Setting different timeouts for desktop and mobile

Setting different timeouts for desktop and mobile

Mobile visitors are on slower connections, so bids take longer to arrive there.

The approach:
— 1. Time your bid responses separately on desktop and on a phone.
— 2. You'll usually find mobile is 200-400ms slower.
— 3. Set a tighter timeout for desktop where bids come back fast.
— 4. Give mobile a little more room so good bids aren't cut off early.
— 5. Re-check both after a week — connections and partners change.

Using one timeout for both either rushes mobile or drags desktop.

In plain English: time bids on each device and give the slower one a slightly longer deadline.
