Feedback summary: 

Conversion rates grew almost 50%, and a popular sales period generated expanded revenue. Transparent and communicative, Growcode provided regular updates and made key contacts available at any time. Their ability to support decisions with data provided valuable peace of mind.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I’m the CEO and owner of MyGiftDNA.pl, an online store that sells personalized, unique gifts for every occasion imaginable, from birthdays to Christmas to fiftieth wedding anniversaries.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Growcode?

We wanted to boost our mobile and desktop conversion rates without burdening our in-house development team.

What were your goals for this project?

We were aiming for a 25% conversion rate increase. Anything above that would be a bonus. We also wanted to clearly measure the impact this boost in conversions would have on revenue.

SOLUTION

How did you select this vendor?

In a nutshell, we were convinced by Growcode’s track record. They provided us with several case studies related to our industry, and their client list was very impressive.

Describe the project in detail.

Growcode has conducted over 40 conversion rate experiments in our year-long cooperation. They began by performing an audit and brainstorming ideas for potential changes. Each theory was A/B tested, and only the highest performers were implemented. Many of their efforts revolved around making modifications to our shopping cart, checkout, product, and category pages.

What was the team composition?

We were assigned a dedicated team. Most of our interactions were with a team leader, but we also had access to specific team members if we needed it. The team was comprised of a project manager, a graphic designer, a UX specialist, and several frontend developers.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

We saw a 40% boost in our overall conversion rate for a cost-effective price. Additionally, our holiday shopping frenzy lasted a week longer than it usually does!

How effective was the workflow between your team and theirs?

Their communication was effective and clear, and they provided us with regular progress updates. Our progress was slower than I would have liked at times, but, overall, I can’t complain. Their team leader was also available to contact directly at all times.

What did you find most impressive about this company?

Their holistic methodology and technical expertise gave me a lot of confidence. They approach e-commerce optimization comprehensively, covering everything from data analysis to design and coding.

Are there any areas for improvement?

My one criticism was that the project could have been faster. I would happily have paid the same amount for half of the period and double the intensity.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I'm head of marketing at Hairstore. We sell haircare products like cosmetics, small electronic goods, and professional equipment. We also focus on high-quality face and body cosmetics. We already sell 250 brands and are constantly looking for new, interesting products. We aim to create a place where customers can buy high-quality cosmetics with fast, inexpensive delivery.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Growcode?

We wanted to optimize our conversion rate while upgrading our online storefront. 

What were your goals for this project?

We wanted to achieve at least a 10% lift in our conversion rate. Ideally, we wanted to see a 20% to 40% increase. 

SOLUTION

How did you select this vendor?

Growcode spoke with us on the phone and conducted a short business analysis to understand our situation. Next, they prepared a webinar to demonstrate how they could improve our store. Finally, we had a short video call to discuss working together.

Their track record was convincing, and we liked that they made concrete predictions about our conversion rate. They guaranteed a 10% increase and offered a full money-back guarantee.

Can you go into detail about the services they provided and the scope of the project?

The project took six months. During this time, Growcode conducted four optimization sprints. Each sprint had seven steps: analyzing user behavior, creating recommendations from data, designing low-fidelity prototypes, designing graphics, coding in Swift, running A/B tests, and analyzing implementations. We had different strategies for mobile and desktop. 

Overall, they tested dozens of hypotheses and more than 25 designs. During each sprint, we tested the effectiveness of our unique selling proposition, the strength of our communication about free delivery, and the effectiveness of our new designs. 

What was the team composition?

We had a team leader, a digital analyst, a UX specialist, a graphic designer, and a web developer. Our point of contact was the team leader. We could also contact the executive team to discuss the project.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

The statistical significance of the first sprint wasn't sufficient. After the second sprint, however, we saw a 10% conversion rate increase on mobile and an 8% increase on desktop. The third sprint boosted our average order value by 17% on mobile and increased desktop conversions by 9%. The fourth sprint improved our desktop conversion rate by 11%.

How was project management arranged and how effective was it?

We used Basecamp to manage the whole project and had a video conference to discuss the results of every milestone. We had a direct phone number for the team lead. When we got stuck and didn’t respond, they kindly reminded us to stay on the right track.

What did you find most impressive about this company?

The quality of our communication was a big positive. Growcode described benchmarks clearly and kept us on the right track. We could measure the results of their work and specifically tie them to additional revenue, which made it easy to gauge a clear ROI.

Conducting the whole project without involving our web developers was also great. It took only a few minutes at the beginning of our cooperation to implement a small JavaScript snippet. 

Are there any areas where they can improve?

The first analysis could have been more in-depth. It would have been good to get a clear, early idea of what was possible.

BACKGROUND

Please describe your company and your position there.

I am the CEO of XSTAR, the parent company of the hotel club Triverna. The club is an e-commerce firm that offers deals to its members.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Growcode?

We wanted to optimize our conversion rate. We were eager to generate more transactions without necessarily increasing our traffic.

What were your goals for this project?

We wanted to increase our conversion rate by 40% in six months. Growcode’s reputation for speed matched our strict schedule, and we expected them to act more as a partner than a pre-packaged solution.

SOLUTION

How did you select this vendor?

I had heard about the company before and liked their content and case studies. They initially did one optimization sprint as a pilot project for us. We then agreed to a six-month engagement.

Describe the project in detail.

The Growcode team conducted five optimization sprints, each of which featured A/B testing over a period of 10-14 days. They tested new product page designs, checkout forms, new sales incentives, and marketing communication.

What was the team composition?

Both the team leader and Pawel (COO and co-founder, Growcode) were in regular contact. We communicated through Basecamp, email, videoconferences, and had a direct phone number. We also worked with two web developers, a digital analyst, a graphic designer, and a UX specialist.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

We achieved a 41.5% uplift in conversion rate. All changes were measured with A/B tests.

How effective was the workflow between your team and theirs?

We cooperated closely and we were always aware of the project’s status.

What did you find most impressive about this company?

They delivered tangible results and they took care of the whole technical dimension independently.

Are there any areas for improvement?

We would have appreciated a quicker response when we reported bugs.

BACKGROUND

Please describe your company and your position there.

I lead the e-commerce department at BANDI Cosmetics, an award-winning cosmetic company established in 1986. Recognized for our high quality, consumer satisfaction, and dedication to innovative formulas based on modern technology and scientific study, we sell more than one hundred industry-leading retail products to beauty salons and spas. 

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Growcode?

We hired Growcode to optimize our conversion rates. 

What were your goals for this project?

We had several goals. In addition to improving the UX of our online storefront, we also wanted to increase our conversion rates by 30 - 40%. We wanted the project completed in six months, but without engaging our web developers, which would ultimately slow progress.

SOLUTION

How did you select this vendor?

We sought a company that would provide more than just a report of improvement areas. We needed a vendor who would complete the bulk of the work in design mockups, code implementation, and extensive A/B testing. A colleague strongly recommended Growcode, and we knew they were conversion rate optimization experts. 

Describe the project in detail.

Growcode conducted an initial analysis and presented us with an estimated conversion uplift plan. This was useful in establishing clear ROI expectations. Over the course of six months, they executed three large optimization sprints. Each sprint consisted of seven steps and focused on updates in the communication, UX, and design. With new designs for both desktop and mobile, the testing roadmap was constantly evolving in response to user feedback and testing to ensure the products were generating results. 

What was the team composition?

The team was comprised of a team leader, UX specialist, web analyst, graphic designer, and a web developer.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Compared to last year, online revenue was significantly higher. We realized a 22% improvement in our desktop conversion rate and a 51% jump for mobile. 

How effective was the workflow between your team and theirs?

I could not have hoped for a more effective workflow. The team was always prompt, fast, and reliable. 

What did you find most impressive about this company?

They communicated well and delivered dramatic results, all without having to engage our web developers in the least. 

Are there any areas for improvement?

They currently use SwiftSwap to change our website independently, but an upgrade would facilitate easier previews of new designs.

Please describe your company and your position there.

I’m the CEO and founder of Abriga. Halier, one of our brands, is an e-commerce store focusing on haircare products. We craft beautiful, unique products and place great importance on brand identity. Everything depends on good timing, innovative ideas, and willingness to contribute.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Growcode?

We had two main goals: optimizing our online storefront and improving our e-commerce conversion rate. 

What were your goals for this project?

We aimed for a 20% lift in revenue.

SOLUTION

How did you select this vendor?

We'd worked with Growcode previously and had positive experiences. It's important that we achieve results and meet deadlines; Growcode consistently over delivers both. They also conduct optimization projects without engaging our developers, so we don't incur any additional costs.

Describe the project in detail.

We started with a kickoff meeting, then conducted two optimization sprints. Each spring had seven steps: analyzing user behavior, creating recommendations based on data, designing low-fidelity prototypes, designing graphics, coding in Swiftswap, running A/B tests, and analyzing implemented changes. After every sprint, we received detailed explanations of the results. These meetings gave us a clearer understanding of our visitors’ behavior.

What was the team composition?

We had a team leader, a conversion rate optimizer, a web analyst, web developers, and a graphic designer. Our point of contact was the team leader.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

We achieved a 22% increase in revenue because of the boosted conversion rate and average order value. 

How effective was the workflow between your team and theirs?

It was effective. We scheduled video conferences with the team lead whenever we wanted, and scheduled status calls after every sprint. We spent seven hours on every optimization sprint, whether through calls, design feedback, or prototype confirmation.

What did you find most impressive about this company?

I was particularly impressed with Growcode because they changed the front end of our e-commerce store without engaging our developers. They used their own technology and talent. Their speed is also worth mentioning. It only took three and a half months to conduct two huge optimization cycles.

Are there any areas for improvement?

It would be great if they worked with small online shops. Right now, they require at least 1,500 orders a month.
