Real money will only come if you have real products. By real products we mean goo and high quality products. You can only establish sales and attract more customers if you are able to provide them good products. It is important that you should not only provide quality for main products but also for the up sell products. Customers will not upsell their purchase if the main products itself are not of good quality, and if you are offering low quality upsell products, customers may choose not to upsell at all. If you want to stay on the top, do not compromise the quality of your proucts because that is the only key for you to generate more sales.
