Your products sitting right where people are comparing options, with third-party CSS most agencies don't bother with, cutting your CPCs by around 20%.

On average we bring our clients £6.70 in revenue for every pound they spend.

YouTube Ads

Video is the most powerful way to build genuine demand before someone's even started searching. We tie every campaign back to real, measurable conversions.

That approach doubled SellerAmp's conversion rate.

Meta Ads

Introducing you to people who don't know you yet, and bringing back the ones who nearly bought, engineered around your actual customer data.

Ancient Warrior has sustained over 3x ROAS with us, exceeding 5x at peak trading periods.

Microsoft Ads

The same high-intent buyers as Google Search, competing in a far quieter, cheaper auction most businesses overlook entirely.

We've generated over £50M for clients across every channel we manage.

ChatGPT Ads

Where search is heading next. We're already building and running early campaigns for select clients in this space.

We’ve worked with James for a number of years now, having moved from a large, national agency. He is a highly effective PPC Manager and a true extension of our team: knowledgeable, technically gifted, a great communicator, trustworthy, and instrumental in significantly increasing the performance of our campaigns.

We are about to finish our second full year of working with James. Over that period, Trail.co.uk, our camping website, grew by around 40% from 2023 to 2024, and a further circa 17% from 2024 to 2025. Our home and garden site, Christow.co.uk, grew by around 7% from 2023 to 2024, and a further circa 17.6% year on year.

James has been nothing short of excellent. He manages our paid ads and social campaigns for Workever, and the results have been outstanding. From strategy through to execution, he’s proactive, data driven, and constantly optimising performance to get the best return possible.
Damien KWorkever
We’d worked with other ads agencies before and always felt a bit in the dark. Miller Digital has been the opposite: communication is quick, transparent and proactive, and performance has noticeably improved since they took over our Google account. Feels much more like a partner than just another agency.
David CTrinergy
After a bad experience with an agency I sought to find a freelancer to take over our Google and Meta ad management. I had an initial consultation with James and he instantly filled me with confidence. I have since recommended his service to a close friend and would not hesitate to recommend again.
Tyler HAncient Warrior
I’ve worked with James on a handful of projects over the years and he’s one of the sharpest people I know when it comes to PPC, tracking, analytics and overall strategy. What I rate most is that he genuinely understands the bigger picture behind performance marketing, not just the ads themselves.
William CTouchpoint
James has been influential in growing our online revenue though PPC over the past four years. He’s friendly, communicative and extremely knowledgeable on Google ads and social ads strategy, and our results have been brilliant. Highly recommend.

Night and day compared to my last PPC agency. James and team got me more leads and better quality pretty much immediately.
Sam KSK Electrical
James setup our campaign quickly and achieved excellent results. Look forward to the next campaign! Highly recommended.
Eric WFischer-Z
Our team had a fantastic experience working with James at Miller Digital on our Google Ads. He was incredibly detailed and thorough, keeping us updated at every step! We would definitely work with James again in the future.
Aisha AProvision Events
I've been a Personal Trainer for over 10 years. I recently tried to break into the online market. I struggled on my own juggling my day to day work and adding a new area I don't fully understand. Miller Digital have helped me get loads of new paying clients over the past year and a bit. I am able to focus more time on my day to day clients while receiving more frequent and better leads to my business. Appreciate their support in my business growth during this time. 10/10 would recommend.
