Good advice, Stacie & Relache.
However, TC, not everyone wants to read longer hubs. Two of my three "most viewed hubs" are rather concise. I'm logician. As a journalist, you know the conventions & elements of writing. But do you know the psychological perspectives of writing?
In short, (1. hub length) most men want 'em short & to the point; most women want the extended journey into the creative wordplay of the hub. (2. hub name) if it's a hub aimed at women or more appealing to ladies, use a title that speaks to them: "The Art of Composition Using Classical Latin Techniques"--women would read this quicker than a guy. "A Tale of Two Lies"--men. Notice neither title uses gender hints. (3. hub appearance) use bold face, CAPS, other punctuation methods, this effects your score. yes, always use a photos if applicable. (4. don't publish it right away) Initially I didn't immediately publish "Beware of Misleading & Deceptive Hubs" because I wanted it to be a 2-part series. At first the score was about 52, after I half completed part 2, I was ready to pub. But I either misplaced it or accidentally deleted. So when I published part 1 it debuted IMMEDIATELY at 69 score! (5. hub incentives) utilize the capsules "polls, quizzes, links, rss, etc."
These are some tips to improve hub scores.
