Our AB testing process

From hypothesis to winner.

  1. 01

    Research & Ideation

    We uncover opportunities through competitor analysis, website audits and market research, then turn them into test hypotheses.

  2. 02

    Development & Launch

    Experienced developers build each experiment and rigorously QA it before it goes live, so your visitors only see polished experiences.

  3. 03

    Analysis

    We dig into the data to understand it's impact on customer behavior and revenue.

  4. 04

    Iterate & Implement

    We refine and retest, so only the changes that prove their impact are rolled out permanently.

The benefits of experimentation

Stop arguing about opinions.
Let's test them.

Iterate is a UK-based CRO and A/B testing agency that turns website traffic into revenue. We take the guesswork out of growth through three core areas: research and experimentation, test development and QA, and data-driven analysis and iteration.

01

Turn more visitors into customers.

By testing different variations, you can optimise your website continuously to improve the visitor experience and general conversion rate.

02

Make bigger decisions with smaller risks.

Relying on assumptions can lead to costly mistakes. A/B testing mitigates risk for all teams by providing data that proves what actually works for their specific audiences.

03

Understand what customers actually respond to.

By running A/B tests, you can identify patterns in user behavior and refine your marketing strategy according to how different segments of your audience respond to different variations.

04

Find revenue hiding in your existing traffic.

What you think is a smooth, enjoyable experience for users is not necessarily what your audience thinks. Insights from A/B tests can help you find out exactly what your customers enjoy about your site.

05

Turn UX changes into measurable outcomes.

Instead of relying on opinions or broad industry trends, the data your tests provide helps you to prioritize changes that will have the greatest impact on your results.

06

Build a culture of continuous improvement.

Once experimentation becomes a habit, you can ensure that you're getting the best possible results for your time and budget.

Case studies

We don't just talk about tests.

A look at the kind of experiments we've run recently.

UX and design

Mobile header redesign

The navigation header needed modernising, and so we tested multiple variations of an updated design.

The final iteration showed positive engagement with the search bar, and less journey resets via logo clicks

Merchandising

Product upsell in the cart

Tasked to increased aftercare product sales, we added an upsell module to the cart, supporting customers in finding relevant care products at the right point in the journey.

Further iterations included adding a 'Quick add to Bag' CTA and only showing relevant aftercare products based on what the customer had in the cart.

Questions

Frequently asked questions

How quickly can we start?

Research and ideation can begin within a couple of weeks of the kickoff call. A development or full-ownership engagement usually ships its first test in the first month, once tracking and access are in place.

Do we need developers on our side?

For most web tests, no. We build in your experimentation platform. When a change needs the codebase, we spec it clearly and work alongside your engineers rather than around them.

Which tools do you work with?

The ones you already run. GA4, BigQuery, Shopify, Optimizely, VWO, Contentsquare, and the rest of the list above. If the data is trustworthy, we can test on top of it.

What does a typical month look like?

A short planning session, tests in build or in flight, and a readout that ends in a decision. You always know what is live, what is next, and what we learned.

How do you measure success?

Against the commercial metric we agree up front, not a pile of micro-conversions. We also track how many tests you ship, and how often a result changes a roadmap decision.
