Facebook Ads Cost Per App Install Benchmarks for Legal

Introduction

Headline: Cost-per-app-install for Legal shows a choppy year with a dramatic February spike and a net decline from June to June.

“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.”

Note: the selected industry/country series for Legal in All countries was not provided separately, so the narrative below focuses on the available global COST_PER_APP_INSTALL benchmark series and what it reveals about industry ad performance over the last 13 months.

The story in the data

The global median COST_PER_APP_INSTALL began at about $18.36 in June 2025 and ended at $11.85 in June 2026 — a decline of roughly 35.5% over the period. Across the 13-month window the mean monthly cost was approximately $15.55. The lowest monthly median was $9.34 in December 2025; the highest was an outlier $30.13 in February 2026. The full range spanned about $20.79, which is roughly 134% of the average monthly level.

Monthly moves were volatile: the average absolute month-to-month change was around $5.55, meaning typical monthly swings represented roughly a third of the average cost. The biggest single jump was January → February (+135%), followed by February → March, when costs fell by roughly 45%. Other notable shifts include the large drop from June → July (about −46%) and the December trough (about −37% from November).

Keywords that surface alongside this trend include Facebook Ads benchmarks, CPC trends, CPM analysis and CTR performance — all part of the broader conversation around country-specific ad costs and industry ad performance even when the metric in view is cost per install.

Seasonal and monthly dynamics

Seasonality shows a softer finish to the calendar year: costs eased into December, producing the period’s low. Early Q1 showed a rebound into January and then an extreme spike in February. After the February peak, March through June moved back toward mid-range levels but with intermittent rebounds (April’s rise) and pullbacks (May → June decline). That rhythm — softer late in the year, a Q1 rebound punctuated by a one-off spike, then a cooling into late spring — creates a lumpy seasonal profile rather than a smooth cycle.

Country vs. Global

Because a separate Legal-in-All-countries series was not supplied, direct country-vs-global gaps can’t be computed for this brief. The baseline series itself illustrates how variable global COST_PER_APP_INSTALL can be: at its narrowest, costs clustered near the mean; at their widest, February sat almost double the typical month. For discussions of country-specific ad costs and industry ad performance, the global benchmark here acts as the reference — showing periods that are above market (February) and below average (December) across the aggregated footprint.

Closing

Understanding cost-per-app-install trends for the Legal industry across All countries provides a clear, data-grounded picture of volatility and seasonality within Facebook Ads benchmarks and broader cost metrics. Cost-per-app-install benchmarks for Legal in All countries offer a baseline for industry ad performance and comparisons to global CPM analysis and CPC trends.
