Do plenty of research into eCommerce software before picking one. There are plenty of options available ranging from simple (for small web stores with few products) to complex (including accounts integration and stock checking).

 
 
 Thank you all... I am planning on doing Magento community. i'm actually a graphic designer by profession, so it won't be too hard for me to manage my content and products. I do plan on having a super active blog attached to the website. Blogging is tedious work, but it has made all the difference for my graphic design sites.
 
 
Hey Mili, good that you came up with this topic... an eye opener for more people like you and me. One more hint i can give is attend Business networking place... you may have potential customers there looking for your products.  
 
 Hi, I have been in eCommerce since 1995 with multiple stores. All the experts will tell you how to drive traffic to your store so I will not comment on that. Most of the experts will not tell you what to do with them once they get to the store. You have shopped before and know if it is easy to buy what you want, the sales people are friendly, helpful and not pushy and the store sends you promotions for being a good customer you will go back. In eCommerce content and navigation is king. Amazon is too large to copy but it is very easy to do business with them. If you have multiple products or services and the experts have shown you how to drive traffic to your site by product or service, they should land on that page not the home page. With less than four clicks they should be able to check out and pay. Once you have sold some one capture their email address and thank them and do not try and sell them with the thank you email. Give them the opportunity to opt out of future notifications at that point. Most wont. Remember the easiest customer to sell is your existing customer. Poor navigation will kill your business. Make it simple, selling and straight forward. Ask some specific questions and I will help you out. Remember this. All the SEO and SNM are great but converting visitors to buyers is more important by far. I got a 4.5 percent click through rate and a 8.5% visitor buyer rate selling women's high fashion jeans and blazers. Those two numbers are by far the most important in your business. I only got one return in three years of doing business.
