I don’t know if there are lots of internet marketing people who have observed that blogs can increase your link popularity and page rank easier than articles. In my case, this is what happened. The page rank is increasing with one or two points higher after a month or two. Although articles also help in increasing your site page rank, blog is better.
If articles are better in maximizing the exposure of your business presence in the internet, blog on the other hand, are better in increasing your link popularity and page rank. So far, the surveys revealed that most of the customer-drawing strategy that works is though article writing. Very seldom that conversions or sales are traced back to a blog.
To answer the question, one is better from the other in different aspects. Blogs are better in increasing your page rank and ranking in the search engine listing because they are great factor in relevancy and fresh contents. Articles are better in drawing customers or convincing them to purchase your product because it is authoritative and marketing driven.
This write up does not, however, suggest that you have to choose either of articles or blogs for your web marketing venture. Instead, this voices out the importance of using the power of the two SEO factors. After all, SEO is not all about achieving higher ranking in the search engine results page or get voluminous traffic. It is all about generating sales for your business.
