CPM (Cost Per Mille) for Legal

July 2025 - July 2026

Insights

Detailed observation of presented data

Introduction

Legal industry CPMs ran materially above the market this year, showing pronounced spikes in late 2025 and early 2026 and a clear mid-spring trough. This analysis is based on $3B worth of advertising data from our dataset, which provides strong directional benchmarks. This analysis explores ad performance trends for Legal in All countries compared to the global benchmark for Cost per thousand impressions (CPM).

The story in the data

Legal CPMs started at about $40.70 in July 2025 and finished at $45.48 in July 2026, averaging roughly $44.5 across the 13-month window. The series reached a high of $52.94 in February 2026 and a low of $35.26 in April 2026. By comparison the global baseline averaged about $20.6 CPM over the same months, with a much narrower spread between $16.47 and $24.26.

Across months the Legal line ran roughly double the baseline on average — about 116% higher overall — and monthly gaps ranged from about +49% (April 2026) to about +176% (July 2026). Absolute movement was notable: Legal CPMs moved an average of ~$4.2 month-to-month (≈9–10% relative to the Legal mean) and the series’ standard deviation was about $5.2 (≈12% of its mean), underscoring above-average volatility versus the global benchmark.

Several sharp month-to-month shifts stood out: an October 2025 lift to roughly $50.37 from a September $43.78, a peak in February 2026 at $52.94, and a pronounced decline into April 2026 where CPMs fell to about $35.26 before rebounding through June and July 2026.

Seasonal and monthly dynamics

Seasonally, Legal CPMs show a late-year and early-year concentration of strength. Q4 into early Q1 (October–February) contains the biggest upward momentum, with October, December and February among the higher months. The opposite rhythm appears in spring: April and May 2026 form a noticeable trough, with April marking the lowest point. After that low, CPMs staged a multi-month rebound into early summer.

The baseline follows a gentler seasonal arc: smaller October and November upticks and a dip into mid-year, but without the amplitude seen in Legal CPMs. In short, Legal displays sharper peaks and deeper troughs inside the same seasonal windows where the global baseline remains steadier.

Country vs. Global

Viewed against the global benchmark, Legal CPMs were consistently above average and more volatile. Where the global benchmark stayed mostly between $16.5 and $24.3, Legal spanned roughly $35.3 to $52.9 — a wider absolute range (~$17.7 vs ~$7.8). Relative gaps varied by month: the narrowest gap (April 2026) saw Legal about 49% higher than global; the widest gap (July 2026) saw Legal roughly 176% higher. Overall, Legal CPMs operated at roughly 2.2–2.8x the baseline in peak months and about 1.5–2.0x in quieter months.

Understanding the Data

Insights & analysis of Facebook advertising costs

Cost Per Mille (CPM) is the cost advertisers pay for 1,000 impressions of their Facebook ad. In the Legal industry, Facebook ad costs can be influenced by seasonal trends and market competition. Geographic targeting affects ad costs based on market competition and user engagement in different regions. Different campaign objectives lead to varying costs based on how Facebook optimizes for your specific goals. The data shown represents median values across multiple campaigns, and individual results may vary based on ad quality, audience targeting, and campaign optimization.

Why we use median instead of average

We use the median CTR because the underlying distribution of click-through rates is highly skewed, with a small share of campaigns achieving extremely high CTRs. These outliers can inflate a simple average, making it less representative of what most advertisers actually experience. By using the median—which sits at the midpoint of all campaigns—we provide a more rigorous and realistic benchmark that reflects the true underlying data model and helps you set attainable performance expectations.

Key Factors Affecting Facebook Ad Costs

  • Competition within your selected industry and audience demographics
  • Ad quality and relevance score – higher quality ads can lower costs
  • Campaign objective and bid strategy
  • Timing and seasonality – costs often increase during holiday periods
  • Ad placement (News Feed, Instagram, Audience Network, etc.)

Note: This data represents industry median values and benchmarks. Your actual costs may vary based on specific targeting, ad creative quality, and campaign optimization.

What affects CPM rates on Facebook Ads?

CPMs are heavily influenced by competition, seasonality (e.g., Q4 costs more), audience size, and ad quality. Smaller audiences and lower relevance scores often lead to higher CPMs.

Why does my CPM vary so much between campaigns?

Different campaign objectives, bidding strategies, and even time of day can change your CPM. For example, conversion campaigns usually have higher CPMs than traffic ones. Also, broad targeting tends to drive lower CPMs.

What's a competitive CPM for 2025?

In most industries, CPMs range from $5 to $18 depending on the region and objective. Retail and e-comm campaigns often sit at the higher end. Our live data above shows a breakdown by country and industry.

Does audience size or targeting affect CPM more?

Both matter, but audience quality (intent + match with your offer) usually has more impact than pure size. However, extremely tight audiences often lead to expensive CPMs due to limited delivery opportunities.

Should I worry more about CPM or CPC?

Depends on your goal. For awareness, CPM is more relevant. For performance campaigns, CPC and CPA matter more. But all are connected—inefficient CPMs can inflate your entire funnel.
