We had used other SEO companies with mixed results, but none of them delivered what they had promised. When we contacted Carl Doppler at Doppler Internet, we liked the way he managed our expectations, and were impressed with their professionalism. We gave him the contract, and they have way exceeded what we were hoping for. They outperformed the other companies, and will be our sole SEO provider from now on. Josef Davids, Sanford, FL.
