Google Can’t Audit
Its Own Waste
Google’s incentive is more ad spend, not less waste. These audits are the independent accountability layer — connect your account, get a PDF diagnostic with exact dollar figures and action steps in under 3 minutes.
Run 13 independent Google Ads audit tools covering wasted spend detection, Performance Max transparency, Search Query Bleed from broad match expansion, Shopping feed zombie products, conversion signal quality, Ads-vs-GA4 tracking mismatch, mobile app placement leakage, brand cannibalization, margin erosion after COGS, spend concentration risk, and AI Max signal health — all free, read-only access, no credit card required.

Google Ads Waste Audit
Your 30-day waste forensics. We calculate exact leakage rate, map every zero-conversion search term, run a device friction analysis, and build a negative keyword action list — with a monthly savings forecast.
- Exact leakage rate & recovery $
- Negative keyword action list
- Hourly waste heatmap
Search Query Bleed Audit
Broad Match and AI expansion are burning budgets silently. This audit calculates your exact bleed rate, maps which keywords expand into the most junk queries, and compares Human-Controlled CPA vs AI-Expanded CPA side by side.
- Bleed rate (% of search spend wasted)
- Keyword expansion rate per term
- Human vs AI CPA comparison
Small Budget Survival Guide
Under $5k/month, every wasted dollar hurts 10x harder. We calculate your Survival Score, show your true Effective Budget after waste, and give you a 10-minute Kill Switch list — campaigns and queries to pause immediately.
- Survival Score (0–100)
- True Effective Budget after waste
- Kill Switch: pause list + negative keywords
Spend Concentration Audit
If one campaign absorbs 60% of budget, your account is one algorithm hiccup from collapse. We calculate the Gini Index, identify starved-but-efficient campaigns, and build a SCALE / CUT / HOLD rebalance matrix for every campaign.
- Budget Gini Index (0–1 scale)
- Starved winners (efficient + budget-capped)
- Rebalance matrix with transfer simulation
Signal & Tracking
Verify the data the algorithm uses to make bid decisions
Conversion Quality Audit
Google counts view-through, cross-device, and modeled conversions alongside real clicks — then bids on all of them equally. We break the split per campaign, scatter-plot Ads vs GA4 drift, and flag every conversion action with deduplication risk.
- Click vs Modeled conversion split
- Attribution drift scatter (Ads vs GA4)
- Deduplication risk per action
Tracking Mismatch Audit
If Google Ads says 500 conversions and GA4 says 300, Smart Bidding is optimizing on 200 phantom signals. We compare both platforms per campaign, test 7-day vs 30-day drift, and give every campaign a Bidding Trust verdict.
- Absolute Ads↔GA4 gap per campaign
- Signal density (conv/click ratio)
- Bidding Trust: safe / caution / do not trust
AI Max Signal Audit
The algorithm trains on your conversion data — but how much of that data is real? We score Signal Health per campaign, measure Machine vs Human CPA (with brand excluded), surface phantom conversion spend, and build an immediate Override Action checklist.
- Signal Health Score (0–100)
- Machine vs Human Trust Score (CPA)
- Override action checklist (sorted by $)
Shopping & Products
SKU-level waste, margin analysis, and feed diagnostics
Zombie Products Audit
Products with 20+ clicks and zero sales are training the algorithm on failure. We use a currency-adaptive threshold to catch every zombie, calculate daily burn rate per SKU, cross-reference with GA4 cart/purchase data, and classify each as EXCLUDE / FIX FEED / MONITOR.
- Zombie count + daily burn rate
- GA4 cross-reference (confirmed dead?)
- Action split: exclude / fix feed / monitor
Shopping Waste Audit
A decent blended ROAS hides dead weight. We map product performance tiers (converting vs zombie vs untested), compare your CPC and CTR against Google's Shopping benchmarks, and build a priority-ranked exclusion list with projected recovery value.
- Product performance tier breakdown
- Your CPC/CTR vs Google benchmarks
- Priority exclusion list + recovery projection
Margin Erosion Audit
A 4x ROAS means nothing if your margin is 10%. We pull COGS from your Shopping feed, calculate break-even ROAS per category, and build a revenue-to-profit waterfall that shows exactly where margin disappears — with a Kill List and Scale List.
- True Profit After Ads (revenue − COGS − ad spend)
- Break-even ROAS per product category
- Kill list (pause) + Scale list (push budget)
Placement & Brand
Control where ads appear and how much goes to brand defense
Placement Leakage Audit
PMax hides where your ads actually appear. We aggregate placement data from PMax + Standard + Video, calculate the Mobile App Black Hole percentage, and build an exclusion list — with estimated cost per junk placement using your account CPM.
- Mobile App impression % (the junk ratio)
- Top offender apps, channels, and sites
- Exclusion list + estimated cost per placement
Brand Leakage Audit
Your blended ROAS is a lie if 50% of spend captures people already searching your name. We split Brand vs Non-Brand CPA and ROAS by campaign and channel, surface cannibalization overlap (brand terms in non-brand campaigns), and calculate the incremental cost of paying for demand you already own.
- Brand Spend % + dependency verdict
- Cannibalization overlap (double-paying)
- Incrementality cost (70%-weighted estimate)
Performance Max Audit
The algorithm decides everything in PMax — channel mix, placements, audiences, creatives. We calculate an Algorithm Control Index (0–100), classify waste by category (exploration vs creative), surface junk placements, and run an Exploration Efficiency Ratio to tell you if learning spend is finding value or burning money.
- Algorithm Control Index (ACI)
- Waste waterfall (exploration vs creative)
- Exploration Efficiency Ratio (EER)

Frequently asked questions
Are these Google Ads audit tools really free?+
Yes. All 13 audit tools are free analysis — no credit card, no trial period. They use read-only Google OAuth access so no passwords are stored and no changes are made to your account. You receive a one-time PDF diagnostic report with exact dollar figures, action items, and recovery projections.
Will ClickCatalyst make changes to my Google Ads account?+
Never. All free audit tools use read-only API access. ClickCatalyst reads campaign performance data to generate diagnostic reports — it never modifies campaigns, budgets, bids, keywords, or any account settings.
How long does a Google Ads audit take?+
Setup takes under 60 seconds — connect your Google Ads account and optionally GA4 via OAuth. Diagnostic queries run and results are generated in under 3 minutes. You receive a multi-page PDF with visualizations, tables, and specific action steps.
What is the difference between the Waste Audit and the Search Query Bleed Audit?+
The Waste Audit covers all waste categories — search terms, device friction, match type waste, bidding misalignment, and hourly gaps. The Search Query Bleed Audit goes deeper on search term waste: it measures keyword expansion rate, compares Human-Controlled vs AI-Expanded CPA, and includes query length analysis showing that longer queries convert better.
What are zombie products in Google Ads?+
Zombie products are Shopping items that received 20+ clicks with zero units sold, above a currency-adaptive spend threshold. The Zombie Products Audit identifies every zombie SKU, calculates daily burn rate per product, cross-references with GA4 cart and purchase data, and classifies each as EXCLUDE, FIX FEED, or MONITOR.
What is the difference between the free audits and ClickHub?+
The free audits give you a one-time diagnostic snapshot — a PDF report with findings and action steps. ClickHub is the full SaaS platform that runs all 13 audits continuously: live dashboards, automated waste detection alerts, campaign maturity tracking, one-click fixes, and multi-account management.
