Shopify Google Ads
Google Ads for Shopify Brands That Need Profit, Not Just Revenue
Most agencies run Shopify accounts the same way they run everything else: install the Google & YouTube channel app, accept the default feed, point Performance Max at the catalogue, report ROAS. It works just well enough that nobody questions it - while margin leaks through default feed mappings, untracked returns, and bids that treat a 15%-margin SKU like a 60%-margin one. JudeLuxe runs Google Ads for Shopify and Shopify Plus brands the way the P&L would run it.
Why "set up the channel app and run PMax" quietly costs Shopify brands money
Shopify is the cleanest ecommerce platform to advertise from - which is exactly why it produces complacent Google Ads management. The defaults are good enough to function and bad enough to leak.
The default feed is built for coverage, not profit
The Google & YouTube channel app maps your catalogue with 60-70% attribute completeness and titles written for your store, not for the Shopping auction. No programmatic title construction, no custom labels carrying margin or stock data, no supplemental feed layer. Every bid decision downstream inherits that blindness. Feed engineering - via middleware or Shopify's native metafields pushed into supplemental feeds - is where Shopify accounts are won.
Shopify tells you revenue. Google needs to know profit.
Your Shopify admin knows COGS, shipping cost, return rates and discount cannibalisation. Your Google Ads account sees none of it unless someone builds the pipe. We push contribution-margin data into the account as conversion value - so Smart Bidding optimises toward POAS, not gross checkout value. This is the difference between a 4x ROAS that loses money and a 2.5x ROAS that funds the business.
PMax eats Shopify brands that don't structure it
One catalogue-wide Performance Max campaign is the default recommendation - and the fastest way to let your bestsellers subsidise your loss-makers invisibly. We structure asset groups around BOI® commercial jobs - Scale, Profit, Protect, Recovery, Gateway - with brand exclusions and value rules per group.
More on how we structure this in Performance Max management and the BOI® framework.
What Shopify-specific management actually involves
Four functions, run as engineering discipline rather than an account-management retainer.
Feed engineering on the Shopify stack
Metafields pushed into supplemental feeds for margin, stock and seasonality data. Programmatic title rebuilds for the Shopping auction. Variant handling that doesn't fragment impression data. Middleware (DataFeedWatch, Channable) where the catalogue justifies it; native channel app where it doesn't. We choose based on catalogue complexity, not a reseller arrangement.
Margin-true conversion tracking
Server-side tracking via Shopify's pixel architecture, net-of-returns conversion adjustment for high-return sectors, new-vs-returning customer value separation (so you stop overpaying for sales you'd have got anyway), and contribution margin passed as conversion value. Board-ready numbers, not platform-flattering ones.
Shopify Markets and international
Selling through Shopify Markets into the US, EU or UAE changes feed structure, currency handling, and margin per region. Regional margin targeting is how Flavour Blaster grew US revenue +250%. Full detail in our International Google Ads page.
Subscriptions, bundles and AOV mechanics
Recharge or native subscriptions need LTV-aware acquisition pricing - first-order economics lie. Bundles need their own feed entries and bid logic; Husk & Seed doubled contribution margin moving from loss-making samples to profitable bundles.

Read the case studyWhen you don't need us
We push back on engagements that won't work - even when it costs us revenue.
01
Spending under £15k/month
You need a freelancer or strong in-house operator, not us. The fee maths doesn't work in your favour yet.
02
Margins are uniform across the catalogue
If everything carries the same margin, ROAS and POAS converge and our edge shrinks. Rare, but it happens.
03
You can't share margin data
POAS bidding requires COGS at SKU level. If that data can't leave finance, we can't do the thing we're good at.
04
You want Meta and TikTok under one roof
We run Google and Microsoft Ads only, alongside specialist partners. If single-vendor matters more than depth, we're the wrong shape.
Frequently asked questions
Do you work with both Shopify and Shopify Plus?
Yes. Plus matters for checkout extensibility, B2B pricing and Markets complexity, but the Google Ads work is driven by catalogue economics, not plan tier. Typical client: £3M-£100M+ revenue, £15k-£500k/month spend.
Do you use the Google & YouTube channel app or a feed tool?
Whichever the catalogue justifies. Under ~500 simple SKUs, the native app plus supplemental feeds is often enough. Variant-heavy, multi-market or high-SKU catalogues need middleware. The decision is about attribute completeness and title control, not tooling preference.
How do you get profit data out of Shopify and into Google Ads?
COGS via Shopify's native cost-per-item (or your ERP if it's the source of truth), returns netted off, contribution margin pushed as conversion value. Smart Bidding then optimises toward profit. Setup typically lands in the first 30 days.
Can you fix a PMax campaign that's already running?
Yes - that's most engagements. Read-only audit first, then staged restructuring: brand exclusions, asset groups rebuilt around commercial jobs, value rules. We don't reset learning overnight; transitions are managed over 30-60 days.
What does it cost?
Fixed monthly fee based on catalogue complexity and spend - never a percentage of spend. 3-month initial engagement, then month-to-month with 30-day notice. Minimum £2k/month fee, £15k+/month media spend.
Do you handle the rest of the stack - email, CRO, Meta?
No. Google Ads and Microsoft Ads, deep. We work alongside specialist partners for everything else and tell you when the constraint isn't the ads.
