      Digital Services Review from Brianna Porter

      SmartSites impressed me from day one. They are knowledgable, kind, and most importantly keep things simple and streamlined so that even an SEO-newb like me can understand. Tiffany and Luna are my main points of contact and they are especially great! I would recommend to anyone looking for an agency to really take their website and digital presence to the next level.

      PPC Review from Jim Curry

      At first, a survey was conducted to gather company background, product information, target markets, etc. Next, accounts were established on various Google Business platforms, social media, etc. Then SmartSites created the ads and campaigns, and we were off and running in just a few weeks.

      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)

      PPC Review from Viet Nguyen

      We've had a very positive experience working with HK Digital as our paid media partner. As an ecommerce business focused on sustainable growth and performance accountability, we value partners who combine strategic thinking with reliable execution and HK Digital has delivered on both.From the start, the team demonstrated strong organisation, clear communication, and a collaborative mindset. They took the time to understand our business goals, customer acquisition challenges, and revenue targets, then translated those into structured paid media strategies across our core channels.One of the biggest strengths of HK Digital is their ability to balance performance optimisation with long-term growth thinking. Reporting is clear, actionable, and focused on outcomes that matter to the business not just channel metrics. The team is proactive in identifying opportunities, testing new ideas, and refining campaigns based on data.Since working together, paid media has remained a major contributor to our ecommerce revenue, with campaigns consistently driving qualified traffic, supporting customer acquisition, and helping us scale efficiently. Their responsiveness and willingness to adapt quickly to business needs have made them feel like an extension of our internal team rather than an external agency.Compared to other agencies we've worked with, HK Digital stands out for professionalism, reliability, and a genuinely collaborative approach. They are solutions-oriented, dependable, and focused on delivering measurable impact.I would confidently recommend Travis and HK Digital to any ecommerce brand looking for a performance marketing partner that understands both the commercial realities of running a business and the technical execution required to grow it.

      Performance Marketing Review from Carol Shih

      We've partnered with HK Digital as a performance marketing partner and have referred business back and forth with full confidence. Travis Herndon is extremely knowledgeable, direct, and efficient the kind of partner who doesn't waste time, overpromise, or hide behind buzzwords.His customer service and response time are excellent, communication is clear and matter-of-fact, and most importantly, the results speak for themselves. Travis approaches performance with discipline and accountability, which is exactly what serious brands need.If you're looking for a straightforward, high-integrity performance partner who delivers without the noise, HK Digital is a strong choice.

      Web Design Review from Michael John Norton

      Working with MultiQOS was a pure pleasure. They were timely, efficient but also kind and patient, particularly when I could not come back to them on comments during the working day. Despite this, the project from the outset was treated with professionalism and for that I have a website that I am now very proud of. Thank you MultiQoS. Would recommend to anyone who wants to design their own website!

      I worked at this company for 4 years. Overall, it was a valuable experience where I had the opportunity to grow my technical skills and work with a supportive team. The work environment was collaborative, and there were good learning opportunities.It’s a good place for professionals who are eager to learn and gain hands-on experience in a fast-paced environment.

      Sameer Qurban's Review Sourced from Google

      Extremely disappointed with MultiQoS. Waited over 18 days for an estimation, which I never received. And their response was nonexistent. The communication was lacking and unhelpful. Disappointed with the overall service and professionalism. Lack of service and communication raises serious concerns about their reliability. Not a recommended choice.
