With one step you can increase readership of your headlines. Here’s how: Stop capitalizing every important word in your title. The publishing industry refers to this as the “Up” style, and its use is popular among traditional publishers, such as The New York Times and The Wall Street Journal.
However, research has shown that capitalization actually reduces reading comprehension because it slows down the eye movement and requires the reader take more effort to extract the information.
Readers in general are used to comprehending sentences with natural capitalization – and punctuation for that matter.
The initial caps styling, along with underlining and double spacing after a period, is a relic of bad typewriter design, monospaced typefaces, and limited printing options.
In days of yore, initial caps or even all caps were used to distinguish headlines from the rest of the copy. This is no longer necessary with the advent of bold, italics, and varying font sizes.
So follow the lead of the Associated Press. Ditch the cap-every-word approach. And capitalize only the first word and proper nouns in the headline.
And be sure to end your headline with proper punctuation.
