I highly recommend any company to work with conversion optimization expert, Samuel, in particular. As a person who has viewed multiple websites and have analyzed data upon data, Samuel's suggestions definitely works much better than mine.

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.

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.

The thing I appreciate the most about CRO Gurus is reliability. CRO Gurus ticked all the checkbox there. After analyzing our data, they have provided us with a comprehensive checklist, an audit breakdown both UX and technical and they also help us implement those changes for us so I can focus more on the important things in my business.

Vancouver, British Columbia

Their consistency and deep knowledge of e-commerce CRO really stood out to us.

The deliverables were very well made & professional. They explained things thoroughly every time & I rarely had any questions about the suggestions. The results were difficult to measure from the data perspective since I started advertising right away. With all of these clients though I was very comfortable with the sites that I was now guiding traffic to (something that wasn’t the case beforehand). I always got what was promised (although often last minute but still). They have very solid processes in creating these services while still producing custom & valuable work. I always got all my questions answered within 24 hours. 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.

Not only that, but they were then able to go and implement all of the changes they stated in an incredibly impressive regard, and exactly how we wanted them to look.

A professional team committed to improve your store

I worked with Samuel and his team over 8 months to boost our conversion rate, the team are excellent. We had weekly updates to discus issues and explore possible strategies. Since there was an issue with our cookie banner and subsequent analytics ( I only recently fixed this bug) it is hard to give an exact figure on our conversion boost but I estimate our conversion rate is up 25-30%. based on revenue. If you are looking for a professional CRO team committed to improving your webstore, definitely consider Samuel and co.

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.

They will save you so much time and mone

I re-designed my whole website with a design company and it ended up being a flop. I had Samuel and his team come in and do a full audit. It was so comprehensive and helpful, there was so much I didn't know about how to build a website that converts. I think before you even consider a re-design or re-build, consult with Samuel, as in the end, they will save you so much time and money. Highly recommend.

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.

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.

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.

World Wine

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.

April 6, 2022

Their consistency and deep knowledge of e-commerce CRO really stood out to us.

The deliverables were very well made & professional. They explained things thoroughly every time & I rarely had any questions about the suggestions. The results were difficult to measure from the data perspective since I started advertising right away. With all of these clients though I was very comfortable with the sites that I was now guiding traffic to (something that wasn’t the case beforehand). I always got what was promised (although often last minute but still). They have very solid processes in creating these services while still producing custom & valuable work. I always got all my questions answered within 24 hours. 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.
