Increase conversion rates, customer happiness and profitability.


A smarter way to increase profits for your eCommerce store.


I use conversion optimization (A/B tests), UX research and analytics to increase customer experiences and business profits.


Hey, I’m Chris Marsh.

I help online stores boost their customer happiness and business profits.

There’s no magic or luck needed, I use the same methods that led to Amazon’s incredible success:

     User Research and Experimentation (or CRO).

Recently I drove a Return on Investment of 19:1  through a CRO program for an eCommerce brand.

This returned over €3 million in extra revenue for my client (plus many key learnings of their audience). 

I’m determined to grow your conversion rates, customer happiness and profits.


Don’t leave money on the table:

CRO & UX Research helps you become customer-centric, and boost profits.

Companies who put UX research and customer-centered design at their core see a 228% higher ROI than the S&P 500. (source:


75% of businesses think they are customer-centric.

Only 30% of customers agree.

This is a gap of opportunity.


be customer-focused,
and stand out from competitors. 


My 3 Step Process

Guaranteed to make your website more lovable (customer-centric) and more profitable.

1. UX research to uncover your valuable insights

You’ll learn WHERE users struggle, and WHY they get confused and leave your site. Uncover their needs and fears.

Discover how you can transform your customers experience and profits. 

2. Update your site with Usability fixes and quick-wins

Now you have plenty of quick-wins to implement straight away. These are easy to filter, prioritise and act on.

Your website will improve in usability,  clarity and profitability.

3. A/B Test, measure, learn and repeat

You get data and insight-led hypotheses and a CRO Roadmap.  

Ruthless prioritization helps lift your chances of success.

Your CRO Roadmap and Knowledge-base evolves over time. This continues to drive more insights and revenue-boosting opportunities.

Reliable Freelance Conversion Optimisation (CRO)  

I help your store become more customer-centric, so more customers will convert (buy).

I do this through research – to uncover why some people don’t convert.

Then I help you launch quick-wins and A/B split test optimisations.

You get a robust CRO roadmap and knowledge-base.
We learn from test to test.
The more we learn and test, the faster you grow.

Your purpose-built CRO Roadmap and Knowledge-base software helps you…
see an overview of insights (real customer observations), and filter them by area of site or theme
✅ see how hypotheses are directly linked to insights and data
✅ see clear next steps (prioritized hypotheses)


UX Research: Analytics and Insights

I use a variety of tools and techniques to peak into your customers mind. Learn why your users don’t complete their key tasks,  why they leave, and why they don’t buy (convert).

You’ll learn where your website needs optimising and learn why users aren’t converting.

Expert Review

An expert review of your website involves a thorough analysis based on conversion and usability guidelines. It’s the quickest route to find and remove obvious conversion blockers. 

You’ll uncover dozen’s of opportunities to help you improve your Conversion Rates.

User Testing

I record 5 users completing tasks on your website, and analyse their behaviour.

This method uncovers pain-points that your users face every day. We can then eliminate these issues, and make your website more loveable and profitable.

Conversion Optimisation (CRO)

After initial research, and launching quick-wins, I can help you organise a CRO roadmap and run ongoing optimisation. This will further increase your Conversion Rates and prevent you from launching changes that bleed money.

I’ve specialised in CRO for over four years and helped brands increase annual revenue by over €3 million  🙌

Which method should I use?

The most impactful way to start is to research using multiple methods at once: Analytics, an Expert Review and User Testing. Then you’ll have a smattering of quick-wins to implement and huge opportunities to optimise your website.

The cheapest way to start is to use one or two research methods. This lean approach will provide a drip-feed of quick-wins and opportunities after each research method is complete. If this sounds good for you, I recommend you start with an Expert Review.
