There's no doubt that writing articles can help in building your online profile, backlinks and traffic. It seems to me though as an Article Directory site owner that many authors are being very short sighted when it comes to the resource box at the foot of the article, and for a couple of reasons.
Every day I see Resource Boxes with something like the following:-
Fred Bloggs is a top internet marketer and can show you how to make a fortune with his methods. Visit his web site at (embedded site url)Make Your Million Here.
Now what's wrong with this you might ask. Well, it may well get into Article Directories, but as authors you are ignoring a very valuable second opportunity for publication - and one that is exponential. That second source is the publication market. I would suggest to you that an article with a resource box like that is going to have little chance of being picked up for further publication. Secondly, if it was, it has an embedded url link which will not appear in an ezine or web page anyway. Remember, the deal for publishers is to publish the article intact and that doesn't mean adding the html code to keep the link working.
A far better way of doing your resource box is along these lines:-
Fred Bloggs is a proud contributing author and writes articles on several subjects including internet marketing. You can see more of Fred's articles on his web site at An Innocuous Titled Site located at http://www.somesite.com.
This doesn't try and "sell" anything, it is leading people to a link. The http full address in addition to the embedded link, keeps the url intact in the event of publication elsewhere.
These are certainly my thoughts having reviewed well over 1,000 articles now, but I would love to hear other suggestions to how best to word a resource box.
