Free Ads Audit

Turn campaign totals into a focused audit of creative response, conversion efficiency, evidence volume, and contribution after ad spend.

Runs in your browser

Your inputs

Enter one campaign or account period

Use totals from the same date range, currency, and attribution view. The targets below are yours; the audit does not impose a universal industry benchmark.

Profitability check

Contribution after ads = revenue × gross margin − ad spend

A positive platform ROAS can still be below break-even when product margin is thin.

Live result

A directional campaign diagnosis

The score organizes the review. It is not a platform quality score and should not trigger an automatic budget change.

Revenue does not cover ad spend at this margin

ROAS is 1.80×, below the 1.82× break-even ROAS. Check product margin before scaling.

Check the creative and audience match

CTR is 1.30%, below your 1.50% target. Review the hook, offer, placement, and audience before changing the landing page.

Inspect the landing page and offer

Click-to-conversion rate is 2.00%, below your 3.00% target. Check message match, page speed, price, and checkout friction.

There is enough conversion volume for a directional review

52 conversions give this aggregate diagnosis more stability, although segment-level decisions still need their own evidence.

Quick answer

This free ads audit turns one campaign or account period into four checks: unit economics, creative response, post-click conversion, and evidence volume. It uses your own CTR and conversion targets and calculates break-even ROAS from the gross margin entered.

The output is a troubleshooting order, not a command to pause or scale. Low CTR points first toward the hook, offer, placement, or audience. Adequate CTR with low conversion shifts attention toward message match, price, page experience, or checkout.


The ads audit calculation

Calculation

Contribution after ads = attributed revenue × gross margin − ad spend

  • CTR equals clicks divided by impressions.
  • Click-to-conversion rate equals conversions divided by clicks.
  • CPA equals spend divided by conversions; ROAS equals attributed revenue divided by spend.
  • The score weights profitability, response against your target, conversion against your target, evidence volume, and input completeness.

How to use the free tool

  1. 1

    Align the data scope

    Use the same date range, account or campaign scope, currency, and attribution view for every total.

  2. 2

    Use your targets

    Enter targets that reflect the placement, objective, audience, and funnel instead of borrowing an unrelated industry average.

  3. 3

    Read the funnel in order

    Start with delivery and clicks, continue to conversion, then compare revenue contribution with ad spend.

  4. 4

    Segment before changing

    Inspect campaigns, creatives, audiences, products, devices, and landing pages to find what creates the aggregate result.


How to find the first bottleneck

CTR below target

Review creative, audience, offer, placement, and fatigue. Do not rebuild the checkout before confirming people want to click.

Conversion below target

Inspect message match, page speed, merchandising, price, stock, shipping, and checkout friction after the click.

ROAS below break-even

Revenue return does not cover ad spend at the margin entered. Check contribution and attribution before increasing budget.

Low evidence volume

Ratios can move sharply with a few additional conversions. Extend the window or use a higher-volume level for the first decision.


What the result does not prove

  • Aggregate totals cannot identify the campaign, creative, product, or audience that caused the result.
  • Attributed revenue can differ from store revenue because platforms use different attribution models and conversion windows.
  • The directional evidence threshold is not a statistical significance test.

When you need account-specific evidence, copy the task from the result panel. Install BizSidekick without making a payment, connect only the accounts required for the task, and ask it to verify the browser result before preparing supported changes for review.

Frequently asked questions

What does the free ads audit check?

It calculates CTR, CPC, click-to-conversion rate, CPA, ROAS, break-even ROAS, contribution after ad spend, and evidence volume, then organizes those signals into a directional diagnosis.

Does the audit use industry benchmarks?

No. You enter the CTR and conversion-rate targets that are relevant to your account. The profitability check uses the gross margin you enter instead of a universal ROAS target.

Why can ROAS be positive while contribution is negative?

ROAS measures revenue, not gross profit. When contribution margin is lower than the share of revenue consumed by ads, the campaign can show revenue return and still lose money.

Can the audit tell me which campaign to pause?

The browser tool only reviews the aggregate totals you enter. Use connected account data to inspect campaign, audience, creative, product, and landing-page segments before making a change.

How many conversions are enough for an ads audit?

There is no universal threshold. The tool flags fewer than 30 conversions as lower evidence for an aggregate directional review, but segment-level decisions may need a longer window or a formal statistical method.
