How to Read Your Zombie Products Report

Your audit identifies products burning budget without a single sale, margin-destroying converters, and feed quality issues. This guide explains every metric and the exact actions to take. The PDF skeleton on the right highlights where you are.

The Four Headline KPIs

Page 1 — the scale and velocity of the zombie problem

These KPIs quantify the zombie problem in four dimensions: total waste, product count, daily burn rate, and waste as a share of total Shopping spend. The daily burn rate is the urgency metric — it translates total waste into money lost per day, making the cost of inaction tangible.

Zombie Count

Products with zero sales

Products meeting all three zombie conditions: zero units sold, at least 20 clicks (meaningful traffic), and cost above the currency-adaptive threshold (account avg CPC × 20 clicks). The threshold adapts to your account's cost structure — a ₹2 CPC account uses a different floor than a $5 CPC account.

Daily Zombie Burn

Money Lost Per Day

Total zombie waste divided by the reporting period in days. This is the daily cost of doing nothing — every day you delay exclusions, this amount leaves your account with zero return.

Multiply by 30 to see your monthly exposure. This is the number that gets stakeholders to act.

Why 20 clicks, not 10 or 50?

Statistical Threshold

The 20-click minimum prevents false positives from products that accidentally received minimal spend. A product with 20+ clicks and zero sales is not statistical noise — it has had enough opportunity to convert and failed.

S2

Top Zombie Products by Wasted Cost

Page 1 — the products burning the most money

The zombie products ranked by wasted cost — the absolute dollar amount each product has consumed with zero sales. Focus on the dollar figure, not click count. A product with 50 clicks at $2 CPC wastes $100. A product with 25 clicks at $8 CPC wastes $200.

Top-ranked zombies

Exclude First

Start from the top. Each product you exclude at the top of this list recovers more budget than excluding ten products at the bottom. Work top-down for maximum impact.

Exclude these products from your Shopping/PMax campaigns via product-level exclusions in your asset group listing groups. Do not pause the entire campaign — just exclude the zombie SKUs.

S3

Zombie Category Concentration

Page 1 — which product categories are graveyards

Zombie count and wasted cost grouped by product category. If one category dominates, the fix is category-level (exclude the category or fix the product feed for that category). If zombies are spread evenly, the problem is account-structural.

One category with 50%+ of zombie waste

Category Problem

This category's products systematically fail to convert. The issue may be pricing, product-market fit, or feed data quality for this category specifically — not your overall Shopping strategy.

Investigate this category independently: check product titles, images, pricing competitiveness, and whether the products are available and in stock.

S4

Zombie Spend Trend

Page 1 — is the problem growing or stable?

Daily spend on zombie products over the reporting period. A rising trend means the algorithm is allocating more budget to products that have never sold — the zombie problem is actively growing. A flat trend is concerning but manageable.

Rising trend

Growing Problem

The algorithm continues to invest in products with zero historical sales. Without exclusions, this trend compounds — the algorithm has no negative signal to learn from because these products generate clicks (which the algorithm interprets as interest).

Implement exclusions immediately. The trend will not self-correct because the algorithm sees clicks as positive signal even when no sales follow.

Page 2Margin Killers
S5

Margin Eaters (Converting but Unprofitable)

Page 2 — products that sell well but destroy profit

Products where ad spend exceeds gross profit — they convert (different from zombies) but every sale loses money after ad costs. These are more dangerous than zombies because they look like winners in the dashboard. The algorithm will continue scaling them because it optimizes for conversions, not profit.

Negative net profit after ads

Loss Per Sale

Every unit sold costs more to advertise than the gross profit it generates. Selling more of this product at current ad costs makes you poorer, not richer.

Set a minimum ROAS target above break-even for campaigns containing these products, or exclude them from paid advertising and sell through organic/email channels only.

S6

Days to Zombie (Burn Velocity)

Page 2 — how fast does each product waste money

Each zombie product's total waste, days active with spend, and daily burn rate. Products with high daily burn rates are the most urgent exclusion candidates — they waste the most per day of inaction. Calendar days burning shows how long the product has been draining budget.

High daily burn rate

Urgent

This product wastes more per day than most other zombies waste in a week. Every day of delay costs disproportionately.

Exclude immediately — this product alone may represent a meaningful fraction of your total daily waste.

S7

Profit Distribution

Page 2 — how products spread across profit tiers

All products with 5+ clicks bucketed by net profit tier: Highly Profitable, Marginally Profitable, Break Even, Slight Loss, and Significant Loss. A thin profitable slice signals a systemic margin problem across the catalog — not isolated zombie exceptions.

Significant Loss tier larger than Highly Profitable

Catalog Problem

More products destroy profit than generate it. The problem isn't a few bad SKUs — it's a structural issue with your product-level advertising economics. COGS may be too high, prices too low, or CPCs too expensive for your margin structure.

Consider whether product-level advertising is viable for your catalog's margin structure. Some products may only be profitable through organic channels.

S8

Revenue vs Profit Leaders

Page 2 — the products that trick your dashboard

Two lists: Top Revenue products and Top Profit products. When these lists don't overlap, your account is optimizing for the wrong metric. A high-revenue, low-margin product looks great in the Ads dashboard but may generate less actual profit than a lower-revenue product with better margins.

Products in revenue top 5 but not profit top 5

Revenue ≠ Profit

The algorithm pushes budget toward these because it sees revenue, not margin. Your dashboard celebrates them, but your bank account doesn't.

Set differentiated ROAS targets by product category. High-margin products can tolerate lower ROAS targets. Low-margin products need higher ROAS floors.

Page 3Feed Health
S9

Feed Health Summary

Page 3 — is your product data causing the zombie problem?

A structural health check on your product feed: missing categories, missing brands, conversion coverage percentage, and zero-conversion products with 20+ clicks. Products without category or brand attributes are invisible to Google's product taxonomy — the algorithm can't match them to relevant audiences.

Missing Category or Brand

Feed Gap

Products without these attributes get lower Shopping placement quality. Google can't match them to relevant queries or audiences, so they either get no impressions or get shown to the wrong people.

Update your Merchant Center feed to include category and brand for every product. This is a feed management fix, not a Google Ads fix.

Conversion Coverage %

The percentage of active products that have generated at least one conversion. Low coverage means a small number of products carry all conversion weight while the rest consume budget without results. Below 20% coverage is a structural problem.

S10

Spend by Category

Page 3 — where your Shopping budget actually goes

Category-level spend, product count, conversions, and ROAS. Check whether your highest-spend categories are your best performers or simply your most expensive problem areas. A category with high spend and low ROAS is a structural waste source.

High spend + low ROAS category

Budget Misallocation

This category absorbs significant budget but returns below-average ROAS. The algorithm funnels spend here because the category has many products (more inventory to bid on), not because it converts well.

Set category-level ROAS targets or exclude the lowest-performing subcategories within this category.

S11

GA4 Confirmed: Zombies Also Failing in Analytics

Page 3 — cross-platform validation

Zombie products cross-referenced with GA4 ecommerce data: cart adds, purchases, and view-to-purchase rate. If GA4 also shows zero purchases for these products, the zombie classification is confirmed across both platforms — there is no attribution gap creating false zombies.

GA4 purchases = 0

Confirmed Dead

Both Google Ads and GA4 agree: this product receives traffic but never sells. The zombie classification is not an artifact of attribution differences — the product genuinely does not convert on any platform.

Exclude with confidence. There is no hidden conversion path that would justify continued ad spend on this product.

GA4 shows cart adds but no purchases

Checkout Friction

Users add this product to cart but don't complete purchase. The product isn't truly dead — it has demand but fails at checkout. This may be a pricing, shipping cost, or checkout UX issue rather than an advertising problem.

Investigate the checkout flow for this product. Check pricing competitiveness, shipping costs, and checkout abandonment data before excluding.

S12

Product Performance Tiers

Page 3 — the ratio determines your strategy

All products classified into four tiers: Converting (has sales), Zombie (20+ clicks, zero sales, above cost threshold), Untested (fewer than 5 clicks), and Low Activity (in between). The ratio of Converting to Zombie determines whether you need to prune (many zombies) or test more (many untested).

Zombie tier > Converting tier

Pruning Problem

More products are proven failures than proven successes. The immediate action is aggressive exclusion of zombies to stop the bleeding, followed by feed optimization to prevent new zombies from forming.

Untested tier is largest

Testing Problem

Most products haven't received enough traffic to evaluate. The algorithm hasn't tested your catalog — budget is concentrated on a small number of products while most languish with near-zero impressions.

Review campaign structure. Products may be excluded by listing group filters, or one asset group may be absorbing all budget.

Exact Exclusion List

Page 4 — the product IDs to exclude today

Every zombie product with its product ID, title, category, wasted cost, and clicks. This is the operational output — copy these product IDs into your Shopping or PMax campaign's listing group exclusions. Each exclusion immediately stops the bleed for that SKU.

Product IDs

Copy & Paste

The product_item_id column matches your Merchant Center feed IDs. Use these to create product-level exclusions in your campaign's listing groups — exclude specific products rather than pausing entire campaigns.

In Google Ads: Campaign → Products → Listing Groups → Add exclusion → Paste product IDs. For PMax: Asset Group → Listing Group → Exclude by Item ID.

S14

Zombie Recovery Summary

Page 4 — what you get back by fixing this

A single-row summary: recoverable budget, percentage of total spend, daily recovery potential, and a simulated conversion gain (if recovered budget were redeployed at your account's average CPA). This is the business case for acting on the exclusion list.

Potential additional conversions

Simulation

If the zombie budget were redirected to your converting products at the account's average CPA, this is how many additional conversions you'd gain. Conservative estimate — it assumes current CPA holds at higher spend.

Use this number to justify the exclusion work to stakeholders. Frame it as: 'Excluding N products recovers $X/month and generates Y additional conversions at no extra cost.'

S15

Zombie Action Split (Fix vs Monitor vs Kill)

Page 4 — not every zombie gets the same treatment

Each zombie classified into three actions: EXCLUDE (proven low demand — remove from ads), FIX FEED (missing brand or category attributes — the product may convert with better feed data), or MONITOR (insufficient data to classify conclusively). Priority ordering tells you what to act on first.

EXCLUDE — Low demand product

No Fix Available

This product has complete feed data (brand, category present) and still doesn't sell. The problem is demand, not discoverability. There's nothing to fix — the product simply doesn't sell through paid channels.

Exclude from paid campaigns. It may still sell through organic, email, or marketplace channels.

FIX FEED — Missing attributes

Fixable

This product has missing brand or category data. Google can't match it to relevant audiences. Fixing the feed may resolve the zombie classification — the product never had a fair chance to convert.

Update the product's brand and category in your Merchant Center feed. Wait 2–3 weeks after the fix before re-evaluating.

S16

Category Redeployment Plan

Page 4 — where should recovered budget go?

Each category's ROAS compared to account average, with a SCALE/HOLD/REDUCE verdict. Categories with ROAS 30%+ above average should receive the budget recovered from zombie exclusions. Categories 30%+ below average should be reduced.

SCALE CATEGORY

ROAS > 1.3x avg

This category outperforms the account average. Budget redirected here from zombie exclusions generates above-average returns. These categories should be your first destination for recovered spend.

Increase bid adjustments or budget allocation for this category in your listing group structure.
