Addition of mROI constraint in optimisation

[aadityachouhan-ah]

Can we consider adding an option to the hill-climbing optimiser to mask/skip candidate spend levels for any channel where the marginal ROI (mROI) < 1, i.e., where marginal CAC > revenue_per_conversion. This guardrail prevents over-spend in the negative-return region and makes the budget recommendation safer by construction.

Hi @aadityachouhan-ah,

Thank you for contacting us.

Meridian currently supports optimization with an mROI constraint, only under a flexible budget scenario. See our documentation on Flexible budget: Target marginal ROI for more details.

If you are looking for this offering available in the fixed budget optimization scenario, we'll take your suggestion into consideration.

Our team is constantly working on improving Meridian's functionality and you may check the unreleased features on the CHANGELOG page in GitHub.

Feel free to reach out if you have any questions or suggestions regarding Meridian.

Thank you,

Google Meridian Support Team
