Google Shopping Ads That Sell Products, Not Just Show Them

The product feed is the single most important performance lever in Google Shopping. We audit every feed attribute — title, description, product_type, google_product_category, GTIN, MPN, brand, color, size, material, condition, availability, and price — and optimise each for query matching accuracy and data completeness.

Product titles are restructured to front-load the highest-value keywords buyers actually search for. Descriptions are expanded with relevant search terms, material details, and use-case language. Custom labels are applied to segment products by margin, price tier, seasonality, and performance history — enabling smarter campaign segmentation downstream.

Google Merchant Center is the backend infrastructure that powers all Shopping and Performance Max campaigns. Without a healthy Merchant Center account, no campaign optimisation produces reliable results. We manage your Merchant Center account on an ongoing basis — monitoring feed health, resolving disapprovals, and maintaining data quality standards.

Common disapproval causes include price mismatches between the feed and the landing page, image quality issues, missing required attributes, policy violations, and shipping configuration errors. We monitor the Merchant Center diagnostics dashboard weekly and resolve disapprovals within 24–48 hours of identification. Feed re-submission and cache clearing after fixes is included.

Running all products in one "All Products" campaign is the most common structural mistake in Google Shopping. When high-ROAS products, low-margin clearance items, and new untested products all share a campaign, Smart Bidding receives mixed signals and budget allocation becomes inefficient.

We segment Shopping campaigns using custom labels and campaign priorities. High-performing products with strong ROAS history get dedicated campaigns with tROAS targets. New or unproven products are isolated in lower-priority campaigns with Maximise Conversion Value to accumulate data without burning budget from profitable segments. Seasonal and promotional products get their own campaigns that can be turned on and off independently.

In 2026, most Google Shopping accounts need a considered approach to the relationship between Standard Shopping campaigns and Performance Max. Standard Shopping gives you control — you can see exactly which products are serving, which search terms are triggering them, and you can adjust bids at the product group level. Performance Max gives you reach — your product feed is served across Search, Shopping, Display, YouTube, Gmail, and Maps.

We build a campaign architecture where Standard Shopping captures core, high-intent product search traffic with maximum control, while a Performance Max campaign — with a well-structured asset group and audience signals — captures incremental demand across other Google surfaces. The two campaigns are structured to avoid cannibalisation, with campaign priorities and budget guardrails managing which one serves for which query intent.

Shopping bidding strategy selection and progression follows a data-driven sequence. Starting tROAS too early — before sufficient conversion data exists — is one of the most common reasons Shopping campaigns underperform or stop serving. We manage the full bidding lifecycle: from early data collection through to mature tROAS optimisation.

The progression follows three stages: first, Maximise Conversion Value with no ROAS target to collect clean conversion data without constraining reach. Second, Maximise Conversion Value with a soft ROAS floor once 30+ monthly conversions are accumulating. Third, Target ROAS at a level at or below the account's achieved ROAS, incrementally raised as the campaign demonstrates it can hold performance at higher targets.

Shopping campaigns do serve from real search queries — and the search terms report shows you exactly which queries are triggering your products. Without regular search term analysis and negative keyword management, shopping budgets leak into competitor brand searches, irrelevant category terms, and informational queries that generate clicks but no purchases.

We review the search terms report weekly for every shopping campaign, categorising queries by relevance, intent, and conversion performance. Negative keywords are applied at the campaign level and account level. We maintain a shopping-specific negative keyword list covering the most common sources of irrelevant traffic — including "free," "used," competitor brand names, wrong-category modifiers, and navigational terms.
