In-Flight Optimizations

Bids

Bids are where you determine how much you want your line item to offer in order to gain an impression and enter an auction. The bid you input does not include fees such as third party providers, audiences fees or others. Because of this, don't be alarmed if your CPM is a little bit higher than the bid you input.

• Reducing base/max bids on the low performing line items would decrease their effects on the campaign and could improve the performance

• Increasing the bids on the top-performing line items would provide more room to the DSP for bidding on them

• Pausing the line items with the lowest performances and moving their remaining budgets into performing lines may increase the overall performance

• Criteo sees the best performance for Offsite Display line items that bid in the $5-8 range
  

Frequency Caps

Frequency caps are where you can limit the number of times an individual shopper sees your ad. This can help you eliminate waste as someone who has seen your ad 17 times is unlikely to convert if you show them your ad one more time. Better to allocate that effort to someone who has seen your ad only two or three times if possible.

• Decreasing the frequency cap on the low-performing line items would shrink their impact on campaign performance

• Increasing the frequency cap on the top-performing line items would expand their impact on campaign performance

• To increase delivery, remove or increase line item frequency cap threshold

• For best performance, we recommend starting with a tighter frequency cap and then increasing as needed for scale, as long as the client values view-through

  • This will avoid hitting the user multiple times (increasing spend) while within the attribution window

Audiences

Audiences only apply Onsite Display and Offsite Display campaign types. Audiences are where you select a group of shoppers you want to see your ads.

• On products that are not purchased frequently (e.g. electronics), we recommend exclude recent purchasers. This will allow you to spend your campaign budgets on users that didn’t yet purchase your product.

• Audience not scaling: Audience size optimization.

  • Increase lookback window gradually, using 30 days at a time as a recommendation

  • Add more categories or brands

• Audience not "performing" (low sales): Test out new audiences

  • Create audiences of users that have added products to cart with an exclusion of those that have purchased

  • Test shorter lookback windows to target users who have more recently shown interest

Creative

Creatives only apply Onsite Display and Offsite Display campaign types. Creatives are the active image that appears to the shopper on the webpage.

  • Mobile: 320x50, 300x250, 300x480, 300x50

• 320 x 50, 300 x 250, 728 x 90, 300 x 600 accesses 90% of inventory
