Look at your article from various points of view and try to see it in a unique light, and then use this newfound angle to construct a title that will make people want to read more. There are various approaches to this. As with this article, you can opt for the shocking title, using visceral words that hit the reader in the gut and make them wonder what the article is about. There are suggestive titles which lead the reader to view the article. While I am not as fond of using these, I've often found myself reading more of other people's articles because of a suggestive title.
Titles can allude to the content, giving the reader a taste of what's in store.
Just make sure that taste is an appetizing one. This involves taking some element of your article and alluding to it by using a related idea, concept, etc. It is human nature to categorize and label, as it is often an effective timesaving mechanism. You might just notice that your articles are getting more attention. Above all, be creative.
