What Is a PPC Audit and Do I Need One?

Whether you need one depends on where you are: new to PPC, suspicious that something’s off, or simply overdue for a check-in on an account you’ve been running for a while.

What a PPC Audit Actually Covers

A thorough audit is not a surface-level report showing you your click-through rate. It goes deeper, into account structure, tracking integrity, budget efficiency, and strategic alignment. Here’s what it should include:

Conversion Tracking and Measurement

This comes first because everything else depends on it. If your conversion tracking is broken, misconfigured, or measuring the wrong events, every optimization decision in your account is built on faulty data.

A proper audit checks: – Are all intended conversion actions firing correctly? – Is there any double-counting (the same conversion firing multiple times from one action)? – Are conversions mapped to the right value? – Is Google Analytics (GA4) linked to the account and consistent with Google Ads conversion data? – Are any conversion events measuring low-value actions (page views, scroll depth) that shouldn’t be counted?

Conversion tracking issues are the most common finding in audits of accounts that “aren’t working.” Often the campaigns are fine. The measurement is broken.

Account and Campaign Structure

Poor structure is a hidden tax on performance. It inflates costs, limits optimization control, and makes the account harder to manage over time.

Structure review includes: – Are campaigns segmented by intent type, product line, or funnel stage? – Are ad groups too broad (many unrelated keywords per group) or too narrow? – Is the account using the right campaign types for each goal? – Are branded and non-branded keywords properly separated? – Is there logical budget allocation across campaigns relative to their value?

Keyword Quality and Negative Lists

Keywords are the foundation of Search campaigns. Bad keyword selection (too broad, too irrelevant, or too generic) is one of the fastest ways to burn budget.

Keyword audit covers: – Review of search terms actually triggering ads (not just the keywords in the account) – Identification of irrelevant, low-intent, or competitor-polluted queries – Assessment of negative keyword coverage: are obvious negatives being excluded? – Match type review: is excessive broad match driving low-quality traffic? – Identification of keyword cannibalization between campaigns

Ad Copy and Creative Quality

Ads are the first thing a potential customer sees. Weak ad copy means high impression volume but low click-through rates, which hurts Quality Scores and raises CPCs.

Creative review covers: – Are responsive search ads using all available asset slots? – Is ad copy specific and benefit-focused, or vague and generic? – Are headlines and descriptions testing different messages? – Are ad customizers and dynamic keyword insertion used where appropriate? – Do ads align clearly with landing page content (message match)?

Landing Page and Conversion Experience

High click-through rates with low conversion rates usually point to a landing page problem. The audit should assess: – Load speed (slow pages kill conversions on mobile) – Message match between the ad and landing page – Clarity of the call to action – Mobile usability – Form friction (number of fields, layout)

Bidding Strategy and Budget Efficiency

• Is the bidding strategy appropriate for the account’s conversion volume?
• Is budget being exhausted early in the day (budget-limited campaigns)?
• Are there campaigns spending heavily on low-converting times, devices, or locations?
• Are audience bid adjustments being used?

Quality Score

Quality Score is Google’s rating of ad relevance, expected CTR, and landing page experience. Higher Quality Scores mean lower CPCs and better ad placement. The audit should identify which keywords have low Quality Scores and diagnose why.

Signs You Need a PPC Audit Now

You’ve been running campaigns for 3+ months and aren’t seeing profitable results. This is the most common trigger. The default explanation is “Google Ads doesn’t work for my business,” but the actual cause is often a fixable structural or tracking issue.

Your CPC has been climbing steadily. Rising costs without rising conversion rates usually mean deteriorating Quality Scores, keyword dilution, or competitive shifts, all diagnosable issues.

You just took over an account from another agency. Before spending money to manage someone else’s structure, you need to understand what you inherited. Audits catch legacy problems before they become your problems.

You’ve never had one. If your account has been running for 12+ months without an external review, there’s almost certainly waste and missed optimization opportunity. Accounts drift without active oversight.

You’re about to scale. Before significantly increasing budget, an audit ensures you’re not scaling a broken machine. Scaling an unaudited account often means spending more on the same inefficiencies.

Your reports look fine but leads feel low-quality. If you’re generating leads but they’re not converting to customers, the issue may be keyword intent (too broad), audience mismatch, or landing page misalignment. An audit surfaces where the quality breakdown is.

What You Get From an Audit

A useful audit delivers: – A clear picture of what’s working and should be protected – Specific, prioritized list of issues to fix – Estimate of wasted spend that could be recovered – Structural recommendations for the account – A roadmap for the next 30–90 days

What it should not be is a sales pitch disguised as an audit. If every finding conveniently requires retaining the agency doing the audit, be skeptical.

How Often Should You Run One?

For accounts spending under $5,000/month with consistent performance: annually is reasonable.

For accounts spending $5,000–$20,000/month: every 6 months, or any time there’s a significant performance shift.

For accounts spending over $20,000/month: quarterly, or in conjunction with major strategy changes.

For any new engagement, whether you’re a new advertiser or a new agency taking over an account, an audit at the start is non-negotiable.

Getting an Audit Done

You can run one yourself if you’re technically capable. Google’s interface provides most of the data you need, and there are audit checklists available. For most business owners, though, a self-audit misses structural issues that aren’t obvious without pattern recognition from managing many accounts.

A third-party audit from someone not currently managing your account adds an independence layer that internal reviews can’t replicate. The auditor has no incentive to protect what’s already there.

We offer free PPC audits for accounts that meet the minimum spend threshold. The deliverable is a documented findings report, not a 30-minute call where someone talks in circles. If you want to know what’s actually happening in your account, request an audit here.
