If you can direct your marketing efforts more precisely to that group,  
this is niche marketing - the process of identifying a group of users of 
your product so the better the identification of your target buyer group 
then the more efficient your internet marketing and the better the sales. 

It's better for web design to single out the key benefits rather than 
overloading the customer with a long list of features.

You may have developed a unique online shop, but why do you believe your 
web design idea will be successful? 

Your idea must fulfill a need for your buyers and must do it in a way 
that's better than the competition.

Do you know who your buyers are? Do you know why they buy products through 
your online shop?  Try to establish niche marketing in an area that seems 
to be under serviced - one in which there's not a lot of competition - then 
do some internet marketing research to determine if it looks like a viable 
market. 

How can you segment the market?  Find out more about your customers by doing 
market research: 
number, timing and brands of purchases made
reasons for purchases 
consumer attitudes about various product attributes 
importance of the product to the lifestyle of consumer 
demographic information

Uniqueness, which helps you stand out from the crowd.
