Price Comparison Sites are sites that help buyers choose the best product with the most reasonable price that they are looking for and shopping sites to help generate more traffic on them.
*Why Cost-Comparison Sites Work?
People tend to prefer to use cost-comparison sites because a lot of their time is saved on these sites than to physically go to stores or search on merchant websites to get a good price of the product they are looking for. Through cost-comparison sites, results are received in just a few minutes.
*Data Collection ways for Best Price Online Shopping
This method of data collection is considered a good one by comparison sites because the data is collected by a software that visits different merchant websites and compares their data on similar products and thus data received is accurate and rich. Though the merchant sites do not display their products in similar ways so it becomes hard for comparison sites to decide if the products identical or not and this method is slow so it is to adopted by many Price Compare for Online Shopping.
*Feeds From Merchant sites
By collecting data feeds, in the from of CSV files, from online stores, comparison engines compare and display their own data by comparing their products. This method is easy to implement by the cost-comparison sites but it is less accurate as the feeds are prepared and made available for comparison sites by merchant sites themselves and they make only the popular products or products that they want to be on the comparison sites and not the rest; making it less rich.
