Is CTV Better Than Facebook Ads for ROI?

CTV can deliver better blended or long-term ROI when the goal is incremental reach, demand creation, high-value customer acquisition or market expansion. CTV should not be judged only by last-click conversions because its effect often happens before someone searches, visits a website or completes a purchase.

Measurement is part of the problem. Nielsen's 2024 marketing research found that only 31% of global marketers were very confident in measuring CTV ROI.

CTV vs Facebook Ads for ROI: At a Glance

Why Facebook Ads Usually Win for Immediate ROI

Facebook ads, usually managed through Meta Ads Manager, are often the stronger first choice when a campaign needs measurable actions quickly.

Meta's advertising system uses conversion signals such as purchases, signups, app events and catalog sales. It also reports and optimizes campaigns based on the actions advertisers send back to the platform.

Those reported conversions are useful, but they are not automatically the same as incremental conversions. Even so, Facebook ads have several practical advantages:

1. Faster optimization

Campaigns can identify which audiences, creative assets and placements are producing the selected conversion event.

1. More direct response options

People can click, submit a form, view a product catalog, install an app or complete a purchase in a digital environment where those actions are easier to track.

1. Lower testing friction

Advertisers can test different messages, audiences and formats without committing to a full television-style production process.

1. Quicker reporting

Meta can report clicks, landing-page views, leads, purchases and other conversion events. These figures are not proof of incremental sales, but they are usually easier to access and act on than CTV conversion data.

For ecommerce, lead generation, subscription products and remarketing, these advantages often make Facebook ads the better starting point.

When CTV Can Deliver Better ROI

CTV can outperform Facebook ads when the business needs to create new demand rather than capture demand that already exists.

CTV is more likely to make sense when:

• The product has a high average order value or customer lifetime value.
• The target audience is broad enough to support efficient reach.
• The business already has reliable conversion tracking.
• The brand needs stronger awareness or consideration.
• Customers take weeks or months to make a purchase.
• Facebook audiences are becoming saturated.
• The campaign needs to reach households or viewers who are not efficiently reachable through social media.
• The creative benefits from sound, storytelling and a large-screen viewing environment.

CTV can affect a purchase before the buyer shows obvious intent. Google's Brand Lift and Search Lift tools are designed to measure changes in brand perception and search behavior instead of relying only on clicks or immediate conversions.

For example, someone might see a CTV ad, remember the brand, search for it later and purchase through organic search or direct traffic. A last-click report may assign the sale to another channel even if CTV helped create the demand.

The Measurement Problem

CTV and Facebook ads report different types of ROI.

Facebook ads operate close to the conversion event and can claim credit for actions within an attribution window. CTV exposure and conversion may happen on different devices. Someone might watch an ad on a television, search on a phone and buy on a laptop.

That journey is harder to connect deterministically. The Interactive Advertising Bureau describes this as an outcome and measurement gap between CTV and more established outcome-driven channels such as search and social. Server-to-server conversion APIs can improve CTV measurement, but the market remains more fragmented than social advertising.

Nielsen also identifies reach, campaign IDs and the commingled nature of CTV inventory as measurement challenges.

This does not mean CTV produces poor returns. It means the reported result depends heavily on how the campaign is measured.

Do Not Compare Meta-Reported ROAS With CTV Last-Click ROAS

A fair comparison uses the same business outcome and the same accounting rules.

ROAS

ROAS = Revenue attributed to advertising ÷ Advertising spend

ROI

ROI = Incremental profit - Total campaign cost ÷ Total campaign cost

Total campaign cost can include:

• Media spend
• Creative production
• Agency or platform fees
• Data and measurement costs
• Landing-page or offer development
• Discounts and fulfillment costs where relevant

For a CTV campaign, incremental profit is more useful than platform-attributed revenue. A campaign that generates fewer directly attributed conversions may still be profitable if it creates additional branded search, direct traffic, retail sales or assisted conversions.

How Should You Test CTV Against Facebook Ads?

Use an incrementality test instead of relying only on each platform's reporting.

1. Set One Primary Business Outcome

Choose one main metric, such as:

• Incremental purchases
• Qualified leads
• New customers
• Contribution margin
• Customer lifetime value
• Branded search volume
• Revenue per exposed household

Do not compare Facebook purchases with CTV video completions. They measure different stages of the customer journey.

2. Control the Budget and Audience

Run the campaigns over comparable periods and target similar geographic or demographic markets. Keep pricing, promotions, landing pages and sales capacity consistent.

3. Use a Holdout or Matched-Market Design

Possible approaches include:

• Geographic test and control regions
• Randomized conversion lift studies
• Household-level exposure analysis
• Pre- and post-campaign branded search analysis
• Media mix modeling for larger advertisers

Google's lift measurement framework compares exposed and control groups to estimate whether advertising caused changes in awareness, consideration or other outcomes. Google also warns that small measured lifts require large sample sizes to establish confidence.

4. Measure Beyond the First Seven Days

Facebook often produces faster visible results. CTV may influence purchases over a longer period, so evaluate the full sales cycle. This matters particularly for expensive products, financial services, healthcare, education and B2B offers.

5. Keep Creative Quality Comparable

A weak television commercial will not prove that CTV is ineffective. A poor social ad will not prove that Facebook is inefficient.

Creative format can change performance substantially. Meta reports that, in its analysis of 15 Reels split tests, native 9:16 video with audio and safe-zone formatting produced a lower cost per result than image ads in that specific test group.

Which Channel Should You Choose?

Choose Facebook ads first for short-cycle, trackable demand. Choose CTV first for broader reach, demand creation and longer purchase journeys.

Choose Facebook Ads First If:

• You need purchases or leads within days or weeks.
• Your budget is limited.
• You have a narrow, identifiable audience.
• Your offer is easy to understand and act on.
• You can track conversions reliably.
• You need rapid creative and audience testing.
• You are still proving product-market fit.

Choose CTV First If:

• You need broad reach and stronger brand awareness.
• Your product requires education or explanation.
• Your purchase cycle is long.
• Your customer value is high.
• You already have proven conversion economics.
• You need incremental reach beyond social platforms.
• Your brand can support high-quality video creative and proper measurement.

Use Both When the Budget Supports a Full-Funnel Strategy

One approach is to use CTV to create awareness and demand, then use Facebook and Instagram ads to retarget engaged users, reinforce the message and capture conversions.

Evaluate the campaigns together rather than assigning every conversion to one channel. Nielsen research shows that cross-platform measurement can help advertisers deduplicate audiences, calculate incremental reach and understand what each channel adds to the campaign.

Final Verdict

Facebook ads are usually better for short-term, directly measurable ROI. CTV is better for building demand, reaching new households and improving long-term or blended ROI.

If you have not proven your offer or conversion funnel, start with Facebook ads. If Meta is already producing efficient conversions and growth is slowing, test CTV with a controlled geographic or audience holdout.

The decision should come down to incremental profit per dollar, not just the ROAS reported by Facebook or the conversions attributed to a CTV platform.
