Pet Supplies
Pet food, toys and prescription lines are three different businesses.
One is a subscription with months of payback. One is an impulse purchase with thin margin. One is a protected line you must not lose. A single ROAS target manages none of them well.
Why this changes the advertising decision
What is different here isn't the channel. It's the economics underneath it.
Food is a subscription in disguise
The first bag is not the transaction. Acquisition cost has to be judged against the reorder behaviour you can actually observe.
Accessories carry thin margin and heavy weight
Low-value items with real shipping cost can lose money at the exact moment the platform reports a conversion.
Prescription and specialist lines are defensive
These customers are loyal and hard to replace. The job is retention and availability, not aggressive acquisition.
Animal size and life stage fragment demand
Variant-level demand is specific. Product-level performance hides which variants are actually carrying the range.
One product, one decision
The decision looks like this.
Illustrative example. Not a client result.
Grain-free dry food, 12kg
- Contribution, first order
- Slight
- Reorder cycle
- Roughly six weeks
- Cohort value
- Measured, not modelled
- Stock cover
- Steady
What changed
Observed reorder behaviour across real cohorts.
The first bag barely pays. The customer does, repeatedly, and that is the number the bid should answer to.
Nothing here happens automatically. The data flags the change; the job change is a decision we make with you.
What we do about it
The execution follows the economics, not the other way round.
Reorder behaviour sets the acquisition price
Cohort value comes from your own order history over a stated window, not a platform projection.
Small heavy items are checked after shipping
Contribution includes real fulfilment cost, so low-value accessories are not scaled into a loss.
Protected lines are defended, not pushed
Prescription and specialist ranges run to hold position and availability rather than chase volume.

The Method - BOI®
How BOI® applies here.
The problem
Subscription food, one-off toys and prescription items are three different P&L lines in one catalogue.
The BOI® answer
Food runs as Scale against measured reorder behaviour. Accessories run as Profit. Prescription runs as Protect.
Next step
We'll tell you what your account is doing to your pet supplies margin.
A commercial review reads your account against your own product economics, and tells you where the next pound should go. Brands we work with typically spend around £10k a month on Google Ads, but that is guidance, not a gate. If you are below it and the question is real, ask anyway.
