Google Ads continues to expand the capabilities of Promotion Assets, introducing new promo code formats that fundamentally change how advertisers deliver promotional offers across channels. In January 2025, Google announced barcode and QR code options alongside traditional promo codes, creating a more versatile toolkit for marketers running sales, discounts, and special offers.
These additions recognize that modern consumer journeys span digital and physical environments, requiring promotional mechanics that work seamlessly across both. When combined with effective bid strategy optimization, these new formats help advertisers create cohesive campaign approaches that drive measurable results. This guide explores the fundamentals of these new formats, provides implementation best practices, and examines how data-driven advertisers can leverage them to improve campaign performance.
What Are Promotion Assets in Google Ads
Promotion Assets represent a category of ad extensions that allow advertisers to highlight special offers directly within their search ads. When properly configured, these assets appear alongside standard ad copy, displaying information about sales, discounts, promotional periods, and applicable conditions.
How Promotion Assets Integrate with Search Campaigns
The placement of Promotion Assets within search ad layouts varies based on device type and ad format, but they consistently appear in positions that complement the primary ad copy. On desktop, they typically display below the description fields, adjacent to other extensions like sitelinks.
From a data perspective, Promotion Assets contribute to campaign performance metrics in several ways. They increase click-through rates by providing additional reasons to engage with ads, and when combined with appropriate conversion tracking, they can help advertisers understand which promotional offers drive the most valuable actions.
The Role of Promo Codes in Performance Advertising
Promo codes have long served as a bridge between digital advertising and measurable business outcomes. When a customer uses a promo code at checkout, that action creates an explicit connection between the advertising exposure and the resulting sale, enabling attribution that might otherwise be difficult to establish.
Traditional promo code formats in Google Ads required customers to manually enter alphanumeric codes during checkout, a process that introduced friction. Barcode and QR code formats reduce these friction points by providing scannable alternatives that integrate with mobile devices and point-of-sale systems.
Understanding the technical and business benefits of barcode and QR code options
Scannable Code Generation
Google automatically generates scannable barcode and QR code images based on your promotional details, eliminating the need for external design work.
Omnichannel Redemption
Enable customers to redeem offers in physical stores using the same promotional mechanics advertised in search campaigns.
Reduced Friction
Scannable codes eliminate the need for customers to manually remember and enter promo codes at checkout.
Cross-Channel Measurement
Track promotional performance across online and offline channels with consistent attribution mechanics.
The New Barcode and QR Code Formats
Google Ads' introduction of barcode and QR code formats for Promotion Assets represents a significant expansion of what these extensions can accomplish. Rather than requiring customers to manually enter text, advertisers can now present scannable codes that work with mobile cameras, barcode readers, and point-of-sale systems.
Technical Requirements and Display Considerations
Barcodes and QR codes displayed through Promotion Assets must meet certain technical specifications to ensure scannability and accurate offer redemption. Google generates these codes based on the promotional details provided.
QR codes offer greater data capacity than traditional barcodes, allowing advertisers to encode more complex promotional information or direct links to landing pages. The choice between barcode and QR code formats may depend on the point-of-sale systems and scanning infrastructure the advertiser's customers use.
Business Models Best Suited for Scannable Formats
Retailers with both online and physical stores can advertise promotions through Google Search while enabling in-store redemption through scannable codes. Restaurant and hospitality businesses benefit when running promotions through delivery platforms, takeout services, or in-person dining offers. Service businesses can use scannable codes to streamline appointment booking and first-visit discounts.
Implementation Best Practices
Successful implementation of barcode and QR code formats in Promotion Assets requires attention to several operational factors. Advertisers should establish clear processes for generating and updating scannable codes, coordinating with retail or point-of-sale teams to ensure proper redemption procedures, and monitoring performance to optimize offer presentation over time.
Configuring Promotion Assets in Google Ads
The workflow for creating Promotion Assets with barcode or QR code formats begins with accessing the Extensions section within Google Ads campaigns. Advertisers select the appropriate campaign and ad group level where assets should serve, then choose "Promotion" from the available extension types.
When selecting scannable formats, advertisers specify offer details including discount type, minimum purchase requirements if applicable, and promotional period dates. The system generates corresponding barcode or QR code images based on this information. For advertisers seeking personalized growth plans that align promotional strategies with business objectives, these new formats offer additional flexibility in campaign design.
Coordinating Across Marketing and Operations
Effective use of scannable Promotion Assets requires alignment between marketing teams creating ads and operational teams processing redemptions. Marketing should communicate promotional details, timing, and expected volume to retail or service staff before campaigns launch.
Discrepancies between what ads promise and what checkout systems apply create friction that undermines campaign effectiveness. Regular communication channels help resolve these issues quickly and prevent recurring problems through process improvements.
Measurement and Performance Optimization
Understanding how scannable Promotion Assets contribute to campaign performance requires examining multiple metrics across the customer journey. Click metrics indicate whether promotional offers attract attention and encourage engagement with ads.
Attribution Considerations for Omnichannel Campaigns
Attribution for campaigns using scannable Promotion Assets must account for the complexity of omnichannel customer journeys. Standard attribution models may not fully capture paths where customers discover offers through search advertising and later convert in-store using scannable codes.
Incrementality testing provides another avenue for understanding true promotional impact. By intermittently suppressing Promotion Assets for portions of ad traffic and comparing conversion rates, advertisers can estimate the incremental lift these extensions provide beyond baseline ad performance.
As Google's AI capabilities continue to reshape search marketing, advertisers should anticipate how automation and machine learning will enhance promotional asset optimization. These advances will enable more sophisticated testing and measurement approaches.
Optimizing Offer Presentation
Performance optimization extends beyond bid and budget management to include offer mechanics and presentation details. Testing different discount structures--percentage versus fixed amount, varying discount levels--helps identify combinations that drive the strongest response from target audiences.
Ad creative pairing affects how Promotion Assets perform within the broader ad context. When headlines and descriptions establish clear expectations about offers, customers arrive at the scannable code with appropriate expectations.
Common Use Cases and Examples
Retail Campaigns
Retail advertisers frequently employ scannable Promotion Assets to drive store traffic during promotional periods. A clothing retailer advertising a spring sale through Google Search can include scannable codes that customers present at checkout, enabling tracking of campaign-driven store visits while providing a convenient redemption mechanism.
Restaurant and Hospitality
Restaurant and food service businesses use QR codes in Promotion Assets to facilitate easy redemption of special offers. A quick-service restaurant chain promoting a new menu item can include scannable codes that apply discounts when scanned at the register or through mobile ordering systems.
Professional Services
Professional service providers, including healthcare practices and financial services firms, use scannable codes to streamline new client acquisition offers. A dental practice advertising a new patient special can include QR codes that new patients scan during check-in.
Seasonal and Event-Based Promotions
Seasonal campaigns represent a particularly strong use case for scannable Promotion Assets. Holiday shopping promotions benefit from the efficiency gains scannable codes provide during high-volume retail periods. Flash sales and limited-time offers leverage scannable codes to create urgency while maintaining redemption efficiency.
