UKThe Google Ads agency retailers call when the spend is up but the profit isn't.
Sumoblue is a Dublin-based ecommerce growth partner specialising in Google Ads, Shopping, Performance Max, and Merchant Center. We start with a diagnostic — not a pitch — and forecast the revenue your account can realistically deliver before you commit to working with us.
Google Partner and Shopify Partner since 2017. Winner, Digital Media Awards — Retail & Consumer Goods. Trusted by Irish, UK, and U.S. retailers selling physical products at scale.
Retailers who
trust us
We diagnose accounts before we propose to manage them.
Most retail Google Ads accounts are leaking revenue quietly — through feed issues, Performance Max black boxes, broken tracking, or branded spend dressed up as incremental growth. We find those problems first, in writing, with recoverable spend estimated and the fix mapped out.
If the diagnostic shows we can help, we forecast 12 months of
revenue across three scenarios before either of us commits. If it doesn’t, you keep the diagnostic and we part on good terms. Either way, you leave knowing more about your account than you did when you arrived.
We charge flat fees. We don’t earn a percentage when budgets go up. The retailers we work with are the ones who noticed.
Where we focus. And where we don't.
A Google-specialist agency for retailers selling physical products. Three areas of work — all built around margin and signal quality.
Google Ads, Shopping & Performance Max
Account structures rebuilt around margin and intent — not match-type theatre. We separate brand defence from non-brand acquisition honestly, so reported ROAS reflects real incremental contribution. Performance Max done with the controls most accounts aren’t using: asset group structure, brand exclusions, search themes, and the reporting workarounds needed to actually see inside it.
Merchant Center & Feed Engineering
Where most retail growth is silently lost. We work feed quality, GTIN coverage, custom labels, supplemental feeds, disapproval recovery, and product-level diagnostics as a discipline. Six- and seven-figure issues hide in feeds that look “fine” — finding them is most of the job.
GA4, Tracking & Revenue Forecasting
Optimising on broken data is just expensive guessing. We audit GA4, enhanced conversions, consent mode, and server-side tracking before touching a bid. Then we model 12 months of forecasted revenue by channel and season — so you have numbers you can defend to a board, not promises you can’t.
The work, and what it changed.
Retail and D2C engagements where the diagnostic found something the previous setup missed — and the forecast held.

Start with the diagnostic. Decide afterwards.
We’re taking on a limited number of new retail clients in 2026. The first step is always the same: a paid diagnostic of your Google Ads, Merchant Center, GA4, and feed. You leave with a written report and recoverable spend estimates, whether you go on to work with us or not.
Speak directly with the person who’ll run the diagnostic. No account managers, no sales reps.
