Google Ads ROI You Can See

You pay an agency for Google Ads but still get clicks without enquiries. Decima tracks revenue, reports ROAS in plain English, and builds landing pages matched to your ads. You keep account ownership. Less wasted spend, more enquiries, and a clear view of performance.

Can't recommend enough. They genuinely cared about our business and did whatever it took to get us results, going above and beyond at every turn. Clear communication, super quick to respond, and delivered on everything they promised. Conversions up and ad spend way down in the first month. Trusted them completely.

When Your Agency Hides Behind Vanity Metrics

Every month the invoice lands but you still cannot answer what a lead costs or which keywords produce revenue. Clicks stack up while conversion tracking is weak or missing. Enquiries cannot be tied back to search. Your marketing budget keeps flowing with no clear accountability, and you stay stuck managing an account you never wanted to run yourself.

Why Decima vs Another Google Ads Agency

Packages start from £990/month for management. Ad spend is separate.

  • We track revenue, not just clicks. Full GTM and conversion tracking for forms and calls, plus assistance connecting sales data back into Google Ads so reporting reflects real business outcomes.
  • Ads and landing pages in one team. Generalist agencies often stop at the ad. Freelancers may run Google Ads without owning the page traffic lands on. With Website Management included, the same team can publish landing pages matched to winning search terms within a day rather than waiting weeks on a separate web team.
  • Transparent ROI reporting. Monthly plain-English views of ROAS, conversion value, and what is working. No hidden charges and no percentage of your ad spend.
  • Human-directed AI optimisation. Continuous search term refinement, fresh creative, and new ad groups each month, guided by the Decisive Marketing framework and your Customer Knowledge Graph.
  • Certified Google Partner. Team certified with strong account performance and healthy ad spend management.

★★★★★ Google review

We discovered Decima through their free Google ad clinic which was perfect timing for us as I was trying a different ad strategy with no knowledge on google ad. Alexis definitely knows her stuff and gave me very practical advise on what to do (or not) when setting up my ad and fixed the main issue on my current google ad. As a business owner, you want to be able to focus on your area of expertise and that's exactly what they did for us. I highly recommend Decima, a friendly and obviously knowledgeable bunch!

A clear monthly view of ROAS, conversion value, and what is working — not vanity clicks.

What clients say

Kerry Leighton-Bailey
"As a CMO I've worked with a lot of agencies, and the thing that stands out with Decima is how straightforward the relationship is. There are no hidden charges, no confusing reports full of metrics that don't mean anything to the business. Every month we get a clear view of ROAS, conversion value, and what's working. That's it."
Kerry Leighton-Bailey, CMO, BBD Boom
Michael Dollard
"Before this, we had no idea what a lead was really costing us, and we couldn't touch our own website without waiting weeks on someone else. Now we can see the ads that are converting customers and Decima has been incredibly responsive to new ideas we bring to the table as well. It's changed how confidently we can spend and test out new messaging."
Michael Dollard, COO, QuickTurn Cabinets
Nick Curtis
"Before Decima, we were struggling to piece together what was really driving growth, so we were wasting a lot on Google Ads that weren't doing much."
Nick Curtis, CEO, Bocobay
