The most essential component of a blog is not only its keywords, but also the timeliness of its content. It is timely content that is going to attract the search engine and also readers. This means that you must have content that is unique, expert or original. When your readers add their own comments and links to your blog this expands the search ability of your content. It should also be content that is focused on one topic and that seems specialized, fresh and new.
Another essential component of Blog content is that it must be up to date, just as any news article is. This is also what marketing and advertising experts call "hot content.” Cutting and pasting articles from other sites simply won’t work because the search engine sites will simply ignore what you come up with. Nobody wants to read yesterday’s news. Or you will get a complaint if the page is indexed in the search engines and the content belongs to someone else. When it comes to hot content, originality is key!
Another crucial reason why your content must be original and fresh is because on the blogging page, your content is arranged in reverse chronological order. The most recent content is presented at the top of the visible page and provides immediate access to topics that are most timely (meaning the blogs you have just written.)
Another great thing about a blog is that it is of a viral nature. It can be distributed for free through an RSS, Atom or XML feed that allow readers to subscribe to your entries just like they would a magazine or newsletter. This means that users can subscribe to blog content. This brings repeat business to your site and increases your chances of the affiliate links inside your blogs of being picked up and spread by other affiliate marketers.
