To write an enticing blog piece you need to start with a concept and possibly a final conclusion. Writers should usually have a focus on the direction that a particular article should follow. By using colorful vocabulary and laying out your arguments in a concise manner, it will provide the groundwork for a very well-written post.
But consider the addition of graphics in articles where you need to break up the page. How do these affect the flow of reading? I have always enjoyed when articles break with imagery because the interface is often so cluttered. A small photograph or complimentary graphic helps add some white space in-between large blocks of text.
