From simple redesign tests to complex API-based tests and multi-platform experiments, we got you covered!

A/B ‘Split’ Testing

A/B test development is our core service, and we’ve mastered every part of the design, development, and QA process. Our tests are developed rapidly yet meticulously, and our expertise incorporates numerous tools and tactics outside the testing platform itself. Nobody develops Split tests quite like BrillMark.

Multivariate Testing

Multivariate testing takes split testing to the next level, both in terms of complexity and potential benefits. It’s crucial that these tests are run flawlessly in order to gain accurate data and make accurate conclusions, and as always our team has you covered.

Hotjar Integration

Split testing and heatmaps go hand in hand, but tracking heatmap data at the variation level requires additional setup and development. For this reason, we are ready to properly integrate popular heatmap suite Hotjar for our clients.

API Based Testing

We have no problem developing complex tests that interact directly with APIs. Whether you want to pull data from an internal service or external AWS service we got you covered.

Testing Platform Setup

Setting up a new testing platform may seem like a trivial task, but improper installation is a common problem that results in inaccurate testing data. After working with hundreds of sites, we know how to do it right, whether deploying directly on the site or through tag manager.

Marketing Platform Integration

Marketing platforms like Marketo, Hubspot, or Clearbit are a huge expense, and failing to integrate them with a testing platform is a common oversight that, if prevented, could save you significant amounts of resources. We can quickly and easily integrate your platforms, allowing you to collect audience data through your marketing platform and then target users directly through your testing platform.

Tag Creation & Management

Testing development often requires setting up and managing tags to track goals, trigger events, and more. We’ve worked with all types of tag management systems, and most importantly, we understand how critical tag management is to getting accurate testing results.

CRO Analytics

While we are focused on building and running accurate experiments, we understand that every platform captures and displays testing results differently. When needed, we’ll happily help you develop additional reports to identify the exact data and insights you are looking for.

The BrillMark Process

Interested in working with BrillMark? Our process is designed to seamlessly integrate with your team and your campaigns.


Website experimentation starts with auditing your website to identify critical areas and then creating improvement strategies to be tested against the Control. This can be done by a CRO agency or your own in-house team. Once you have your testing requirements in place, it’s time for BrillMark to take over.


Our role starts when you decide what are the requirements and parameters for your website experiment. Our experts will design a technical specification for the proposed test, assess the approximate number of hours required, and send you an estimated quote for your approval.


Once the technical specification has been approved, our team will develop the test locally, move the test to testing platform of your choice, and apply the optimal platform-specific settings afterwards. Next, the developed test is sent to our quality assurance department for rigorous review, and once test acceptance criteria is finalized, and the test is sent to you for final approval.


Once you’ve reviewed and approved the developed test, it’s time to go live! We will monitor the tests closely for 24 to 48 hours to ensure that the test is performing as designed, and that all goals and metrics are being tracked correctly.

“Working with BrillMark to help our CRO agency has been a fantastic experience. The team is responsive, thorough, and act as an extension of our in-house team. I highly recommend them to anyone looking for quality development resources”
