Live Webinar Supply Intelligence Webinar

# Why buyers ignore *most* publisher inventory.

The hidden impact of SSP throttling.

 Premium publishers are producing valuable inventory, yet much of it is filtered by SSPs before buyers even evaluate it.

 Join Pubstack to understand why SSP throttling has become a growing revenue problem, what it means for publisher monetisation, and how publishers are adapting their supply strategies to improve inventory visibility and valuation.

Agenda

## What you'll learn.

 In just 45 minutes, you'll learn what happens before buyers even evaluate your inventory — and what publishers can change immediately to improve visibility, reduce waste and increase revenue potential.

1. 01Why SSP throttling has become a growing revenue problem for publishers.
2. 02Why valuable inventory gets filtered before buyers even see it.
3. 03Why adding more SSPs or sending more bid requests is no longer enough.
4. 04How publishers are reshaping supply to make inventory easier for buyers to evaluate.
5. 05How stronger supply-side signals can help publishers increase evaluated impressions, improve CPM performance and unlock more value from the same inventory.
