Blogs have come as a means to convey your message in a personal way. Articles are usually considered more accurate information and the details are concerned. From the standpoint of search engine, the two are a great source of information. But what sort of better?
First, we will see the value each brings:
Blogs:
Timely, personal, “inside views” are usually updated frequently
Articles:
Informative, authoritative, detailed marketing, driven.
From the perspective of freshness, Blogs clearly win over the articles.
Exposure:
Unless your blog is of high rank, the articles have a greater exposure, as there are more chances that your article is seen by more people. There are many sources online that you can send your articles to, here’s a link for some: TechMafia.org and KerrySeo.co.uk
From a business perspective, I can say that the articles that help reinforce what they are selling. When writing an article instead of a blog, there is a perception that more care is taken to write an article, so the information contained in the heavier penalty.
People know that a blog will have a personal twist to it, if the author is the cleaning of a company, or the promotion of something that they have a personal or professional interest in.
In my own opinion, no one has made any purchases of any product that is pushed on a blog, but has a distinct influx of sales can be directly attributed to an article.
So what does this mean for you?
If you have a product or service you promote, use an item. If you need to get something from his chest, creating a blog. While both are considered very good for search engines, you are the ultimate goal is to make users not to confuse the search engines.
