Bid Multipliers

The Criteo engine maximizes advertising performance while optimizing the shopper experience. It can automatically and intelligently control how much a line item delivers on each page type. In addition, bid multipliers provide campaign managers more control over managing bids at the line item level while also optimizing campaign performance goals at a page-type level.

Bid multipliers are available at the Onsite Sponsored Products line items level. In addition, campaign managers can modify bids only on enabled page types.

Bids can be increased up to 500% or decreased up to 50% on each page targeted at the line item level.

For example: If a line item bid is $1, with a bid multiplier, you can increase the Search page bid by 20% and decrease the homepage bid by 10%. The Criteo engine will optimize more delivery and performance on the search page while also allowing the control of which page types budget is mostly allocated towards.
