Portfolios
Portfolios are a group of campaigns that you can organize to meet your advertising needs. Create portfolios by brand, product category, or by season to provide structure and manage your advertising activity.
You can track portfolio performance in the campaign manager, create reports for campaigns by portfolio, and see spend allocated by portfolio in your billing statements.
Portfolios within your advertising account do not compete against each other to help ensure that best performing campaigns continue to show to the customer.
Portfolios can simplify your day-to-day campaign management in multiple ways:
Multi brand management – Group your campaigns by brand, business line or season to reflect your marketing needs.
Budget caps – Define a date range or recurring monthly budget cap and ensure your campaign spends don’t exceed your desired marketing needs.
Track Performance – Review portfolio performance and create reports for campaigns by portfolio.
Streamlined billing – Simplified billing details broken down by aggregated portfolio spend in each billing cycle.
