Difference b/w Article and Blog

A Blog Post
For a piece of writing to be considered a blog post, the most important thing is that it is housed on a blog, which simply means a website or section of a website where updates are posted regularly in reverse chronological order (the most recent post appearing first).
Originally, blogs were personal in nature. Although that’s certainly not the case today, blog posts still tend to be more conversational, casual, and involve more opinion than most articles. They may directly address the reader as “you” and invite the participation of the audience, usually through comments. Blog posts also tend to be shorter than articles, usually no longer than a page and sometimes even just a single paragraph.

An Article
Articles are more likely to be fact-based – a simple reporting of the news. (Most items posted on news sites are considered articles, although some have blogs as well.) They are most often formal, structured with a clear introduction, middle, and conclusion, written in the third person, and objective in nature. However, some articles are written with the goal to change the opinion of the reader or move them to action.
Articles are more likely to include detailed research, quote authorities, and source information, and they are less likely to promote conversation or offer the ability to comment. And articles are often several pages long, though they don’t need to be.
