The Evolution of Automotive Retail in the Digital Space
The landscape of automotive sales has undergone a seismic shift over the last five years. Moving away from the traditional model where a customer spends hours on a physical lot browsing rows of pre-assembled cars, the industry is pivoting toward a digital-first approach. In response to this shift, Google has introduced a significant update to its Merchant Center: the “build to order” availability value for vehicle listings.
This update represents a major milestone for automotive digital marketing. Historically, Google Merchant Center (GMC) was designed for retail products—items that are either in stock, out of stock, or available for backorder. Vehicles, however, are high-ticket, complex items that don’t always fit into these neat boxes. By adding a specific “build to order” attribute, Google is finally acknowledging the reality of modern car buying, where customization and factory orders are becoming the standard rather than the exception.
What Is the New “Build to Order” Attribute?
The “build to order” attribute is a new value within the `availability` field in Google Merchant Center. It is specifically designed for vehicle sellers who offer cars that are not currently sitting in their physical inventory but can be manufactured or configured based on a buyer’s specific preferences.
When a dealer or manufacturer uses this attribute, they are signaling to Google—and by extension, to potential car buyers—that while the car isn’t ready for immediate pickup today, it is available for purchase and subsequent production. This bridges the gap between “In Stock” and “Out of Stock,” providing a third option that accurately describes the lead-time nature of custom automotive sales.
Technical Requirements: Updating Your Feed and Structured Data
For automotive digital marketers and SEO specialists, implementing this change requires a two-pronged approach. Google demands strict consistency between what is presented in your data feed and what is coded into your website’s structured data (Schema).
1. Updating Google Merchant Center Feeds
Within your primary or supplemental feed in Google Merchant Center, you must now utilize the specific string `build to order` in the `availability` attribute column. This tells Google’s indexing engine how to categorize the vehicle’s availability status in Google Vehicle Ads and organic listings.
2. Aligning Structured Data (Schema.org)
To ensure Google validates your listings, your website’s landing pages must also reflect this status using Schema.org markup. The specific value to use in your structured data is `BuildToOrder`.
Failure to align these two data points can lead to account warnings or item disapprovals. Google uses a sophisticated crawling mechanism to “fact-check” your feed against your website. If your feed says a car is “build to order” but your website Schema says it is “in stock” (or lacks availability data entirely), the discrepancy may cause the listing to be pulled from the platform.
The “New” Vehicle Requirement: A Critical Distinction
One of the most important caveats to this update is the relationship between the `availability` and `condition` attributes. Google has made it clear: the “build to order” status is exclusively for new vehicles.
In the Google Merchant Center ecosystem, every vehicle must have a `condition` attribute, typically set to “new” or “used.” Because a “build to order” vehicle is, by definition, a car that has not yet been manufactured or is being assembled to a customer’s specifications, it cannot be considered a used vehicle.
If a seller attempts to list a vehicle as “used” while simultaneously marking it as “build to order,” the listing will be automatically disapproved. This is a logical safeguard to prevent confusion in the marketplace; pre-owned vehicles exist in a finished state and cannot be “built to order” in the factory sense.
Why This Update Matters for the Automotive Industry
The introduction of “build to order” isn’t just a technical tweak; it is a response to how the automotive world has changed since the global supply chain disruptions of 2020 and 2021.
Catering to the Direct-to-Consumer (DTC) Model
Companies like Tesla, Rivian, and Lucid have pioneered a model where physical inventory is minimal. Instead of lots full of cars, they have “showrooms” where customers view a demo model and then place an order online for a custom-built vehicle. Legacy automakers like Ford, GM, and BMW are increasingly adopting this “order-to-delivery” model to reduce overhead and inventory costs. The “build to order” attribute allows these brands to list their entire configurable catalog on Google without misleading customers into thinking a car is ready for same-day delivery.
Improving User Experience and Trust
There is nothing more frustrating for a car shopper than clicking on an ad for a specific trim and color, only to find out the dealer doesn’t actually have it on the lot. By labeling these as “build to order,” dealers set realistic expectations. Shoppers understand they are entering a configuration and ordering process rather than a traditional purchase-and-drive transaction. This transparency builds trust and reduces bounce rates on dealership websites.
Data Cleanliness for Google
From Google’s perspective, this update improves the quality of their search results. By segmenting immediate inventory from custom orders, Google can provide more relevant ads to users. A user searching for “cars for sale near me” might be prioritized for in-stock inventory, while a user searching for “custom 2025 Ford F-150 configuration” might see “build to order” listings.
Implementation Best Practices for Dealers and Agencies
If you are managing vehicle listings for a dealership or a multi-brand automotive group, there are several best practices to follow to ensure a smooth rollout of the “build to order” attribute.
Audit Your Current Inventory Feeds
The first step is to identify which models in your catalog are actually available for factory orders versus those that are only sold from the lot. Many dealerships have a mix of both. You may need to create a supplemental feed in GMC to apply the `build to order` status to specific VINs or model codes that fall into the custom-order category.
Synchronize with Your Website Provider
Most dealerships use third-party website providers (like Dealer.com, Sincro, or CarsforSale.com). You must ensure that these providers have updated their Schema.org implementations to support the `BuildToOrder` value. If your website provider is lagging, your GMC feed updates might actually trigger disapprovals because the structured data on the page won’t match the feed.
Monitor Merchant Center Diagnostics
After implementing the changes, keep a close eye on the “Diagnostics” tab in Google Merchant Center. Look for any “Mismatched value (page crawl)” errors. These will tell you exactly where your feed and your website are out of sync.
The Role of Google Vehicle Ads (VAs)
This update is particularly relevant for Google Vehicle Ads, the specialized ad format that appears at the top of Google Search results. Vehicle Ads are powered by the Google Merchant Center feed.
Before this update, dealers who wanted to promote custom orders often had to use standard Search Ads (text-based) because the Vehicle Ads format was heavily reliant on specific inventory. Now, dealers can use the more visual, high-converting Vehicle Ads format to promote their “build to order” programs. This levels the playing field, allowing smaller dealers to compete with larger ones that might have more physical inventory on hand.
A Look Back: How We Got Here
The credit for first spotting this update goes to Google Shopping specialist Emmanuel Flossie, who highlighted the change on his FeedArmy blog. The update reflects a broader trend of Google maturing its “Shopping” features to accommodate specialized industries.
Previously, the `availability` attribute only supported `in_stock`, `out_of_stock`, `preorder`, and `backorder`. While `preorder` was occasionally used for upcoming vehicle releases, it didn’t quite fit the “build to order” scenario where a vehicle is already released but requires custom assembly. The addition of this fifth value shows that Google is listening to the specific needs of the automotive sector.
Future Outlook: Is the Car Lot Becoming Obsolete?
While the “build to order” attribute is a win for digital efficiency, it also raises questions about the future of the traditional dealership. As more consumers become comfortable ordering vehicles online—and as Google makes it easier to find and configure these vehicles through Search—the pressure on dealerships to maintain massive, expensive physical inventories may decrease.
Instead, the dealership of the future may focus more on:
- Providing test-drive experiences for “demo” models.
- Facilitating the digital ordering process.
- Handling the delivery and service of custom-ordered vehicles.
Google’s infrastructure is clearly moving in this direction. By refining how vehicle availability is tracked and displayed, they are positioning themselves as the primary “digital showroom” for the global automotive market.
Summary of Key Takeaways
To wrap up, here are the essential points that vehicle sellers need to know about the new “build to order” attribute:
- New Attribute Value: Use `build to order` in your GMC feed and `BuildToOrder` in your website’s structured data.
- Consistency is Key: Discrepancies between your feed and your website crawl will result in disapproved listings.
- “New” Vehicles Only: You cannot use this attribute for used or certified pre-owned (CPO) vehicles.
- DTC Friendly: This is a major advantage for direct-to-consumer brands and dealers offering factory customization.
- Better Expectations: It helps manage customer expectations regarding delivery times and physical availability.
For automotive marketers, the message is clear: it’s time to update your feeds. As the industry moves further away from the “lot-only” model, having your digital data reflect the reality of your sales process is no longer optional—it’s a competitive necessity. By embracing the “build to order” attribute, you can ensure your vehicles are visible to the right customers at the right time, with the right expectations set from the very first click.
