Driving Digital Marketing Results Since 2006

About Us

In 2006 digital marketing expert and pioneer Justin Seibert founded DOM after seeing an opportunity to effectively help companies grow their businesses online. Named a top 25 most influential PPC expert, he worked diligently for over a decade to build a team of online marketing professionals. Along the way, he has also worked to perfect proprietary Google Ads skills, procedures, and performance requirement benchmarks proven to deliver our customer base the best results. At the core of these best practices is DOM's disciplined approach, complete transparency, straightforward communications and culture of excellence. This is what we call The DOM Difference.

SEM Qualifications

Anyone can say they're experts at online marketing. DOM has the credentials to back it up. We are highly accredited across all major platforms, including being one of the top 200 Premier Google Partner firms in their managed program for digital marketing agencies. DOM is also a Bing Ads Accredited Agency, covering both major pay-per-click search engine ad platforms in the United States. Our influence extends beyond the United States and Premier Partner status, though. From our home in the Greater Pittsburgh, PA-area, we have helped our clients sell into the over 140 international markets we serve. We sit on the WV District Export Council, have been recognized for our exporting achievements by the U.S. Commercial Service, and been awarded as Exporter of the Year by the WV Small Business Administration.

The DOM Difference

Based on years of experience and careful attention to what makes us the most successful for our clients, The DOM Difference™ is a collection of our proprietary best practices to developing digital marketing solutions proven to get the best results. These best practices include a disciplined approach to developing tailored solutions, honest straightforward communications, complete transparency, and a culture centered around excellence.

What does “The DOM Difference” mean for our clients? Before specifically getting into that, we’d like to take a second to talk about our retention rate. Our client retention rate was 85% when we last checked. That means a lot because, for us, it’s one of the most reliable indicators that every team member we have is doing their absolute best for our clients. Seeing the same clients stay with us over the months is gratifying, especially since we don’t ask anybody to sign a long-term contract.

They don’t stick with us for their Google Ads campaigns or SEO strategies because they have to. There are plenty of other Premier Google Partner agencies they could choose to work with.

They stick with us because they want to.

What People Are Saying

Ian Brown testimonial for a Pittsburgh marketing firm

“Working with DOM is like working with colleagues who have our company’s best interest at heart. Our CMO introduced me to them eight years ago, and I have been using them for our digital marketing needs ever since. Their status as a trusted Google-partner is comforting, but we’re loyal to them because the quality of their services is unfailingly effective.”

- Ian Brown, Director of Marketing, Appify
Dan Bernoske testimonial for a Pittsburgh marketing firm

"DOM is a digital marketing firm that consistently delivers quality leads for me and my clients. Their account management team is responsive, they continuously provide insights, and they share innovative new approached to digital marketing. After many years in search of a go-to digital agency, I have found one in DOM. I strongly recommend and promote them to anyone."

Shannon Javetz testimonial for a Pittsburgh marketing firm

"No matter what you’re trying to market, DOM will learn about the product so they can provide the best support. Their responsiveness to the adjustments we need helps us better interpret and improve our conversion numbers. They offer suggestions, but they don't come across like pushy sales pitches, which can often happen with other agencies."

- Shannon Javetz, Associate Director of Advertising, SCAD
