A blog is basically a very simple website used for sharing news, information and opinions. There are two important and exciting things about blogs (which is why they are causing such a stir):
- They are crawled and indexed by search engines; viewed as 'news' blogs can do quite well when it comes to search result rankings, making them a useful (and often free) marketing tool.
- Because they are websites, links from a blog can improve the page rank of another website, making them useful (and often free) marketing tools (are you seeing a theme?).
