header bidding
Já ouviu falar em
header bidding? ‘ WTF
is header bidding?’
‘The Rise Of
'Header Bidding'
and The End of
The Publisher
Waterfall’

3. Agenda
▪ Why Should You Care About Header Bidding?
▪ What is Prebid?
▪ How is Header Bidding Changing Programmatic?

4. Header Bidding
A technique for publishers to make every
impression available programmatically and
ensure real-time competition.

5. The Old Way – Waterfall
Allocation
SSPs & exchanges can’t bid on
impressions they don’t see. The
waterfall is a guessing game and
not real-time.

6. Header Bidding Manifesto
1. Remove the waterfall and manual guess-work of allocating
impressions to SSP partners.
2. Make each of the publisher’s partners – including Google Ad
Exchange – compete on every impression with actual bid values.
3. Give SSPs, buyers, & data providers access to 100% of a publisher’s
supply. Better inventory, lower frequency impressions, etc.
4. Let publishers choose the marketplaces they want to work with –
niche, independent, or local players.
