Why Agencies Choose Mida for Client Testing

CRO agencies need a tool that is cheap to pilot, simple to hand off, and flexible enough to work across dozens of client stacks. Mida was built for that workflow.

Free Sandbox for Pilots

Run up to 100,000 Monthly Tested Users on the free plan with no credit card required. Prove ROI on a client site before asking them to commit to a paid plan. Most agencies sell Mida after one winning test.

Visual Editor for Your Team

Build test variants without code so CRO strategists, designers and marketers can launch tests without waiting on engineering time. Use the visual editor for headlines, images, CTAs and layout changes, or the code editor for custom JavaScript and CSS.

Multi-Client Agency Portal

Manage all clients from one account with the Agency Plan. Give each client their own project workspace or their own account. Switch between clients with one click. Pool tested users or let clients pay for themselves. Learn more about the Partner Program.

GA4 Reporting Clients Already Trust

Connect each client's GA4 property in one click. Experiment exposure and conversion events flow into their existing analytics so they can verify results in the dashboards they already use. No custom event setup or Measurement Protocol configuration required.

15KB Script for Client Sites

Mida uses a compressed 15KB script, lighter than most competitors. Clients see minimal performance impact, which is critical when you pitch CRO to ecommerce brands or publishers that obsess over Core Web Vitals. Read the speed benchmark.

Partner Pricing and Certification

Get flexible pricing shaped around how your agency works: pooled or per-client, paid by you or paid by them. Earn 25% commission on client-paid plans or pass it on as a discount. Get certified and listed in the CRO agency directory with a Certified Partner badge.

Pilot a client site with the free Sandbox

Use case: New client pilots, small business clients under 100,000 visitors per month, proof-of-concept tests before a formal CRO program.

Manage multiple clients with the Agency Plan

Frequently Asked Questions

Can I test client sites for free before they pay? +
Yes. The free Sandbox plan covers up to 100,000 Monthly Tested Users with no credit card required. Use it to run proof-of-concept tests on client sites before they commit to a paid plan. Most agencies sell Mida after one winning test on the free tier.
How does partner pricing work? +
Partner pricing depends on how many clients you run and whether you or they pay Mida. You can manage all clients as projects in one agency account with pooled tested users, or give each client their own separate account. If clients pay Mida directly, you can choose between a 25% recurring commission and passing that discount to the client. Pricing is quoted on request once you are a Certified Partner.
Do I need developers to run tests? +
A developer adds the Mida snippet to a client site once. After that, your CRO strategists, designers and marketers can create test variants with the visual editor without code. For complex changes that need custom JavaScript or CSS, use the code editor or ask Mida to build the variant as part of the build escalation benefit for partners.
Can clients see results in their own GA4 account? +
Yes. Connect their GA4 property from the Mida dashboard and experiment exposure and conversion events flow into their existing analytics. Clients can verify test results in the GA4 dashboards they already trust without custom event setup or Measurement Protocol configuration.
What is the Certified Partner program? +

Once certified, you get a badge for your site and LinkedIn, priority in the CRO agency directory, partner pricing, priority support, and build escalation for complex variants. Apply after a quarter of paid client testing. Learn more on the Partner Program page.
Can clients see results in their own analytics? +
