The Legacy of John Caples

Marketing built
on proof,
not promises.

We are a data-driven direct-response agency carrying John Caples' tested advertising principles into every campaign we build, every channel we activate, and every result we deliver.

What We Do

End-to-End Marketing
Solutions That Deliver

Six integrated disciplines. One obsession: measurable results that compound over time.

01

Brand Strategy & Identity

We build brands that stand for something. From positioning and messaging architecture to visual identity systems, we give you a foundation that earns trust before a single ad is placed.

Analytics & CRO

John Caples ran split tests in 1927. We run them in real time. We instrument your stack, build attribution models, surface actionable insights, and run rigorous experiments that lift conversion rates.

They Laughed When I Sat Down at the Piano — But When I Started to Play!
John Caples — 1927, the most famous headline in advertising history
The Caples Legacy

We inherited his rigour.
We built on his results.

John Caples didn't guess. He tested. In an era before split-testing software, he wrote competing headlines, measured responses, and documented what worked. His 1932 book Tested Advertising Methods remains required reading in every serious marketing programme.

We carry that discipline forward. Every campaign we run begins with a hypothesis. Every creative variation is tested. Every budget decision is justified by data. We don't spend your money on hunches.

The digital age gives us tools Caples never had — real-time attribution, multivariate testing, behavioural analytics — but the underlying principle is identical: never guess when you can know.

Work that speaks
in numbers.

E-Commerce Retailer

Scaling a DTC brand from $2M to $14M in eighteen months

612% increase in attributed revenue

Through a full-funnel performance marketing rebuild — eliminating wasted spend, restructuring campaigns around lifetime value segments, and deploying rigorous creative testing — we turned a stagnant ad account into the brand's primary growth engine.

Regional Healthcare Group

Owning the local map pack across 24 clinic locations

#1 map-pack ranking in all 24 markets within 9 months

A comprehensive local SEO programme — technical audits, citation rebuilds, review velocity systems, and hyperlocal content — elevated a regional healthcare group to top visibility in every target market, driving a 44% increase in appointment bookings.

B2B SaaS Company

Reducing cost per qualified lead by 68% in 90 days

68% reduction in cost per qualified lead

By repositioning paid search around intent signals rather than keyword volume, rebuilding landing pages around a single conversion action, and deploying systematic A/B testing, we dramatically improved lead quality while reducing acquisition cost.

Professional Services Firm

Building a thought leadership engine that generates inbound at scale

3.4× increase in organic inbound pipeline

A 12-month content strategy combining long-form editorial, strategic guest placements, and a newsletter programme transformed a firm with zero content presence into a recognised industry voice — producing qualified inbound opportunities every week.

Client Voices

What our clients say

"Caples Digital don't just run campaigns — they run experiments. Every recommendation comes with a rationale and a measurement framework. After two years together, I finally understand where every dollar of my marketing budget goes and what it returns."
Sarah Reinholt CEO, Meridian Commerce Group
"We'd worked with three agencies before Caples. The difference is accountability. They set targets in writing, track to them publicly in our monthly review, and when something underperforms they come with a tested fix — not an excuse."
Daniel Krauss VP Marketing, Harfield Medical
"In the first six months they ran more structured tests on our website than our previous agency ran in three years. The cumulative lift from those experiments now accounts for roughly a third of our annual revenue growth."
James Prescott Founder, Vantage Platform
