One of the best ways to keep track of sites that are updated frequently, such as news sites or blogs, is by subscribing to the RSS feed of the site, using an RSS reader, for instance, Feedly or Netvibes. RSS readers allow you to receive new content from all of the sites you are interested in, as it is published, all in one place.
The following services are also invaluable web monitors:
- Google alerts http://www.google.co.uk/alerts?hl=en Sends a daily email of news picked up on subjects you specify—be fairly specific in your search terms to get the most out of it.
- Google Scholar alerts http://scholar.google.co.uk/ Google’s academic search engine alerts service.
- Watch That Page http://www.watchthatpage.com/ Sends a daily email listing any changes to web pages you specify—especially useful for monitoring sites with no RSS feed.
