Which Shopify AI features are overhyped?

The most overhyped Shopify AI features are the third-party AI apps that are thin wrappers around ChatGPT and Claude, charging 10x the underlying credit cost for a UI layer merchants could replicate themselves. When you use ChatGPT enough you start to recognize its writing syntax, and you notice it inside a lot of “AI” apps that charge $30 a month for what would cost $3 in API credits.

Kurt’s blanket rule: if the AI app is not doing something structurally hard that requires deep integration with the Shopify data model or with a hardware or workflow you cannot recreate, you are paying for a wrapper.

That does not mean every AI app is bad. Kurt loves several. It just means read the app description skeptically before paying for another middleman.

The other overhyped bucket is fully agentic browser-control AI (“tell an agent to go log into your Shopify store and fix a thing”). Proof-of-concept demos exist, they are rough, and neither Kurt nor I want an AI clicking around inside our store admin unsupervised yet. Wait for that one to mature.

Frequently asked questions

What are the top Shopify AI features in 2026?

The top Shopify AI features in 2026 are Shopify Sidekick (in-admin AI analytics assistant), AI block generation in the theme editor, AI live chat sales agents, AI-populated product recommendations using image embeddings, and Shopify Knowledge Base plus MCP for exposing your catalog to ChatGPT and Perplexity.

Does Shopify’s AI theme generator work?

Shopify’s full-theme AI generator is best treated as a starting point rather than a finished theme, and Kurt Elster describes the results as feeling random. The AI block generator inside the theme editor is much more useful and produces working widget code from a one-sentence prompt at no extra cost.

Do AI live chat agents actually increase Shopify sales?

AI live chat agents on Shopify do increase sales when they proactively engage shoppers on product pages with data-driven questions, and merchants running them report higher AOV from shoppers who interact. The catch is that the AI often self-scores tickets “resolved” when they are not, so audit conversation logs weekly.

How do I optimize my Shopify store for AI search engines like ChatGPT and Perplexity?

The way to optimize a Shopify store for AI answer engines is to rank in traditional Google SEO first (AI cites the top 10 to 30 organic results), add rich schema markup to product and collection pages so AI can extract product facts, install Shopify’s free Knowledge Base app to opt into the ChatGPT and Perplexity MCP integration, and slice broad category pages into long-tail collection pages that match specific search phrases.

What is the Shopify Knowledge Base app?

The Shopify Knowledge Base app is a free first-party Shopify app that exposes your product catalog to ChatGPT and Perplexity via Model Context Protocol, reports how many times AI answer engines recommended your products, and lets you write FAQ answers that AI models will use to answer shopper questions about your store.

What is the best post-purchase upsell on Shopify?

The single most successful post-purchase upsell Kurt Elster’s agency has seen is offering the shopper another unit of the product they just bought at 15% off, shipped together with the original order. It works best on consumable products, and you should run it only during high-sale periods to avoid training customers to always expect the discount.

Is Shopify Flow free?

Shopify Flow is free for all Shopify plans now, though it was originally a Shopify Plus-only feature. It is one of the highest-ROI first-party apps because it automates admin workflows (tagging, notifications, inventory triggers) that would otherwise chew up hours per week.
