How One CTA Change Doubled Conversions and Halved CPAs
In this episode of The Revenue Room, Harry runs solo through a live case study from one of our healthcare clients, where a series of small, logical fixes to the user journey has just delivered a record-breaking week. It’s a short-format episode designed to show what happens when you stop optimising ads in isolation and start optimising the entire flow your leads move through.
Most businesses pour budget into paid media but lose huge volumes of potential customers in the gaps between lead capture, sales follow-up, consultation, and invoice. The data is usually sitting there, but nobody’s taken the time to map it end-to-end. When you do, the opportunities to move the needle quickly become obvious, and often it’s the smallest changes that produce the biggest results.
In this episode, we cover:
Why optimising paid media alone has a ceiling, and where the bigger gains actually live
How to run a two-week audit that maps every user flow, comms touchpoint, and drop-off
Why bringing fresh eyes into a business uncovers gaps internal teams have stopped seeing
How to identify which fixes will move the needle most and avoid overwhelming the team
The single book-now CTA change that broke a weekly consultation record by Wednesday
Why striking while the lead is hot is the highest-leverage moment in any funnel
How to spot the silent drop-off points between invoice and payment, and how to fix them
Why simple, lean workflows beat complex edge-case automations every time
Why consistent creative refreshes are non-negotiable for high-spending paid accounts
We share the real numbers behind the changes, including a 120% increase in Meta-driven consultations, a 150% increase from TikTok, and CPA reductions of over 50% across both channels.

The Revenue Room – Episode 021 Highlights
Host: Harry Hughes
Topic: A live case study from a B2C healthcare client, where a two-week audit of the full customer journey led to one call-to-action change that produced a record week for consultations and cut cost per consultation by more than half.
The Context
The client is a high-volume B2C healthcare brand that MMG has run paid media for across Meta and Google for just over a year. The scope recently expanded to cover CRM management, so the team is now responsible for what happens after the lead: the sales call, the in-person consultation and the paid invoice.
The Two-Week Audit
Before changing anything, the team mapped the whole journey.
Every route into the business, laid out on a Miro board
Every email, SMS, campaign and automation in each flow
At least a year of data to find where the largest drop-offs sit between stages
Sessions with the sales team on what they hear from leads every day
It is resource intensive, and it is where outside eyes help. People who have looked at the same flows for four or five years stop questioning them.
The audit also produced a playbook for the development team on which reporting metrics and dimensions were missing.
Prioritise, Don’t Overwhelm
An audit like this throws up a hundred possible changes. Handing over all hundred helps nobody.
Start with the earliest stage in the journey, where the most volume is lost
Fix one stage, then move to the next
Match the pace to the size of the team
The Change: A Book Now Button
There are two ways to become a lead: book a call with sales directly, or complete an online assessment. Thousands of people a month completed the assessment and were told they would get a call back at some point.
The call arrived from an unknown number, so answer rates were low
Few people were booking a call directly
The fix was to offer a book now option the moment the assessment was completed, when intent is at its highest.
Scheduled calls rose sharply within hours
By the end of Wednesday, the business had already beaten its weekly record for in-person consultations
Nothing else was changed during that period
The Numbers
Compared with the previous period, for booked consultations:
Meta: 120% increase, with a 54% decrease in cost per consultation
TikTok: 150% increase, with a 60% decrease in cost per consultation
Harry is clear these are early results that need to hold over three to six months. If they do, the business can afford to spend considerably more on acquisition.
Why Paid Media Specialists Should Care
Ads can be optimised to the nth degree, but if the flow behind them is missing a call to action or a message, there is a ceiling. Fixing the journey makes every pound of ad spend work harder. Lead volume stays the same and conversion rate rises.
The next stage on the list is invoice to payment, where around four in ten invoiced customers don’t pay and there are gaps in the follow-up communication.
Keep the Workflows Simple
When rebuilding flows it is easy to design for every edge case. That creates a headache for developers and ten workflows to update when something changes. Simple flows are easier to report on and easier to learn from.
A Reminder on Creative Fatigue
New creative had been paused for a while as the client restructured its internal creative team, and cost per lead crept up. Once fresh creative launched into the same campaigns and ad sets, with nothing else changed:
Leads rose 75% against the previous period
Cost per lead fell 42% across Meta and TikTok
The more you spend, the more new creative you need.
Key Takeaways
Paid media performance has a ceiling if the journey behind it leaks
Map every route, message and drop-off before changing anything
Fix the earliest, highest-volume stage first
Reach leads at the moment of highest intent
Keep workflows simple
Refresh creative consistently on high-spend accounts
