PPC Audit Checklist: 9 Steps to Find Wasted Ad Spend

A PPC audit is a structured review of your Google Ads account that tells you where money is leaking and what to fix first. The order matters: define your business targets, confirm conversion tracking is trustworthy, then work through structure, settings, search terms, ads, bids and growth opportunities. This checklist walks through each step and ends with a way to turn findings into a ranked action plan.

TL;DR

  • Start with business goals and profit targets, not platform benchmarks. An audit without that context is just a technical checklist.
  • Verify conversion tracking before anything else. If conversion data is wrong, every other conclusion in the account can be wrong too.
  • Review structure, settings, search terms, ads and landing pages, then bids and budgets.
  • Rank each finding by severity and impact, and give every action an owner, a date and a completion condition.
  • Repeat the audit on a regular schedule, and after any big change to the account.

What a PPC audit should cover

Whether you call it a Google Ads audit checklist or a PPC account audit, the scope is the same. You are checking six areas:

  1. Business goals and conversion definitions
  2. Tracking and reporting accuracy
  3. Account structure and campaign settings
  4. Keywords, search terms and negative keywords
  5. Ads, assets and landing pages
  6. Budgets, bids and growth opportunities

One audit guide from AdsCockpit makes a point we agree with: targets should come from profitability and business goals, not abstract benchmarks. A cost per click that looks high in a chart can be perfectly healthy if the lead closes at a good margin. A cheap click that never converts is the expensive one.

Step 1: Prepare before you open the account

Good audits are decided before the first report is pulled. Gather these inputs:

  • Business objectives. Leads, sales, booked appointments, signed cases or store visits. Name the one that matters most.
  • Profitability targets. Your maximum cost per acquisition or minimum return on ad spend, worked out from margin and customer value.
  • History. Past changes, seasonal peaks, launches, budget cuts and agency handoffs.
  • Conversion definitions. What counts as a conversion, and which ones are real business events.
  • Access. Google Ads, Google Analytics, Google Tag Manager and, ideally, your CRM or sales data.

Then export the evidence. The Ninja Scripts Academy tutorial on auditing an inherited account suggests pulling campaign, keyword, search-term, ad, placement, conversion and change-history exports, using a 90-day working range plus a prior-year comparison to account for seasonality.

If you are unsure what your target cost per thousand impressions or per lead should look like, a SaaS CPM calculator can help you set a business-based benchmark before you judge any campaign.

Step 2: Verify conversion tracking

This is the step most audits should start with and many skip. Search Engine Land’s tips for Google Ads audits put it plainly: trust your conversion data before you draw conclusions from the rest of the account, because untrusted conversion data can make everything else wrong.

For each conversion action, check:

  • Does it measure the intended business event, such as a submitted form or a completed call, rather than a page view?
  • Is it set as primary or secondary correctly?
  • What is the counting method (every conversion or one per click)?
  • What value, attribution model and conversion window apply?
  • Is consent handled properly, and do tag diagnostics show healthy tags?

Then test the real path. Submit a form, place a call, complete a checkout. Where possible, reconcile transaction or lead IDs between your source system, the import log, Google’s acceptance and the conversion-action report, as described in this conversion tracking audit checklist.

Do not mistake discrepancies for broken tags

Google Ads and Analytics rarely match exactly. Google’s own data discrepancy guide explains that Google Ads reports conversions on the impression date while other tools may use the conversion date, and recommends allowing 24 to 48 hours for synchronization with Analytics. Conversion delay and modeled data also cause totals to diverge. Align windows and definitions before you declare tracking broken.

Phone leads are a common blind spot. If calls drive your revenue, see our guide to call tracking marketing. For reporting setup in Analytics, our GA4 reporting guide includes templates you can copy.

Step 3: Check campaign structure and settings

Start with the account’s own diagnostics. Google’s Campaign Diagnostics checks campaign health across more than 90 signals, including account issues, ads, audiences, bidding and budget, business data, goals, products and signals. Treat it as a first pass, then look manually.

Structure. Campaigns should be organized consistently and logically, by theme, product line, match type, geography or funnel stage. According to AdsCockpit, catch-all campaigns, or ad groups with more than 15 to 20 keywords or overlapping themes, may signal poor segmentation.

Settings. Audit these one by one:

  • Search Partners and Display Network opt-ins
  • Location targeting and language
  • Bid strategy and ad rotation
  • Budget allocation and shared budgets
  • Stale campaigns and leftover experiments

Wrong-location targeting is a classic silent leak. A local clinic or law firm paying for clicks from outside its service area is burning budget with no chance of a return.

Step 4: Audit keywords and search terms

The search-terms report shows what people typed before they saw your ad. Search Engine Land’s piece on auditing Google Ads with limited data notes that the terms you can still see remain valuable. Use them three ways:

  • Add high-performing queries as keywords.
  • Exclude irrelevant queries and those with a high CPA.
  • Move queries that do not match their ad group’s theme to a better home.

Keywords and negative keywords should reflect your industry, audience, offerings and business goals. Unbounce’s Google Ads audit guide adds that aligning keywords, ads and landing pages supports relevance and helps keep CPC in check.

A simple working table for this step:

Finding What it looks like Action
Winning query not yet a keyword Converts at or below target CPA Add as exact or phrase match
Irrelevant query Spend with no link to your offer Add as negative keyword
Theme mismatch Query triggers the wrong ad group Move or restructure
Overlap Two ad groups compete for the same terms Consolidate or add negatives

Step 5: Review ads, assets and landing pages

For each ad group, ask whether the ad promises what the landing page delivers. Check that headlines reflect the keyword theme, that assets such as sitelinks and call extensions are present and accurate, and that several ad variations are running so you can learn something. Then open the landing page on a phone. Slow load, a buried form or a message mismatch will waste the click you paid for.

If landing pages are the weak link, that is a website problem, not an ads problem, and fixing it often lifts every campaign at once.

Step 6: Audit budgets and bids to find wasted spend

Google’s guidance on evaluating and optimizing bids suggests using reports to identify the keywords, locations, devices and peak sales periods that perform best. Compare costs against revenue. Consider reducing bids on high-CPC keywords with low conversion rates, and raising bids on low-CPC keywords that convert well.

Work through these questions:

  • Which campaigns hit their budget cap early while others leave budget unused?
  • Are bid strategies matched to the volume of conversion data available?
  • Do device, location or time-of-day segments show a clear gap in cost per conversion?
  • Is spend concentrated where profit is, or where clicks are cheap?

Step 7: Look at quality signals, remarketing and growth

Check Quality Score components (expected click-through rate, ad relevance, landing page experience) at the keyword level to find where relevance is weakest. Review Display and remarketing placements for irrelevant sites, and confirm that audience lists are populated and recent. Then list growth opportunities: untapped keyword themes, new geographies you serve, new ad formats, and competitor-adjacent queries you do not yet cover.

Industry context matters here. A dental practice, a law firm and a retailer all audit differently, because lead value and sales cycle differ. If that is your world, our playbooks for Google Ads for dentists, Google Ads for doctors and law firm PPC go deeper.

Step 8: Rank findings and build the action plan

An audit that ends in a 60-item list gets ignored. Rank every finding. Aubado’s audit guide suggests this scale:

Severity Examples Timing
Critical Broken conversion tracking, wrong-location targeting, significant wasted budget Fix immediately
High Material performance issues Within a week
Medium Efficiency issues Within the month
Low Cosmetic issues When time permits

Record each finding with its severity, estimated impact and recommended fix. For the actions you select, add an owner, a date, a baseline number and an observable completion condition, such as “cost per lead below target for 14 days.”

Step 9: Schedule the next audit

Book the next review before you close this one. Rerun the tracking check after any website change, and a fuller review after major budget shifts, seasonal peaks or a change of agency. Keep the evidence pack from this audit so the next one starts with a clean baseline.

Our perspective

Most accounts we are asked to look at do not have a clicks problem. They have a measurement problem. Someone set up conversions years ago, the business changed, and the account kept optimizing toward the wrong signal.

That is why we start every review with business goals and tracking, then move to structure, search terms and creative. After 18 years working with startups and household brands across healthcare, legal, retail and consulting, we have found that the audit is only valuable when it ends in decisions: what to stop, what to scale, and who owns each change.

Our in-house, multidisciplinary team is built to work as an extension of yours, bridging strategy and execution so findings do not sit in a spreadsheet.

FAQ

How often should I run a PPC audit?

A full audit once or twice a year suits most stable accounts. Run a lighter check, focused on tracking, search terms and budgets, every month or quarter. Repeat the full review after major site changes, budget changes or a handoff to a new team.

What should I check first in a Google Ads audit?

Check conversion tracking first. Confirm each conversion measures a real business event and that a test submission or call shows up correctly. If conversion data is unreliable, the rest of your analysis rests on bad numbers.

What data do I need before auditing a PPC account?

You need your business goals, profit targets, and access to Google Ads, Analytics and Tag Manager. Your CRM or sales data helps you judge lead quality. Export campaign, keyword, search-term, ad, conversion and change-history reports for roughly the last 90 days, plus a prior-year comparison.

Why do Google Ads and Analytics show different conversion numbers?

The two tools count differently. Google Ads reports conversions on the ad-impression date, while other tools often use the conversion date, and syncing can take 24 to 48 hours. Align definitions and date ranges before treating a gap as a tracking error.
