SunTec India Reviews & Testimonials
Joe Di Lucci
eStore Manager at Ranger Plumbings
5.0★
Shopify Review from Joe Di Lucci
The ideal solution provider for every eCommerce store setup and optimization issues.
We wanted our new Shopify store to get great brand visibility and conversions but lacked the resources and expertise for it. Partnering with SunTec India gave us access to experts who competently assessed our problems, solving them with creative product descriptions, SEO strategy generation, and product data entry service, bringing us on par with our competition.
Walter Venkel
Sales Executive at Firmwrap Gifts
5.0★
Amazon Review from Walter Venkel
Excellent Amazon eStore product listing and advertising support that skyrocketed our sales.
Our corporate gifting eCommerce startup faced the problem of poor brand visibility on Amazon. We partnered with SunTec India to handle the problem and were delighted with the results. They sorted our products and listed them accordingly while optimizing our PPC campaign to give better ROI. They're now our permanent partner for the job.
Randy Linker
Manager-Digital Marketing at Bergman Holdings
5.0★
Web Development Review from Randy Linker
The web development partner that can give bespoke websites within a tight schedule and budget.
Our company deals with supplying industrial equipment procured from many manufacturers to clients of various industries. We had not been doing this well due to the lack of traffic-generating capabilities of our incumbent website. SunTec India fixed its content and SEO issues, making it more appealing to our target group. We've now become standout suppliers in our industry; thanks to SunTec India.

Our communications department participated in a 3-day training course on natural referencing provided by Eskimoz. These three intense days were a real gold mine in terms of knowledge and actionable strategies for our website. A huge thank you to our trainers Quentin Giraud and Manon Beloin for their expertise and teaching!

SUSO Digital Reviews & Testimonials
Ian Mount
Review from Google
5.0★
Ian Mount's Review Sourced from Google
We had SUSO run an SEO audit for us and came away really impressed. Cara and Filip were both great to work with; clear communicators, responsive, and the audit itself was thorough and genuinely actionable rather than just a list of generic findings. Highly recommend!

Emma McSweeney's Review Sourced from Google
Our experience with SUSO so far has been great. The founder, Will, has personally given his own time to offer training and workshops to our team which was great for us as an agency looking to bolster what we are offering to clients. SUSO has a good approach to doing business with agencies and offers a flexible partner programme which we will continue to explore.

Nicola Rellie's Review Sourced from Google
We recently attended a workshop led by Will from SUSO, and we couldn't be more impressed. Will broke down the basics of SEO in a way that made the complex easy to understand. He also walked us through their partner programme, showing us how SUSO can help us bring even more value to our clients. The way SUSO works with agencies is really flexible, and their dedicated helpdesk support makes us feel confident about teaming up with them for future projects.
