A blog is a basic discussion or simply informational web site published over the Internet, consisting mainly of informal, frequently personalized blog-style text posts. Blogs are not designed for any particular purpose and are often used by individuals as platforms to express their opinions, knowledge, and experiences. Blogs can be informal, technical, entertainment, academic, or commercial, using any or a combination of these tools. Posts are usually displayed in reverse chronological order, which means that the latest post appears at the top, followed by older posts. In addition, blogs may be categorized by tags, which allows users to easily search for specific subjects.
A blog can make money through advertising or sponsored links. Many blogs also contain advertisements placed within and alongside posts. Some websites provide a mechanism by which a blogger’s in a given topic can leave endorsements that would increase the popularity of that blog, thus attracting more advertisers. Bloggers can make money from blogs not only through advertising revenue but also through sponsored links.
Blogging was once considered a hobby by some, but today it has become one of the most popular forms of communication on the Internet. Blogs can be written by virtually anybody who has basic computer skills, and many people with little or no formal training have learned how to blog and create a profitable web page by adding a few blog posts every week. There are blog software programs that can help make the creation of blogs automated, while blogger templates and plug-ins allow even novice computer users to build their own blogs without any special training.
