A blog is essentially a personal, usually informal commentary or informative site published online consisting of usually discrete, sometimes anonymous blog-style text entries. Blogs can be written by anybody and can have any number of readers. They can be maintained by a single person or a group of people and can be edited and updated manually as well as automatically. Posts are usually displayed in reverse chronological order, which means that the latest post is at the top, followed by older posts. Depending on the blogging software used, blog entries can be viewed online in real-time or can be stored and downloaded for later review.

Most blog websites are self-hosted, and therefore, there is no need to maintain a server or network of servers. Self-hosted blogs can either be word-press based or blog platforms such as Blogger, WordPress, Joomla, and Drupal. Word-press blogs tend to be more flexible since they use a plugin system to add features such as auto-posting, logging, and templates. On the other hand, word-press based blog sites usually do not have any support for third-party plugins. On the other hand, Joomla and Drupal based blogs tend to be more stable and generally available in a wider range of formats (PowerPoint and PDF, for example, than RSS feeds and word documents).

A travel blog allows its readers to write blog entries about their travels, while encouraging other travelers to visit the blog section for information about local landmarks, restaurant reviews, etc. In other words, a travel blog can be a sort of online journal or diary, chronicling a traveler’s various trips around the world. Blogs in this niche are also popular among other bloggers since they tend to answer questions and concerns more freely than corporate blog sections do. Travel blogs can be either personal or business blogs. In both cases, the travel blog section can be used as a sales platform by promoting your products and services on your blog.
