The Zombie SKU Report: The Hidden CTR Killer In Google Shopping

Why 60% of your product catalog probably received zero clicks last month—and the systematic framework to fix it.

Legacy feeds "leak" budget by bidding on keywords that never convert.

Google suppresses products with <0.5% CTR to preserve their own UX.

Resurrection through title enrichment and specific attribute mapping.

A Zombie SKU is any active product in your Google Merchant Center catalog that fails to receive click traffic over a standard 30-day window. While it remains approved, indexed, and technically "ready to serve," the search algorithm refuses to allocate meaningful impressions to it.

In the era of Performance Max (PMax), where Google relies on artificial intelligence to distribute budget across channels, these dormant products damage your account's algorithmic health. Google's primary motive is to maximize revenue from ad clicks. If a listing fails to convert impressions to clicks, the algorithm suppresses it to protect the search engine's yield-per-impression.
