A Google Ads audit is a systematic review of your account to find what is working, what is wasting money, and what opportunities you are missing. Whether you run the audit yourself or hire someone to do it, understanding what the process covers helps you make better decisions about your advertising.
This guide explains what a thorough Google Ads audit includes, why each area matters, and what to do with the findings.
Why You Need a Google Ads Audit
Google Ads accounts accumulate inefficiencies over time. Campaigns that performed well six months ago may be bleeding money today. Settings that made sense at launch may be wrong for your current goals. Features Google added (or changed) since you last reviewed your account may be costing you without your knowledge.
The most common triggers for an audit include declining performance (rising cost per conversion, dropping ROAS), taking over an account from a previous manager or agency, onboarding a new client, or simply not having reviewed the account in more than 90 days.
A comprehensive audit typically uncovers 15 to 30 percent in recoverable waste and identifies opportunities that could improve conversion volume by 20 to 50 percent. Those are not exaggerations — they are averages from the hundreds of audits I have conducted.
Conversion Tracking Review
This is always the first thing to check because everything else depends on it. If your conversion tracking is broken, every metric in your account is unreliable.
Are conversions being recorded? Check Settings > Conversions. Verify that your primary conversion actions are active and receiving data. If a conversion action shows “No recent conversions” for more than 7 days, something is broken.
Are you tracking the right actions? Every conversion action should map to a meaningful business outcome. Form submissions, phone calls, purchases — these are real conversions. Page views, scroll depth, and time on site are engagement metrics, not conversions. Including them as conversion actions corrupts your smart bidding.
Is there double-counting? If you have both Google Ads native conversion tracking and a GA4 import for the same action, you are counting each conversion twice. Check for overlapping conversion sources and set secondary conversions to “Observation” mode.
Are conversion values accurate? For ecommerce, revenue values should flow dynamically from your checkout. For lead generation, assign realistic values based on your average deal size and close rate. A lead worth $5,000 in lifetime value with a 10 percent close rate should have a conversion value of $500.
Is offline conversion tracking in place? If your sales process involves phone calls, in-person meetings, or a sales team, you need offline conversion data flowing back to Google Ads. Without it, you are optimizing for leads, not revenue.
Campaign Structure Analysis
How your campaigns are organized determines how effectively Google can optimize your spend.
Campaign segmentation. At minimum, branded and non-branded search should be in separate campaigns. Ideally, campaigns are segmented by service line, product category, or funnel stage. Each campaign should have a clear purpose and target audience.
Budget allocation. Compare budget distribution to performance distribution. If Campaign A generates 60 percent of your conversions but only gets 30 percent of the budget, you have an allocation problem. Shift budget toward your highest-performing campaigns, not your highest-spending ones.
Campaign types. Review whether you are using the right campaign types for your goals. Search campaigns for intent capture, Performance Max for broad reach with automation, Shopping for ecommerce products, Display for remarketing. Each type serves a different purpose.
Too many or too few campaigns. A single campaign trying to do everything cannot optimize well. But 20 campaigns each getting $5 per day do not have enough data for smart bidding to learn. Find the balance: enough segmentation for control, enough consolidation for data volume.
Keyword and Search Term Analysis
Keywords are the foundation of Search campaigns, and they need regular maintenance.
Search Terms report. This is the most important report in the account. Review the actual queries triggering your ads. Flag irrelevant terms for negative keyword addition. Look for high-performing queries that deserve their own ad groups or campaigns.
Match type distribution. Check the balance between broad, phrase, and exact match. Heavy reliance on broad match without strong negative keyword lists leads to wasted spend. Heavy reliance on exact match limits your reach. A healthy account usually has a mix with broad match driving discovery and exact match driving efficiency.
Quality Score analysis. Review Quality Scores across your top keywords. Scores below 5 indicate a mismatch between keywords, ads, and landing pages. Low Quality Scores increase your cost per click — fixing them is often the fastest way to reduce costs without reducing traffic.
Keyword performance. Identify keywords that have spent significant budget without converting. If a keyword has spent 3x your target CPA without a single conversion, it needs to be paused or restructured. Also identify keywords with strong conversion rates that could benefit from increased bids or budget.
Ad Copy and Creative Review
Ads are your first impression. Weak ads waste clicks because they attract the wrong people or fail to compel the right people to click.
Responsive Search Ad (RSA) setup. Each ad group should have at least one RSA with 10 to 15 unique headlines and 4 descriptions. Check ad strength indicators — “Poor” and “Average” ads need attention. But do not optimize purely for ad strength; focus on conversion performance.
Message match. Compare each ad’s messaging to its landing page. If the ad promises a “Free Google Ads Audit” but the landing page talks about your full service menu, the disconnect kills conversions. Every ad should have a corresponding landing page that delivers exactly what the ad promised.
Extension utilization. Sitelinks, callouts, structured snippets, call extensions, and location extensions all improve ad real estate and click-through rate. An audit should verify that all relevant extensions are active and that the information is current.
Bidding Strategy Assessment
Bid strategy is one of the highest-leverage settings in the account.
Is the bid strategy appropriate for the campaign’s conversion volume? Smart bidding strategies (Target CPA, Target ROAS, Maximize Conversions) need at least 15 to 30 conversions per month to optimize effectively. Campaigns below this threshold may perform better with Manual CPC or Maximize Clicks.
Are targets realistic? A Target CPA set 50 percent below what the market supports will starve the campaign of impressions. Compare your targets to actual historical performance and set them at or slightly below your recent average, then optimize incrementally.
Portfolio bid strategies. For accounts with many small campaigns, portfolio bid strategies that pool conversion data across campaigns can improve performance. Check whether this approach makes sense for your account structure.
Landing Page and Conversion Flow
The audit is not complete without reviewing where ad traffic actually goes.
Landing page relevance. Each ad group should point to a landing page that directly matches the user’s search intent. Generic pages with multiple CTAs convert worse than focused pages with a single, clear action.
Page speed. Check mobile and desktop load times. Pages that take more than 3 seconds to load on mobile lose a significant percentage of potential conversions. Google PageSpeed Insights gives you specific recommendations.
Form and checkout review. Test the conversion flow yourself. Fill out the form or go through the checkout. Note any friction points: confusing fields, missing trust signals, slow load times, or broken form submissions.
Geographic and Audience Settings
Location targeting mode. Check whether campaigns use “Presence” (people in your location) or “Presence or interest” (people in or interested in your location). For most local businesses, “Presence” is the correct setting. “Presence or interest” can waste significant budget on people outside your service area.
Audience performance. Review how different audience segments perform. In-market audiences, remarketing lists, and customer match lists often have vastly different conversion rates. Use this data to adjust bids and targeting.
Device performance. Compare desktop, mobile, and tablet conversion rates and cost per conversion. If mobile converts at half the rate of desktop, consider bid adjustments or separate mobile campaigns with mobile-optimized landing pages.
What to Do With Audit Findings
An audit is only valuable if you act on the findings. Prioritize changes by impact and effort.
High impact, low effort (do this week): Add negative keywords, fix conversion tracking issues, adjust bid targets, pause wasteful keywords.
High impact, medium effort (do this month): Restructure campaigns, create new landing pages, implement server-side tracking, write new ad copy.
High impact, high effort (plan for next quarter): Build offline conversion pipeline, launch new campaign types, overhaul landing page design.

Frequently Asked Questions
How much does a Google Ads audit cost?
Professional Google Ads audits range from free (many agencies and freelancers offer complimentary audits as a lead generation tool) to $500 to $2,000 for a comprehensive paid audit with a detailed report and prioritized recommendations. Free audits are usually high-level and serve as a sales conversation starter. Paid audits are more thorough and typically include actionable implementation steps. Some consultants include the audit cost as a credit toward ongoing management if you decide to hire them.
What is included in a professional Google Ads audit?
A thorough audit covers: account structure (campaign and ad group organization), keyword analysis (match types, negative keywords, search term quality), ad copy review (relevance, extensions, testing history), bidding strategy assessment, conversion tracking verification, landing page alignment, audience targeting review, budget allocation analysis, and competitive positioning through Auction Insights. The deliverable should be a prioritized list of findings with specific recommendations, not just a list of problems without solutions.
Can I audit my own Google Ads account?
Yes, and you should do regular self-audits even if you work with an agency or freelancer. Start with the search terms report (look for irrelevant queries), check conversion tracking accuracy (compare Google Ads data with GA4 and your CRM), review Quality Scores (anything below 5 needs attention), and analyze your top-spending keywords to ensure they are generating profitable conversions. A fresh outside perspective catches things you have become blind to, but regular self-audits prevent problems from growing between professional reviews.
How often should I get a Google Ads audit?
Get a comprehensive professional audit at least twice a year, or whenever you experience a significant performance change (positive or negative). If you are spending over $10,000 per month, quarterly audits are worthwhile because the potential for waste is higher. Between formal audits, run monthly self-checks on search terms, conversion tracking, and budget allocation. Any time you take over an account from another manager or agency, start with a full audit before making changes.
What are the most common problems found in Google Ads audits?
The top five issues found across most audits are: inadequate negative keyword lists (wasting budget on irrelevant searches), conversion tracking errors (tracking wrong events or missing conversions), poor campaign structure (too many keywords in one ad group, reducing ad relevance), underutilized ad extensions (missing sitelinks, callouts, or structured snippets), and misaligned bidding strategies (using Smart Bidding without enough conversion data). Most accounts have at least two or three of these problems, even those managed by experienced marketers.
