What is Demand Hub?

Demand Hub is an attention-driven demand layer developed by Opti Digital.

It acts as a strategic bridge between publishers and premium advertisers, providing access to curated demand, Private Marketplace (PMP) deals, and high-impact formats (such as social-inspired carousel ads).

This allows publishers to unlock incremental revenue (+5% to +10%)
