Optimization success is
measured by results

Having been in this business since 2015, we've gathered a long list of clients & client results to showcase. Over the years, we've received the expert-vetted status by Upwork, which means that we are certified to be a top 1% service provider in the world's largest work network for independent professionals. This status is earned after consistently generating outstanding client feedback and going through a rigorous vetting process for skills & experience. 

On top of this, we have been a Shopify certified expert since 2016, recognized in both the marketing & store setup categories. Shopify has even used our work as an internal benchmark to vet other agencies.

We also hold multiple certifications by the highest CRO learning authority, CXL institute, to be confirmed as top professionals in our field.

I feel confident in his team
It has been a great pleasure working with Samuel and his team. He responded to my concerns each time promptly and made sure that I feel confident in his team. As for the conversion rate of our website, we will continue monitor it and see if it will increase overtime.

Very flexible partnership commitment
CRO Gurus helped us build our website from scratch to a heavily optimized website for usability (something that we didn't pay attention to before) to maximize conversion rate and transaction. They also helped us customize website functionality to better customer experience. One of the things I like most about working with CRO Gurus is their project flexibility. You are not tied to a long-term contract which allows eCommerce merchants to test the waters before committing for the long-term.

I always got what was promised
I always got what was promised. They have very solid processes in creating these services while still producing custom & valuable work. What I find most impressive about CRO Gurus is their consistency and deep knowledge of e-commerce CRO really stood out to us. Usually, small companies tend to be a bit unstructured but I don’t think I’ve ever seen a company that cared so much about the details and had honed their reports to this degree.

No Brainer to Hire
This was a great experience. Samuel is extremely detail-oriented and knows conversion rate optimization in and out. As a busy founder, I don’t always have the time to project manage a freelancer and Samuel not only stuck to his word but delivered an extremely detailed audit that made us feel confident in hiring his team to implement the recommendations after the audit. In comparison to other freelancers I interviewed, Samuel was the only one that specialized in conversion which made him a no brainer to hire him for our needs.

CRO Gurus will treat your business as their business
It’s been about a year since I started working with CRO Gurus and there has been a lot of things that we’ve done on the website and other factors that led the business to growing up to 6-7x in revenue. Working with Samuel and his team has been quite very easy and valuable for my business. I’d say that you can trust CRO Gurus looking after what you need because they will treat your business as their business. They are not going to overcharge you of something that is not going to help you.

Full Website Audit
CRO Gurus provided exceptional help and professionalism for my website. They did a full audit of my website and made several changes that have helped to optimize my customer experience, such as website flow, cart optimization, improving consistency, checking UX on several browsers and much more. They also helped me set up email templates for new customers, returning customers, and abandoned carts that are tailored to my customer base. I will definitely be working with them again in the future. Thank you!

Deep, insightful, and precise conversion rate optimization report
Exceptionally clear, detailed and insightful Conversion Rate Optimisation report. Very patient with my questions. Samuel is methodical and diligent in execution with well-reasoned rationales behind his recommendations. He was also good and at managing expectations. The report I received was deep, insightful and precise. In a couple of months of sustained traffic, I will likely rehire Samuel to perform a second audit, so that I can iteratively improve site performance. Highly recommended.

His SEO strategies are very sound!
Samuel has been helping us in generating an SEO strategy for our consulting business. The goal of the project was to generate interested, leads through organic search. We basically wanted to have our landing pages rank well enough on Google so that these leads find us when they are googling our services. We have been implementing his SEO strategy for 5 months now, in order to improve our domain reputation with Google and now we find that we rank pretty well for most things we are selling. Wholeheartedly recommend to use him for ongoing SEO as his strategies are very sound and he doesn’t just generate a plan for getting a ton of traffic that don’t buy but always seeks to generate the right kind of traffic as well.

Shopify Store Design
We selected Samuel Larsen to build our new Bergstop online shop and have been very satisfied by his design and services. He explained in detail the options and consequences and had the patience to go through changes which came up in the process. We still go back to him for mayor changes and regular maintenance, and are very happy about the good collaboration.

So, are you ready to get the most out of your store?

While I’d like to think we can deliver fantastic work for everyone, you’ll benefit the most out of the engagement if:

1. You let your business goals and metrics dictate design.
2. You appreciate direct and honest communication (even if it hurts sometimes).
3. You aren’t interested in micro-managing and babysitting.

If you’re looking for someone to like this, then we probably will work well together.If you see a possible fit, simply apply to work with us and we’ll discuss the details of your project.
