Frustrating, right?

If you want to stand shoulder-to-shoulder with the best copywriters, this is how you start.

If you don’t know who John Caples is... you’re missing a critical piece of your copywriting education.

John Caples was one of the top copywriters of all time — a true pioneer in direct-response advertising. He wasn’t some “artsy” writer obsessed with cleverness. He cared about one thing: getting results.

In fact, one of his most famous John Caples headlines ("They Laughed When I Sat Down at the Piano—But When I Started to Play!") became a legendary example of how powerful emotional storytelling can sell like crazy.

But here’s the real reason you should care:

Caples didn't just talk about how to write great ad copy. He tested it. Measured it. Tweaked it. And Tested Advertising Methods (his best-known book) is a pure playbook based on what actually worked — not theory.

Why not go straight to the source?

Bottom line:

If you master the lessons inside Tested Advertising Methods, you’ll shortcut your way past years of confusion... and start positioning yourself alongside the best copywriters in the game.

​

One of the biggest slaps of reality you'll get from John Caples Tested Advertising Methods is this:

Vague promises don’t move people. Specific ones do.

Caples saw it firsthand after testing thousands of ads. He learned that the more specific you are with your claims, the more believable — and irresistible — your great ad copy becomes.

Here's a quick example:

• General: "Lose weight fast!"

• Specific: "Lose 5 pounds in 7 days — without giving up your favorite foods."

See the difference?

Specifics give your reader something solid they can latch onto. They feel real. They feel achievable.

In Tested Advertising Methods, John Caples flat-out says: “Be specific. Make your claims definite.”

He even warns that using general, fluffy language will make your ads sound like every other “me-too” message out there — and your prospects will tune you out.

If you want to be one of the best copywriters (the ones clients chase down and pay top dollar), you can’t afford to be vague.

Specifics trigger trust. Specifics build credibility. Specifics make your offer tangible in the reader’s mind.

Next time you write copy — whether it’s a headline, a cold email, or a landing page — ask yourself:

“Am I making a specific promise my reader can picture, or am I hiding behind weak, general words?”

The copywriters who master this (and apply it the way John Caples teaches in his books) get clients faster. Period.

​

If there’s one thing John Caples would roast a lot of modern copywriters for, it’s this:

Trying too hard to sound smart.

In Tested Advertising Methods, Caples drives home a brutal but freeing truth:

The best copy isn’t complicated. It’s clear, simple, and easy enough for a 12-year-old to understand.

He even said, “The most frequent reason for unsuccessful advertising is advertisers who are so full of their accomplishments that they forget to tell us why we should buy.”

In other words...

Nobody cares about your fancy words.

Nobody’s impressed by how clever you are.

Nobody has the time or energy to figure out what you’re trying to say.

They care about what’s in it for them... and they want it served up on a silver platter, not hidden behind a wall of jargon or cleverness.

If you study the John Caples headlines and body copy examples inside Tested Advertising Methods, you’ll see just how brutally simple his writing was — and why it worked.

Here’s the mindset shift:

• Bad copy tries to impress.

• Great ad copy tries to communicate.

You’re not writing to win awards.

You’re writing to get someone to act.

This is why the top copywriters and smartest marketers (especially the ones who studied John Caples books inside out) always prioritize clarity over creativity.

When you’re staring at your next email or sales page, ask yourself:

"Would a distracted, busy, half-interested reader instantly get why this matters to them?"

If not, it’s time to simplify. (And trust me... that's one of the best copywriting tips you’ll ever use.)

One of the biggest copywriting tips John Caples drilled into his students was simple:

People care about themselves. Their problems. Their desires. Their dreams.

If you want your great ad copy to actually get attention and pull readers in, you have to make it immediately about them — not about you, your product, or how "awesome" your service is.

Inside Tested Advertising Methods, Caples says it straight:

“The most frequent reason for unsuccessful advertising is advertisers who are so full of their accomplishments that they forget to tell us why we should buy.”

When your headline or lead talks about features instead of what the reader gets, you're dead.

Let’s look at an example:

• Boring feature-driven headline:

“Our New Software Has a Sleek, Upgraded Interface!”

• Reader-focused, self-interest headline (the Caples way):

“Get Twice As Much Done In Half The Time — With Software That Practically Runs Itself”

Big difference, right?

One talks about you... the other talks about them.

The best top copywriters today — the ones commanding the highest fees — obsess over this. They open every email, ad, and sales page by hammering the reader’s self-interest first and fast.

And it’s not just about the headline either.

Throughout your whole piece, every sentence should feel like it’s answering the silent question bouncing around in your reader’s head:

“What’s in it for me?”

The more you nail that, the faster you’ll separate yourself from the sea of struggling freelancers who are still writing "about us" copy nobody cares about.

If you take anything from John Caples Tested Advertising Methods, make it this:

Appeal to self-interest fast — or lose the sale.
