First of all, what is a blog?
Short for weblog, is a frequently updated web page used for personal commentary or business content.
A blog is said to be a discussion published on the WWW which is the World Wide Web consisting of discrete, often informal diary-style text entries (posts). On most websites, posts are displayed in reverse chronological order, with the most recent post appearing first. A blog was usually written by one individual or a small group up until 2009, and it covered a single subject. A new genre of blogging emerged in the 2010s called MAB, which featured writing from multiple authors and was sometimes professionally edited. MABs from newspapers, other media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog traffic. The rise of Twitter and other "microblogging" systems helps integrate MABs and single-author blogs into the news media. Maintaining or adding content to a blog is also possible as a verb.

Blogging emerged and grew in the late 1990s at the same time as web publishing tools that allowed non-technical users to post content without having much experience with HTML or computer programming. Previously, publishing content on the Web required knowledge of technologies such as HTML and File Transfer Protocol, so early Web users tended to be hackers and computer enthusiasts. Blogs, as a form of social networking service, are one of the most popular Web 2.0 websites in the 2010s due to their interactive nature, which allows visitors to leave online comments. It is true that bloggers not only post content to their blogs but also often build relationships with their readers and other bloggers.[3] Some blogs, however, do not allow comments.
