How a Comparison Shopping Service fits Google Shopping
A CSS provides the comparison-shopping route used by eligible Shopping ads. Gander is the CSS owned by Clean Digital. The account review separates the potential auction benefit from the work needed in Merchant Center, the product feed and campaign structure.
If the account also needs campaign or feed work, our Google Shopping management service covers campaign structure, while Merchant Center management and shopping feed optimisation cover eligibility and product data.
Existing account review
We check the current Google Ads and Merchant Center setup before recommending a switch. The implementation plan records the changes required and how serving will be verified.
Gander service terms
Eligibility, current fees, supported markets, implementation timing and support scope are confirmed for the account before setup begins.
How a Gander account review works
The review establishes the account facts first. No change is made until eligibility, terms and implementation requirements have been agreed.
Review the account
Share the current Shopping setup, target markets and approximate monthly spend. We check Merchant Center status, feed readiness and campaign structure.
Confirm eligibility and terms
We confirm whether Gander is suitable, the expected commercial impact, current fees, support scope and the account changes required.
Implement and verify
After approval, we make the agreed change and check that the Shopping campaigns continue to serve as expected.
What you receive before deciding
The decision should be based on the account, the current Gander terms and the expected net impact after fees.
Account-specific cost assessment
We estimate the potential CSS effect from the account setup and current Shopping spend. The estimate is recorded as a forecast rather than a guaranteed saving.
Implementation plan
The plan records the Merchant Center and Google Ads changes required, who owns each step and how campaign serving will be checked after implementation.
Current commercial terms
Fees, contract terms, supported markets, implementation timing and support scope are confirmed before the account proceeds.
What is checked before a CSS switch
The change register gives the account owner a clear record of the current setup, the approved changes and the checks required after implementation.
| Account area | Before implementation | After approval |
|---|---|---|
| CSS route | The review records the current Shopping route and confirms whether the account is eligible for Gander. | The agreed CSS change is implemented and checked against the approved account plan. |
| Google Ads campaigns | Campaign structure, bidding and conversion tracking are checked for dependencies before implementation. | Any campaign changes are made only when they are part of the agreed plan. Serving is checked afterwards. |
| Merchant Center and feed | Account status, target markets, feed source and Google Ads links are reviewed for readiness. | Required account and feed changes are documented, assigned and verified. |
| Commercial terms | Current fees, support scope, contract terms and implementation timing are supplied for review. | The account proceeds on the agreed terms, with no reliance on a generic saving or timing claim. |
