Retail Google Ads since 2015

Return on ad spend is vanity.
Profit is the point.

Hawthorne Ads runs Google Ads for retailers. We bid on contribution margin rather than revenue, which means the accounts we manage sometimes look worse in the Google Ads interface and considerably better in your management accounts.

What we tend

Six services for businesses that ship boxes.

We work exclusively in Google Ads, and exclusively for retailers. Everything we know is about selling physical product profitably, at scale, across a catalogue that changes every week.

I

Google Shopping & Feed Management

In Shopping, the feed is the campaign. We rebuild titles, attributes and custom labels around margin and stock position, then structure campaigns so your best products get the budget and your worst ones stop quietly draining it.

  • Title and attribute rewriting at scale
  • Custom labels for margin, stock and seasonality
  • Priority-based campaign structures
  • Price competitiveness monitoring
II

Performance Max for Retail

Performance Max will happily spend your budget on shoppers already walking through the door. We separate brand traffic, split asset groups by product family and margin tier, and hold the automation to account with experiments rather than faith.

  • Brand exclusion and traffic separation
  • Asset groups by product family
  • Complete asset sets, video included
  • Experiments before every budget move
III

Search & Brand Protection

Generic category search is where retail budgets go to die, and brand search is where agencies go to claim credit. We manage both honestly, with brand reported separately so nobody confuses defending your name with growth.

  • Category and long-tail search
  • Brand reported separately
  • Competitor conquesting, deliberately budgeted
  • Weekly search term review
IV

YouTube & Demand Gen

The channels that create next season's demand rather than harvesting this one's. Product-led video and feed-linked Demand Gen, measured on incrementality and new customer acquisition rather than on last-click revenue.

  • Product-led video assets
  • Feed-linked Demand Gen
  • New customer acquisition targets
  • Geo holdout testing
V

Merchant Center Health

Disapprovals, price mismatches, missing GTINs and shipping configuration errors quietly remove products from the auction entirely. We monitor the whole catalogue daily and fix the causes rather than the symptoms.

  • Daily disapproval monitoring
  • Price and availability mismatches
  • Promotions and free listings
  • Shipping and tax configuration
VI

Profit Analytics

A reporting layer joining Google Ads cost to cost of goods, delivery, returns and payment fees. It produces one number — contribution profit by product and by campaign — and that is the number we optimise against.

  • Contribution margin by SKU and campaign
  • Return rate modelling by product family
  • Stock-aware budget pacing
  • Board-ready monthly profit reporting
Our method

Five stages, in the same order, every time.

The first two produce no new campaigns at all, which is unusual and occasionally unpopular. They are also the reason our accounts hold up in year three.

I
Weeks 1 – 2

Establish true margin

We ask for cost of goods, delivery cost, return rate and payment fees at product level. Most retailers have never seen Google Ads performance net of all four, and the ranking of their best products usually changes once they do.

II
Weeks 2 – 4

Repair the feed

Titles, attributes, GTINs, images, disapprovals and custom labels. Nothing in Shopping or Performance Max works properly until the product data is correct, and in our experience it almost never is.

III
Weeks 4 – 7

Rebuild the account

Campaigns rebuilt around margin tiers and product families rather than around the way your website navigation happens to be organised. Brand separated so automation cannot claim credit for it.

IV
Weeks 7 – 12

Move budget deliberately

Spend shifts in planned increments with an experiment behind each one. We would rather take three weeks proving a change than three days guessing at it and a quarter unwinding it.

V
Ongoing

Report in profit

A weekly trading call with your buying and merchandising team, and a monthly contribution profit report that reconciles to your management accounts. If the two disagree, we fix the report rather than explain it away.

Results

Accounts where profit went up and revenue sometimes did not.

Selected engagements. Client names withheld under commercial confidentiality. Figures are twelve-month like-for-like and drawn from client management accounts, not from the Google Ads interface.

Homeware · £14m turnover
+38%
Gross profit

Revenue fell 6%. Nobody minded.

Half the catalogue was being advertised below true margin once delivery and returns were counted. We excluded 2,100 products from Shopping and Performance Max, moved the budget into the profitable third, and the business made materially more money on slightly less turnover.

Apparel · Multi-market
−29%
Cost per acquisition

The return rate changed everything

Returns ran at 41% on one product family and 8% on another, and both carried the same target return on ad spend. We built return-adjusted targets by family using custom labels, and let Smart Bidding optimise against a number that reflected reality.

Pacing tied to stock, not to a calendar

Demand arrives in an eleven-week window and stock runs out unevenly. We built pacing that reads stock levels daily and pulls spend off lines about to sell through, so nothing was advertised into an out-of-stock product page.

Why Hawthorne

Specialists, and deliberately narrow.

One platform, one sector. We have turned down software clients, agencies, property companies and three separate cryptocurrency businesses. Not out of principle in every case — simply because we would have been average at the work, and there is no shortage of agencies willing to be average.

  • Google Ads onlyWe do not run Meta, Amazon or email. Every process we own is built around Shopping feeds, Merchant Center, stock and margin.
  • Profit, not ROASWe will not present return on ad spend as a headline. It ignores cost of goods, delivery and returns, which is to say it ignores your business.
  • Flat fee, alwaysA fixed monthly retainer published in the contract. A percentage of spend rewards an agency for spending your money, and we will not take one.
  • We sit with merchandisingOur weekly call includes your buying and trading team. Bidding decisions made without stock knowledge are guesses.
  • Everything in your nameGoogle Ads account, Merchant Center, feed rules, warehouse tables. Yours from week one, with a full handover if you ever leave.

Enquiries

Before you get in touch

Do you only work in Google Ads?
Yes, and only for retailers. Shopping, Performance Max, Search, YouTube and Demand Gen, plus the Merchant Center and profit reporting that make them accountable. We do not run Meta, Amazon or email marketing, and we will recommend specialists we trust if you need them.
What size of retailer do you work with?
Businesses turning over roughly £2m to £60m online, spending £20,000 to £400,000 a month on Google Ads. Below that a good freelancer is usually better value and we will say so. Above it you probably need an in-house team with us in an advisory role, which we also offer.
Why do you need our cost of goods?
Because without it we are optimising to revenue, and revenue tells you nothing about whether a sale was worth making. Two products at the same price with the same return on ad spend can have wildly different margins, and Smart Bidding cannot tell the difference unless we tell it. We handle the data under NDA, and we can work with margin bands rather than exact figures if that is easier to approve internally.
How are you paid?
A flat monthly retainer based on catalogue size, campaign count and market count, agreed in advance and stated in the contract. We never charge a percentage of ad spend, and we accept no rebates or incentives from Google, from any feed tool, or from any agency partner programme.
Will our revenue go down?
Occasionally, and we will tell you before it does. If a meaningful part of your catalogue is being advertised below true margin, the profitable answer involves selling less of it. We model the expected effect on both revenue and profit before making any change of that size, and the decision is always yours.
Do you work with our existing feed tool?
Yes — we work in Feedonomics, Channable, DataFeedWatch, Shopify's native feed and bespoke pipelines. We have no reseller relationship with any of them and receive no commission for recommending one. Where your current tool cannot do what the account needs, we will say so and explain exactly why.
What is the notice period?
Sixty days after any initial minimum term, which is normally six months because that is roughly how long feed and structural work takes to show its full effect. Handover includes documentation, a full account walkthrough and a call with whoever takes over. Nothing is held back.
