What Is CTV and Why It Matters for Automotive Marketing
Connected TV (CTV) refers to any television set that connects to the internet and can stream digital video content, whether through built-in smart TV functionalities or external devices like streaming sticks, consoles, or set-top boxes. This technology has fundamentally transformed how audiences consume video content, with U.S. adults spending an average of 2 hours and 15 minutes per day watching content on connected TVs in 2024.
For automotive marketers, CTV represents a critical opportunity to reach car buyers where they actually spend their time. The automotive purchase journey increasingly begins with digital research, but television remains highly influential throughout the decision-making process. According to Video Advertising Bureau research, 40% of millennials cite TV as their primary motivator for taking a test drive, making CTV an essential channel for dealerships targeting this demographic.
CTV vs Traditional Broadcast Television
Traditional broadcast television operates on a broad demographic targeting model, delivering ads to entire time slots or programs regardless of individual viewer relevance. CTV advertising, by contrast, leverages programmatic technology to deliver ads to specific households based on detailed audience characteristics, behaviors, and interests.
Key differences include:
- Targeting precision: CTV enables household-level targeting versus broad age/gender demographics
- Measurement capabilities: CTV provides detailed performance metrics versus estimated ratings
- Audience reach: CTV effectively reaches cord-cutters and cord-nevers who don’t subscribe to traditional cable
Why Auto Shoppers Stream More Than They Watch Cable
The shift toward streaming content is particularly pronounced among key automotive demographics. The number of millennial CTV viewers is anticipated to rise from 56.8 million in 2023 to 62.6 million by 2025. These demographics are actively researching vehicles online but remain highly receptive to television advertising—making CTV the perfect bridge between digital research and traditional TV influence.
How CTV Advertising Works in Programmatic Ecosystems
CTV advertising operates within a sophisticated programmatic ecosystem that automates the buying and selling of ad inventory through real-time auctions. This system connects advertisers with available ad space across thousands of streaming apps and platforms, enabling precise targeting and optimization at scale.
The programmatic CTV ecosystem consists of several key components:
- Demand-Side Platforms (DSPs): Technology platforms that allow advertisers to purchase ad inventory across multiple supply sources
- Supply-Side Platforms (SSPs): Technology used by publishers to sell their ad inventory to multiple buyers
- Ad Exchanges: Digital marketplaces where inventory is bought and sold in real-time
- Data Management Platforms (DMPs): Systems that collect and organize audience data for targeting purposes
Programmatic CTV Buying Mechanics
When an advertiser wants to run a CTV campaign, they upload their targeting criteria and creative assets to a DSP like The Trade Desk. As users stream content on CTV apps, the available ad inventory is offered through SSPs to ad exchanges, where DSPs automatically bid on impressions that match the advertiser’s targeting criteria.
This real-time bidding process happens in milliseconds and considers factors like:
- Audience characteristics and behaviors
- Geographic location
- Time of day
- Content context
- Historical performance data
The winning bid’s ad is then served to the viewer, with performance metrics tracked and reported back to the advertiser for optimization.
DSPs That Power Connected TV Campaigns
The Trade Desk has emerged as the leading DSP for CTV advertising, offering comprehensive access to premium streaming inventory across major platforms. Other notable DSPs include Amazon DSP, Google Display & Video 360, and specialized CTV platforms like MNTN and MadHive.
For automotive groups, The Trade Desk provides the most robust capabilities for activating first-party data and building look-alike audiences at scale across the CTV ecosystem.
What Look-Alike Audiences Are and How They Drive Scale
Look-alike audiences represent one of the most powerful targeting capabilities in digital advertising. In essence, a look-alike audience uses advanced algorithms and machine learning to analyze the data of your current customers—their demographics, interests, and behaviors—and creates an audience that mirrors them.
The process begins with a “seed audience,” which serves as the foundation for the look-alike model. The algorithm identifies common characteristics and patterns within this seed audience, then scans the broader population to find users who share similar attributes. The resulting look-alike audience typically expands your reach by 1-10% of the total addressable population, depending on your similarity threshold.
Seed List Requirements for Effective Modeling
The quality of your seed audience directly determines the effectiveness of your look-alike model. As marketing professionals consistently emphasize, “an algorithm is only ever as good as the data it is fed.”
For automotive applications, effective seed audiences typically include:
- Current customers with verified contact information
- Recent vehicle purchasers (within 12-24 months)
- High-value service customers
- Lease-end customers approaching renewal dates
- Website visitors who viewed multiple vehicle detail pages
Balancing Reach and Relevance in Look-Alike Expansion
Most advertising platforms allow you to adjust the similarity threshold of your look-alike audience, typically ranging from 1% (most similar) to 10% (broadest reach). For automotive marketing, a 1-3% similarity threshold often provides the optimal balance between reach and relevance, as vehicle purchases involve significant consideration and high customer value.
A 1% match will be closely aligned to your first-party audience, where a 10% match will be less accurate, but will increase your potential reach exponentially. Your choice here will largely depend on how specific your product or offering is, how long your campaign is running, your overall budget, and your goals.
Building Look-Alike Audiences From Automotive First-Party Data
Automotive groups possess a wealth of first-party data that serves as ideal seed material for building highly effective look-alike audiences. Unlike generic demographic targeting, leveraging your own customer data ensures your look-alike models reflect the actual characteristics of your best buyers.
Which Dealer Data Sources Make the Strongest Seeds
The most effective seed audiences for automotive look-alike modeling include:
- CRM lists: Customer relationship management systems contain purchase history, contact information, and communication preferences
- DMS transaction history: Dealer management systems provide detailed records of vehicle purchases, service visits, and financing arrangements
- Service appointment records: Customers who regularly service their vehicles demonstrate loyalty and higher lifetime value
- Lease-end dates: Customers approaching lease expiration represent prime prospects for new vehicle purchases
- VIN ownership data: Vehicle identification number records enable targeting of specific make/model owners for conquesting campaigns
First-party data typically delivers the highest ROI for CTV advertising due to its accuracy and relevance, making these internal data sources invaluable for building look-alike audiences.
Privacy Compliance When Uploading Customer Lists
When activating first-party data for CTV campaigns, automotive groups must ensure proper privacy compliance. This includes:
- Hashing customer emails: Converting email addresses to secure hash values (SHA-256) before uploading
- Obtaining proper consent: Ensuring customers have opted in to marketing communications
- Implementing privacy controls: Using hashed first-party identifiers with privacy controls aligned to industry standards
- Complying with regulations: Adhering to CCPA, GDPR, and other relevant privacy laws
Demand Local’s LinkOne Data platform addresses these requirements through secure APIs and advanced encryption that keep your data safe at every stage, empowering your campaigns with both reliability and results.
Activating Look-Alike Audiences on CTV: Step-by-Step Workflow
Implementing CTV look-alike audience campaigns requires a systematic approach that ensures proper setup, optimization, and measurement. Here’s a step-by-step workflow for automotive groups:
Uploading First-Party Lists to The Trade Desk
- Prepare your seed audience: Export customer lists from your CRM or DMS, ensuring data quality and completeness
- Hash email addresses: Convert email addresses to SHA-256 hash values for privacy protection
- Create audience segment: Upload the hashed list to The Trade Desk as a first-party audience segment
- Build look-alike model: Use The Trade Desk’s look-alike creation tool to generate a new audience based on your seed
- Set similarity parameters: Choose your desired expansion percentage
Setting Frequency Caps to Avoid Ad Fatigue
CTV’s full-screen, high-attention environment makes it particularly susceptible to ad fatigue if viewers see the same message too frequently. Best practices include:
- Limiting impressions: Cap frequency at 3-5 impressions per household per week
- Rotating creative: Develop multiple ad variations to maintain message freshness
- Dayparting strategically: Focus delivery during high-engagement viewing periods
- Excluding recent converters: Remove customers who have recently purchased from active campaigns
Creative Best Practices for 15- and 30-Second Spots
CTV creative should be optimized specifically for the streaming environment:
- Lead with your strongest message: Capture attention within the first 3 seconds
- Include clear branding: Ensure logo visibility throughout the ad
- Feature specific vehicles: Highlight inventory that aligns with your look-alike audience characteristics
- Add strong calls-to-action: Direct viewers to specific landing pages or vehicle detail pages
- Optimize for sound-on viewing: Design audio and visual elements to work together effectively
Connected TV YouTube and Other Premium Inventory Sources
While CTV encompasses a wide range of streaming platforms and apps, certain inventory sources offer particular advantages for automotive advertisers. YouTube on smart TVs has emerged as a premium placement that combines the targeting capabilities of digital video with the full-screen impact of television.
Why YouTube CTV Inventory Delivers Higher Completion Rates
YouTube’s CTV inventory includes content viewed on smart TVs through the YouTube app, as well as YouTube TV’s live streaming service. This inventory offers several advantages:
- High completion rates: YouTube CTV ads benefit from the platform’s skippable ad model, where advertisers only pay for completed views
- Cost efficiency: CTV advertising typically operates on CPMs of $20-$40, with actual costs varying by market, targeting, inventory quality, and deal type
- Cross-device continuity: YouTube’s logged-in user base enables consistent messaging across mobile, desktop, and CTV
Choosing Between Ad-Supported Streaming and YouTube Placements
Other premium CTV inventory sources include ad-supported streaming services like Hulu, Pluto TV, and Tubi. Each offers distinct advantages:
- Hulu: Premium content with engaged audiences, particularly strong for reaching younger demographics
- Pluto TV: Free ad-supported television with diverse channel options and broad reach
- Tubi: Movie and TV show library with strong completion rates and cost-effective pricing
For automotive groups, a diversified CTV strategy that includes both YouTube and premium streaming services typically delivers the best results, balancing reach, relevance, and cost efficiency. Note that YouTube on CTV and YouTube TV are only accessible via Google Ads or DV360, not through third-party DSPs like The Trade Desk.
Measuring CTV Performance: Metrics That Matter for Auto Groups
Unlike traditional television’s estimated ratings and inferred impact, CTV advertising provides detailed, measurable performance data that directly ties to automotive business outcomes. Effective measurement goes beyond basic video metrics to capture the full customer journey from ad exposure to vehicle purchase.
Tracking VDP Visits as a Proxy for Lower-Funnel Intent
Vehicle Detail Page (VDP) visits represent a critical mid-funnel KPI for automotive CTV campaigns. When CTV viewers visit specific vehicle pages on your dealership website, it indicates genuine purchase intent and engagement with your messaging.
Key metrics to track include:
- VDP visit rate: Percentage of CTV viewers who visit VDPs
- VDP depth: Number of VDPs viewed per session
- VDP duration: Time spent viewing vehicle details
- VDP-to-lead conversion: Percentage of VDP visitors who submit leads
Using Sales Match-Back to Prove CTV ROI
The ultimate measure of CTV effectiveness is its contribution to actual vehicle sales. Sales match-back analysis connects CTV ad exposure to eventual purchases by matching customer contact information from sales records with CTV audience data.
This attribution approach provides:
- Direct ROI measurement: Actual revenue generated from CTV campaigns
- Customer lifetime value: Long-term value of CTV-acquired customers
- Model-specific performance: Which vehicles perform best with CTV audiences
- Geographic effectiveness: Regional variations in CTV campaign performance
Case Study: Moving 12 Aged EV Units With CTV + Look-Alike Targeting
One of the most compelling demonstrations of CTV’s effectiveness for automotive groups comes from a real-world Demand Local client result involving aged electric vehicle inventory. A dealership struggling to move 12 aging EV units implemented a targeted CTV campaign using look-alike audience modeling.
The strategy involved:
- Seed audience creation: Using CRM data from recent EV buyers as the foundation
- Look-alike expansion: Building a 2% look-alike audience targeting eco-conscious households
- Dynamic creative integration: Automatically featuring the specific aged EV units in CTV ads
- Cross-channel reinforcement: Combining CTV with dynamic display advertising
The results were remarkable: all 12 aged EV units sold within weeks, significantly reducing inventory carrying costs and freeing up capital for new inventory. This case study demonstrates how CTV’s combination of precise targeting, high engagement, and measurable results can solve specific automotive business challenges.
Combining CTV With Other Channels: Omnichannel Sequencing Tactics
While CTV excels at building brand awareness and reaching high-value audiences, its true power emerges when integrated into a coordinated omnichannel strategy. Automotive groups can amplify CTV’s impact by sequencing messages across multiple touchpoints throughout the customer journey.
Using CTV to Warm Audiences Before Paid Search
A highly effective sequencing tactic involves using CTV to build initial awareness, then retargeting those exposed audiences with paid search campaigns. This approach leverages CTV’s broad reach and high attention to create top-of-mind awareness, then captures intent when viewers search for specific vehicles or dealerships.
Key implementation steps:
- Track CTV exposures: Use pixel-based tracking to identify households exposed to CTV ads
- Create search audiences: Build remarketing lists based on CTV exposure data
- Optimize search bids: Increase bids for CTV-exposed audiences to capture heightened intent
- Align messaging: Ensure consistent creative themes across CTV and search campaigns
Layering DOOH Near Dealerships After CTV Exposure
Digital Out-of-Home (DOOH) advertising provides another powerful reinforcement channel for CTV campaigns. By placing programmatic DOOH ads near dealership locations, automotive groups can remind CTV-exposed audiences of their brand as they travel through relevant geographic areas.
Demand Local’s programmatic DOOH solution enables geo-fenced, data-driven outdoor advertising that extends CTV reach into physical environments where auto shoppers travel, reinforcing brand recall before lot visits.
Common Pitfalls When Launching CTV Campaigns for Dealerships
Despite CTV’s advantages, automotive groups often encounter common challenges when implementing their first campaigns. Understanding these pitfalls can help ensure successful CTV adoption and optimization.
Why a 500-Record Seed List Rarely Scales
One of the most frequent mistakes involves using seed audiences that are too small to generate effective look-alike models. While some platforms accept seed lists as small as 100 records, effective automotive look-alike audiences typically require 1,000+ high-quality customer records to identify meaningful patterns and achieve sufficient scale.
For smaller dealerships with limited customer databases, consider:
- Combining multiple data sources: Merge CRM, service, and website visitor data
- Expanding geographic scope: Include customers from neighboring markets
- Partnering with auto groups: Pool data across multiple rooftops for enhanced scale
The Hidden Cost of Generic Creative in Auto CTV
Another common pitfall involves using generic, brand-focused creative instead of vehicle-specific messaging. CTV’s targeting precision demands equally precise creative that speaks directly to the audience’s interests and needs.
Effective automotive CTV creative should:
- Feature specific vehicles: Highlight models relevant to your look-alike audience
- Include pricing and offers: Provide concrete reasons to visit or inquire
- Showcase unique selling points: Emphasize features that differentiate your inventory
- Incorporate local elements: Reference your specific market or community
Emerging Trends: AI-Driven Optimization and Inventory-Level CTV Creative
The CTV advertising landscape continues to evolve rapidly, with new technologies and capabilities emerging that further enhance automotive marketing effectiveness. Two particularly promising trends include AI-driven optimization and inventory-level creative personalization.
How VIN-Level CTV Ads Work at Scale
Advanced platforms now enable VIN-level personalization in CTV advertising, automatically featuring specific vehicles from your inventory in video ads. This capability combines real-time inventory feeds with dynamic creative optimization to ensure CTV ads always showcase available vehicles with accurate pricing and specifications.
Demand Local’s Inventory Marketing solution syncs inventory nightly and automatically pulls the right VIN, price, and imagery into live ads, ensuring accuracy and reducing wasted impressions.
AI Bidding Strategies That Lower CPMs
Artificial intelligence is also transforming CTV bidding strategies, enabling more efficient ad spend allocation and lower effective CPMs. AI-driven platforms analyze historical performance data, audience characteristics, and market conditions to optimize bids in real-time, ensuring maximum impact for every advertising dollar.
Demand Local’s AI-driven performance tracking enhances optimizations for continuity in tactics, ad messaging, and post-click consumer experience, enabling real-time creative and bid adjustments.
