A thorough ad account audit is one of the highest-value activities an agency can perform. It catches wasted spend, identifies missed opportunities, and gives you the evidence to have informed conversations with clients. The problem is that traditional audit checklists take hours per account, and most agencies do not have hours to spare.
After years of managing dozens of accounts simultaneously, I developed a 30-minute audit framework that focuses on the four areas where problems cost the most money: budget pacing, conversion tracking, wasted spend, and ad relevance. This is not a comprehensive, 100-point checklist. It is a focused process that catches the issues responsible for 80% of budget waste.
The 30-Minute Ad Account Audit Framework
The framework is built around four checkpoints, each allocated roughly 7 to 8 minutes. You move through them sequentially, flagging issues as you go without stopping to fix anything. The audit produces a list of findings. Fixes come later.
This separation between auditing and fixing is important. When you try to fix issues as you find them, a 30-minute audit becomes a 3-hour session. Audit first, prioritise second, fix third.
The four checkpoints are: budget pacing status, conversion tracking integrity, wasted spend identification, and ad relevance review. Each one targets a specific category of loss that compounds over time if left unchecked.
Google Ads Quick Checks (10 Minutes)
Google Ads accounts tend to accumulate waste in predictable places. These checks target the most common sources.
Search term waste. Pull the search terms report for the past 30 days. Sort by cost (descending) and scan the top 50 terms. Flag any term that has spent more than your target CPA without converting. These are the queries bleeding budget. In most accounts, 10 to 15 irrelevant search terms account for a disproportionate share of wasted spend.
Budget pacing status. Check each campaign's monthly spend against its target. Are campaigns pacing to land on budget? A campaign that is 40% through the month but has only spent 20% of its budget will underspend significantly. Conversely, a campaign that has burned 70% of budget by mid-month needs immediate attention.
Conversion action alignment. Open the conversions settings and verify that the primary conversion actions are correct. A common issue is accounts tracking page views or button clicks as primary conversions, which inflates Smart Bidding signals and wastes budget on low-quality actions. Every campaign should be optimising toward actions that represent genuine business value.
Bid strategy performance. For campaigns using automated bidding, check the bid strategy report. Look for strategies that are "limited by budget" or showing a learning period that has lasted more than two weeks. Both indicate that the campaign is not operating at its intended efficiency.
Meta Ads Quick Checks (10 Minutes)
Meta's algorithm behaves differently from Google's, and the audit checks reflect that. The primary concerns on Meta are learning phase disruption, audience overlap, and CBO allocation imbalances.
Learning phase status. Check the delivery column for each ad set. Any ad set stuck in "Learning Limited" is not optimising efficiently. This typically happens when the ad set does not generate enough conversions (roughly 50 per week) to exit learning. The fix is usually consolidating ad sets or broadening targeting, but for the audit, just flag it.
Audience overlap. Use Meta's audience overlap tool to check whether ad sets within the same campaign are competing against each other. Overlapping audiences drive up CPMs because you are bidding against yourself. Flag any overlap above 20% for review.
CBO allocation patterns. If the account uses Campaign Budget Optimisation, check how Meta is distributing budget across ad sets. CBO frequently funnels the majority of budget to one ad set while starving others. If an ad set with strong creative is getting less than 10% of budget, the algorithm may be making a suboptimal allocation decision. Flag imbalanced distributions for manual review.
Frequency and fatigue. Check the frequency metric for each ad set over the past 14 days. A frequency above 3 to 4 for prospecting campaigns suggests the audience is seeing the same ads too often. Performance typically declines as frequency rises, and CPAs increase alongside it.
LinkedIn Ads Quick Checks (5 Minutes)
LinkedIn's ad platform has its own quirks, and the audit checks account for them. LinkedIn campaigns tend to underspend rather than overspend, but the waste shows up in different ways.
Audience size. Check the estimated audience size for each campaign. LinkedIn campaigns targeting audiences below 50,000 members often struggle to deliver consistently. The platform needs a large enough pool to optimise within. Flag any campaign with an audience below this threshold.
Daily budget vs. actual spend. LinkedIn can overshoot daily budgets by up to 50% on any given day. Check whether actual daily spend is consistently exceeding your set budget. If so, reduce the daily budget to account for this overshoot. Also check for chronic underspend, where campaigns are only using 60 to 70% of their daily allocation.
Lead form performance. If the account uses LinkedIn Lead Gen Forms, check the form completion rate. A low completion rate (below 10%) usually indicates that the form has too many fields or the offer is not compelling enough. Compare lead form CPAs against website conversion CPAs to determine which path is more efficient.
Turning Audit Findings into Action
The audit produces a list of flagged issues. The next step is prioritisation. Rank each finding by estimated financial impact: how much budget is being wasted or underutilised because of this issue?
High-impact items get fixed first. A search term wasting $500 per month takes priority over a minor audience overlap. This prioritisation ensures that the audit drives measurable improvement, not just a long list of to-dos that never gets completed.
Document everything. A change log that records what you found, what you changed, and why you changed it serves two purposes. It creates accountability within your team, and it demonstrates value to clients who want to see that their agency is actively protecting their budget.
How Automated Audit Tools Reduce This to 5 Minutes
The 30-minute framework works well for manual audits, but it still requires logging into each platform, pulling reports, and reviewing data by hand. Automated audit tools compress this process by connecting to your ad accounts via API and running these checks continuously.
Pace monitors budget pacing, spend anomalies, and performance deviations across Google, Meta, LinkedIn, and Microsoft Ads. Instead of running a monthly audit, the system flags issues as they emerge. A pacing deviation that would take days to notice in a manual review gets flagged within hours.
The shift from periodic auditing to continuous monitoring changes the value equation. You are no longer catching problems after they have cost money. You are catching them before they compound. For agencies managing ten or more accounts, this difference adds up to thousands in preserved budget each month.
Run your first 30-minute audit this week using the framework above. Once you see the issues it surfaces, you will understand why continuous monitoring is worth the investment.
