RSS stands for "Really Simple Syndication" and enables you to automatically include the latest news from another site on your own.

If you sell electronic components then why not add an RSS feed from a news website devoted to your industry? Visitors to your site will be able to get the latest news without going elsewhere. Sports scores? Stock market prices?

How about weather forecasts? Earthquake reports? Public holidays? Any information that may be useful to your customers can be easily collected and made available on your site.
