Google has announced a series of ad-tech compliance reforms after being fined €3 billion by the European Union for self-preferencing practices. The reforms include allowing publishers to set their own ad prices, improving interoperability, and expanding available tools, all aimed at enhancing competition in the digital advertising sector. This move comes as the global digital ad market is projected to reach $757.5 billion by 2025, with Google anticipated to generate $205 billion in revenue.
