Most Retailers Are Overpaying for Google Shopping

Vast majority of brands and agenices do the same thing. PMAX or Smart Shopping, you lose control over where that money goes. Without a CSS, you pay full click prices. Roasy fixes both: CSS pricing plus external bid automation.

  • No product-level bid control

    Performance Max bundles everything into one campaign. A 2p accessory gets the same bid logic as a £500 product with 40% margin.

  • Opaque reporting

    You cannot see which search terms triggered your ads, which products waste spend, or where Google places your budget across its networks.

  • Algorithms chasing volume, not profit

    Google's bidding claims conversions on branded terms and remarketing audiences you would have won anyway, then charges you for the privilege.

Google Shopping Without a CSS
  • Full-price CPCs (no CSS margin)
  • Black-box bid decisions via PMAX
  • Identical CPCs for £2 and £500 products
  • No search term visibility
  • Google controls the pace and the pricing
Roasy CSS + Bid Automation
  • CSS margin: up to 20% lower CPCs
  • 60+ targeted campaigns per account
  • SKU-level bid automation via API
  • Price-band bidding (CPC tied to margin)
  • Full search term and device data

Every Search Has a Different Value. We Bid Accordingly.

When someone searches for your exact product name, that query is worth far more than a generic browse. Our automation classifies search intent in real time and assigns bids proportionally. High-intent queries get aggressive bids. Generic browsers cost you pennies.

This is what Google's automated bidding cannot do: apply your margin knowledge to every query, for every product, continuously.

What You Get From a CSS That Actually Manages Your Bids

Most CSS providers just switch your account and collect their margin. We run your campaigns through the Google Ads API with external bid automation on top of the CSS pricing advantage.

Intent-Tiered Structures

We split your account into generic catch-all campaigns at minimum bids and product-specific campaigns at higher bids. When someone searches for your exact SKU, they hit the high-bid campaign. Generic browsers cost pennies.

Price-Aware Bid Automation

Our scripts map every SKU against its retail price and set bids proportionally. From 2p on sub-£1 accessories to 50p on £500+ premium lines. Seven price bands, each with its own CPC range, updated automatically.

Feed Quality Auditing

Placeholder prices, missing availability fields, broken product types: these silent errors tank your impression share. Our feed audit catches them before Google buries your products.

Device & Schedule Modifiers

28 schedule rules per campaign, tuned to when your customers buy rather than browse. Mobile bid adjustments based on actual device-level ROAS data, not guesswork.

Audience Layering

Previous purchasers get a 40% bid boost. All site visitors get +15%. These observation layers push budget towards people who know your brand, without surrendering bid control.

Seasonal ROAS Rebidding

Each quarter we pull last year's data for the same period and adjust bids per SKU. A product that delivered 22,000x ROAS last spring gets a meaningful increase. One that spent £40 and sold nothing gets cut.

How Roasy Compares to Google's Native Bidding

These numbers come from real accounts running both approaches side by side. Same products, same budgets, different bid management.

Built for Automated Control

Every campaign follows a strict naming convention: [Account][Strategy][Category]. Ad groups carry their SKU in the name so reporting rolls up cleanly from product to category to account level.

Generic campaigns act as a low-bid safety net. Product campaigns carry the budget. Our automation manages the bids across all of them continuously.

Your Feed Is Half the Battle

We have found accounts where 13 products carried £1 placeholder prices while the real price was over £1,000. Google treated those items as low-value inventory and buried them. Nobody noticed because PMAX hid the data.

Our automation compares every SKU's feed price against its CPC, flags anomalies, and generates bid recommendations broken down by price band.

  • Automated feed-vs-CPC mismatch detection
  • Price-band analysis across 7 tiers
  • Placeholder and missing-field alerts
  • Bulk API bid updates, not manual UI clicks

API-Driven, Not Click-by-Click

A single bulk operation updates 773 ad group modifiers, applies 28 schedule rules across 67 campaigns, and layers audience bid adjustments on every product group. All in one pass.

When spring arrives, we pull last year's seasonal data, generate a bid adjustment plan, run it through the API, and your account is tuned for the season before your competitors have opened their spreadsheets.

  • Bulk API mutations, 1,000+ operations per call
  • Seasonal bid plans from historical ROAS
  • Batch operations that respect API quotas
  • Full audit trail for every change
