How should I use ROAS in the Rule Engine?
When selecting ROAS as a metric, the system considers it as a Constant Value (not as a percentage).
E.g. If the cost is $100 and the total conversion value is $500, Google Ads would report Conv Value / Cost to be 5. This is multiplied by 100 to get the ROAS which in this case will be 500%.
How do I duplicate a recipe?
If you want to create a duplicate of the recipe in the same account, go to the all recipes main page and under "Actions", press "Duplicate".
However, if you were looking to use the recipe across accounts, you would have to convert it into a Global Recipe, making it available across all your accounts without the need to copy it onto each one manually.
Global Recipes can also be included in Custom Workouts and can be accessed directly from the Optimizations tab.
You can convert a recipe to a global recipe on the recipe pages, by modifying it through the right-side actions, and use the same action button to revert it back to an account-specific recipe as well.
How to restrict bids changed in Rule Engine?
You can restrict the maximum bid to go up to a limited number using formulas, a number (like USD 10), a metric (like Top Position CPC) or an expression.
For example, you can limit the maximum bid to not be higher than 125% of the current bid.
Optimizing Automated Bidding and Portfolio Strategies
Automated Bidding and Portfolio strategies are fully automated by Google Ads, and no 3rd party tool will be able to edit them, as Google aggregates the performance data for everything in the portfolio and uses that to determine bids.
The workaround we've created for this, based on the restriction Google has, is changing the target at the ad group level, using the Target CPA or Target ROAS recipes in the Rule Engine.
These recipes, however, only work with standard strategies.
