Facebook Ads Cost Per Purchase Benchmarks for Public Administration

Introduction

Global cost per purchase for Public Administration followed a clear arc over the past 12 months: a sharp rise into late winter, a gradual cool-down through mid‑year, a brief late‑summer lift, and a pronounced retreat by October. The year’s high came early; the low points clustered at the bookends. Volatility was moderate, with a handful of standout swings that defined the rhythm. 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 Public Administration across all countries compared to the global benchmark.

The story in the data

The series opens at $42.70 in November, surges to a peak of $53.80 in February (+26% from November), and closes at $43.29 in October—nearly flat versus the starting point (+1%). Across the period, cost per purchase averaged about $49.28, with a range of $11.10 from the $42.70 low (November) to the $53.80 high (February). Seven of the twelve months sat above the average (December through May plus August), while five months undershot it (June, July, September, October, November).

Month‑to‑month volatility averaged roughly $2.53, about a 5% swing relative to the mean. The most dramatic jump occurred from November to December (+$7.41), setting up the winter peak. The steepest single‑month pullback landed in October (−$5.38 vs. September), marking the year’s second‑lowest point after November. From the February high, costs eased into mid‑year (−12% by July), then briefly rebounded in August (+$3.09, +7% month‑over‑month) before giving way to a steady decline through early Q4.

Seasonal and monthly dynamics

Seasonality is unmistakable. Q1 carried the highest acquisition costs, averaging roughly $52.77 (January–March), consistent with push‑heavy winter demand that often elevates Facebook Ads benchmarks for purchase‑based outcomes. Q2 moderated to about $50.29 as the market cooled, and Q3 softened further to around $48.71, even with an August pop. Early Q4 reversed the late‑summer lift: October fell to $43.29, down 14% from August and 19% below February’s peak.

This cadence—winter strength, mid‑year easing, late‑summer bounce, and October reset—frames the year’s momentum more than any single spike or dip. Even with CPM analysis and CPC trends fluctuating beneath the surface, the endpoint suggests a return toward the lower band of the range.

Country vs. Global

With the country set to all available markets, this Public Administration view represents the global curve for cost per purchase. The benchmark itself rose into February (+26% from November), then slid 20% by October, ending near its initial level. Range pressure was moderate (about 23% of the mean), and monthly variability clustered around $2.50 either direction. In other words, at the all‑country aggregate, Public Administration’s CPP defines the global reference rather than deviating from it.
