You’ve got a nagging feeling about your Google Ads account. Maybe your cost per lead has quietly crept up over the past few months. Maybe your click-through rates have flatlined, or your campaigns are running on autopilot and nobody’s looked under the hood in a while. That feeling is usually right.
A proper PPC audit is the fastest diagnostic tool you have. It reveals exactly where your budget is bleeding, which settings are quietly sabotaging performance, and where there are real gains sitting untouched. The problem is that most “PPC audit checklists” floating around online are either too shallow to be useful or built for enterprise advertisers managing six-figure monthly budgets.
This guide is built differently. It’s designed for local business owners and the agencies serving them — the ones who need every dollar to produce a measurable return. As a Google Premier Partner agency, Clicks Geek has run hundreds of these audits across industries, and these are the eight areas that consistently reveal the most waste and the most opportunity.
Each strategy below covers the specific problem it solves, how to actually implement it, and pro tips from real campaign management experience. Whether you’re auditing your own campaigns or evaluating work done by an agency, this framework gives you everything you need to find hidden waste and turn your ad spend into actual revenue.
1. Tear Apart Your Campaign Structure First
The Challenge It Solves
Poor campaign structure is the foundation of almost every underperforming account. When dozens of loosely related keywords get lumped into a single ad group, Google struggles to match your ads to the right queries with the right message. The result is lower ad relevance, weaker Quality Scores, higher costs per click, and ad copy that speaks to no one in particular.
The Strategy Explained
Start your audit at the top of the hierarchy. Look at how campaigns are segmented — are they organized by service line, location, match type, or some combination? Then go one level deeper into ad groups. The rule of thumb is tight thematic grouping: each ad group should contain keywords so closely related that a single set of ads speaks directly to all of them.
A plumber running one ad group called “Plumbing Services” with 40 keywords is a red flag. That structure makes it nearly impossible to write ad copy that’s relevant to every query, and it gives you almost no granular control over bids or budgets. A well-structured account separates “emergency drain cleaning,” “water heater installation,” and “sewer line repair” into distinct ad groups with tailored messaging for each. If your PPC campaigns aren’t profitable, poor structure is often the root cause.
Implementation Steps
1. Pull a full list of all campaigns and ad groups and map them visually. Identify any ad group containing more than 10-15 keywords and flag it for review.
2. Check whether campaigns are logically segmented by service, product, or geography. If your highest-value services are lumped in with low-margin offerings, separate them so you can control budget allocation independently.
3. Audit for single keyword ad groups (SKAGs) or tightly themed ad groups and verify that the ad copy in each group directly references the core theme of its keywords.
Pro Tips
Don’t restructure everything at once. Prioritize your highest-spend campaigns first. Rebuilding structure mid-flight can temporarily disrupt performance, so do it methodically and give new ad groups a few weeks to gather data before drawing conclusions.
2. Run a Ruthless Negative Keyword Purge
The Challenge It Solves
Many local businesses discover, often with some shock, that a meaningful portion of their ad spend is going to searches that have nothing to do with their services. Without a maintained negative keyword list, broad and phrase match keywords will trigger ads for tangentially related or completely irrelevant queries. That’s real money spent on clicks that were never going to convert.
The Strategy Explained
The search term report in Google Ads is your primary tool here. It shows you the actual queries that triggered your ads and generated clicks. Your job is to go through this report systematically and identify patterns: informational searches from people not ready to buy, competitor brand names you don’t want to pay for, geographic terms outside your service area, and job-seeker searches like “plumber jobs near me.” If your ads are spending too much with no results, irrelevant search terms are often a major contributor.
Negative keywords should be built at two levels. Campaign-level negatives are specific to one campaign’s context. Account-level negative keyword lists, applied across multiple campaigns, are more efficient for recurring irrelevant terms that apply broadly to your business.
Implementation Steps
1. Pull the search term report for the last 90 days. Sort by cost and look at the highest-spend queries first. Any irrelevant term that has consumed budget without producing a conversion is a candidate for a negative.
2. Look for patterns, not just individual terms. If “DIY” appears in multiple queries, add it as a broad match negative. If “free” or “cheap” don’t align with your positioning, add those too.
3. Build a shared negative keyword list in the Google Ads library and apply it at the account level for terms that are universally irrelevant to your business.
Pro Tips
Be careful not to over-negative. Adding too many negatives can restrict reach on legitimate queries. When in doubt, check the query’s conversion history before adding it as a negative. A term might look irrelevant but could have converted before.
3. Audit Your Conversion Tracking for Accuracy
The Challenge It Solves
Conversion tracking errors are arguably the most damaging issues you can find in an audit because they corrupt the data that your entire optimization strategy depends on. If your tracking is double-counting form fills, missing phone call conversions, or firing on the wrong page, every decision you make based on that data is built on a lie. Smart bidding strategies are especially vulnerable — they need accurate conversion data to function correctly.
The Strategy Explained
This audit step requires you to verify that every conversion action you care about is firing correctly, once, and only once. The key conversion actions for most local businesses are phone calls (both from ads and from the website), form submissions, and in some cases, chat initiations or appointment bookings.
Use Google Tag Assistant or the Google Ads conversion tracking diagnostics to verify that tags are firing. Check for duplicate conversion actions, which commonly happen when both Google Ads and Google Analytics are importing the same goal. Understanding what a good conversion rate looks like helps you benchmark whether your tracking data even makes sense in the first place.
Implementation Steps
1. Open your Conversion Actions in Google Ads and review every item in the list. Look for duplicate names or overlapping actions that could be counting the same event twice.
2. Test each conversion action manually. Submit a test form, make a test call, and confirm the conversion fires in the interface. Use Google Tag Assistant to verify tag behavior in real time.
3. Check your attribution model. Last-click attribution is still common but may undervalue upper-funnel touchpoints. Consider whether data-driven attribution makes more sense for your account volume.
Pro Tips
If you’re running smart bidding and your conversion data has been inaccurate, correcting the tracking won’t instantly fix performance. Give the algorithm several weeks of clean data to recalibrate after you’ve resolved tracking issues before making major bid strategy changes.
4. Evaluate Ad Copy Relevance and Testing Cadence
The Challenge It Solves
Ad copy that doesn’t match what a searcher is looking for produces lower click-through rates, weaker Quality Scores, and higher costs per click. Beyond relevance, many accounts fall into a “set it and forget it” pattern where the same ads run for months or years with no testing, no iteration, and no learning. Stale copy means you’re leaving performance improvements on the table.
The Strategy Explained
Responsive Search Ads (RSAs) are now the standard format in Google Ads, allowing up to 15 headlines and 4 descriptions. Google recommends using all available headline and description slots to give the machine learning system maximum material to work with and find the best-performing combinations. During your audit, check how many slots are actually being used and whether the copy in those slots is genuinely differentiated.
Beyond RSAs, look at ad strength ratings in the interface. “Poor” or “Average” ratings are a signal that your copy needs work. But don’t rely solely on ad strength — check actual CTR and conversion rate data by ad to identify real performers versus underperformers. Professional PPC campaign optimization services can accelerate this testing process significantly.
Implementation Steps
1. Review every active RSA in your account. Flag any that have fewer than 10 headlines or 2 descriptions — these are under-utilizing the format. Add variations that speak to different value propositions: speed, price, expertise, local presence.
2. Check that headlines in each ad group reference the core keyword theme. Generic headlines like “Get Started Today” or “Learn More” that appear in every ad group are missed opportunities for relevance.
3. Look at the date each ad was last modified. If nothing has changed in over 90 days, that’s a signal there’s no active testing happening. Set a reminder to rotate in new headline variations quarterly.
Pro Tips
When writing new headline variations, think about the different reasons someone might click. Some searchers respond to social proof, others to urgency, others to specificity. Cover multiple angles across your 15 headline slots rather than repeating the same message in different words.
5. Dissect Your Bidding Strategy Against Actual Performance
The Challenge It Solves
Bidding strategy mismatches are a common source of wasted spend. Accounts using automated smart bidding without sufficient conversion data are essentially asking the algorithm to optimize in the dark. Conversely, accounts that have plenty of conversion data but are still on manual CPC are leaving efficiency gains untouched. The right bidding strategy depends on your specific situation, not a default setting.
The Strategy Explained
Google’s own documentation recommends having at least 30 conversions within a 30-day period before switching to Target CPA or Target ROAS smart bidding strategies. Below that threshold, the algorithm doesn’t have enough signal to make reliable predictions, and performance can become erratic. If you’re trying to increase ROAS in your PPC campaigns, getting the bidding strategy right is essential.
During your audit, look at each campaign’s conversion volume over the past 30 days alongside its current bid strategy. The goal is alignment: high-volume campaigns with stable conversion data are strong candidates for smart bidding. Low-volume or newly launched campaigns need a different approach.
Implementation Steps
1. Pull a campaign-level report showing conversions over the last 30 days. Segment by bid strategy to see which campaigns are on manual CPC, maximize conversions, target CPA, or target ROAS.
2. For campaigns on Target CPA or Target ROAS with fewer than 30 monthly conversions, evaluate whether the strategy is actually performing or whether the algorithm is making poor decisions due to thin data.
3. Check your target CPA or ROAS values against actual historical performance. If your target CPA is set significantly below your historical average, you may be constraining the algorithm and limiting impression share.
Pro Tips
When transitioning to a new bid strategy, use the “experiment” feature in Google Ads to run a split test rather than switching everything at once. This protects your baseline performance while you gather evidence that the new strategy works in your specific account.
6. Inspect Landing Page Alignment and Load Speed
The Challenge It Solves
Getting someone to click your ad is only half the battle. If they land on a page that doesn’t match what the ad promised, or that takes too long to load on mobile, you’ve paid for a click that was never going to convert. Landing page issues are one of the most overlooked sources of wasted ad spend because they live outside the Google Ads interface and often fall through the cracks between marketing and web teams.
The Strategy Explained
Audit the connection between your ad messaging and your landing page content. If your ad headline says “Same-Day AC Repair in Dallas,” your landing page should prominently feature same-day service and Dallas-specific messaging — not a generic homepage about your HVAC company‘s history. The more specific the match, the higher your conversion rate tends to be.
On the technical side, use Google PageSpeed Insights (a free tool) to benchmark your landing page load times. Google has documented that mobile pages loading in over three seconds see significantly higher bounce rates. If you’re struggling with not enough website traffic from ads, slow landing pages could be compounding the problem by driving away the visitors you do get.
Implementation Steps
1. Click through every destination URL in your active campaigns. Verify the page loads correctly, matches the ad’s offer, and has a clear, prominent call to action above the fold.
2. Run each landing page URL through Google PageSpeed Insights. Note the mobile score specifically. Pages scoring below 50 on mobile are worth prioritizing for technical improvements.
3. Audit your forms and CTAs for friction. Count the number of form fields — every unnecessary field reduces completion rates. Check that phone numbers are click-to-call on mobile and that your primary CTA is visible without scrolling.
Pro Tips
If you’re sending all traffic to your homepage, that’s almost always the wrong move. Dedicated landing pages built for specific ad groups consistently outperform generic pages. Even a simple, focused page with a clear headline, three bullet points, and a form will typically outperform a complex homepage with navigation and multiple competing CTAs.
7. Analyze Geographic and Dayparting Settings
The Challenge It Solves
Two of the most commonly misconfigured settings in local business Google Ads accounts are location targeting and ad scheduling. These settings directly control who sees your ads and when, yet they often get set during initial campaign setup and never revisited. The result is budget spent on the wrong people at the wrong times.
The Strategy Explained
Start with location targeting. Google Ads defaults to “Presence or interest” for location targeting, which means your ads can show to people who are interested in your target area but physically located elsewhere. For most local service businesses, this is the wrong setting. You want “Presence” only, which restricts ads to people physically located in your service area. Mastering local search advertising management means getting these foundational settings right from the start.
On the scheduling side, pull an hourly performance report broken down by day of week. Look for patterns: hours with high spend and low conversion rates, days where your cost per lead is significantly above average, or times when you’re paying for clicks when your business isn’t even open to answer the phone.
Implementation Steps
1. Navigate to each campaign’s location settings and verify the targeting option is set to “Presence” rather than “Presence or interest.” This single change can meaningfully improve geographic relevance for local advertisers.
2. Pull a “Day and hour” segment report for the last 90 days. Sort by cost and identify time blocks with high spend but low conversion activity. Apply negative bid adjustments or exclusions to those windows.
3. Check your location bid adjustments. If certain cities or zip codes within your service area are converting at a significantly higher or lower rate than average, apply bid adjustments to reflect that performance.
Pro Tips
Be careful about completely excluding time periods based on short data windows. A time slot might look weak over 30 days but perform differently across seasons. Use 90-day data minimums before making exclusions, and revisit those settings quarterly.
8. Benchmark Your Quality Scores and Fix the Weak Links
The Challenge It Solves
Quality Score is Google’s rating of the relevance and quality of your keywords, ads, and landing pages. It directly influences both your ad rank and your cost per click. A low Quality Score means you’re paying more than competitors to show in the same position. Improving Quality Score is one of the few levers in PPC that can lower your costs while maintaining or improving your visibility.
The Strategy Explained
Quality Score is calculated based on three sub-components visible in the Google Ads interface: expected click-through rate, ad relevance, and landing page experience. Each component is rated as “Above average,” “Average,” or “Below average.” This breakdown tells you exactly where to focus your effort rather than guessing. For a deeper dive into this topic, our guide on how to improve Quality Score in Google Ads walks through each sub-component in detail.
During your audit, add Quality Score and its three sub-components as columns in your keyword view. Filter for keywords rated 5 or below and look at which sub-component is dragging the score down. Below-average landing page experience points to the fixes covered in Strategy 6. Below-average ad relevance points back to the structure and copy issues in Strategies 1 and 4. Below-average expected CTR often means your ad copy isn’t compelling enough for the query.
Implementation Steps
1. In the Keywords view of Google Ads, add columns for Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. Export this data for all active keywords.
2. Filter for keywords with Quality Score of 5 or below and segment by which sub-component is rated “Below average.” This creates a prioritized fix list rather than an overwhelming overhaul.
3. Address the most impactful issues first: keywords with high spend and low Quality Score should take priority over low-spend keywords with the same problem. A one-point Quality Score improvement on a high-volume keyword delivers more cost savings than the same improvement on a rarely-triggered term.
Pro Tips
Quality Score is calculated at the keyword level but influenced by factors at the ad group and landing page level. If multiple keywords in the same ad group have below-average ad relevance, the fix is at the ad group level, not the individual keyword level. Tightening the theme of the ad group and improving copy relevance will lift scores across all keywords in it simultaneously.
Pulling It All Together: Your PPC Audit Action Plan
Running through all eight of these strategies in a single sitting can feel overwhelming. The good news is that you don’t have to fix everything at once. Prioritizing by impact makes the process manageable and ensures you’re addressing the issues that matter most first.
Start with conversion tracking. If your data is inaccurate, every other optimization you make is built on a flawed foundation. Get that right before touching anything else. From there, move to campaign structure and keyword hygiene — these structural fixes create the conditions for everything else to work better. Then work through bidding strategy, ad copy, landing pages, geographic settings, and Quality Score in that order.
Set a recurring quarterly audit schedule. PPC accounts drift over time. Search behavior changes, competitors adjust their strategies, and settings that made sense six months ago may no longer be optimal. A quarterly review using this checklist keeps performance from quietly eroding between major campaigns.
Know when to bring in professional help. Some of these fixes are straightforward. Others, like diagnosing complex conversion tracking issues or rebuilding account structure without disrupting performance, benefit from experienced hands. If you’re spending meaningful money on Google Ads and not confident in what you’re seeing, a professional audit can pay for itself quickly.
If you want to see what this would look like for your specific account, Clicks Geek offers professional PPC audits backed by Google Premier Partner expertise. We’ll walk you through exactly what’s working, what’s wasting budget, and what a realistic improvement plan looks like for your market.
