Many people engage in article marketing in order to build their reputation and add to their credibility.
  By having articles about interesting topics in their profession posted all over the web, an otherwise unknown author can become an internationally recognized expert in their field of study.
  Many of these would-be experts are damaging their credibility by making big mistakes with their resource box.
  Read on to learn how: 1.
    They oversell.
  Your article should be constructed in a way to build the reader's interest and entice them to buy your product (or at least learn more).
  Your resource box, however, should not be used for a final hard sell.
  Many people make the mistake of becoming aggressive in their article box, hoping to seal the deal.
  The resource box should provide a brief background on the author and provide links to places to learn more.
A hard sell just reduces credibility.
   2.
    They list every website with which they have an affiliation ...
and their hobbies ...
and a link to their resume.
  Again, the resource box should provide a brief background on the author's experience and places to find more information.
  If you list every website you're involved with and every job you've ever had, you distract the reader from your expert status in that particular area of study.
3.
    They try to sell unrelated products.
  If you want to sell a book on getting a job, your articles about dating are not the best place to make the pitch.
  Keep your (limited) sales pitch in the bio box restricted to products that relate to the attached article.
