Blog is short for web log is a web application that resembles the form of writings (published as a post) on a public web page. These writings are often published in reverse order (most recent content first and then followed the content is longer), although not always so. Web sites like these can usually be accessed by all Internet users according to the topic and purpose of the user's blog. Blog has a very diverse functions, from a diary, media publicity in a political campaign, through media programs and corporations. Some blog maintained by a single author, while others by several authors. Many weblogs also have the facility of interaction with the audience, such as using the guest book and the comments that can allow the visitors to leave comments on the contents of the published writings, but there is also the opposite or non-interactive. how to create a blog is first of all you should have a good account yahoo, google and others.

 Based on some articles I read, things to consider in building a blog is:
1. Focus on one topic contained in the individual posts and post updates as often as you pull through
    2. The layout and theme that makes visitors feel welcome to visit
    3. The addition and modification of special HTML code on the blog page
    4. Addition and selection of keywords or keywords that right
    5. The addition of a blog sitemap
    6. The addition of the blog description
    7. The use of English for each post
