Connect Shopify to Google Merchant Center and check conversions

The Google & YouTube channel connects Shopify with Merchant Center to synchronise products. Google Ads and Google Analytics are separate connections within the same environment: publishing a catalogue does not prove conversion measurement is correct.

Before creating new accounts, identify existing business accounts and who has access. Duplicate accounts or an incorrect domain claim can complicate a previously functioning catalogue.

Which account serves each task?

The channel connection guide explains these options. Connect those you need; they are not all mandatory for the same objective.

Check store requirements and access

• A public, functioning website with valid payment methods.
• Visible contact details, policies and terms.
• A domain associated with the correct account.
• Sufficient Google account permissions.
• Consistent countries, currencies and delivery conditions.

Review channel requirements. If another Merchant Center account claims the domain, investigate before transferring it: existing feeds may be affected.

Connect and review a sample

1. Install the official Google & YouTube channel and connect the authorised account.
2. Select the correct Merchant Center, or create one if none exists.
3. Complete outstanding verifications and requirements.
4. Review countries, languages and shipping settings.
5. Check synchronised products and their statuses.

Start with representative products. Identify specific warnings and rejections, correct the source and check the new status. Synchronisation and reviews need not complete immediately or within one fixed timeframe for every account.

GTINs, brand and product data

Use real identifiers where they exist. Do not invent codes or mark a product custom-made to bypass an error. Google explains identifier_exists for items genuinely lacking certain identifiers.

Also check variants, image, price and availability. A landing page showing a different currency or option remains inconsistent even if every feed field is filled.

Shipping and returns

The channel offers sync or manual options according to supported operations. It is incorrect to claim shipping always needs manual entry in Merchant Center.

Compare example destinations and baskets between Google and checkout. Special rates, profiles or complex rules may need specific review. Keep return conditions clear and current.

Enhanced conversions: what they do and do not resolve

Google Ads enhanced conversions supplement measurement with hashed first-party data. Hashing does not automatically make data anonymous or remove consent and privacy requirements.

Review channel options and conversion action settings. Before enabling another route, inventory existing tags, pixels and apps to avoid counting purchases twice.

Validate a test order

1. Check behaviour according to consent.
2. Complete a controlled purchase with known currency and value.
3. Verify the action and parameters match the order.
4. Check possible duplicates across integrations.
5. Document windows and criteria before comparing reports.

Shopify, Ads and Analytics may show different figures because of attribution and processing rules. A difference alone does not prove an integration is broken.

What to prioritise next

Correct rejected products and contradictory data before expanding campaigns. For search surfaces, see Google Shopping changes; for Meta signals, Pixel and Conversions API covers another measurement integration.
