Headline Craft: Ogilvy, Caples, Halbert, Wiebe

What this is for: Turning Claude or ChatGPT into a headline craft reviewer that generates, scores, and rewrites your titles, subject lines, and social hooks using the formulas refined and tested across nearly a century of direct response.

Who this is for: Newsletter writers and solo creators who keep losing the open-rate battle, the click battle, or the social-feed battle and want a structured way to write headlines that pull the right reader in.

Headline craft is the oldest, best-tested discipline in commercial writing. John Caples started running response tests for advertisements in the 1920s. David Ogilvy built an empire on the principle that the headline is the most important sentence on the page. Gary Halbert taught a generation of copywriters to obsess over the first line and treat the rest as decoration. Joanna Wiebe carried the discipline into the modern web with conversion testing on landing pages and subject lines. Together they describe the same craft from four angles, and the patterns hold across nearly a century.

This post gives you the four of them as a unified context profile. Drop the JSON below into Claude or ChatGPT and ask the model to generate, evaluate, or rewrite your headlines through the combined lens. The model will name the formula, score the specificity, check the front-loading, and warn you when you have used a category of headline the body of your piece cannot deliver on.

What you get

Eight frameworks: How-To, Number and List, Question, News and Announcement, Benefit-First, Curiosity and Intrigue, Social Proof, and the six-criterion Headline Evaluation Test. Plus nine operating beliefs, twelve vocabulary terms, the limits of formula thinking, and the JSON ready to paste.

The thesis

The headline is the highest-leverage sentence a writer ever produces. Five times as many people read the headline as read the body, which means the headline is responsible for most of the work a piece of writing does. Strong headlines are not magic. They follow a small set of patterns refined and tested across nearly a century of direct response, from Caples and Ogilvy through Halbert and into Wiebe’s modern conversion work. Writers who master the patterns stop guessing and start choosing.

Why this matters for newsletter writers

Most newsletter advice is about voice or growth. Headline craft sits underneath both. Before any of that work pays off, your subject line has to earn the open. Your subscribe page has to earn the click. Your social hook has to earn the scroll-stop. A newsletter writer who treats the headline as an afterthought is donating most of their conversion potential to the void. The four authors in this profile spent careers measuring exactly which patterns work and which patterns waste the writer’s effort.

Preview: How-To Formulas

The oldest reliable pattern in the book. How-to headlines promise practical instruction and they work for any audience that has decided they want to learn something. Caples ran them in 1932 ads. Ogilvy used them throughout the 1960s. They still work because they map cleanly to the way readers search and scroll: I want to do something, show me how.

The basic form is “How to [achieve outcome].” That is functional but plain. The strength compounds when you add structure.

A qualifier turns a generic instruction into something the reader feels was written for them. “How to Build a 6-Figure Business (Even If You Have No Audience)” outperforms “How to Build a 6-Figure Business” because the parenthetical names the obstacle the reader actually feels.

A timeframe turns a vague promise into a measurable one. “How to Learn Spanish in 90 Days” beats “How to Learn Spanish” because it tells the reader where the effort ends. Specific numbers always outperform vague ones.

A personal proof line trades the abstract instruction for a concrete success story. “How I Built a $10M Business from My Bedroom” works because the writer is staking the credibility of the headline on a real, named outcome. The reader who clicks expects to learn the actual mechanism. If the body delivers, you have built trust as well as opens.

The how-to category is also the most overused. Most writers default to it. The discipline is to ask whether your piece is genuinely procedural. If it is news, use a news headline. If it is a transformation pitch, use benefit-first. The right formula matched to the right content does most of the work.

That is one of eight frameworks in the full profile. The other seven, plus the operating beliefs, the vocabulary, the limitations, and the JSON you can paste into Claude, are below for paid subscribers.
