Google just rewrote the rules for how retailers reach nearby shoppers. Starting August 31, 2026, Local Inventory Ads will turn on automatically across eligible Shopping campaigns. No more opt-in. No more manual toggle. The change lands with the force of a platform-wide policy shift.
Advertisers scramble to adapt before the August deadline
Search Engine Land first broke the news of the initial notification last week. Google is making Local Inventory Ads the default for eligible Shopping campaigns. The company followed up days later with official confirmation. “Starting Aug. 31, Google will automatically enable the “Local products” setting for every Shopping campaign,” the Google Ads Developer Blog stated plainly. Read the full announcement here.
The move aligns Shopping campaigns with Performance Max for Retail. Previously advertisers had to set the enable_local field to true in their campaign’s ShoppingSetting. Now the backend overrides that value to true regardless. And the legacy “Local products” dropdown vanishes from the Other settings section.
Control shifts instead to the Inventory filter. Advertisers specify Channel equals Online or Channel equals Local. This centralizes decision-making. It eliminates duplicate settings that once created overlapping controls. But the transition carries risks for teams that split budgets between digital and brick-and-mortar operations.
Common Thread Co spelled out the stakes for ecommerce brands. Online-only retailers face “invisible spend.” Budget quietly drains toward local results they never intended to promote. “For online-only brands, the real risk is invisible spend. A default setting change can quietly redirect budget before you notice the performance drop,” the agency warned in its analysis published four days ago. See their complete breakdown.
Omnichannel players encounter a different headache. Shared budgets pit online and in-store bids against each other inside the same campaign. Optimization signals blur. Cost per acquisition climbs. The agency advised setting distinct filters before the clock runs out. “Omnichannel brands that want to budget separately for in-store and online performance have a clear window before August 31 to get their campaign structure right. After that, cleanup is harder.”
Developers face code changes too. The Google Ads API v25.1 and newer will throw a ContextError.OPERATION_NOT_PERMITTED_FOR_CONTEXT if code tries to set enable_local to false on Shopping campaigns. Older API versions simply ignore the disable request and treat the value as true. Dora Sun of the Google Ads API Team signed the blog post that laid out these technical details.
Two clean workarounds exist. First, create a listing scope through CampaignCriterionService with product_channel set to ONLINE. Second, configure the Inventory filter inside the campaign settings UI to exclude local inventory. Either approach lets teams silo budgets and reporting by channel.
The update does not touch Performance Max or Demand Gen campaigns. The enable_local field keeps working there exactly as before. Google Support documentation already reflects the broader philosophy. Local inventory ads and free local listings let merchants showcase in-store stock to nearby searchers. Google’s official overview explains the add-on mechanics.
Retailers who feed local inventory data through Merchant Center must act fast. Verify the Local Inventory Ads add-on status under Growth > Manage programs. Review every linked Shopping campaign. Update filters or restructure budgets. Fail to move and campaigns could behave in unexpected ways after the August 31 cutoff. Spend leaks. Reports distort. Attribution breaks.
Barry Schwartz captured the early buzz at Search Engine Roundtable. He noted the email Google sent directly to affected manager accounts. “Local inventory ads will now be turned on by default in your Shopping campaigns. You can change this setting by using the “Inventory filter” instead of the “Local products” setting.” The post appeared five days ago. Full coverage at SERoundtable.
Industry chatter on X echoed the urgency. PPC specialists and agency leads shared the developer blog link within hours of publication. Some predicted wider adoption of local ads. Others warned of budget surprises for unprepared accounts. The conversation remains lively as the deadline looms.
This policy adjustment reflects Google’s long push toward unified retail advertising. The company wants merchants to treat online and offline inventory as one connected catalog. Defaulting to local promotion removes friction for stores that stock both channels. Yet it demands discipline from advertisers who once relied on the old binary switch.
Smart teams will audit now. They will segment campaigns where scale justifies separation. They will monitor local versus online metrics with fresh eyes once the filter becomes the only lever. Those who delay risk exactly the performance surprises Google itself flagged in its merchant notifications.
The clock ticks. August 31 arrives soon. Retail media buyers and Google Ads practitioners face a straightforward but consequential task. Update the structure. Or watch the platform decide for them.
