How can the use of dynamic dropdown fields in a marketing dashboard help in tracking customer demographics for a company like Coca-Cola?

There are several alternative methods to track marketing spend and ROI apart from using a marketing dashboard. These include:

1. Using a spreadsheet: This is a simple and cost-effective method. You can create a detailed spreadsheet where you record all your marketing expenses and the returns you get from each marketing campaign.

2. Using accounting software: Many accounting software have features that allow you to track your marketing spend and ROI.

3. Using CRM software: Some CRM software have features that allow you to track the success of your marketing campaigns.

4. Using marketing automation tools: These tools can automatically track your marketing spend and the returns you get from each campaign.

5. Hiring a marketing agency: If you have the budget, you can hire a marketing agency to track your marketing spend and ROI for you.

Google can use a marketing dashboard to track their ad spend and ROI in different regions by first entering their static inputs such as the name of the report and the event they plan to track, in this case, marketing spend. They can then customize two dynamic dropdown fields and two nested dropdown fields. For instance, they can choose to track regions with specific countries nested inside those regions. This way, they can compare budget vs actual and actual spent vs. ROI gained over any period.
