      SEO Review from Jay Erdos

      Titan Growth has helped us grow our business by getting us new customers through SEO and Paid Media (Google, Facebook, Instagram, Yelp, and LinkedIn). We just had our best month ever up 110% YOY from their efforts. Our old agency was good, but these guys are great. The TitanBOT technology is impressive. We had a new employee come to us from a competitor and tell us that our competitor had an emergency meeting to figure out how to stop us from taking so much business from them. Titan is great!

      Over the past few years, we have been working with WebFX on various ongoing projects surrounding our websites. They have taken our SEO from non-existent to one of the best websites throughout our time working together. They provide easy-to-understand, solutions-oriented objectives for us and can work cohesively with us to achieve those goals. I like their ability to work hand-in-hand with you and keep you informed in such an organized manner with progress reports.

      Dillon has been amazing to work with. Flexibility is great for agencies, and that is what he offers. We get to work hand in hand with Dillon personally to go over our account's growth and health. He does meetings during times that work best for us as well, and is very good at communication.

      Been using them for nearly 5 years. As a UK based seller I've found them to be an efficient and responsive 3PL. Zack is worthy of special mention - his understanding of the mechanics of FBA, his efficiency and can-do attitude has made working with Marketplace Valet a pleasure.

      Horrible experience ordering 5.11 tactical pants through Amazon. The pants took more than a month to finally find out the delivery service used Canada post. When they were already on strike. They just blamed Canada Post instead of looking in the mirror. Amazon was amazing and issued a refund immediately. Will never deal with these guys again so be leary of these people. And I see they are still blaming Canada Post. Maybe they should be more in touch with National happenings in Canada!
