Part of creating an eye-catching headline could be using some of the strong adjectives/verbs mentioned in tip #14. So, for example: Kill Your Spammy Backlinks - Before it's Too Late! or here's a good one I came across recently that I would definitely categorize as eye-catching: How Google Glass ruined my lunch hour The goal is to create something that feels, at least to some degree, out of the ordinary. It's hard to give examples because a headline can be eye-catching for many different reasons - because of word choice, punctuation, sentence structure, etc. I hope that helps!
For self-evident reasons the title should be short. Aptness and specificness do not require an epitome of the story; and a title like “Why Tom Changed His Opinion of Me,” or “What the Rabbit Drive Did for Me” is prosy as well as long. It used to be the custom to make the title of a writing a regular synopsis of the matter contained therein; but modern readers object to being told in advance exactly what is to happen. No ruling concerning the proper length of a short story title is possible; but generally speaking, the shorter the title the better it is. Compound titles connected by “or,” like those previously mentioned, are as offensive in their length as in their sensationalism.
