Shopping Feeds & Marketplace Ads
Power profitable product advertising with accurate, optimised product data.
Shopping Ads and marketplace advertising don’t succeed because of bids alone.
They succeed because of clean, structured, optimised product data.
Many businesses struggle with Shopping and Marketplace Ads due to poor feed quality — disapproved products, inaccurate pricing, stock mismatches, low visibility and declining ROAS. These issues are rarely caused by the ad platform itself. They are almost always data problems.
At StreamMarket, we treat Shopping Feeds & Marketplace Ads as a performance channel powered by data. We design, optimise and manage product feeds that fuel high-performing campaigns across Google Shopping and major marketplaces — ensuring your products appear correctly, competitively and profitably.
This is not just feed setup.
This is product advertising infrastructure.
What Shopping Feeds & Marketplace Ads Really Mean
A shopping feed is the structured product data that platforms use to:
- Understand what you sell
- Decide when and where to show your products
- Match products to search intent
- Calculate relevance and quality
If your feed is inaccurate or poorly structured, your ads will underperform — regardless of budget.
A strong shopping feed ensures:
- Higher visibility
- Better click-through rates
- Improved conversion rates
- Stronger ROAS
That’s why feeds must work hand-in-hand with Paid Marketing, not separately from it.
Why Product Data Quality Drives Ad Performance
Product advertising platforms are data-driven.
Well-optimised feeds:
- Improve product relevance
- Reduce disapprovals and errors
- Protect margins through accurate pricing
- Prevent overselling with real-time availability
- Enable scalable multi-channel advertising
Feed quality directly influences campaign efficiency.
Shopping Feed Management & Optimisation
We build and manage feeds designed for scale and performance.
Feed Optimisation Includes
- Product title and description optimisation
- Category and taxonomy alignment
- Attribute enrichment (brand, GTIN, condition, variants)
- Image optimisation and compliance
- Pricing accuracy and promotional rules
- Availability and stock handling
- Error prevention and monitoring
Feeds are continuously refined — not treated as a one-time setup.
Google Shopping & Performance Max
We enable and optimise feeds for:
- Google Shopping campaigns
- Performance Max product feeds
- Merchant Centre compliance
- Promotional and seasonal campaigns
Feed structure directly influences:
- Impression share
- Product matching
- Automated bidding performance
Shopping Ads work best when combined with Paid Marketing strategy and ongoing optimisation.
Marketplace Advertising Enablement
Marketplaces are increasingly pay-to-play.
We prepare and optimise feeds to support:
- Sponsored Product Ads
- Sponsored Brand campaigns
- Marketplace-specific data requirements
- Category and search visibility
This work integrates naturally with Sell on Marketplaces, ensuring consistency across listings and ads.
Stock, Pricing & Availability Sync
Inaccurate stock is one of the biggest causes of:
- Ad disapprovals
- Poor customer experience
- Lost revenue
We design feed systems that:
- Sync stock in near real-time
- Reflect accurate pricing and promotions
- Protect margins and availability
- Scale across multiple channels
This is often supported by Global Stock Management and backend system alignment.
Multi-Channel Feed Architecture
Growing brands sell across multiple channels — not just one.
We create feed architectures that:
- Use a single source of truth
- Publish to multiple channels simultaneously
- Support Google, marketplaces and social commerce
- Scale without duplication or manual work
This is typically enabled through API & Third-Party Integrations, ensuring data flows reliably between systems.
Product-Level Reporting & ROAS Optimisation
Product advertising success is measurable.
We track:
- Product-level ROAS
- Channel performance
- Revenue contribution by feed segment
- Error impact on performance
- Stock and pricing-related losses
Insights are delivered through Advanced Reporting, helping you understand which products truly drive growth.
