      Digital Marketing Review from Randy Hill

      We hired Allegiant Digital Marketing after several failed attempts with other digital marketing agencies to help us generate business from the internet. They helped build our new website and run our PPC and SEO. As soon as we began working with them we noticed instantly a pretty substantial uptick in our digital leads. Not only are they really good at what they do, but they really show they care about our business by going above and beyond for us. Highly recommended!

      Arthur Choi's Review Sourced from Google

      Allegiant Digital Marketing has gone above and beyond for us time and time again—handling complex website migrations, hitting emergency deadlines, and delivering the impossible with incredible skill. So many times, when our company was in a bind, Chad and his team stepped in and saved the day for us. Whether or not that is fixing caching issues, delivering on technical SEO requests, and providing us with an actionable marketing strategy to help our company stand out from the rest of the competition. Chad Markham, the owner, brings vast expertise not just in marketing but also in the M&A space across diverse industries like HVAC, tree care, restoration, roofing, and eCommerce. His team is equally outstanding, especially Chris Tucker (no relation to the celebrity!), who has consistently prioritized our needs even during their busiest times. We’re infinitely grateful for their dedication and highly recommend them to anyone looking for a top-tier marketing partner!

      Gregette Smith's Review Sourced from Google

      We couldn't be more impressed with the exceptional service provided by this digital marketing company. Their team has consistently gone above and beyond to understand our business needs and deliver tailored strategies that drive results. The professionalism, responsiveness, and expertise they bring to the table have been invaluable to our growth. From improving our online presence to generating quality leads, they’ve been an incredible partner every step of the way. The detailed reporting and proactive communication give us confidence in their ability to adapt and optimize our campaigns. We highly recommend them to any business looking for a reliable marketing partner for RHP.

      Jim G's Review Sourced from Google

      As the owner of a commercial construction and maintenance company I have constant communication challenges…getting updates from the field, tracking materials, managing hours. It was eating up way too much time for everyone involved. We brought Epic Apps in to solve that, and they delivered on every front. They built us a custom private tablet app that our field crews use daily to order job materials, log hours, and submit job updates; and an internal website that doubles as an employee feedback hub, which has genuinely improved how we operate as a company. The whole team was professional and responsive from start to finish. If you're in the trades and looking for a development partner who actually gets your industry, Epic Apps is the real deal. I highly recommend them! Jim Gagnon Owner – NorCal Construction & Maintenance Inc.

      Stephen Meader's Review Sourced from Google

      In a year with only 20 hours of effort a month we went from getting an average position of 45 with 1,500 impressions and 8 clicks a day; to an average position of 30 with 10,000 impressions and 18 clicks a day. The implementation of a theme was previously botched by another company and Smile Media was able to come in and work on fixing those issues while still focusing on SEO boosting. Their technical skills are extremely good and they are transparent about their billing with hourly breakdowns. Definitely a good SEO company.
