How should I organize and implement subaccounts?

You can organize subaccounts based on different strategies:

Client/Environment Segmentation:

{USERNAME}-subaccount-clientA_production:{PASSWORD}
{USERNAME}-subaccount-clientA_staging:{PASSWORD}

Department/Project Structure:

{USERNAME}-subaccount-marketing_analytics:{PASSWORD}
{USERNAME}-subaccount-project_alpha_dev:{PASSWORD}

Advanced Implementations (with targeting):

# Geographic targeting
{USERNAME}-subaccount-client1-country-US:{PASSWORD}

# Device targeting
{USERNAME}-subaccount-client1-device-mobile:{PASSWORD}

# Combined parameters
{USERNAME}-subaccount-client1-country-US-device-mobile-session-123:{PASSWORD}
