TL;DR
What does a conversion rate optimization consultant do?
A conversion rate optimization consultant finds what stops visitors from converting on your site, then A/B tests fixes so you keep only the changes that win.
- Tests start in the first two weeks, and the audit research runs alongside them: an analytics review, user testing against a competitor, a poll, heatmaps and session recordings.
- A senior consultant leads every engagement, with analysts, developers and QA who build and check every test.
- We’ll use Nantu, our free testing tool, if you don’t have one, and we’re experienced with whatever testing tool you’re already using.
Bottom line: a senior consultant leads the work, and a team builds and checks every test.
Expert, specialist and consultant are used for the same role. Our guide to what a CRO expert is covers how the labels get used and how to hire for each. This page is about conversion rate optimization consulting with us.
Ours start testing in the first two weeks and run the audit research alongside. Later tests come from the audit’s prioritized list: we design, build, QA and launch them, read the results, and keep only the changes that win.
Who leads the work
Who leads a ConversionTeam consulting engagement?
A senior consultant leads every engagement, with analysts, developers and QA who build and check every test.
The founder behind the team
Devon Cox, Founder & President
Devon Cox is Founder & President of ConversionTeam, which has been doing conversion rate optimization for more than 18 years. He holds a B.S. in Business and Computer Science from Boston College and an MBA in Marketing & Entrepreneurship from the University of Colorado Boulder.
Devon also built Nantu, an open-source enterprise A/B testing platform, because the existing tools didn’t meet the standards his team needed. Devon is based in Denver, Colorado.
You work directly with the consultant who leads your engagement. They run the audit and the test plan and join the readouts. Behind them, analysts, developers and QA build and check every test.
What’s included
What does a CRO consulting engagement include?
Tests from the first two weeks, a CRO audit alongside them, your testing tool or our free one, and a progress report on every test.
Tests from the start, the audit alongside
Tests start in the first two weeks. The audit research runs alongside them: an analytics review, user testing against a competitor, a poll, heatmaps and session recordings. The audit is a prioritized list of fixes.
A/B tests from the audit’s list
Later tests come from the audit. We design, build, QA and launch tests from the top of that list, read the results, and keep only the changes that win. We prioritize pages with the most traffic and drop-off first.
Your testing tool, or ours
We’ll use Nantu if you don’t have a testing tool, and we’re experienced with whatever testing tool you’re already using.
A progress report on every test
You get a progress report on every test: what ran, the result, and what we test next.
What we need from your team: analytics access and a contact who can approve tests. Want a first look before an engagement? Get a free Quick Wins audit.
Who it’s for
Who is a CRO consultant for?
Sites with about 20 conversions a week or more, and teams that want a senior consultant to lead the work.
A good fit
- Sites with about 20 conversions a week or more
- Teams that want a senior consultant to lead the work, with analysts, developers and QA to build and check every test
- Teams with a testing tool already, or none at all
Not a fit yet
- A small site that has never done CRO. A one-time best-practices pass from a freelancer can make sense first.
- Sites below about 20 conversions a week. Audit and research work fits better than A/B testing there.
Consultant or agency
Should you hire a CRO consultant or an agency?
A freelancer’s best-practices pass fits a small site that has never done CRO. Once you have the traffic to test, hire a team that builds and checks tests, from an agency or a consultant backed by one.
| Where you are | What fits |
|---|---|
| A small site that has never done CRO | A one-time best-practices pass from a freelancer can make sense first. |

How do you choose a CRO consultant?

| Question to ask | ConversionTeam |
|---|---|
| What research do their tests come from? | An audit that runs alongside the first tests: analytics, user testing against a competitor, a poll, heatmaps and session recordings. |
| Do they publish a win rate and show losing tests? | 61.1% across 2,288 audited tests, with the method published. You get a progress report on every test: what ran, the result, and what we test next. |
| Who builds and checks the tests? | Analysts, developers and QA build and check every test. |
| Will you work with the person who leads? | Yes. The consultant who leads your engagement runs the audit and the test plan and joins the readouts. |

Guarantee
What is the 30% lift guarantee?
Iterate carries our 90-day, 30% lift guarantee: if winning tests haven’t delivered a 30% conversion rate improvement in your first 90 days of active testing, we keep working free for up to 3 more months until they do.
It covers consulting engagements on the same terms. How the Iterate program works.
An outstanding experience. When we went looking for help optimizing conversions, two people I hold in the highest regard - who don't even know each other - both recommended Devon. We've been blown away by their expertise, professionalism, and results.
Responsive, timely, and the results and expertise speak for themselves. We bring them in across multiple client engagements.
Devon is a real CRO rockstar. He looks at a site and immediately hones in on the opportunities for improvement, and backs up every recommendation with testing. Highly recommend.
Mike BelascoFounder & AdvisorThey provide elaborate reporting on every test, with clear KPIs where we can identify winners to implement - conversion-rate increases, more ecommerce purchases, and higher engagement. Communication is easy and their project management is excellent.
Devon was a great partner when we needed to improve our website's user experience. His team gave us a thorough audit of our top pages and a free heatmapping tool we still use today. Highly recommend, especially if you're in lead gen.
Working through tests with ConversionTeam has been great. Their project management is top-notch, and their knowledge base is what stands out - we have no plans to change the relationship any time soon.
ConversionTeam was excellent to work with and delivered exactly what we were looking for. They ran a CRO audit of our site; their insight was incredibly valuable and helped us advance toward our goals with confidence. Professional, organized, and thorough.
ConversionTeam has had a significant impact on our conversion rate - a good uplift, and especially an increase in revenue. We're impressed with their personalized approach and deep understanding of our needs.
We're seeing 210x ROI and a 22% lift in conversion rate - it's hard to measure all of their impact. We sold out of almost all our stock; we weren't ready for the lift they'd provide. They run a tight ship and always come to meetings prepared.
I couldn't be more impressed. Their team ran an in-depth audit that identified high-value opportunities, then a game plan of A/B tests to validate them - and nearly every test they recommended outperformed the control. Rigorous and data-driven, no guesswork.
We've worked with ConversionTeam since 2018 and are very happy. Their collaborative spirit and out-of-the-box ideas have significantly amplified our CRO efforts and added new dimensions to our strategy.
