eCommerce Development Review from Kate Auchenbach
Over the past few years, we have been working with WebFX on various ongoing projects surrounding our websites. They have taken our SEO from non-existent to one of the best websites throughout our time working together. They provide easy-to-understand, solutions-oriented objectives for us and can work cohesively with us to achieve those goals. I like their ability to work hand-in-hand with you and keep you informed in such an organized manner with progress reports.

Digital Marketing Review from Michael Fratangelo
We had a great experience with Pearl Lemon. Our account manager, Dimple was quick to respond to my enquiry and provide a quote and timeframe for delivery of HTML coded emails. The price was really reasonable and they actually delivered the template ahead of schedule! We also had some feedback on the final product which they rectified promptly and free of charge.

Clint Proudfoot Review from Google

Clint Proudfoot's Review Sourced from Google
I have worked with Dan for a while with my website and SEO. He has written blogs, etc, and done other things for my site. Which has all been fantastic work. The best thing he has done was when my google profile was disabled and I could not fix it. I asked Dan for help, and within 3 days he had got my profile back and my reviews. Great service I would recommend him.
Timothy Johnson Review from Google

Timothy Johnson's Review Sourced from Google
After speaking with Dan, I realized I knew next to nothing about SEO. Dan talked slowly and with purpose and examples as to how improving my SEO and the way I presented my website would help with traffic to my website. I needed it to be simple and Dan has kept it that way.I have to say, Dan was very true to his word. He audited my website, of which I am still going through and implementing. The traffic has increased, the inquiries have increased and I am now having more contact with clients than ever.Appreciate the help and the guidance Dan, great work sir.
