Lack of trust is the main issue why people fear using e-commerce for their regular shopping purpose, whereas e-commerce is very much cost-effective as compared to traditional shopping. But people fear using e-commerce just because there is no personal contact with the vendor. So it is a biggest challenge to remove this fear from the minds of buyers. The only solution to remove this fear is building Trust in their minds. There are many factors which should be focused upon while building this trust; they are broadly classified as knowledge-based trust which includes familiarity, reputation, brand, size and website quality and customer service.
