yes. yes. yes.
A well-crafted headline is half the battle. Without it, even the best of content may never get read - as it's the headline (and accompanying picture) that initially grab a reader's attention and inspires them to click, or move on for something more appealing.
There's fundamental principles of copywriting psychology that are well put into use when writing headlines, if people want people to open their articles. There's a science to it.
Every small detail matters.
Capitalizing the first letters of each word MATTERS.
Condensing the wording down to only what's necessary to convey the message - stripping away unnecessary words - MATTERS.
The use of proper punctuation, grammar, spacing - MATTERS.
Leading the reader with a promise of VALUE to be found upon investing their time in reading the rest of the article is KEY. (And fulfilling upon that promise by delivering such value is key in assuring the reader is satisfied with what was promised by the headline).
The more one develops their copywriting skills - analyzing the finest details of how a headline is crafted to elicit specific responses in readers, just as the language of computer coding is critical to refine if desiring to execute a specific program/command - the better they'll also be able to create the body of text for the rest of their articles.
Excellently written piece. Not one to overlook the value in. :-)
