When you are searching for reseller hosting, there are a few things to keep in mind when choosing your host.
You want to be sure that the company reflects your standards in business. If the company has a lot of down time where servers are offline, it is going to reflect on you when it happens to your customers. Companies with high reputations got that way because of their excellent customer service.
You also want to consider how much customization you can do to your reseller site. If a company only offers a template with your name on the top, you might want to look elsewhere. Customization helps you stand out from the rest of the web hosting companies.
Personal service is something that is going to be important for your long term success. If every last detail is automated, how are you going to connect with your customers? Take the time to get to know them either by email or phone. It will go a long way to keeping them as customers.
