For a Shopify store with around 30 niche plant care products, what is the highest-impact area we should optimize first to improve visibility in Google Shopping, Google Search, and AI Overviews: product titles, product descriptions, GTINs/MPNs, Google product categories, structured data, or Merchant Center feed attributes?
Hello Molly, my name is Emmanuel, founder of FeedArmy, and your host for today’s Shopify AMA for Google’s AI Overviews.
To increase visibility in Google’s AI surfaces (AI Overviews, AI Mode, and conversational shopping), the highest-impact lever for products is your Google Merchant Center product data. Google’s AI shopping answers are built from the Shopping Graph, which is fed by your product feed, so the more complete and structured your data, the more accurately AI systems can understand, represent, and recommend your products when shoppers ask questions in natural language.
I’ve made a video guide covering this here: https://www.youtube.com/watch?v=p3Ay8iy8v0A
Start with these two established attributes:
Product Highlight [product_highlight] : short bullet-style selling points AI can quote directly: Product highlight [product_highlight] - Google Merchant Center Help
Product Detail [product_detail] : structured technical specs (section/name/value), ideal for spec-driven questions: Product detail [product_detail] - Google Merchant Center Help
Then add the new conversational attributes, which Google rolled out specifically to help AI systems and conversational agents understand product nuances. They’re optional, submitted via a supplemental feed, primary feed, or the Merchant API, and adding them won’t affect the approval status of your existing products:
Question and Answer [question_and_answer] : arguably the highest-leverage one. FAQ pairs in plain language directly match how people ask AI (“does it have a headphone jack?”). If your product pages already have FAQs, most of this data exists — it just needs mapping: Question and answer [question_and_answer] - Google Merchant Center Help
Variant Option [variant_option] : lets you declare variant dimensions beyond the standard color/size/material set (e.g. “graphics card”, “scent”, “wattage”), so AI doesn’t have to guess variant differences from titles. Used together with item_group_id: Variant option [variant_option] - Google Merchant Center Help
Item Group Title [item_group_title] : a clean shared title for the whole variant family, so AI can present the product group first, then drill into a specific variant: Item group title [item_group_title] - Google Merchant Center Help
Related Products [related_product] : declares accessories, spare parts, substitutes, “often bought with” relationships, which powers cross-sell answers like “what accessories work with this”: Related product [related_product] - Google Merchant Center Help
Document Link [document_link] : URLs to hosted PDFs (manuals, spec sheets, assembly guides, ingredient lists) that AI agents can reference for detailed questions your description doesn’t cover. Most valuable for electronics, appliances, furniture, tools: Document link [document_link] - Google Merchant Center Help
Popularity Rank [popularity_rank] : a 0–100 value ranking each product against the rest of YOUR catalog, helping AI answer “best” and “most popular” queries. Note this ranks your own products against each other, not against competitors, setting everything to 100 won’t help. Keep it updated as sales data changes: Popularity rank [popularity_rank] - Google Merchant Center Help
A few practical tips:
1. Don’t duplicate data, Google explicitly says not to repeat information already in description, product_highlight, or product_detail inside the conversational attributes.
2. Keep feed and landing page consistent, the details in your feed must match what’s shown on the product page.
3. If your catalog is large, start with your top-selling SKUs: question_and_answer and popularity_rank first, then variant_option + item_group_title if you sell variants.
And beyond these, aim for overall feed completeness, the full product data specification is here, and every accurately filled attribute is another fact AI systems can use: Product data specification - Google Merchant Center Help
And for structured data, ensure that you have added all the supported attributes, here is a list: Supported structured data attributes and values - Google Merchant Center Help
However, you should be focusing on all attributes for Google Merchant Center, not just the newest ones Google released. So do have a look at the full list of supported attributes here: Product data specification - Google Merchant Center Help
