About this tool
Are you bidding the same on products that sell like crazy and products that get zero clicks? This tool automatically labels every product in your Google Merchant Center based on real performance data — so you can bid smarter, not harder.
Connect your Google Ads account, and the app classifies each product into one of five categories: top performer, clicks but no sales, impressions but no clicks, zombie (no impressions at all), or unlabeled. Labels are written to a Google Sheet that serves as a Merchant Center supplemental feed via custom_label_4.
Use these labels in your Google Ads campaigns to set different bids, exclude zombie products, or create dedicated campaigns for your best sellers. The labeling runs via a Google Ads Script that you copy from the dashboard — no API setup, no coding required.
Supports multiple Merchant Center accounts under one subscription — ideal for agencies managing several clients.

Frequently asked questions
How do I get access after payment?
Immediately after payment you receive an email with a magic link. Click it to open the dashboard and start setting up your accounts.
How does the labeling work?
You copy a Google Ads Script from the dashboard into your Google Ads account. The script analyzes product performance data, assigns labels, and writes them to a Google Sheet. That sheet is connected to Merchant Center as a supplemental feed.
What labels are assigned?
Products are classified as: top_performer (high clicks + sales), clicks_no_sales (clicks but no conversions), impressions_no_clicks (shown but not clicked), zombie (zero impressions), or unlabeled (new or insufficient data).
Can I customize the labeling thresholds?
Yes. You can adjust the performance thresholds that determine when a product is considered a top performer, zombie, etc.
How do I use the labels in Google Ads?
Once the supplemental feed is connected, custom_label_4 appears in your Shopping campaigns. Use it to set bid adjustments, create product groups, or exclude underperforming segments.
Can I label products across multiple accounts?
Yes. You can connect multiple Merchant Center accounts and label products in each one separately.
