What are Bid Multipliers

Both automatic campaign and manual campaign have the option to utilize a bid multiplier. These multipliers allow the bids for specific prime placements and platforms to be increased by a % that is set by the advertiser. Perpetua currently only offers placement multipliers and not platform multipliers.

There are a number of placements available on Walmart - however, certain placement multipliers are restricted to only auto campaigns and not manual campaigns. Please refer to the graph below to see which placements you are able to set a multiplier on:

Platform Multipliers

As consumers are using from various devices, advertisers are able to add multipliers onto various platforms such as desktop, mobile and mWeb.


  • If you decide to use both placement and platform multipliers, they will be added together:

    For example:

    • Starting bid:


    • Buy-Box Multiplier:


    • Desktop Multiplier:


    • Resulting bid for buy-box position on desktop:

      [$3.00 * (1+60%)] + [$3.00 * (1+180%)] = $13.2
