The digital marketing world in the United States is growing faster than ever, almost like a giant machine gaining more power each year. Recent research shows that the global digital marketing market reached $410.7 billion in 2024, and experts believe it will continue to grow at a strong 11.22%, possibly reaching $1.18 trillion by 2033.
Not only this, but the US digital marketing software market alone is expected to grow at 17.8% from 2023 to 2030. In this vast world, search advertising remains the largest segment, accounting for nearly $202.4 billion.
