Google Ads makes it easy to spend money.

It does not make it easy to know whether that money is working.

Campaigns get launched with default settings. Conversion actions get added and never cleaned up. Automated recommendations get applied. Agencies change. Team members leave.

A year later, the account is still running, the invoices are still arriving, and nobody can say with confidence which clicks are turning into customers.

That is exactly what an audit is for.

Before you raise your budget, change agencies, or give up on paid search, find out where the account is actually leaking.

Why Run a Google Ads Audit?

Google Ads has become far more automated. Smart Bidding, broad match, Performance Max, and AI-generated assets can all perform well, but they all depend on the signals you feed them.

If those signals are wrong, automation simply scales the mistake faster.

An audit is worth running when:

• cost per lead is rising and nobody can explain why
• the account reports plenty of conversions, but sales says lead quality is poor
• you are inheriting an account from a previous agency or employee
• you are about to increase budget significantly
• you have not reviewed settings, search terms, or conversion actions in months
• you are comparing paid search against other channels and need trustworthy numbers

That last point matters. If you are deciding how to split budget between channels, our breakdown of SEO vs PPC ROI only works when both channels are measured accurately.

Google Ads Audit vs. Optimization Score vs. Routine Management

Many business owners assume the optimization score in their account already tells them how healthy it is. It does not, at least not in the way an audit does.

Google itself describes optimization score as “an estimate of how well your Google Ads account is set to perform” and notes that it is not used by Quality Score (Google Ads Help). A high optimization score can coexist with poor lead quality. Treat recommendations as suggestions to evaluate, not instructions to accept.

Step 1: Audit Conversion Tracking First

Every audit should start here. If conversion data is wrong, every other conclusion in the audit is built on sand.

1. List Every Conversion Action

Open the conversions summary and write down each action, its source, its status, and whether it is set as a primary or secondary action. Old, duplicate, or test conversion actions are common in inherited accounts.

2. Confirm What Smart Bidding Is Optimizing Toward

Primary conversion actions are what bidding strategies use. If page views, button clicks, or time-on-site events are counted as primary conversions alongside real form fills and calls, automated bidding may chase cheap, low-value actions.

3. Test Forms and Calls Yourself

Submit a test lead and place a test call. Check that each one is recorded once, not zero times and not twice. Duplicate firing is one of the most common reasons an account looks healthier than it is.

4. Check Counting Settings

For lead generation, counting one conversion per click is usually more realistic than counting every conversion, because one person submitting a form twice is still one lead.

5. Connect Online Leads to Offline Outcomes

For service businesses and B2B companies, the real outcome happens after the form: a qualified call, a booked estimate, a signed contract. Google’s enhanced conversions for leads lets advertisers measure those offline conversions using first-party data already in their CRM, with the data hashed before it is sent to Google (Google Ads Help). Feeding qualified-lead or closed-deal data back into the account is one of the highest-impact changes most lead generation advertisers can make.

Step 2: Review Campaign Settings and Structure

Settings problems are quiet. They rarely trigger alerts, but they can send budget to places you never intended.

1. Location Targeting Options

Check whether campaigns target people located in your service area or people who have shown interest in it. For a local service business, the broader option can produce clicks from people who will never become customers.

2. Network Settings

Review whether Search campaigns are opted into the Search Partners network or Display expansion. Neither is automatically bad, but each should be a deliberate decision backed by segmented performance data.

3. Auto-Applied Recommendations

See which recommendation types are set to apply automatically and review the change history. Automatically added keywords, broadened match types, or new assets can change account behavior without anyone reviewing them first.

4. Ad Schedule and Devices

If your team cannot answer calls at night or on weekends, call-focused ads running at those times may be generating missed opportunities rather than leads.

5. Campaign Structure

Look for campaigns that mix unrelated services, branded and non-branded terms, or very different profit margins. When high-value and low-value services share one budget, the account cannot prioritize the work you actually want.

Step 3: Audit Keywords and the Search Terms Report

Keywords tell Google what you want to show for. The search terms report tells you what you actually paid for. The gap between the two is where most wasted spend hides.

1. Sort Search Terms by Cost, Not Clicks

Start with the most expensive search terms that produced no qualified conversions. Those are your biggest, fastest savings.

2. Classify Intent

Separate terms into buying intent, research intent, job seekers, DIY searchers, competitors, and irrelevant traffic. Paid search budgets should lean heavily toward commercial intent keywords and bottom-of-funnel keywords, where the searcher is close to a decision.

3. Build and Organize Negative Keywords

Add negatives for recurring irrelevant themes such as “jobs,” “free,” “DIY,” or services you do not offer. Shared negative keyword lists keep this consistent across campaigns.

4. Review Match Types With Bidding in Mind

Broad match can work when it is paired with accurate conversion data and Smart Bidding. Without reliable conversion signals, it often expands into loosely related searches. The match type decision and the tracking decision are connected.

5. Include Performance Max Search Terms

Performance Max used to be a black box for search queries. Google has been rolling out Performance Max search terms in the standard search terms report, along with the ability to add negative keywords from it, as reported by Search Engine Land. If your account has access, include those queries in the audit.

Step 4: Evaluate Ads, Assets, and Quality Score

1. Read Quality Score as a Diagnostic

Google reports Quality Score on a 1–10 scale at the keyword level, built from expected clickthrough rate, ad relevance, and landing page experience, each rated against other advertisers whose ads showed for the same search. Google also states that Quality Score is not an input in the ad auction (Google Ads Help). Use the component ratings to find where ads or pages are misaligned, not as a goal in itself.

2. Check Message Match

The ad, the keyword, and the landing page should all describe the same offer. If someone searches for emergency service and lands on a generic homepage, relevance and conversion rate usually both suffer.

3. Review Asset Coverage

Check that sitelinks, callouts, structured snippets, call assets, and location assets are present where relevant, accurate, and pointing to working pages.

4. Look for Differentiation

If your headlines could be swapped with a competitor’s without anyone noticing, they are not doing enough. Specific proof points, service areas, guarantees you actually offer, and clear next steps tend to outperform generic claims.

Step 5: Assess Bidding Strategy and Budget Allocation

Bidding strategy should match the quality and volume of your conversion data.

A common pattern in lead generation accounts: the best-performing service campaign is capped by budget while a broad, low-quality campaign spends freely. Reallocating budget can improve results without spending a dollar more.

Step 6: Audit Landing Pages and Lead Handling

An ad account can be perfectly managed and still fail if the click lands on a weak page or the lead is never followed up.

• Does the page load quickly on mobile?
• Is the offer in the headline the same one promised in the ad?
• Is the phone number clickable and the form short?
• Is there real proof: reviews, credentials, service areas, project examples?
• Is the page focused on one action, or full of navigation that leaks attention?
• How quickly does someone actually respond to new leads?

The same principles apply to organic traffic. If your landing pages convert poorly in general, our guide on why traffic isn’t converting covers the page-level fixes in more depth.

How to Prioritize Fixes: The PPC Leak Score

A thorough audit often produces dozens of findings. Fixing them in random order wastes time. We use a simple prioritization framework called the PPC Leak Score.

Score each finding from 1 to 5 on four factors, for a maximum of 75.

• Spend at Risk: How much budget is affected by this issue?
• Lead Quality Impact: How much does it affect whether leads become customers?
• Measurement Impact: Does it distort the data that bidding and reporting rely on?
• Ease of Fix: How quickly and safely can it be corrected? (5 = minutes, 1 = a major rebuild)

Worked example (hypothetical numbers): a duplicate form conversion that fires twice per lead scores Spend at Risk 4, Lead Quality Impact 3, Measurement Impact 5, and Ease of Fix 5. That gives (4 + 3 + 5) × 5 = 60. A full campaign restructure might score (4 + 4 + 2) × 1 = 10. Both matter, but the tracking fix comes first because it is high-impact, fast, and makes every later decision more accurate.

The score is a sequencing tool, not a verdict. Lower-scoring items like landing page rebuilds can still be essential. They just belong later in the plan, after the quick, data-protecting fixes are done.

Google Ads Audit Mistakes to Avoid

Auditing Performance Before Auditing Tracking

Judging campaigns on cost per conversion before confirming that conversions are real leads to confident but wrong decisions.

Changing Everything at Once

Rebuilding campaigns, switching bid strategies, and launching new landing pages in the same week makes it impossible to know what helped or hurt. Sequence the changes.

Accepting Every Recommendation

Recommendations can be useful, but they are not written with your margins or sales process in mind. Evaluate each one.

Ignoring Sales Feedback

The people answering the phones often know which campaigns produce real customers. An audit that never talks to sales misses half the picture.

Treating the Audit as a One-Time Event

Accounts drift. Settings change, recommendations get applied, and new search behavior appears. A light monthly check and a deeper quarterly review keep small leaks from becoming big ones.

Should You Audit In-House or Hire a PPC Agency?

An in-house audit works well when someone on your team understands Google Ads deeply and has the time to be objective about decisions they may have made themselves.

An outside audit makes sense when you are inheriting an account, when performance has stalled and nobody can explain why, or when you want an unbiased second opinion before increasing spend. If you are evaluating partners, our guide on how to choose a PPC management agency covers the questions to ask.

Google Ads Audit FAQs

What is included in a Google Ads audit?

A complete audit reviews conversion tracking, campaign structure and settings, keywords and search terms, negative keywords, ads and assets, bidding strategies, budget allocation, landing pages, and how leads are handled after they arrive.

How often should I audit my Google Ads account?

Most businesses benefit from a light monthly check of search terms, conversions, and change history, plus a deeper audit every quarter or before any significant budget increase.

What is the first thing to check in a Google Ads audit?

Conversion tracking. Confirm that each primary conversion action represents a real business outcome and fires exactly once per lead before evaluating campaign performance.

Is a high optimization score a sign of a healthy account?

Not necessarily. Google describes optimization score as an estimate based on its recommendations. It does not account for your margins, lead quality, or sales outcomes, so it should not replace a real audit.

Does Quality Score affect what I pay?

Google states that Quality Score is a diagnostic tool and not an input in the ad auction. Its components reflect the same ad quality factors that matter in the auction, which is why improving relevance and landing page experience is still worthwhile.

How do I find wasted spend in Google Ads?

Sort the search terms report by cost and look for terms with spend but no qualified conversions. Then review location, network, and schedule settings for budget going to audiences that cannot become customers.

Can I see search terms for Performance Max campaigns?

Google has been rolling out Performance Max search terms in the standard search terms report, along with the ability to add negative keywords from that report. Availability can vary by account during rollouts.

How do I know if my Google Ads leads are good quality?

Compare ad-sourced leads against CRM outcomes such as qualified calls, booked appointments, and closed deals. Importing those outcomes into Google Ads lets reporting and bidding reflect lead quality instead of raw form fills.

How long does a Google Ads audit take?

It depends on account size and history. A small, single-service account can be reviewed fairly quickly, while multi-location or multi-service accounts with years of history take longer to audit properly.

Should I pause campaigns during an audit?

Usually not. Pausing resets momentum and removes the data you need to evaluate. Fix urgent leaks, such as obviously irrelevant spend or broken tracking, while the rest of the audit continues.

Stop Paying for Clicks You Cannot Explain

Every Google Ads account accumulates small problems over time.

A conversion action that double counts. A setting nobody reviewed. A search term that has been quietly spending for months.

The question is not whether your account has leaks.

It is whether you know where they are and which ones to fix first.

A strong Google Ads audit follows a clear order: verify tracking, tighten settings, clean up search terms, sharpen ads, align bidding with real lead value, and make sure every click lands on a page built to convert.

That is how paid search stops being a monthly expense you hope is working and becomes a lead generation channel you can measure and grow.
