Pubstack to Host Live Webinar on SSP Throttling & Its Impact on Publisher Revenue
by on 2nd Jun 2026 in News

Pubstack, the publisher monetisation platform, has announced a free live webinar taking place on Tuesday, June 16th at 3:00 PM CET, titled "Why Buyers Ignore Most Publisher Inventory: The Hidden Impact of SSP Throttling".
Led by co-founder and CSO Loïc Sfiligoï and CPO Federico Benincasa, the 45-minute session will examine one of the most overlooked dynamics in programmatic supply chains: SSP throttling, which silently filters out publisher inventory before buyers have any opportunity to evaluate it.
The session will cover:
- Why SSP throttling has become a significant and largely invisible source of revenue loss for publishers
- How high-value inventory is eliminated before it reaches the auction
- Why scaling SSP partnerships or increasing bid request volume fails to address the root cause
- What publishers can do in practice around supply-side signals, supply shaping, and structured inventory
