A fast, practical deep dive into The Trade Desk's move to label all SSPs as "resellers" — what that label actually means, why it has a bad rap, and where it's fair vs. misleading. Gareth breaks down value-add resellers (e.g., unique widgets/placements) vs. pure pass-through reselling, explains OpenPath in plain English, and demystifies the Transaction ID debate: what it is, why TTD wants it, and how it impacts buy-side efficiency and supply transparency.

We wrap with actionable steps for traders — how to pressure-test paths, when to go direct with publishers/PMPs, and how to optimize beyond a basic domain list.

Here's What You'll Learn

• Reseller ≠ automatically bad: the original IAB intent vs. today's nuanced reality.

• OpenPath vs. exchanges: what "direct to publisher" actually changes (and what it doesn't).

• Transaction ID, explained simply: one auction ➝ one ID ➝ fewer dupes and smarter SPO.

• How to buy smarter right now: talk to publishers, ask for goal-specific PMPs, and evaluate placements/experiences — not just domains.

• Buyer playbook upgrades: site list ➝ supply-path & placement-level decisions; pair KPI outcomes with quality signals (viewability, density, layout).
