Some are not aware that information is being collected on them and sold to third parties. Others are afraid that merchants knows exactly who they are and can see everything they do on the Internet. Nonetheless, this is an issue that retailers will have to deal with in order to attract online shoppers. Retailers are finding ways to block shopping bots, thus limiting the number of retailers that a consumer can compare. Similarly, the shopping bots do not collect every available and relevant retailer.
Some shopping bots charge retailers to be included.
Secondly, there is no uniformity to how web sites are organized or what information is provided. Consumers will not always find the information they are seeking. Likewise, the Internet is not as developed as the physical shopping world so not all products are available online. Searches can become tedious since one must utilize several different search engines to scour a majority of the Internet. Therefore, comparison shopping can be a difficult task.
