Google Shopping Feed Management | NetAmplify by Lengow

Why Google Shopping Needs Intelligent Feed Management

Google Shopping is one of the most competitive ad formats in e‑commerce, where data gaps (missing GTINs, low‑quality images, or outdated pricing) can sabotage performance. Common hurdles include:

Product disapprovals due to incomplete or mis‑formatted attributes
Reduced visibility from low‑relevance titles or missing localization
Manual updates that slow time‑to‑market
Ads running for out‑of‑stock inventory, risking ad spend waste

NetAmplify by Lengow offers pro‑grade feed governance that ensures compliance, freshness, and optimization – resulting in more approvals, higher click‑through rates, and improved ROAS across markets.

What NetAmplify does for Google Shopping

Google Feed Readiness & Compliance

Get step-by-step, in-product guidance to structure your catalogue for Google Merchant Center – covering required attributes, formatting (GTINs, price/availability), category mapping, and image rules. Pre-publish checks flag gaps and explain how to fix them so your feeds pass compliance smoothly.

Feed Localisation & Multi‑Market Support

Generate feeds across 70+ markets. Tailor pricing, shipping, and copy to each country’s rules and conventions in one streamlined workflow.

Local Ads Feed Readiness

Centralise and normalise store-level product data – catalogue, inventory, prices, and store IDs – into a per-store × SKU structure. Apply category/attribute mapping and validations so availability, price and identifiers are clean and ready for local ad use.

Title & Attribute Enrichment

Use dynamic rules to enhance titles and descriptions, for example: “Nike Pegasus 39 → Nike Pegasus 39 Men’s Running Shoes – Lightweight, Size 42” – improving relevance, CTR and search intent alignment.

Google Merchant Center & Ads Integration

Feed distributions are directly submitted to Merchant Center, supporting Shopping, Performance Max, and dynamic remarketing campaigns, with live syncing that keeps ads up-to-date across price, inventory, and promotions.

Google LIA & RAAP Activation

Generate and maintain Google-compliant local feeds (availability, price, pickup options, store codes) and push them to Merchant Center for Local Inventory Ads (LIA) and RAAP. Pre-publish checks and high-frequency updates reduce disapprovals and keep every store eligible.

Who Should Use This

This solution is built for:

Retailers running Google Shopping and Performance Max in multiple countries
Brands managing large SKU catalogs with frequent product updates
Agencies seeking scalable feed infrastructure without dev overhead
Teams using dynamic promotions or localized campaigns with inventory-aware logic

How does NetAmplify improve Google Shopping feed approval rates for large catalogues?

Approval rates in Google Merchant Center often drop due to incomplete or non-compliant data: missing GTINs, invalid image URLs, incorrect availability fields, or policy violations. NetAmplify automates the detection and correction of these issues using a built-in diagnostics engine, real-time error alerts, and rule-based data enhancement.

For example, L’Oréal Luxe leveraged these capabilities to manage 11 brand catalogs across 80+ countries, significantly reducing disapprovals and achieving faster go-to-market velocity. Brands with long-tail SKUs often see up to 38% improvement in approval rates within the first optimisation cycle.

How does title and attribute enrichment directly impact campaign performance?

Generic or truncated product titles often lead to poor ad placement and low click-through rates (CTR) on Google Shopping. With NetAmplify, users can build enrichment rules that dynamically inject brand, category, size, gender, or even seasonal keywords into product titles and descriptions – without altering the source catalog.

Kiehl’s Nordic used this technique to reformat hundreds of SKUs with high-conversion phrasing and accurate pricing tags, which led to a +41% CTR increase during their Black Week campaign, despite running with a smaller budget.

How does NetAmplify support Performance Max and Dynamic Remarketing campaigns beyond standard Shopping feeds?

NetAmplify integrates directly with Google Merchant Center and Google Ads, enabling automatic syncing not only for standard Shopping feeds but also for Performance Max (PMax) and Dynamic Remarketing campaigns. The platform ensures that SKUs promoted across these formats are synchronised with real-time inventory, promotional calendars, and custom audience segments.

L’Oréal Luxe benefited from this by using distinct feeds for upper- and mid-funnel targeting, with asset groups tied to seasonal launches and hero SKUs. Combined with enriched titles and high-quality visuals, this approach led to a 3x revenue lift on Shopping and a +20% increase in average order value.

What are the benefits of managing Google Shopping feeds across multiple countries from a single platform?

Scaling Google Shopping across borders introduces complex localisation challenges: varying currencies, tax rules, shipping costs, language translations, and pricing models. NetAmplify simplifies this by allowing marketers to generate country-specific feeds from a master source, using conditional rules and localised content blocks.

Wethenew used this feature to expand into four new markets, customizing feeds in 40,000 SKUs with hourly updates to price, availability, and competitive tags – automatically. The result was a streamlined workflow and a 30% uplift in ROAS through more relevant, localised ad content.
