Published results, their limits, and what they mean for a UK account
Several engagements are described here. None of them is British yet, so each one ends with the part that carries over to a UK business, and each says plainly what a reader can and cannot verify.
Trutek, truck suspension parts, Brazil
Brand identity, website and Google Ads Search · since 2020 · trutek.com.br.
I created Trutek's brand identity and website and have run its Google Ads account since 2020. The company sells suspension parts for heavy trucks and trailers.
The account's cumulative history shows 5,707 clicks and about 260 attributed contact conversions: a 4.56% conversion rate, R$ 63.61 per conversion on average (Brazilian reais) and a 9.29% click-through rate.
A conversion here is a contact action recorded by Google Ads, such as a message or a form, not a sale. Calls are counted in a separate column and are not added in. The figures are cumulative with no monthly series, so they show the account's level, not a trend. Full case on diwizi.com.
For a UK supplier: a narrow catalogue and few searches mean every exclusion and every enquiry counts. The account is kept tight and measured on contact actions that sales can follow up, not on clicks.
Health plan reseller, Brazil
Google Ads Search and monthly reporting · about eight months, 2019 to 2020 · reseller not named.
I ran the Google Ads account of a reseller of Clinipam health plans, an operator based in Curitiba. My client was the reseller, not the operator, and every campaign had one goal: a quote request submitted on the website.
In October 2019, on almost the same spend as September (about R$ 9,300 a month), Google Ads produced 651 quote requests against 566. Cost per request fell from R$ 16.42 to R$ 14.31 and the conversion rate rose from 18.5% to 23.5%.
From the monthly report I prepared at the time, from Google Ads and Google Analytics. Two months side by side, not a trend. A quote request is a form submitted, not a plan sold. Full case on diwizi.com.
For UK private health insurance or healthcare providers: the quote or booking request is the conversion, and the report has to say plainly that a request is not a policy sold or a patient seen.
Home services: an HVAC and plumbing business in Houston, Texas
Google Ads and Performance Max · May 2025 to February 2026 · freelance engagement, working directly with the business.
One of the hardest auctions I have worked in: expensive clicks, ZIP codes where the areas with the most potential also cost the most, demand that swings between air conditioning and heating, and the same search bringing either a simple repair or a very high ticket job. I kept adjusting services, areas and the budget split as results came in, and tracked cost per conversion, calls and bookings by service, area and season.
The performance data from this engagement is confidential under my contract, so this site publishes no amounts, volumes or percentages from it. Figures that appeared here earlier were removed for that reason. The full write-up is on diwizi.com.
The UK version of this account
Swap air conditioning for boilers and it looks very familiar: emergency boiler repair and new boiler installation fighting over one budget, calls counted whether or not an engineer is booked, and postcodes mattering more than keywords. UK clicks are cheaper, which makes the same waste easier to overlook rather than smaller.
Software: Pontomais, time-tracking and HR software in Brazil
Google Ads · employee, two years from August 2017.
I worked at Pontomais as an employee, and one of my main jobs was rebuilding its Google Ads account from scratch, with landing page recommendations and daily alignment with the sales team. When I started, Google Ads produced roughly five contact requests in a month. Over the following eight months that volume reached the hundreds.
Approximate volumes from my own experience on the project. No original reports or testimonials are published, and spend is not disclosed. Full case on diwizi.com.
For a UK software business: the order of work is the same. Measure trials and demos through to paying accounts, bid on the searches buyers make rather than those made by students and job-seekers, and build each landing page around the trial or the demo.
Big World Jobs, a job board built from scratch
Planning, build and measurement · 2026 · my own project, not a client.
A free job board for every country that I planned, built and measured from scratch: more than 600,000 jobs from more than 8,000 companies in 150+ countries. Full case on diwizi.com.
Education: one of the largest private school groups in Brazil
Enrolment campaigns · client not named.
The target was 5,000 new students. It was met three months ahead of the deadline, with paid media carrying families from the first search through to an enrolment enquiry.
Budgets, cost per enrolment and results by campus are confidential.
For UK schools, colleges and training providers: enrolment runs to a hard deadline, so demand has to be built before the intake rather than during it, and the campaign calendar is set by the admissions timetable, not by the media plan.
Regulated categories: Underscore Marketing, a US pharmaceutical agency
From September 2023 to March 2024 I worked as a freelance paid media operator for Underscore Marketing, on Google Ads and paid social accounts run under the agency's name, across oncology, rare disease and gene therapy brands. Product names, budgets and results stay confidential under the agency's NDA.
For UK healthcare advertisers: the rules are different here, since prescription medicines cannot be advertised to the public at all and health advertising sits under the CAP Code and Google's own healthcare policies. The discipline carries over unchanged: every advert and landing page is written to be approved first time, with claims that can be substantiated.
Published research
Two pieces of first-party research are public on the consultancy's main site: the Paid Media Cost Index, a median Google Ads cost-per-click benchmark across six US industries with its method and date, and a series of ad spend teardowns built from public advertiser data.
Questions people ask before hiring
Why is there no UK case study?
Because none can be published yet with dates and limits attached. Rather than write a vague one, this page shows engagements that can be described properly and what each means for a UK account. The first UK engagement that can be written up the same way will be added here.
Why are some clients not named?
Much paid media work sits under NDAs or compliance rules. Where a client cannot be named, the sector, the scale and the result are given and nothing more. A few engagements with their limits spelled out are worth more than a long list with the limits hidden.
Can I speak to a previous client?
For serious enquiries, yes, provided the client agrees. Mention it in the form or on the call.
What will you promise before seeing my account?
No figure. Anyone who quotes a result before looking at the account is guessing. What I commit to is the order of work: tracking first, then wasted spend, then structure, then testing, with each step reported in writing so you can see what moved.
