A common sentiment in the SEO industry right now is that improving visibility within Google's AI surfaces is the most direct way to influence product discovery.

That thinking comes from a pretty clear reality: LLMs and AI-assisted shopping experiences — AI Mode, AI Overviews, Gemini — use the Google Shopping Graph as grounding data to surface product citations. [3] Unlike Bing, where the relationship between product feeds and LLM visibility is still being worked out, Google has been explicit about this. The Shopping Graph is the connective tissue between your Merchant Center feed and every AI-powered shopping experience Google offers.

Google has also been consistent in saying that optimizing for AI Mode and Gemini doesn't require a fundamentally different approach. The focus is on providing rich, accurate, and consistent product data through Merchant Center. With AI Overviews pulling increasingly from product feeds, ecommerce teams that treat the Merchant Center feed as a first-class SEO asset are the ones best positioned for what's coming.

We've spent considerable time over the past few months looking at how Merchant Center operates within this new AI context, and what stores can actually do with their feeds to show up in LLMs and AI-powered shopping surfaces.

How Google AI Mode Is Changing Product Discovery

Google AI Mode isn't just a new tab. It's a shift from keyword-led search into conversational product discovery. [3] Shoppers are no longer typing "waterproof hiking boots size 10." They're asking questions, refining with follow-ups, and browsing visual panels that update in real time.

The Shopping Graph powering this experience contains more than 50 billion product listings, with 2 billion updated every hour. [3] Three layers work together to make it run:

Layer	What it is	How it works in AI Mode
Gemini	Google's AI reasoning model	Interprets longer, more specific shopping prompts and understands intent, constraints, and follow-up questions
Query fan-out	Google's method for expanding one question into multiple related searches	Breaks a shopping prompt into subtopics: category, use case, price, material, reviews, availability
Shopping Graph	Google's product dataset	Connects AI Mode to 50B+ product listings, matching products to relevant AI queries using feed signals

Here's a concrete example. A shopper searching for a "cute travel bag" might see a browsable panel of images and listings rather than a standard results page. If they add context — say, a rainy trip to Portland — AI Mode expands the query to account for waterproof materials, easy-access pockets, and carry-on dimensions, then updates the panel accordingly. [3]

The implication for ecommerce teams is direct: incomplete feeds miss relevant sub-searches, even when a product technically matches what the shopper wants. Query fan-out means Google isn't just matching your title to a keyword. It's matching every attribute in your feed to a whole cluster of related queries.

Your Merchant Center Feed Is Now Your Most Important SEO Asset

In AI-powered shopping results, your product feed does a lot of the work your category pages used to handle in traditional SEO. Merchant Center uses product attributes to understand what you sell, match products to queries, and show accurate details in ads and free listings. [3]

Incomplete or inaccurate data creates issues in Merchant Center and can prevent products from appearing in AI surfaces at all. That's not just an advertising problem. It's an organic visibility problem.

The Product Attributes Google AI Weighs Most Heavily

These are the attributes that most directly affect whether your products surface in conversational queries:

Attribute	Why it matters for AI shopping discovery
Title	Helps Google understand the item quickly. Specific titles should include the product type and the most useful distinguishing details.
Description	Gives Google context about use case, features, material, fit, compatibility, or intended audience.
GTIN, Brand, MPN	Help Google identify the exact product and avoid confusion with similar items. Accurate brand and GTIN data helps products get categorized correctly.
Price	Must match the landing page and stay current. Mismatched prices are a common disapproval trigger.
Availability	Tells Google whether the product is in stock, out of stock, on preorder, or backorder.
Image Link	Supplies the main product image for ads and free listings. High-quality images, ideally at or above 1500 x 1500 px, perform best.
Google Product Category & Product Type	Help Google classify the item and place it correctly in shopping results.
Variant Attributes	Color, size, material, gender, and age group help Google match products to specific conversational searches.

AI shopping discovery is broader than traditional keyword matching. A shopper might describe a scenario, a problem, a budget, or a comparison between options. That creates a bigger job for product data. If that information isn't in the feed, the product may be technically eligible but largely invisible in richer discovery experiences. [6]

Google Shopping Free Listings and AI Visibility

Google's free listings are the organic counterpart to Shopping ads. They show up across the Shopping tab, Google Search, Google Images, and increasingly inside AI Mode and AI Overviews.

The key difference from paid Shopping ads: free listings are driven entirely by feed quality and Merchant Center compliance, not by bid strategy. That makes them particularly important for ecommerce teams focused on organic AI SEO.

Free listings are on by default in Merchant Center Next, but approval doesn't guarantee visibility. Feed completeness, pricing accuracy, and GTIN coverage all affect whether approved products actually show up. [6]

Checking Your Free Listings Status

Inside Merchant Center, the Programs section lets you confirm your products are opted into free listings. It's an easy thing to miss, especially when taking over a new client account. Google has a dedicated toggle for this. If products aren't appearing in Shopping results despite being approved, checking this setting should be the first step.

There's also an ongoing question in the industry about whether running Shopping ads influences free listing traffic volume. Google hasn't publicly confirmed any such relationship. But the practical recommendation stays the same: keep your feed complete, get your products approved, and make sure the free listings program is enabled.

Google Merchant Center's New AI Performance Insights Report

In July 2026, Google began piloting an AI performance insights report for select US Merchant Center accounts. [4] It's the first time Google has given merchants a native window into how their brands and products surface inside AI Mode, AI Overviews, and Gemini.

The report lives under Analytics > Products > AI performance. It's currently limited to a small set of US accounts, with Australia, Canada, India, and New Zealand coming in the months ahead.

All four metrics are impression-based:

Metric	What it measures
Share of Voice	Your AI impressions divided by total impressions across you and your competitors for related queries
Competitors' average share	The share of voice captured by your defined competitor set
Query frequency	How popular specific query types, product terms, and shopping journey phases have been
Query type	How a query was phrased: by category, product specs, reviews, etc.

This report covers organic AI traffic only — paid Shopping ads are excluded. There's also no click metric, which means Share of Voice should be treated as a leading indicator, not a performance KPI. [4]

The practical takeaway: merchants with complete, well-structured Merchant Center feeds are best positioned to earn Share of Voice in AI surfaces. The report is a measurement tool. The optimization work happens in the feed.

Universal Commerce Protocol (UCP) and Conversational Attributes

Two developments are reshaping how product data flows into AI shopping experiences, and both are worth paying attention to now.

Universal Commerce Protocol (UCP) is an open standard Google launched in January 2026, co-developed with Shopify, Target, and other retail partners. [7] It enables direct purchases across AI surfaces like AI Mode and Gemini, essentially letting AI agents complete checkout on behalf of shoppers. For merchants, UCP readiness starts with a clean, complete Merchant Center feed — the same foundation that powers free listings and AI Overviews.

Conversational Attributes are a new set of data attributes in Merchant Center built specifically for discovery in conversational commerce, on surfaces like AI Mode. [8] They let merchants add richer product context — use cases, compatibility notes, style descriptions — that AI systems use to match products to conversational queries. Conversational Attributes are already rolling out globally, making them one of the most actionable feed optimizations available right now.

The asymmetry here is worth noting. The input side (Conversational Attributes) is global today. The output side (AI Performance Insights reporting) is still US-only in pilot. Merchants who invest in feed quality and conversational attributes now will be ready to act on their AI visibility data the moment reporting reaches their market.

The Solution: SuggestAPI's Google Shopping Feed Export

Keeping a catalog complete, accurate, and synchronized with Google Merchant Center is genuinely hard. Product data lives in multiple systems. Prices and availability change constantly. Manual feed exports go stale fast.

SuggestAPI handles this by publishing a Google Merchant Center-compatible product feed directly from your search index. [5] The same catalog SuggestAPI already indexes for search powers your Merchant Center feed — so your search index and your feed stay in sync without any extra work.

Implementation guide. For step-by-step setup — feed URL format, Merchant Center connection, attribute mapping, and catalog prerequisites — follow the SuggestAPI docs: Google Shopping Feed Export. Related ingestion paths are covered in Bulk Imports and Ingestion Jobs.

How the Feed Works

Each verified domain gets a public feed URL:

https://feed.suggestapi.com/{domain}/

For example:

https://feed.suggestapi.com/shop.example.com/

Point Google Merchant Center at that URL as a scheduled product feed (RSS/XML). The feed is cached for up to 24 hours, so newly indexed products appear after Google's next fetch cycle.

Connecting Google Merchant Center

The setup is straightforward:

Confirm the feed URL loads in a browser or with curl and returns valid XML.
In Google Merchant Center, add a scheduled product feed.
Choose the RSS/XML feed type and paste your https://feed.suggestapi.com/{domain}/ URL.
Set a fetch schedule that matches how often your catalog changes.
Review Google's diagnostics for missing attributes or disapproved items.

Full Merchant Center connection steps, including caching behavior and diagnostics tips, live in the Google Shopping Feed Export guide.

Attribute Mapping

SuggestAPI maps required product attributes from your linked index into Google Shopping fields automatically. Items missing any required attribute are omitted from the feed rather than published incomplete — so Google always receives a valid, well-formed feed.

Google Attribute	Common Source Fields	Notes
`g:id`	`id`, `external_id`	Stable product identifier
`title`	`title`
`description`	`description`, `desc`
`link`	`link`, `url`, `product_url`	Must be an `http://` or `https://` URL
`g:image_link`	`image_link`, `image_url`, `featured_image`, `thumbnail`	Must be an `http://` or `https://` URL
`g:availability`	`availability`, `stock_status`, `in_stock`	Normalized to `in_stock`, `out_of_stock`, `preorder`, or `backorder`
`g:price`	`price`, `currency_code`	Formatted as amount and ISO currency, e.g. `89.99 USD`

Additional attributes are included when present: g:condition, g:brand, g:gtin, g:mpn, and optional fields like sale_price, color, size, material, google_product_category, item_group_id, and custom_label_0 through custom_label_4. [5]

Prerequisites

A feed becomes available when three conditions are met:

The domain is a normalized hostname, such as shop.example.com.
Domain ownership is verified in SuggestAPI.
The domain is linked to a search index that contains your catalog.

Shopify and other commerce integrations that verify ownership and link a domain to an index are usually enough for the feed URL to become available. Which products appear still depends on catalog completeness.

Keeping the Catalog Complete

Documents need to land in the domain's linked index with the required fields. You can load them via inline document ingestion (POST /v1/indexes/{index_id}/documents), Google Shopping CSV import (POST /v1/indexes/{index_id}/import/google-shopping), or bulk ingestion paths covered in the SuggestAPI bulk imports docs. [5]

Keeping product IDs stable matters: updates overwrite cleanly, Google sees consistent g:id values, and price or availability changes show up accurately on the next feed fetch.

Other Considerations

As AI shopping surfaces keep maturing, the connection between feed quality and AI visibility will only get tighter. Google's AI Mode is already expanding query fan-out to include use-case language, comparison attributes, and compatibility signals — all of which depend on what's in your Merchant Center feed.

For ecommerce teams already using SuggestAPI for site search, the Google Shopping Feed Export is a natural extension. The same catalog powering your on-site search experience can now power your Merchant Center feed, your AI Overviews visibility, and your Gemini product discovery — all from one source.

Getting started comes down to a short checklist:

Verify your domain in SuggestAPI and confirm it's linked to a search index.
Confirm the feed URL returns valid XML.
Add the feed as a scheduled RSS/XML feed in Google Merchant Center.
Set a fetch schedule aligned with your catalog update frequency.
Review Merchant Center diagnostics and resolve any disapprovals or missing attributes.
Enable Conversational Attributes in Merchant Center to improve AI Mode discovery.
Configure your competitor set in Merchant Center so the AI Performance Insights report is meaningful when it reaches your account.

The foundation of AI ecommerce SEO hasn't changed: accurate, complete, and consistent product data. SuggestAPI makes that foundation easier to maintain.
