Codedesign Reviews & Testimonials
Lucy Saint-Antonin Director of Communications & Marketing at TLScontact
5.0★
Digital Marketing Review from Lucy Saint-Antonin
I really enjoyed working with the Codedesign team. They have a very methodical approach, first analysing and understanding business needs and then proposing the most appropriate strategy to meet those needs. They were very responsive throughout the digital project that we worked on with them, and demonstrated strong expertise on topics such as Google and Meta ads, and SEO strategy, helping us to increase traffic and conversions. I wouldn't hesitate to recommend them for any project requiring digital marketing expertise.
Rita Corrêa Mendes CEO at Grupo Hug
4.7★
Digital Marketing Review from Rita Corrêa Mendes
I chose to work with Code Design on the launch of Grupo Hug because I believe they possess essential characteristics that are extremely important to me in a digital agency: team qualitification, digital expertise, credibility, client results orientation, a holistic digital approach always with an interest in going beyond a simple objectives briefing. They are very responsive and collaborative, and we have a fluid and transparent communication. They are available, always seeking to meet our needs reactively but also proactively.

Email Marketing Review from Ramin Schultz
JP was a huge help in creating eye-catching designs for my email campaigns. He understood exactly what I needed and delivered polished, professional visuals that really boosted the overall look of my emails.

Jordan Lingohr Director at SocialMate

Email Marketing Review from Jordan Lingohr
JP and he team at EcommerceBoost are such a breath of fresh air. We've wasted an ungodly amount of time, money and every into looking for a reputable email marketing agency for our e-commerce brands, but once we had the kick-off call with JP, we knew we'd found the right (and last) email marketing agency. That was a few years ago -- working with EcommerceBoost was one of the best choices/hires we've made in a while.
Luciano Viterale Growth Marketer at Ticker Nerd
5.0★
CRM Emailing Review from Luciano Viterale
JP and the team at Ecommerce Boost have been incredibly helpful. Not only did they map out our email funnels and help us convert more subscribers into paying customers they generated ideas for the copy and guided us throughout the process. They made it clear which strategy to follow, why it would work, and the results to expect. They were spot on and these sequences still drive revenue for our business! Thanks JP and team!

Dan Ferguson President at Communiti Labs
5.0★
SEO Review from Dan Ferguson
For our social media marketing, we have been collaborating with SEO Discovery, and the experience has been excellent. They made the impact right away by taking the time to learn about our audience, our objectives, and our brand. Their designs are consistent with their brand, their communication is consistently professional and timely, and their content approach is well-considered. Better reach across platforms, a more consistent online brand presence, and a discernible rise in interaction have all been observed. The fact that they don't provide a one-size-fits-all strategy and that everything feels customized for our company is what I value most. I heartily endorse SEO Discovery. Our company has benefited greatly from SEO Discovery SEO services. We were not very visible on the internet before. We've noticed a notable rise in organic traffic and leads since working with them. Their methodical approach and persistent work have paid off handsomely. Whole group are competent, professional, and produce measurable outcomes. For efficient SEO, we heartily endorse SEO Discovery!
Laurient Salimpour President at WILSON PLAZA GROUP

SEO Review from Laurient Salimpour
Damans were quite useful to make the entire process smooth and pleasant in terms of answerability, technical expertise, and problem solving issues. They explain themselves as you can see and with people as leaders like Daman you are in good hands. We engaged SEO Discovery on the development of official website of SUN Can Immigration and the outcome was great! Whether you look at the design or at how the site performs, everything demonstrates an in-depth knowledge of who we are and what our clients need. And a special thanks to Daman, the Project Head who was an absolute coordinator, strategist, and dedicated to deliver every milestone perfectly well. He is extremely capable of transforming our vision into a Chrome-like user-friendly conversion-driven site. The whole process was so easy and enjoyable thanks to the responsiveness, technical expertise and solution focus of Damans team. The SEO Discovery team not only produced a professional and visually powerful site but ensured that it was completely seo-based, fast and mobile friendly laying down a robust platform upon which we will build on our online presence. Their output is self explanatory and you can very well be assured that you are safe in the hands of the likes of Daman.
Ankur Chimra Founder at Sun CAN Immigration

Startup Review from Ankur Chimra
We worked with SEO Discovery for the development of our official website for SUN Can Immigration, and the results were outstanding! From design to functionality, every aspect of the site reflects a deep understanding of both our brand and the needs of our clients.A special shoutout to Daman, the Project Head, whose exceptional coordination, insight, and dedication ensured that every milestone was met with precision. His ability to translate our vision into a clean, user-friendly, and conversion-optimized website was remarkable. Damans responsiveness, technical know-how, and solution-driven approach made the entire journey seamless and enjoyable.The SEO Discovery team not only delivered a professional and aesthetically strong website but also ensured it was fully aligned with best practices in SEO, speed, and mobile responsivenesslaying a strong foundation for our digital growth.If you're looking for a web development partner who delivers on time, communicates clearly, and goes above and beyond, I highly recommend SEO Discovery. Their work speaks for itselfand with leaders like Daman at the helm, youre definitely in good hands.

Sara Busseto's Review Sourced from Google
Recommended! They delivered outstanding results. In less than a year, they helped achieve 10x more first-page Google rankings for relevant keywords. After previous experiences with other SEO agencies that failed to deliver similar results, their strategy made a measurable difference. Beyond increasing online visibility, they supported lead generation and provided valuable marketing resources to improve conversions. Their expertise, creativity, and commitment clearly set them apart.
