RSS feed items will not enable much better ranking as their content is syndicated and therefore not unique. However, the increase in traffic that is generated as a result of your site being the place to go for information will help your SEO. The more time a user spends at your site, the higher it will rank too. Google keeps a track of all these metrics and uses them to keep track of your site and how much it appeals to the people who visit.
RSS is a type of web feed which allows users and applications to access updates to websites in a standardized, computer-readable format. These feeds can, for example, allow a user to keep track of many different websites in a single news aggregator.
