This section provides a variety of scenarios that you can use to create budget
allocation optimizations:

- [Fixed budget scenario: Maximize ROI or incremental KPI](https://developers.google.com/meridian/docs/user-guide/fixed-budget-maximize-roi)
- [Flexible budget scenario: Target minimum ROI](https://developers.google.com/meridian/docs/user-guide/flexible-budget-minimum-roi)
- [Flexible budget scenario: Target marginal ROI](https://developers.google.com/meridian/docs/user-guide/flexible-budget-marginal-roi)

If you are using reach and frequency data for one or more channels, you can
[obtain the optimal frequency](https://developers.google.com/meridian/docs/user-guide/optimize-frequency) for
those channels.

Additionally, you can generate:

- [HTML two-page report with visualizations](https://developers.google.com/meridian/docs/user-guide/generate-optimization-report)
- [Non-optimized or optimized summaries](https://developers.google.com/meridian/docs/user-guide/generate-optimization-results-summary)
- [Individual optimized visualizations](https://developers.google.com/meridian/docs/user-guide/plot-optimization-visualizations)
