# ROAS Optimization: Balancing D7 and D28 IAP Campaigns

**[Unity](https://daily.dev/sources/unity)** · 6 min read · 0 upvotes · 0 comments

## Summary

Unity Ads has introduced a D28 IAP ROAS optimizer alongside the existing D7 optimizer, and the recommendation is to run both simultaneously. D7 campaigns capture early spenders and provide fast feedback loops, while D28 campaigns target a distinct cohort — roughly 62% of high-value IAP converters show no spending signals in the first week. Unity Vector, powered by first-party game creation data, differentiates between these player types at bid time using cross-game behavioral patterns and aggregate cohort insights, preventing the two campaign types from cannibalizing each other. Running both windows together covers the full 28-day revenue curve and improves overall UA efficiency.
