RSS has become the major way to notify readers about recent updates. It has almost replaced traditional e-mail newsletters and other subscription-based methods due to its effectiveness and ease to use. RSS feeds, however, still need subscribers, so submitting an RSS feed to various RSS directories and search engines should be the vital part of any promotion campaign.
Press releases—also known as news releases—are brief, printed statements that outline the major facts of a news story in journalistic style. As part of its overall public relations effort, a small business may need to prepare press releases in order to disseminate new information about its products, services, operations, or other activities.
