Epidemic Marketing Reviews & Testimonials

SEO Review from Kealy McCormack
Epidemic Marketing knows a ton about SEO and helped get our website seen online! They were great at responding to our questions and continuing to hone in SEO on our website for years. Overall, the cost and wanting to move in house in order to have more control over the website is why we left but if anyone needs SEO help in Denver they are a great option!

SEO Review from Tim Cardona
Noah and his team have been so amazing for my automotive detailing business. I didn’t understand SEO at all but I knew I needed it to grow my business. When I first talked to Noah he wasn’t pushy on selling me anything. Just simply broke everything down for me to understand and made it work for me. He has helped my business stay competitive and on target with SEO and my website! I can’t thank Epidemic Marketing enough it has been over 2 years now I have been with them and I’m glad!!

CRO Review from Brian Hong
Noah is a wealth of information and someone I have the pleasure of working with. He provides extremely actionable insights with conversion rate optimization, as well as advanced SEO techniques that move the needle.We have worked on several CRO campaigns that helped turn more visitors into customers which made our dollar work harder for us and Paid Media campaigns. He’s a true pro and even better human.

Mobile App Development Review from Lee Tupper
Vention has delivered excellent design prototypes and accurate time estimates. The app is still in beta mode, and the partnership with [...] Vention will [continue] until the release of the next version. Vention is a reliable team that offers quality service. (Verified via email)

Staff Augmentation Review from Jon Wade
Vention’s efforts allowed the successful development of the product, resulting in new customers. They provided backend developers, business analysts, UI designers, and QA testers to develop our solution. Vention cultivated a seamless partnership through constant updates and a collaborative approach. Overall, their team’s well-rounded expertise was impressive.

Web Development Review from AJ Canty
We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

DK and the Clap Creative crew are just amazing. The responsiveness and turnaround are unimaginably fast. We have been with them for about a year or so now and they have made everything so simple for us. If you are looking for a solid company to help with your site maintenance, this is the one to go with!
Stephanie Yee's Review Sourced from Google
Had the pleasure of working with DK at Clap Creative. We were very pleased with his responsiveness and ability to meet our requirements. We were very satisfied with his work and wish we discovered Clap Creative a long time ago to help us out. Highly skilled team, great service and affordable prices! We highly recommend Clap Creative and hope we can continue to work together.
Jennifer Sorcher's Review Sourced from Google
I have had such an amazing experience while working with Clap Creative! DK has been helping us for a while now, and he has built our site so beautifully! Not only is he quick to answer and eager to get the job done, but he is also informative and respectful as well! You can tell that DK and his team know what they're doing, and I would recommend them to anyone and everyone! Whenever we have a small site glitch or SEO issue, they fix it within the hour! A very much needed quality in any web team! To sum it up, Clap Creative is one of the best web teams I have ever worked with!
