BUILT FOR E-COMMERCE
Shopping ads start with eligible products, accurate data and commercial priorities.
Google Shopping uses product data to match inventory with relevant searches. Weak titles, missing GTINs where applicable, price or availability mismatches and Merchant Center disapprovals can limit eligible coverage. I review these alongside product margins, stock levels, target countries and purchase-value reporting before recommending campaign changes.
Shopify stores
Review the Shopify–Google product sync, item IDs, variants, availability, landing-page consistency, Merchant Center diagnostics and purchase reporting. For a Shopify-specific PPC strategy, see my Shopify PPC management service.
WooCommerce retailers
Check WooCommerce feed generation, product titles and categories, price/availability updates, GTIN or brand attributes where relevant, Merchant Center policies and purchase values.
Existing advertisers
Audit existing Standard Shopping and Performance Max campaigns, eligible product coverage, product-level performance, bidding goals, budget allocation and the reliability of attributed conversion value.
New product advertisers
Validate product eligibility, shipping and returns settings, target country, landing pages and purchase measurement before selecting an initial Shopping campaign structure and test budget.
WHAT’S INCLUDED
What effective Google Shopping management actually involves.
Google Shopping management
Plan Standard Shopping inventory segmentation using product categories, brands, custom labels or commercial priorities where appropriate. Review product-group performance, search terms, negatives, bids and budget distribution based on the available controls.
Performance Max support
Assess whether Performance Max fits the store’s objectives and data quality. Review listing groups, product coverage, asset-group themes, bidding targets and available reporting. Automation is not a substitute for clean feed data or accurate purchase values.
Merchant Center & feeds
Investigate disapprovals and limited visibility caused by mismatched price or availability, missing required attributes, policy issues, shipping settings, return information or landing-page inconsistencies. Prioritize fixes affecting important SKUs.
Purchase measurement
Review purchase event values, transaction IDs, currency and possible duplicate conversions. Where store data is available, compare Google Ads attributed value with actual orders, refunds and margins; reported ROAS is not the same as net profit.

COMMON QUESTIONS
Before we work together
Standard Shopping or Performance Max: which fits my store?
Standard Shopping provides more direct control over product groups and campaign structure. Performance Max uses automation across eligible Google inventory. The right choice depends on feed quality, product margins, business goals, conversion data and required control.
Can you audit an existing Google Shopping account?
Yes. I review Merchant Center diagnostics, feed attributes, product coverage, Standard Shopping or Performance Max structure, bidding, search insights where available, purchase-value reporting and commercial priorities.
What causes Google Merchant Center product disapprovals?
Product issues can arise from price or availability mismatches, missing identifiers or other required attributes, landing-page problems, shipping discrepancies or policy restrictions. I check the actual diagnostics before proposing a fix.
Does a strong Shopping ROAS mean the store is profitable?
Not necessarily. Google Ads ROAS uses attributed conversion value divided by advertising cost; it does not subtract cost of goods, shipping, returns, discounts or operating costs. Performance depends on the market, products, competition and measurement quality.
