What are the limitations of internet marketing?

Limitations of internet marketing:
1. One of the challenges that Internet marketers face (as does the general public) is that many internet products are outright scams or promoted with deception making it difficult to know which one is worth buying. This is especially the case with products that are supposed to train or aid Internet marketers in making money. While the quality of products has improved in the past few years, ethics are often still missing in online marketing. Many so-called money making products are “empty boxes” in which there is essentially nothing there, yet a buyer is to make money by reselling this empty box to others. Pyramid schemes are also still prevalent.
2. The consumer is unable to physically feel or try on the product which can be a limitation for certain goods. However a survey of consumers of cosmetics products shows that email marketing can be used to interest a consumer in visiting a store to try a product or to speak with sales representatives; from here a purchase decision can be made.
3. The marketer will not be able to use personal interaction to influence the audience as the marketing is completely based on the advertisement and the information that the advertisement might lead to (websites, blogs and other channels).
