Writing a search engine optimization (SEO) article is very different from writing stories, poems, novels and other reading materials. It really is supposed to capture the attention of the reader and be interesting enough to keep them glued to the article. Therefore the writer must have exceptional writing skills. Another thing is the grammar used, the reader must not get the impression that the writer is poor in language, they might attribute it to a poor quality of the item or services the article is supposed to be selling, advertising or promoting.
