Google's EU Data Ruling: What WooCommerce Stores Must Know

If your WooCommerce store gets most of its traffic from Google Shopping and Google’s AI-powered product discovery tools, you are building on ground that regulators are actively digging up. The European Commission adopted two legally binding Digital Markets Act decisions on 16 July 2026. One forces Google to open Android system functions to rival AI assistants, ending Gemini’s preferential access, and the other requires Google to share anonymised search ranking, query, click, and viewing data with competing search engines and qualifying AI chatbots. Data sharing starts in January. These are binding orders with a compliance deadline.

The immediate effect on your store is indirect but real. Google has built its dominance in product discovery partly on exclusive access to the search intent data those orders now open up. When a shopper types “waterproof walking boots under £80” into a search engine, the click patterns, ranking signals, and query data that Google uses to surface relevant product results will, under these rulings, be available to rivals on fair and non-discriminatory terms, meaning Perplexity, ChatGPT’s shopping features, and other AI-enabled platforms will be able to build product discovery tools using the same quality of intent signal that Google has held exclusively until now.

The Android angle compounds this considerably. 60% of EU users have an Android device, and until now those users faced real friction when trying to install and use a rival AI assistant as their default, because Gemini had preferential access to system-level Android functions. The Commission found that third-party AI assistants were limited in how they could offer their services on those devices, and that users should be able to choose an assistant without losing features. Once that friction is removed, a meaningful share of mobile shoppers may start their product searches through an AI assistant that has no existing relationship with your Google for WooCommerce product feed.

Your Google for WooCommerce feed was built for one platform’s rules

The Google for WooCommerce plugin, available from the WordPress plugin directory, connects your store’s product catalogue directly to Google Merchant Center. It maps your WooCommerce product data, titles, descriptions, prices, availability, and GTINs, to Google’s feed specification and handles the sync automatically. That integration is well-built and, for EU merchants selling through Google Shopping, it works. The problem is that it is a single-platform integration designed around Google’s data requirements and Google’s ranking logic, so if a shopper’s AI assistant of choice is pulling product results from a platform that does not receive your feed, your products simply do not appear.

As rivals gain access to Google’s search intent data and build their own shopping layers on top of it, they will develop their own feed specifications, their own structured data requirements, and their own ranking criteria. A product catalogue optimised exclusively for Google’s attribute requirements, using Google’s preferred title format and Google’s condition taxonomy, may not map cleanly to what those platforms need. The plugin’s Feed Rules section lets you remap product attributes and apply conditional logic to what gets sent to Google, but it has no output for Bing Shopping, no connection to Perplexity’s product index, and no awareness of what a third-party AI assistant might require. If the search landscape fragments, the feed strategy needs to fragment with it.

What a more fragmented product discovery environment means for ad spend

Google’s president of global affairs, Kent Walker, argued publicly that the decisions risk undermining privacy and security guardrails for millions of Europeans, and Google will almost certainly challenge the rulings. That process takes time. The direction of travel is established, though, and merchants who wait for the outcome before adjusting their strategy are making a bet on Google’s legal position rather than on their own resilience.

The merchants most exposed are those running lean setups: a single Google product feed, Performance Max campaigns as the primary paid channel, and no structured data beyond what the Google for WooCommerce plugin outputs. That configuration made sense when Google controlled the discovery journey. The retail media implication identified by InternetRetailing’s analysis is that Google has been the default gateway to agentic commerce, the AI-mediated shopping journey where an assistant finds, compares, and presents products on behalf of the user. If that gateway opens to rivals, the ad spend and feed investment concentrated in one platform will need to be distributed across several, bringing higher operational complexity and, for stores not built to publish structured product data to multiple destinations, gaps in coverage from day one.

Product data quality is the consequence that tends to go unconsidered. When you feed one platform, you can tolerate some inconsistency in your WooCommerce product attributes because Google’s system compensates. Feed four platforms with different validation rules, and missing GTINs, inconsistent condition fields, or truncated descriptions that Google overlooked will cause rejection errors across the board. The data quality problem that has always existed in your catalogue becomes visible at exactly the moment you need the broadest reach.

If your current traffic and product feed strategy is built around Google alone, now is the time to find out whether it can perform across a more fragmented search environment. I work with WooCommerce store owners to audit product feed configuration, structured data output, and multi-platform readiness. With Google’s data-sharing obligations taking effect in January, the window to get ahead of this is short. Get in touch at The WordPress Guy to book a feed and visibility audit for your store.
