HigherVisibility Reviews & Testimonials
Michael Brumleve CEO at Brumleve Industries
5.0★
SEO Review from Michael Brumleve
We have used HigherVisibility now going on 3 years. Our SEO rankings and eCommerce sales have been fantastic over that time span. More than I could [have] anticipated. This team knows what they are doing in the complex SEO and PPC world and are a huge asset to us. 3 years ago, we had basically 0 online presence. Now, we are consistently ranking #1 on Google for our best-selling products. (Verified via email)

Skippers Seafood Review from Google

Skippers Seafood's Review Sourced from Google
Started working with ZGM a few years ago to boost my local foot traffic. I had SEO and PPC going at first but added an email campaign to focus on returning users and saw tremendous ROI. The team is exceptional, Chris Uzzo is so kind and transparent, and it helps that the agency is always so prompt with responses.I will continue to support this marketing agency and anyone looking for digital marketing, needs to reach out...NOW!

We have been working with Zero Gravity for several months now and cannot recommend them enough! Their support, suggestions and knowledge have helped immensely. Not only are we continually impressed by their skills but they are the friendliest and most approachable group I've got to work with.
Ryan Review from Google
5.0★
Ryan's Review Sourced from Google
As a relatively new company (almost two years established), we were at a loss for our marketing efforts. No matter what competitors did, we were always outmatched and outranked. I went to ZGM to help solidify a strong SEO strategy while boosting our paid campaigns by targeting competitors. I was amazed at how much I didn’t know and the results spoke for themselves. I couldn’t be happier to have hired their agency and would highly recommend anyone to invest in their digital marketing strategy. Since I’m in a competitive software industry, I thought it’d be impossible to rank but zgm helped get me higher in the search engines and our lead gen is skyrocketing
