This guide breaks down the best platforms for CTV and OTT advertising in 2025 based on real experience, transparent tech, AI personalization strength, predictive segmentation models, and their ability to support automated customer targeting with high precision.
⭐ Why CTV and OTT Advertising Dominates in 2025
The reason CTV and OTT advertising is exploding is simple: consumers shifted their attention to streaming, and the ad tech caught up fast. With micro-segmentation, identity-based targeting, and richer analytics, brands can now reach audiences with accuracy that traditional TV could never match.
In my own campaigns, I’ve seen streaming outperform display by up to 4× when the creative, platform, and bidding model aligned properly.

Great for brands scaling internationally
If you’re trying to bring AI personalization into your targeting, this is usually the first platform I evaluate.

Roku offers deep first-party audience insights, making CTV and OTT advertising campaigns extremely relevant.

What stands out:
Billions of logged-in users

The wrong choice can inflate costs. The right one can lower CPMs and raise ROAS instantly.
