The best way that I have found is to write shorter articles usually under 300 words and then have a longer then normal resource box. Usually my resource box will be about 100 words sometimes more.
The good part about this is that my resource boxes can be used over and over again so all I really need to worry about is making short 300 word articles.
I have found that these shorter articles get better results... maybe because it makes the reader want to learn more - more effectively? Maybe because they are short and sweet? Not sure what the reason is although I just wanted to share it with all the warriors.
I hope this helps some of you that are struggling to get a high click through rate from your articles.
