Google is set to fundamentally alter how retail advertisers manage their omnichannel campaigns. Beginning August 31, the search giant will automatically enable Local Inventory Ads (LIAs) by default for all Standard Shopping campaigns linked to Google Merchant Center accounts that have the Local Inventory Ads add-on active.
As part of this major update, Google is retiring its legacy "Local products" campaign setting. In its place, the company is introducing a centralized "Inventory filter" designed to govern how local and online products are distributed and segmented.
This transition represents a significant shift in Google’s retail advertising ecosystem. For digital marketers and enterprise retailers who manage distinct budgets, bidding strategies, and ROAS (Return on Ad Spend) targets for online and physical storefronts, this update requires immediate attention. Failing to adjust campaign configurations before the August 31 deadline could result in sudden shifts in budget allocation, unintended ad spend, and disrupted performance metrics.
Main Facts: Understanding the Structural Changes
To understand the impact of this update, it is necessary to examine the technical mechanics of what is changing within the Google Ads and Merchant Center interfaces.
1. The Default Activation of Local Inventory Ads
Previously, when an advertiser linked a Google Merchant Center account containing local product feeds to a Standard Shopping campaign, Local Inventory Ads remained opt-in. Advertisers had to manually check a box to allow their physical, in-store inventory to appear in search results alongside their e-commerce offerings.
Starting August 31, this dynamic will reverse. If a Merchant Center account has the Local Inventory Ads add-on enabled, any linked Standard Shopping campaign will automatically opt-in to displaying local products.
2. Elimination of the Legacy "Local Products" Setting
For years, the gateway for controlling local ad distribution was a dedicated checkbox within the campaign settings menu of Google Ads, labeled "Enable ads for products sold in local stores." This setting is being completely phased out. Advertisers will no longer have a simple binary toggle switch at the campaign level to turn local inventory on or off.
3. Introduction of the Centralized "Inventory Filter"
To replace the legacy checkbox and streamline campaign creation, Google is elevating the "Inventory filter" as the primary control mechanism. Moving forward, if an advertiser wants to segment their campaigns by channel, they must use this filter to explicitly define the inventory source. The filter will rely on two primary attributes:
- Channel = Online: Restricts the campaign to displaying products available for purchase via the advertiser’s e-commerce website.
- Channel = Local: Restricts the campaign to displaying products available physically in brick-and-mortar locations.

- The Notification Window: Throughout mid-2024, Google began systematically alerting merchants and agency partners who utilize the Local Inventory Ads add-on in Merchant Center. These notifications served as an early-warning system, advising advertisers to audit their active Standard Shopping campaigns.
- The Runway Period: Between the initial notifications and late August, advertisers have been given a window to manually adjust their campaign settings to prevent automatic opt-ins. During this period, both the legacy setting and the new filter options coexist to facilitate migration.
- The Hard Deadline (August 31): On this date, Google will officially retire the legacy setting. Any Standard Shopping campaign that has not been explicitly restricted via the new Inventory filter—and is linked to an LIA-enabled Merchant Center—will automatically begin serving Local Inventory Ads.
Supporting Data: The Value and Context of Local Inventory Ads
To understand why Google is making LIAs the default experience, it is helpful to look at the broader shift toward omnichannel retail and consumer search behavior.
Local Inventory Ads are designed for brick-and-mortar retailers. When a user searches for a product on Google (e.g., "leather boots near me" or "electric drill"), an LIA display shows the product’s image, price, and—crucially—its real-time availability at a nearby physical store, along with the store’s distance from the searcher.

Data from Google and various retail studies highlight why local inventory has become a primary focus for search engines:
- High-Intent Searches: According to Google search data, searches for "open now near me" and "in stock near me" have grown exponentially over the last several years. Users conducting these searches have a high intent to purchase immediately.
- ROPO Effect (Research Online, Purchase Offline): Modern consumer behavior relies heavily on verifying stock online before driving to a physical retail store. A significant portion of retail sales are influenced by digital touchpoints, even if the final transaction occurs at a physical register.
- Click-Through and Conversion Efficiency: Advertisers utilizing LIAs often report higher Click-Through Rates (CTR) and stronger overall conversion metrics for local queries compared to standard Product Listing Ads (PLAs), as local ads provide immediate utility to nearby consumers.
By making LIAs the default state for eligible campaigns, Google is attempting to ensure that merchants do not miss out on local foot-traffic opportunities. However, this automation comes at the cost of granular control, forcing search marketers to adapt their budgeting structures.
Official Responses and Industry Insights
Google’s official communications present this update as a user-experience improvement aimed at simplifying campaign management.
Google’s Rationale
According to the notification emails sent to advertisers, Google’s primary objective is to "remove duplicate settings that previously controlled Local Inventory Ads."
Historically, managing local products across Merchant Center feeds and Google Ads settings created redundant controls. Advertisers had to enable the feature in Merchant Center, set up local feeds, and then navigate to Google Ads to check a specific box within each individual campaign. By consolidating these settings under a single, unified "Inventory filter," Google aims to simplify campaign creation and prevent configuration errors that could lead to local inventory failing to serve.
Industry and Expert Reactions
While Google frames the update as a simplification, search marketing professionals and PPC agency leads have expressed a mix of caution and strategic concern.
The primary point of friction is the loss of default segmentation. Many sophisticated retailers run separate budgets for e-commerce and physical store locations. E-commerce budgets are typically optimized to a strict online ROAS target based on direct website transactions. In contrast, local budgets are often optimized using store visit conversions, local store transaction data, or offline revenue multipliers.
When Google merges these capabilities by default, an advertiser’s online shopping campaign could suddenly begin spending budget on local clicks, shifting capital away from pure e-commerce sales. PPC experts emphasize that while simplification is beneficial for smaller merchants with basic setups, enterprise retailers must actively intervene to protect their bidding models.
Implications: Strategic and Operational Impact on Advertisers
The transition from a legacy checkbox to an inventory filter has several direct implications for search marketing strategies.
1. Risk of Unintended Spend and Budget Dilution
For retailers operating with constrained budgets, the automatic activation of LIAs could dilute online ad spend. If a campaign is optimized solely for online purchases, and it suddenly begins driving clicks to local store pages, the online conversion rate and measured ROAS may appear to decline. This occurs because local store visits and offline sales are not always tracked with the same immediacy or attribution models as online checkouts.
2. Disruption of Bid Strategies and Smart Bidding
Google’s Smart Bidding algorithms (such as Target ROAS or Maximize Conversion Value) rely heavily on historical conversion data. If a campaign’s traffic mix suddenly shifts to include a high volume of local clicks—which have different conversion paths and values than online clicks—the bidding algorithm may experience a learning phase, leading to temporary performance fluctuations.
3. Increased Need for Clean Feed Management
Because the new system relies entirely on the Merchant Center connection and the "Inventory filter," the accuracy of an advertiser’s product feeds becomes even more critical. If local feeds are inaccurate, or if the "Channel" attribute is mapped incorrectly, campaigns could serve ads for out-of-stock local items, resulting in a poor user experience and wasted ad spend.
Step-by-Step Action Plan for Retail Marketers
To prepare for the August 31 transition and maintain control over retail campaigns, advertisers should execute the following steps:
Pre-August 31 Action Checklist:
[ ] Step 1: Audit Merchant Center Add-Ons
Identify if the "Local Inventory Ads" add-on is active.
[ ] Step 2: Review Standard Shopping Campaigns
Locate campaigns where online and offline budgets must remain separate.
[ ] Step 3: Implement the New Inventory Filter
Explicitly set [Channel = Online] or [Channel = Local] in settings.
[ ] Step 4: Update Bidding and Attribution
Ensure store visits and offline conversions are correctly valued.Step 1: Audit Merchant Center and Google Ads Accounts
Identify which Google Ads accounts are linked to Merchant Center accounts that have the "Local Inventory Ads" add-on enabled. If you do not run local stores or have no intention of running LIAs, verify that the add-on is disabled in Merchant Center to prevent automatic opt-ins.
Step 2: Segment Budgets Using the New Inventory Filter
For campaigns where you want to maintain a strict separation between online and offline budgets:
- Navigate to the Settings tab of your Standard Shopping campaign in Google Ads.
- Locate the Inventory filter section.
- Apply a filter using the Channel attribute.
- Set the filter to Channel = Online if the campaign should only drive e-commerce sales.
- Create a separate, dedicated campaign with the filter set to Channel = Local if you want a dedicated budget for driving foot traffic to physical stores.
Step 3: Adjust Smart Bidding Targets
If you decide to let online and local inventory run together in a unified campaign, ensure your Smart Bidding strategy is set up to value both actions. You should assign an appropriate monetary value to "Store Visits" or "Store Sales" conversions so the bidding algorithm can optimize for the true omni-channel value of the traffic.
Step 4: Monitor Performance Post-August 31
In the days and weeks following the August 31 deadline, closely monitor your Standard Shopping campaign performance. Analyze the "Segment" report by "Click Type" and "Device" to ensure that local clicks are not consuming an disproportionate share of your budget, and verify that your ROAS targets remain stable.
