      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.

    • Helen Guzenko
      Helen Guzenko Partnership Manager at Wezom
      5.0★

      Startup Review from Helen Guzenko

      Wezom is an enterprise software development company with more than 275 specialists. We brought RGray in for startup marketing and growth marketing for a FinTech SaaS platform we had built for a client, an early stage startup with a finished product and almost no market presence. RGray started with their startup marketing foundation: market and competitor research, positioning and messaging, and a growth strategy built on three prioritized hypotheses, each with its own funnel and success metrics. They then implemented the channels: SEO, GEO for visibility inside AI search and AI assistants, PR and digital media, and paid user acquisition to test the funnels fast. Analytics and attribution were in place from the start.They also built AI into the daily marketing work: a custom multi agent system using Claude, Grok, Perplexity and Gemini for research, content production and localization, handed over with workflows, prompts and checklists. Two of the three hypotheses proved out, so we elaborated those two and their funnels. CAC started at $31 and fell to $16 by the end of the test campaign, below the industry average. The campaign brought around 2,500 activated users, which boosted revenue and gave us real data for funnel, user and product analysis. The client finished with a working acquisition system and the documentation to run it, not a set of campaigns. Project management was on time and on budget: weekly calls, a shared board with owners and deadlines, monthly reporting against the strategy metrics, same day answers. When our client's roadmap moved, they resequenced the plan in days. Most impressive: they think like product owners, not like a service agency, and they challenged our ICP and pricing assumptions correctly. One improvement: the early reports were denser than we needed, and they added an executive summary once we asked.

      Outcome = awesome and unique yet simple logo that I love. Process = Sean really understood what I was after, helped me articulate it better, he was creative with good ideas/suggestions along the way, and we did multiple rounds of revisions/tweaks until it was just what I was after.

      Sean recently presented on SEO to an entrepreneurial group which I am a part of. He took a concept that can be rather confusing and translated it into an easily digestible format. He clearly answered all of our questions and gave us several actionable items that we could immediately take, to improve our website SEO. I’m very grateful his assistance!
