In writing the book, "The Million-Dollar Idea in Everyone," we interviewed several people just like yourself who started a web site with a product to sell. Many found, however, that just setting up the site isn`t enough. You need to build a community so people will come to your site repeatedly--see what else you`re selling and stay interested in not only your products but your point of view. They become experts on the products and on the subject matter pertaining to your product.
You don`t have to take this approach. But doing so makes it a lot easier to get repeat business AND publicity! Take your colorful children`s clothes, for example. You could add "content" (basically your opinion) on why color is important to kids. Or perhaps you want to talk about play clothes, or play groups, or all aspects of play for children. Suppose you take the approach that color makes kids happy. As another person suggested, you could write a blog on things pertaining to kids and color. You might start out talking about your products, but also about taking your kids to the color exhibit at the museum, about how the spring colors are the inspiration for you new spring line, or how an easter egg hunt gave you the idea for a new line of turqouise rompers, etc.
When you launch the new line of rompers, you have an instant audience of people to notify of upcoming products.
You can also pitch stories to the media about your color expertise in terms of children`s clothing and children`s activities. When they are doing a story, they just might call you to be the expert on similar subjects.
Here are some great examples of people featured in the book mentioned above that are using content to create wonderful (and profitable) communities:
www.snowboardsecrets.com - they sell snowboard gear but they "talk" about snowboarding for people who want to make it down the mountain without ending up in the emergency room.
I could go on...
Good luck!
