  Can’t say enough good things. I initially hired 1Digital to handle the SEO for my online brand. They did such a good job I ended up offloading all my marketing initiatives over to them. My biggest complaint with previous agencies is that I always felt like I was driving the ship and the company I hired was just doing what I said. With 1Digital they take command of the strategy and think bigger than I ever could. They come to our meetings prepared and it truly feels like they are thinking about my business rather than just emailing me reports. Give them a call, you won’t be disappointed.
  – Jeffrey Reddick

  Great experience working with 1Digital. We contracted them for an end to end e-commerce site build with ongoing SEO blog campaigns. The team took on our project after a series of focused kick-off and scoping calls, and rapidly delivered a great site for us. They kept us in the loop with bi-weekly updates along the way, and gave us many opportunities for input. Overall, very happy with the process. Money well spent.

• Specializations: Ecommerce SEO, PPC, social media marketing, and conversion optimization.
• Why Choose Them: Known for their customized strategies and results-driven approach, 180 Marketing helps businesses stand out in competitive markets.
• Customer/Client Reviews & Testimonials:
  

  I decided to seek SEO help when after listening to a podcast that pointed out how many E-Com companies will spend a fortune on PPC because of the immediate return, but are reluctant to invest in SEO because it can take a long long time to see results. We had been seeing a slow, but steady decline in organic traffic and I wanted to see if we could turn that around.

  We did. In the short time that I’ve been working with Jeff our organic traffic is up 49% YOY. We’re ranking on the first page (many keywords are in the #1 or #2 spot) for keywords that I never even thought we should try to rank for because they’re so competitive.
  – Brett Haney, President, Microfiber Wholesale

  180 Marketing has been a very valuable asset with our company in the last 18 months. They not only helped our company get positive results from SEO almost immediately, they also helped us with a lot of bad links and old SEO techniques that were making us rank lower. 180 Marketing has always been very helpful and goes the extra mile for us. But, most importantly, we trust 180 Marketing thoroughly with their advice and the handling of our SEO efforts explicitly. After being taken advantage of with a former vendor previously, 180 Marketing was exactly what we needed…an experienced and trustworthy SEO company.
