You have connected your account to Perpetua and now you ready to set your target ACoS. The key question: What should it be?

We strongly recommended that your initial target ACoS be set as close to your historical ACoS as possible prior to transitioning to Perpetua. Below is a briefing of what could happen to your campaign depending on the initial target ACoS that you set.

Starting low:

Let's say your historical target ACoS was 35% and you have set your initial target ACoS at 15%.  While we understand that you may want to lower your ACoS to 15% eventually, doing so at the outset may lead to a significant drop in spend / sales. By setting your ACoS much lower than historical, you'll effectively be dropping bids on all of your targets. Unfortunately, our software won't know what targets work at those lowered bid prices at the outset, so you likely won't be wining any bids on targets that drive you sales.

Starting with a historic target ACoS:

This is an ideal ACoS rate for Perpetua's engine because of four things:

  1. It eliminates any unnecessary guessing that would otherwise have to be done by the ad engine
  2. It significantly reduces the risk of bidding less on keywords and ASINs that have performed well in your previous campaigns
  3. When the engine becomes "smarter" and becomes efficient at managing your campaigns, it will enable you to adjust your target ACoS to see what works and what doesn't.
  4. Finally, this ensures as smooth as a transition possible from your campaigns to Perpetua optimized campaigns and sets up a foundation for success.
