This paper examines the global prevalence and strategies of political microtargeting on Facebook and Instagram across 95 countries during 113 national elections. Using the Meta Ad Targeting dataset, the study analyzes the targeting and exclusion strategies of 54,000 political advertisers who ran 2.5 million ads between August 2020 and December 2022. The findings indicate that political campaigns worldwide use targeted advertising, with most spending allocated to a single targeting criterion. However, in wealthier countries and electoral systems with proportional representation, more money is spent on microtargeting by combining multiple criteria. Targeting strategies vary along ideological lines, with parties using microtargeting regardless of their political ideology. The study introduces a semi-automatic method to identify worldwide political advertisers and highlights the need for more research beyond the global north. The results have important implications for policymakers and stakeholders seeking to regulate political microtargeting techniques.This paper examines the global prevalence and strategies of political microtargeting on Facebook and Instagram across 95 countries during 113 national elections.
