For CRO and digital marketing agencies, A/B testing tools present a unique challenge: they need to manage multiple client projects with different traffic levels, various analytics setups, and different budgets — all from one platform. Most testing tools charge per traffic or per seat, making costs unpredictable when clients scale.
Varify.io is built for agencies: flat rates per project without traffic limits, multi-project management from a single account, a visual editor that works without access to client developers, and native integration into any existing GA4 or analytics setup of the client. No traffic-based fees per client, no surprise bills. Find the complete agency offering on the agency partner page.
What Agencies Need from an A/B Testing Tool
1. Predictable Costs per Client
When you offer a CRO retainer, you need to know your tool costs upfront. Traffic-based pricing (VWO, Convert) makes this impossible — a successful campaign that doubles client traffic also doubles your testing bill. Flat rate models enable accurate budget planning.
2. Multi-Project Management
Switching between client accounts shouldn't require constant logging in and out. Agencies need a dashboard that shows all projects, their active experiments, and results in one view.
3. No Developer Dependency
You rarely have direct access to client development teams. A visual editor that allows your CRO team to create, modify, and deploy tests without code is essential for agency speed.
4. Integration into Client Analytics
Each client has their own GA4 property, their own goals, their own reporting. The testing tool must connect independently with each client's analytics — not force them into a shared tracking system.
5. Client-Safe Reporting
Agencies need reports they can share with clients. Clear visualizations, statistical significance indicators, and exportable data.
