Domain name does play a role to help people remember the site, but it has got very little to do with the sites popularity or business. Its better if the domain name is related to the theme of the site. Try to use names which are simple to spell and easy to remember.
Bad server can cause problem for the uptime of the website or the speed of its download. It surely won’t prevent visitors from your site or online sales taking place. Today most site hosting companies provide good web servers at a reasonable rate.
Well the design of a website has got very little to do with the traffic it can generate or the volume of business it can provide, as long as it is well structured, has a good navigation and quality content. The colors and images make very little difference. But remember the product photos should be of great quality and in good visible size.
Ok. Then whats wrong why is there no sales ?
A website generates sale due to some essential factors:
a) good content,
b) steady traffic,
c) product to match ones need
d) usability of the site
Write high info-value keyword focused content that ranks well with the search engines. Have a PRE-Selling content (not a sales pitch) that establishes confidence and trust and influences the visitors into becoming customers. The content should be honest and try to take the visitors into a ready-to-buy frame of mind and turn them into lifelong customers. Proper content management is important before you drive traffic into your site else your visitors won’t be convinced to buy.
