<b>A common mistake: the same partner bidding twice</b>

A frequent setup slip is wiring one demand partner to bid both client-side (in the browser) and server-side at once. They compete with themselves.

Why it matters: it wastes auction time, can double-count, and occasionally lets a partner win against their own lower bid — messy and slower for no gain.

Tiny example: Partner X bids $2.00 in the browser and $2.10 through a server in the same auction. Now your wrapper juggles two bids from one company that should have sent one.

One thing to try: ask for a list of partners by path (browser vs server). Any name appearing in both is worth a second look.

<b>In plain English:</b> the same buyer shouldn't bid twice in one auction — check for duplicates.
