Tools BrillMark uses for A/B test QA

Our QA team works across the leading platforms and testing tools in CRO. Here’s what’s in our stack:

Testing platforms

Cross-browser & device

Analytics & goal validation

Tracking & project management

What is quality assurance in A/B testing?

Quality assurance (QA) in A/B testing is the systematic process of verifying that an experiment is set up correctly, functions as intended, and tracks conversions accurately — before it goes live and after.

Without QA, you risk making major business decisions based on data from a broken test. A flicker on load, a misfiring goal event, or a variation that only breaks on Safari — these are the silent killers of CRO programs.

BrillMark's QA team is embedded in the experiment lifecycle from the moment an LOE is approved — not as an afterthought, but as a core part of how every test gets built.

BrillMark Referral Plan

Because sharing is caring

Here at BrillMark we create amazing A/B tests, we develop high converting websites and we value our clients and their opinion. Our clients think we’re great at what we do, so we decided to reward them for sharing their opinion with others by giving them 10% referral fee. Now you can join too, even if you’re not currently our client.

We value simplicity and transparency—our referral program reflects that.

YOU ARE A CLIENT

As a current BrillMark client, you’ll receive 10% of total contract value in lieu of dev work added to your current plan after we receive the payment from your referral.Example: Your referral signs up for our 25 hour bucket – total contract value is $2500 / 10% = $250.Our hourly rate is $100 which means we will add 2.5 hours to your monthly total, for each month the client you referred works with us (for up to 12 months).

YOU ARE (NOT YET) A CLIENT

As a new participant, you’ll receive 10% of total contract value payable to you after the individual/company you referred signs a contract and makes a payment.Example:
Your referral signs up for our 25 hour bucket – total contract value is $2500 / 10% = $250.You will get $250 once the client has made the payment.
