      eCommerce Development Review from Noah Austin

      OkCapsule notes that it's rare to find a team like Sunrise Integration that combines technical expertise with exceptional people skills. Its mix of intelligence and charm was appreciated throughout the partnership. The objective was to transition the infrastructure of a custom e-commerce application to support headless commerce across different platforms. Impressively, Sunrise Integration completed the job below the estimated budget and faster than anticipated. (Verified via email)

      Web Design Review from Max Golovan

      We hired Traffic Dojo for our website, SEO, and social media marketing. They designed, developed, configured and launched a new website for us. The project began with understanding requirements, doing wireframes and prototyping. Once we approved the workflows, wireframes, and mockups, the actual work began from their side. In couple of weeks a functional version was ready with dummy content for user testing. Improvements were made as per our guidelines and responsiveness were tested along side the testing. Final version of site was made live in another 2-3 weeks time after our approval. SEO work was started and mapped every month.

      Digital Marketing Review from Austin Arthur

      We hired Traffic Dojo to help with SEO services and manage our Google ads efficiently, Our main goals were to make our website visible and help achieve our business marketing goals as well. We took the help of Traffic Dojo to get experts on board who can help us with our ultimate goal. With their help, we were able to make our website appear higher in SERPs organically. We ran Google Ads to promote some of our services, but the rest of the website was optimized to rank organically. They used a lot of methods and it took time, but in the end, it worked. Traffic Dojo gave us a timeline and they delivered within that.

      Web Design Review from Rae Felte

      Traffic Dojo built our website from scratch using Craft. When I first talked to them, We spent almost an hour talking, and they answered my questions. I knew what I wanted, but I didn't know how to get there, so Traffic Dojo told me what they thought. After our first conversation, they made a proposal and mailed it to me. They walked me through the project and what to expect. Then, they put together a platform and sent it for review. The website was an information page and also, users could contact us through email to send information. Traffic Dojo knew what they were doing. They listened to what we wanted and made it work. Overall, they were good at their job, and we made an excellent team.

      Web Development Review from Griffin Joliboix

      The team at Genetech did a great job helping us get our website back on track when updates were pushed through that we were unaware of. These updates caused implications that were problematic to our website performance at the most crucial time of the year for our sales, and their timely work helped out tremendously.
