The two most critical parts of your article are your title and your resource box.
Effective article marketing is about maximizing both the number of readers; which is the job of your title and the number of click throughs; which is handled by your resource box.
I have covered the essential skills for writing great titles elsewhere; now I will focus on crafting an effective resource box.
Here are the three most important attributes.

1. Keep it short.
   Resource boxes are meant to be sharp tools, not blunt instruments.
   Try to avoid bludgeoning your readers with multiple paragraphs of information about you, your website and your amazing experiences.
   Four or five lines of information leading them to want to click your link and come through to your site will be more than enough.
   
2. Focus on benefits.
   The reason people don't want to read about you is because human nature doesn't work that way.
   We are all interested in what we can get.
   The question your resource box should be answering is the one at the forefront of the reader's mind, "What's in it for me?" Answer that question by listing the benefits they can gain from your site.
   A free newsletter; a downloadable report; more in-depth information; solutions to their problems; whatever you offer, your resource box is where you have to persuade them that they want it.
   
3. Blend it into the article.
   Although you enter the information for your resource box, into a separate box on the submission form, this is not how it will appear in your article.
   Click on one of your already submitted articles and you will see that the resource information actually forms the last paragraph or two of your article.
   

Take advantage of this by creating a custom resource box for each article you write, so that the readers eye is drawn into your final offer, almost without them being aware that they are actually now not reading the article at all.
