Internet portal Yahoo! on Sept. 23 enhanced its shopping section to include a comparison-shopping function. Yahoo! Product Search uses algorithmic search technology to extract results from multiple sources, including Yahoo!’s database of more than 17,000 merchants, a new database of merchants that have established direct feeds into via Yahoo!’s new Product Submit program, and merchants and products identified through crawling capabilities.
The technology allows for a side-by-side price and feature comparison that enables consumers to compare up to 10 products at a time. It also gives consumers the ability to rate merchants or products.
