Google Ads for Shopify Stores That Turn Spend Into Profit

We find where your budget is leaking, fix the product feed and campaign structure, then scale only the products that already make money. Not more spend. Better spend.

Not lead-gen ads

What is ecommerce PPC, and how is it different?

Ecommerce PPC is paying Google to put your products in front of people at the moment they are searching to buy. Google Ads for Shopify is not the same job as lead-gen ads. You are not chasing form fills. You are bidding on thousands of individual products, each with its own margin, stock level, and conversion rate.

That is why the product feed matters more than the ad copy. Google decides which of your products to show, using the titles, images, and data in your feed. Get that wrong, and you pay full price for clicks on products that were never going to sell. Most of the accounts we audit are losing money here, not in bidding. It is also why a general PPC agency often struggles with Shopify Google Ads. Feed work is a different discipline from writing search ads.

How product feed titles determine which buying searches Google can match a product to
The four pillars

What is included

Google Ads for ecommerce breaks into four pillars. Each one has a named outcome you can check against.

01/04

Account audit and structure

Full Google Ads audit, campaign rebuild, segmentation by margin and profitability, budget reallocation.

What changes Money moves to the products that can actually pay for it.
02/04

Shopping feed

Product titles rewritten for real search demand, image quality, Merchant Center errors, Google Shopping feed optimization.

What changes Google shows the right products to the right people.
03/04

Campaign management

Shopping, Search, Performance Max, remarketing, bidding strategy, negative keywords, creative testing.

What changes Waste comes out weekly instead of building up quietly.
04/04

Tracking and reporting

GA4, enhanced conversions, server-side tracking, monthly reporting at product level.

What changes You see which products paid for the retainer, not just an account-level ROAS.

Every engagement includes monthly reporting and a strategy call. You see profit by product, not a dashboard of impressions.

Common mistake

More budget is not what fixes a Google Ads account

The instinct when ads underperform is to spend more. It rarely works.

The problem is usually which products you are advertising, not how much you are paying to advertise them.

We took a medical supply store to 699% ROAS in 80 days without increasing the budget. The fix was product selection. The account was spending most of its money on items that could not turn a profit at any bid.

Fit check

Is this a fit?

Good fit if you

  • Run a Shopify or Shopify Plus store with a real product catalogue
  • Can spend at least £2,000/month on ads, enough for the data to mean something
  • Have products that already sell somewhere, organically or through another channel
  • Want to know profit per product, not just account ROAS

Not a fit if you

  • Sell a product nobody is searching for yet, because there is no demand to bid on
  • Run margins under 20%, where paid ads cannot turn a profit at any bid
  • Are in a restricted category like gambling or alcohol, where Google policy blocks scale
  • Want us just to raise the budget and report back

If you are in the second list, say so on the call. We will tell you what we would do instead, even if it is not us.

Straight answers

Common questions

How does Google Ads work?
You bid on what people search for, and you pay when they click. But the highest bid does not win. Google multiplies your bid by a quality score based on how relevant your ad and landing page are, so a better-matched ad can outrank a bigger budget. For Shopify stores, it works differently again: with Shopping ads, you do not bid on keywords at all. Google reads your product feed and decides which searches you match. That is why feed quality, not bid size, is usually what separates a profitable account from a losing one.
How to create an ad on Google?
Create a Google Ads account, pick a campaign type, set a budget and bidding goal, choose your targeting, then write the ad and point it at a landing page. That is the mechanical answer, and it takes about twenty minutes. For an ecommerce store, the sequence is different: connect Shopify to Merchant Center, clear your feed errors, verify conversion tracking, and only then build a Shopping campaign around products you already know sell. Creating the ad is the easy part. Creating one that makes money is the work.
How to set up conversion tracking in Google Ads?
Link Google Ads to GA4, then create a conversion action for purchases and import it. On Shopify, enable the Google and YouTube channels so purchase events pass through automatically, then turn on enhanced conversions so the match rate survives cookie loss. Verify it with a real test order before you spend anything. Around half the accounts we audit have tracking that looks fine in the interface and is quietly double-counting or missing sales. Every optimisation made on top of broken tracking is guesswork.
How do I set up Google Ads for Shopify?
Connect Shopify to Google through the Google and YouTube channel, then send your products to Merchant Center. Fix the feed errors before you spend anything, because disapproved products cannot be advertised. Set up GA4 and enhanced conversions next. Only then build campaigns, starting with Shopping on your proven bestsellers rather than the whole catalogue. Most stores do this in reverse and wonder why the numbers never make sense.
What is your minimum ad spend?
£2,000/month. Below that, there is not enough data to optimise on, and you would be paying us to guess.
What does management cost?
From £800/month for accounts spending £2,000 to £5,000. The fee scales with spend, not with revenue.
How long until I see results?
Google Ads can drive sales in week one, but the account needs data before it is stable. Expect an early signal in 2 to 4 weeks and meaningful improvement by month three.
What ROAS should I expect?
4x to 6x is typical for ecommerce after 90 days. High-margin products and established brands go higher. New campaigns often sit at 2x to 3x while learning.
Can you work with our existing campaigns?
Yes. We audit first and either rebuild or optimise what is already there. Most accounts have quick wins in the first fortnight.
Do you handle the Shopping feed?
Yes, and we built the app that does it. Titles, images, Merchant Center errors, and feed structure are all in scope.
