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.

SEO Review from Marty Marion
I never leave reviews, but once in a while the work quality is so good I make exceptions.This is one of those times. Noah provided very advanced SEO work for one of my largest clients, fron scratch, finding and fixing SEO technical issues and conversion optimization issues that made a major difference for my client in both organic traffic and conversions.Traffic from search increased more than expected. Conversions to sales increased by about 20% plus an increase in AOV. Combining both an increase in traffic and an increase in conversions and an increase in AOV is nothing short of a home run.I will be channeling more of my clients' SEO and CRO to Epidemic for sure. Great people to work with, awesome results. And I teach digital marketing professionally.Marty MarionCEOMaster Positioning, LLC
