Google changes default Local Inventory Ads behavior

Google is shifting how search marketers manage Local Inventory Ads in Standard Shopping campaigns. Beginning August 31, Google will automatically enable Local Inventory Ads (LIAs) by default for any eligible Shopping campaign linked to a Google Merchant Center account that has the Local Inventory Ads add-on active. Along with this default behavior change, Google is phasing out a legacy campaign setting and replacing it with a more streamlined inventory filter.

This update represents a structural change in how multi-channel retailers control where their ad budget goes. For digital advertisers who run carefully separated campaigns for online e-commerce versus physical, in-store inventory, this shift requires immediate attention to avoid unexpected shifts in ad spend and campaign performance.

The Mechanics of the Update: What Is Changing on August 31?

Currently, setting up and managing Local Inventory Ads within a Standard Shopping campaign involves a specific checkbox and toggle configuration. However, Google is removing these overlapping layers to streamline its dashboard operations. Here is exactly what will happen when the update goes live:

Automatic Opt-In: If your Google Merchant Center account has the Local Inventory Ads add-on enabled, any linked Standard Shopping campaign will automatically opt into displaying local inventory ads by default.
Removal of “Local Products” Setting: The dedicated “Local products” toggle found under “Other settings” in the Google Ads campaign creation and settings menu will be permanently retired.
Inventory Filter Migration: Instead of the legacy toggle, advertisers must now use the “Inventory filter” to manage their inventory distribution. This filter allows you to segment your campaigns using the distinct attributes: Channel = Local or Channel = Online.

The upcoming change was first spotted by PPC specialist Arpan Banerjee, who shared a notification email sent by Google to affected Google Ads manager accounts. Marketers who oversee multi-location retail accounts must prepare for this timeline to ensure their budgets remain properly allocated.

Understanding Local Inventory Ads (LIAs) and Their Role in Retail

To understand the impact of this change, it helps to look at the value Local Inventory Ads bring to modern omnichannel retail. Unlike standard Google Shopping Ads, which send searchers directly to an e-commerce website to make an online purchase, LIAs are designed to drive physical foot traffic to brick-and-mortar storefronts.

When a consumer searches for a product nearby—for example, “running shoes near me” or “electric drill in stock”—a Local Inventory Ad can appear. These ads display crucial local store information, such as:

Real-time in-store availability (e.g., “In stock,” “Limited availability,” or “Out of stock”).
The physical distance to the nearest retail location holding the item.
The store’s current operating hours.
Special localized purchasing options, such as “Curbside pickup” or “Buy online, pick up in store” (BOPIS).

Clicking on a Local Inventory Ad typically directs the user to a Google-hosted local storefront page or the retailer’s own website featuring local store availability. This bridge between online research and offline purchasing is critical for brick-and-mortar success, as modern buyers often research product availability online before leaving their homes.

Why This Default Behavior Shift Matters to Retail Advertisers

While simplifying campaign setup sounds positive on paper, making LIAs “on by default” poses strategic challenges for retail media buyers. Here is why this update requires careful planning before the August 31st deadline:

1. Unexpected Budget Allocation Shifts

If you have the LIA add-on active in your Merchant Center but have kept LIAs disabled in certain high-performing online-only Shopping campaigns, those campaigns will begin serving local ads automatically after August 31. This can dilute your e-commerce budget by spending money on driving store visits rather than direct online sales—a change that could disrupt your established Return on Ad Spend (ROAS) targets.

2. Bidding and Bidding Strategy Disruptions

In-store conversions and online sales have vastly different values, profit margins, and sales cycles. Many sophisticated advertisers run separate online and local campaigns because they use different Smart Bidding strategies or target ROAS metrics for each. By combining these channels by default, Google could blend these performance signals, potentially leading to sub-optimal automated bidding decisions if the campaigns are not properly segmented beforehand using the new inventory filters.

3. Data and Feed Synchronization Issues

Running Local Inventory Ads requires a highly accurate, frequently updated local product inventory feed. If a campaign suddenly starts serving local ads for a location with outdated inventory data, shoppers might see ads for products that are actually out of stock. This leads to a poor customer experience, wasted ad spend, and potential complaints at the physical customer service desk.

Step-by-Step Action Plan to Prepare for the August 31st Deadline

To prevent unwanted campaign changes and budget shifts, search marketers should audit their Google Ads and Merchant Center accounts. Use this step-by-step checklist to ensure a smooth transition:

Step 1: Audit Your Merchant Center Add-ons

Check if your Google Merchant Center accounts have the “Local Inventory Ads” program enabled. If you do not have physical stores, or if you do not actively maintain a local product inventory feed, this update may not affect you. However, if the add-on is active, proceed to audit your Google Ads campaigns.

Step 2: Review Your Shopping Campaign Configurations

Identify all active Standard Shopping campaigns. Check which of these campaigns currently have the legacy “Local products” setting disabled. Make a list of campaigns that are dedicated strictly to e-commerce (online) sales versus those that are meant to drive physical store visits.

Step 3: Implement the New Inventory Filters

To maintain your existing campaign segmentations, do not wait for the automatic migration. Transition your campaigns to the new Inventory Filter configuration manually. Go to your campaign settings, locate the Inventory Filter options, and explicitly define your targeting parameters:

For online-only e-commerce campaigns, apply the filter: Channel = Online.
For local-only store visit campaigns, apply the filter: Channel = Local.
If you want a unified campaign that dynamically serves both, you can leave the filter open, but ensure your budgeting and bidding models are prepared for mixed traffic types.

Step 4: Monitor and Adjust Your Budgets

Keep a close eye on your campaign performance, especially in the first two weeks following the August 31st rollout. Watch for sudden shifts in impressions, click-through rates (CTR), and conversion types (e.g., an influx of store visits relative to online transactions). Adjust your daily budgets and bidding thresholds accordingly to stabilize performance.

The Broader Picture: Google’s Push Toward Automation and Simplification

This update is not an isolated change; it is part of a broader, years-long effort by Google to simplify campaign creation and rely more heavily on automation. By removing the “Local products” toggle and integrating it directly into standard inventory filters, Google is reducing the number of manual switches advertisers have to manage.

We see similar patterns across the Google Ads ecosystem, notably with the rise of Performance Max (PMax) campaigns, which combine search, display, maps, discover, and shopping formats into a single, machine-learning-driven campaign type. By making local inventory capabilities a default standard in Shopping, Google is encouraging retail brands to adopt a unified omnichannel perspective rather than viewing digital and physical sales as completely separate silos.

While automation can improve efficiency for smaller businesses that lack the resources to build complex campaign structures, enterprise brands and agencies often prefer granular control. Utilizing the Channel = Local or Channel = Online inventory filters remains the best way to maintain that granular control within Standard Shopping campaigns.

Best Practices for Running Successful Local Inventory Ads

As LIAs become more deeply integrated into standard campaign settings, now is the perfect time to optimize your local retail search strategy. If you plan to embrace the default behavior and leverage LIAs to drive physical foot traffic, keep these best practices in mind:

1. Keep Your Local Feeds Updated

The success of your LIAs depends entirely on the accuracy of your local product inventory feed. Ensure you submit your inventory data to Google Merchant Center at least once a day—or more frequently for high-volume retail locations. Utilizing Google’s local inventory feed tools or integrating directly via an API can prevent ads from showing for out-of-stock items.

2. Promote Store Pickup Options

Ensure that your local inventory ads display “Pickup Today” or “Curbside Pickup” badges. Shoppers value convenience, and knowing they can secure an item immediately and pick it up on their way home can significantly increase your click-through and local store conversion rates.

3. Use Store Visit Conversions and Local Actions

To accurately measure the return on your LIA spend, you must track offline conversion signals. Ensure your Google Business Profiles are linked to your Google Ads account, and monitor metric columns like “Store Visits,” “Local Actions” (such as driving directions and phone calls), and “Local Conversions.” This data is vital for proving the omnichannel impact of your marketing efforts to stakeholders.

Final Thoughts

Google’s transition to making Local Inventory Ads a default behavior starting August 31st underscores the growing importance of omnichannel retail strategy. While the removal of the legacy “Local products” setting might seem minor, the resulting shift in campaign spend and bidding behavior could surprise unprepared advertisers.

By auditing your Merchant Center settings and proactively applying the new “Channel” inventory filters, you can protect your digital marketing budgets, ensure accurate reporting, and continue serving highly targeted ads to both online shoppers and local in-store buyers alike.
