How Much Does CTV Advertising Cost for Law Firms?

The first question most law firms ask about CTV: How much does it cost?

The honest answer is that it depends, but not in a vague, evasive way. CTV pricing follows predictable patterns based on a few key factors. Here’s what you’ll actually pay and why.

CTV CPM Ranges

CPM stands for cost per thousand impressions. It’s how CTV inventory is priced.

Programmatic CTV: $20-$40 CPM

This is the most common range for law firms buying CTV through demand-side platforms (DSPs) like The Trade Desk, Amazon DSP, or specialized platforms like MNTN. You’re accessing inventory across multiple streaming publishers through automated buying.

Premium/Direct: $40-$60+ CPM

When you buy directly from publishers like Hulu or through private marketplace (PMP) deals with premium networks, expect higher CPMs. You’re paying for guaranteed placement in specific, brand-safe content.

Long-tail/FAST: $15-$25 CPM

Free ad-supported streaming (FAST) services like Pluto TV and Tubi can offer lower CPMs. The tradeoff is less premium content environment, though completion rates remain high.

What Affects CTV Pricing

Four main factors determine what you’ll pay:

1. Inventory Quality

Premium publishers (Hulu, Peacock, major network apps) charge more than long-tail inventory. You’re paying for content quality, brand safety, and audience attention.

2. Geography

Major metros like New York and Los Angeles have higher CPMs due to demand. Mid-market DMAs are typically less expensive. For law firms, this often works in your favor. You’re buying local, not national.

3. Audience Targeting

The more precise your targeting, the higher the CPM. Broad demographic targeting costs less than behavioral segments or first-party data matches. This is a tradeoff worth making, paying more for the right households beats paying less for everyone.

4. Deal Type

• Open exchange: Lower CPMs, less control over placement
• Private marketplace (PMP): Mid-range CPMs, better inventory guarantees
• Direct/guaranteed: Highest CPMs, specific publisher relationships

Most law firms work in the PMP and open exchange tiers through programmatic buying.

Minimum Budget Requirements

CPMs only tell part of the story. You also need enough budget to achieve meaningful reach and frequency.

Self-serve platforms and DSPs: Competitive campaigns require $15,000-$30,000 per month to generate enough impressions in a single DMA. Below this threshold, you may not achieve the frequency needed for recall.

Managed services: CTV agencies typically have minimums of $15,000-$25,000+ monthly for managed CTV campaigns with proper attribution.

Publisher direct: Buying directly from Hulu or major networks often requires $75,000+ commitments, sometimes significantly more.

For competitive PI firms, $15,000-$25,000 per month is the baseline for meaningful CTV presence. Scale to $50K+ for market dominance.

CTV vs Broadcast TV Costs

The comparison isn’t straightforward because the buying models differ.

Broadcast TV CPMs: $10-$25

Broadcast looks cheaper on a CPM basis. But you’re buying broad demographics, Adults 25-54, for example, across the entire market. The waste is significant.

CTV CPMs: $20-$40

CTV costs more per thousand, but you’re targeting specific households. The waste is dramatically lower.

The Math That Matters

Consider this scenario:

Broadcast: $15 CPM, but only 20% of impressions reach potential clients = effective CPM of $75 per relevant impression

CTV: $35 CPM, but 60% of impressions reach potential clients = effective CPM of $58 per relevant impression

The higher CPM often delivers better cost efficiency because you’re not paying to reach households that will never need a lawyer.

CTV vs Digital Video Costs

CTV also compares favorably to other digital video formats.

Social video (Facebook, Instagram): Lower CPMs ($10-$20), but completion rates of 20-40% due to scrolling and skipping. You’re paying for impressions that may never be watched.

YouTube: Variable CPMs, but skippable formats mean many viewers bail after 5 seconds. The cheap impression often isn’t a real impression.

CTV: Higher CPMs ($20-$40), but 90%+ completion rates. When you pay for an impression, someone actually watched it.

For law firm advertising where the message needs to land, completion rates matter more than raw CPM.

What Law Firms Should Budget

Here’s a practical framework for CTV budgeting:

These are CTV-specific budgets. Most firms run CTV alongside other channels, search, social, possibly broadcast, with CTV representing one component of total marketing spend.

Hidden Costs to Consider

Beyond media spend, factor in:

Creative production: You need video commercials. If you don’t have them, budget for production. Expect $15,000-$40,000+ for professional spots that perform.

Platform/management fees: Agencies typically charge 20% on top of media spend. This is standard and should be factored into your budget.

Attribution tools: Some advanced attribution (call tracking, site analytics) may have additional costs. Basic measurement is usually included.

The Bottom Line on CTV Costs

CTV isn’t the cheapest way to reach people. It’s often the most efficient way to reach the right people.

For law firms evaluating CTV:

• Expect $20-$40 CPM for most programmatic buying
• Budget $15,000-$25,000/month minimum for competitive single-market campaigns
• Compare on effective cost per qualified impression, not raw CPM
• Factor in production and management costs

The firms getting strong results from CTV aren’t necessarily spending the most. They’re spending smart, on the right inventory, targeting the right households, with creative that converts.
