Digital Marketing Review from Brian Grubbs
As the owner of E&B Carpet Cleaning, I can confidently say that partnering with Seafoam Marketing has been one of the best business decisions we've made in our company's history. Over the past decade, they've transformed our digital presence and helped us achieve growth that we never thought possible in our competitive market.What truly sets Seafoam apart is their deep understanding of both digital marketing and the local service industry. They didn't just implement generic marketing strategies they took the time to understand our business, our customers, and our goals. Their team developed customized campaigns that specifically targeted our ideal customers, resulting in higher quality leads and better conversion rates.The impact on our business has been remarkable. Since working with Seafoam, we've seen consistent year-over-year growth in both website traffic and customer acquisition. Their SEO expertise has helped us dominate local search results, while their content marketing strategies have established us as the go-to authority for carpet cleaning services in our area.What I appreciate most about Seafoam is their transparency and commitment to results. They provide detailed monthly reports that clearly show the ROI of our marketing investment. Their team is always accessible, responsive, and proactive in suggesting new ways to improve our marketing performance.For any service-based business looking to grow their digital presence and generate more qualified leads, I wholeheartedly recommend Seafoam Marketing. Their expertise, dedication, and proven track record of success make them an invaluable partner for long-term growth. After more than ten years of partnership, I can say with certainty that Seafoam Marketing doesn't just meet expectations they consistently exceed them.

When it comes to technology I'm certainly in need of expert assistance. Last week I had a huge scare! I accidentally deleted ALL of my web-based courses off of my business site. It happened late at night and in my panic I called my Seafoam expert, Ryan Foizey. I was surprised when he answered! He not only answered, he worked on it that night and by early the next morning I was back online with everything back. I can't tell you how much I appreciated it and how that saved my business! It absolutely was above and beyond and sure gained my Seafoam loyalty. Thank you to Ryan, Nikki and the rest of the team for your excellent customer service!

David Dafoe's Review Sourced from Google
We found UPBrand as we transitioned from a company that didn't meet our expectations as our company grew and expanded. Their initial pitch was impressive and after a great deal of research and pitches from other organizations, we chose UPBrand and have never looked back. They continue to exceed our expectations.

My experience with UpBrand Collaborative has been very positive. Their team jumped in to quickly digest our complex go-to-market strategy and effectively translated consumer and dealer insights into an actionable plan. Their creative team brought the new brand to life with a dynamic new logo and supporting design elements. We are thrilled with the results and look forward to working with UpBrand again!
