CTV Costs for Law Firms: CPMs, Budgets, and ROI Chapter 3

CTV Budget by Market Size and DMA

Small DMA: $15-25K/month. Mid: $30-50K. Major: $50-80K. Top 25: $100K+. The budget that dominates a small market barely registers in NYC.

“How much should we spend on CTV?” depends primarily on one factor: market size. The same $50K monthly budget that dominates Lincoln, Nebraska barely registers in Chicago. For a breakdown of the pricing mechanics, the CTV CPM guide explains what drives costs up or down.

A $50K monthly investment in Spokane buys dominance. That same $50K in Los Angeles buys invisibility. Market size isn’t a detail. It’s the entire budget conversation.

Why Market Size Changes Everything

The math is straightforward. Bigger markets have more households. More households require more impressions. More impressions cost more money. And bigger markets attract more competitors bidding up the same inventory.

The gap isn’t linear. It’s exponential. A top-10 DMA doesn’t cost twice as much as a small market. It costs five to eight times as much to achieve the same frequency and recall.

Small Market Budgets (DMA Rank 100+)

Population under 500K. Think Amarillo, Fargo, Springfield MO, Spokane. These markets are CTV’s sweet spot for firms looking to build a household name without seven-figure budgets.

The advantage of small markets is concentration. Fewer households means your budget builds frequency fast. Three to five weekly exposures are achievable at $20K/month. That’s enough for recall. That’s enough for someone to remember your name after a car accident.

Competition is lighter too. In Spokane, total monthly legal ad spend is around $1M. In those markets, $25K/month doesn’t just give you presence. It gives you dominance. At working budget, expect 350K-600K monthly impressions with meaningful frequency against your target audience.

Mid-Size Market Budgets (DMA Rank 50-100)

Population 500K-1.5M. Louisville, Oklahoma City, Memphis, Richmond. These markets are the proving ground. Big enough that budget matters but small enough that smart allocation creates real separation.

This is where the minimum threshold really bites. Entry-level budgets ($20K) dilute across too many households. You end up with one or two exposures per week. Not enough for recall. Not enough for action. The viewer saw your ad once three weeks ago. They don’t remember you.

Working budgets ($30-50K) build three to four weekly exposures. That’s the recognition threshold. That’s when people start searching your name after they see the spot. For context: Richmond has about $1.5M in monthly legal ad spend with Morgan holding 16.7% share. A $40K monthly investment puts you in the conversation.

Major Market Budgets (DMA Rank 25-50)

Population 1.5-3M. San Diego, Denver, Charlotte, St. Louis, Portland. Competition intensifies. Multiple PI firms are already spending aggressively on both broadcast and streaming.

Charlotte has $2.4M in monthly legal ad spend with no firm above 11% share. That’s a fragmented market where a disciplined CTV buyer at $60K/month can build meaningful share. Denver sits at $3.1M with 22% going to streaming. St. Louis is $3.3M with Morgan leading.

In these markets, creative quality becomes the multiplier. Everyone can buy impressions. Not everyone has a spot worth watching. A $60K media budget with a $25K creative investment outperforms $85K in media with forgettable creative. Every time.

Top Market Budgets (DMA Rank 1-25)

Population 3M+. Chicago, Dallas, Houston, Philadelphia, Atlanta, LA, New York. These are the markets where Morgan and Morgan spends millions monthly and the entry price just to be noticed is steep.

New York: $14.5M monthly in legal advertising. Only 11% goes to streaming. Dallas: $6.9M with Thomas J. Henry controlling 35% share. Houston: $7.2M with Jim Adler dominating broadcast. Atlanta: $12.9M and 48% streaming adoption, the highest we track.

These numbers aren’t abstract. They’re the competitive landscape you’re stepping into. At $75K/month in Dallas, you’re outspending most firms on CTV. But Thomas J. Henry spends more in a week than most firms spend in a quarter. The play isn’t to outspend him. It’s to out-target him. CTV’s precision is the advantage over broadcast’s blunt reach.

Below the Floor

Every market has a floor. Below it, CTV isn’t a bad investment. It’s not an investment at all. It’s noise.

Below Minimum

  • One to two weekly exposures per household
  • No recall. No recognition. No action.
  • Attribution data is statistical noise
  • Can't optimize what you can't measure
  • Money spent without results to show for it

At Working Budget

  • Three to five weekly exposures
  • Recognition builds. Names stick.
  • Measurable lift in branded search
  • Enough data to optimize targeting and creative
  • ROAS improves 24% after 90 days of consistent spend

If you can’t hit the minimum for your market, don’t do CTV yet. That’s not a failure. It’s discipline. Put the money into search and SEO until your budget supports a real CTV program.

Most firms see better ROI from Option 1. Dominance in one market beats presence in several. Data from where $150 million in legal advertising goes shows how top spenders concentrate their budgets geographically.

Creative production sits outside this monthly allocation. Budget it annually: $15-35K for initial production, $5-15K for annual refreshes. A separate line item that multiplies everything above it.

Multi-Market Strategy

Firms in multiple DMAs face a hard choice: concentrate or distribute?

Concentrate First

  • Full working budget in your primary market
  • Build dominance before expanding
  • Best ROI per dollar for most firms
  • Prove the model, then replicate
  • One strong market beats three weak ones

Parallel Launch

  • Presence across markets simultaneously
  • Faster geographic coverage
  • Lower impact per individual market
  • Harder to optimize and attribute
  • Works when budget supports minimums everywhere

The math almost always favors concentration. Build dominance in your primary DMA. Prove the ROI framework. Then replicate in market two. The firms that try to be everywhere at once end up being noticed nowhere.

Exception: if your budget genuinely supports working-level investment in multiple markets simultaneously, parallel makes sense. A firm spending $200K/month can comfortably run $75K in two major markets and $50K in a third. That works. A firm spending $75K trying to cover three markets at $25K each in major DMAs? That’s below threshold in all three.

Scaling Up

Once CTV is working, scaling follows a curve, not a line. Your first $50K has maximum per-dollar impact. From $50K to $100K, you’re extending reach efficiently. Past $100K, you’re still growing household coverage but incremental efficiency declines. That’s not a problem. Absolute lead volume keeps climbing. And that’s what signs cases.

ROAS improves 24% after 90 days of consistent investment. CPA drops 64% over the same period. The compounding effect is real. Don’t cut a working campaign because month one looked expensive. Month three tells the truth.
