The problem

Google is spending your budget.
You just can't see where it's going wrong.

When you run Shopping or Performance Max, Google decides which products to show — and it doesn't always pick the right ones. Without a structured feed, your budget spreads thin. Your best products get lost in the noise. Products that have never converted in 18 months keep getting impressions.

The fix is a labelled product feed. And the same classified feed that improves your Google Shopping performance also feeds directly into Microsoft Shopping, Meta, TikTok, Pinterest, and comparison engines — with minimal extra work.

The framework

Six performance tiers. Every product gets a label.

We classify every product in a client's feed into one of six tiers, based on real click and conversion data. Nothing falls into an unmanaged catch-all. Every product gets a deliberate treatment.

Tier What it means Classification criteria Data window
⭐ Hero Proven revenue drivers. These get priority budget and aggressive bidding. Conversions > 4 AND ROAS > 5× 60-day
🚨 Villain Click magnets that never convert. Actively draining budget. Clicks > 25 AND Conversions = 0 30-day
🤝 Sidekick Converting and growing — on the path to hero status. Conversions > 1 AND ROAS > 2× 30-day
📈 Promising Early positive signals — worth investment to develop. Conversions < 4, ROAS > 1.5×, Clicks > 15 30-day
💀 Zombie Invisible to Google. Investigate titles, pricing, and eligibility. Clicks = 0 30-day
🏳 Flagged Mixed signals. Review before campaign inclusion. Everything else —
The process

Five steps. Under an hour. Done with AI.

You don't need a developer or a data team. You need your Google Ads export, your GMC feed, and Claude. The guide walks you through every step — including the exact prompt to paste in.

Step 1
Export your Shopping data from Google Ads
Reports → Shopping → Products. Last 60 days. Download as CSV with clicks, conversions, cost, and conversion value.
Step 2
Download your current GMC product feed
Your master product list from Google Merchant Centre — every product eligible to serve on Shopping.
Step 3
Upload both files to Claude and run the prompt
The guide includes the exact classification prompt. Claude returns a fully labelled product table within minutes.
Step 4
Build your supplemental feed
A two-column CSV — Product ID and label — uploaded to GMC as a supplemental feed, mapped to custom_label_0.
Step 5
Restructure your Shopping campaigns around the tiers
Heroes get priority budget. Villains get excluded. Sidekicks and Promising get their own group. The guide explains exactly how to set this up in Google Ads.
Beyond Google

One classified feed. Multiple channels.

The same labelled feed that improves your Google Shopping campaigns feeds directly into every major shopping platform. One piece of work. Multiplied across channels.

Microsoft Shopping
Direct GMC import. Often cheaper and less competitive — particularly effective for B2B and older demographics.
Meta Advantage+ Catalogue
Your Heroes become the seed for Dynamic Product Ads. Meta performs best when fed high-converting product data — not your whole catalogue.
TikTok Shop
Hero products are natural candidates for TikTok Shopping ads and creator campaigns. A clean, accurate feed is the prerequisite for the catalogue sync.
Pinterest Shopping
Often overlooked. Particularly effective for home, fashion, and gift brands. Feed-based campaigns need minimal extra setup.
Comparison Shopping Engines
Google CSS, Idealo, PriceRunner, and others. A clean, optimised feed improves competitive position across all comparison placements.
Organic Shopping
Google's free Shopping listings use your GMC feed directly. Fixes made for paid Shopping improve your organic visibility at the same time — at no extra cost.

Which channels make sense depends on your category, audience, and margin profile. We advise every brand individually — and only recommend channels we believe will deliver a positive return.

We only earn when you do.

Questions

No doubts left standing

What's in the guide exactly?
The guide covers: the six performance tiers and what each means, the exact criteria and data windows we use to classify products, a step-by-step process for running the classification in Claude, the prompt to copy and paste, how to build your supplemental feed, how to restructure your campaigns around the labels, and how the same feed can be extended to other channels.
Do I need to be technical to use this?
No. You need access to your Google Ads account and Google Merchant Centre, and a free Claude account at claude.ai. The guide includes the exact prompt to use — you paste it in, upload your two CSV files, and Claude does the classification. No code required.
What platforms does this work with?
Any platform that generates a Google Merchant Centre feed — Shopify, WooCommerce, Magento, BigCommerce, and custom builds alike. If your products are in GMC, this works for you.
How often should I re-run the classification?
We recommend monthly as a minimum, or after any significant product range or pricing change. Product performance shifts over time — a hero today can become a villain in 90 days in a competitive category. The guide covers how to make this a routine process.
What does Positive Sparks do, and how does the commission model work?
We're a Google Ads agency specialising in ecommerce — Shopping, PMax, and search, with Meta, Microsoft, TikTok, and affiliate as complementary channels. For established brands, we work on pure commission from day one — a percentage of the revenue we drive, with no retainer. For brands newer to advertising, we use a fair minimum fee structure that transitions to full commission as performance scales. Either way, our income is tied directly to your results.
