Comparison-shopping website NexTag has launched a service that uses RSS feeds for NexTag search results, providing shoppers with automatic updates of their product or service searches. Users with an RSS reader can access the RSS button on any search results or category page on NexTag.com and generate an automatic RSS feed. When the RSS reader is launched, users receive notification if the search results page has changed - avoiding the need to perform periodic product searches on the site.

NexTag, a privately held company based in San Mateo, California, operates comparison-shopping sites in the U.S. (www.nextag.com) and U.K. (uk.nextag.com).
