Frequently Asked Questions
Everything you need to know about using Seimitsu for your agency.
How does Seimitsu work with GA4?
Seimitsu connects directly to your clients' GA4 properties using secure OAuth. Once connected, you'll see all properties in a unified dashboard. There's no need to migrate data or change your existing GA4 setup - it works instantly with your current configuration.
How quickly can I get set up?
Most agencies are fully set up within 15 minutes. Simply connect your GA4 accounts, customize your branding, and you're ready to go. Your client data will start appearing immediately, with full historical data available after 24 hours.
Can I white-label reports for clients?
Yes! Our Growth plan and above include white-labeling capabilities. You can customize reports with your agency's logo, colors, and branding. Clients will see your branded dashboard and PDF reports, perfect for maintaining a professional image.
Is my clients' data secure?
Absolutely. We use enterprise-grade encryption, follow strict security protocols, and maintain SOC2 compliance. We only access the GA4 data you explicitly authorize, and your clients' data is never shared or used for any other purpose.
What happens to my existing GA4 setup?
Nothing changes with your existing GA4 configuration. Seimitsu works as an overlay to GA4, providing better visualization and reporting. All your current tracking, goals, and configurations remain exactly as they are.
Can I manage multiple client accounts?
Yes, that's what Seimitsu is built for! You can manage unlimited client GA4 properties from a single dashboard. Our interface makes it easy to switch between clients, compare performance, and generate reports for all your accounts.
Do you offer agency pricing?
Yes, our pricing scales with your client base. The Growth plan is perfect for small agencies, while Pro and Agency Plus plans offer additional features and custom solutions for larger agencies. All plans include our core time-saving features.
