When every click costs you money, you want to achieve your objectives with each click. Even with the most sophisticated PPC campaigns, ad performance can start to dwindle with time. Costs may rise, ads can become stagnant, and conversions can crawl to a standstill.
This is where a PPC audit comes in. A PPC audit is the meticulous evaluation of an ad account to identify the key drivers of performance, the key budget drainers, and the areas that can be optimized. This guide will walk you through every step required in inspecting, troubleshooting and resolving campaign issues.

What Is A PPC Audit?
A PPC audit is a comprehensive evaluation of your paid search advertisements to identify strengths, weaknesses and areas for improvement. It consists of reviewing the account’s structure, the hierarchy of campaigns and ad group structure, audience targeting, creatives, keywords, bidding tactics and the overarching systems in place for tracking to ensure alignment with the campaign objectives.
You can view it as a competitive PPC search audit for your account. You have set your benchmarks and competitive performance ranges, assessed performance, and based your verdict and strategy for improvement, relying on data.
With a well-structured PPC audit, you can uncover wasted ad spend, improve quality scores, and increase ROI.
Why Should You Conduct a PPC Audit Regularly?
With regular PPC ads audits, you can spot problems early and keep your ads performing at their best. You should conduct a PPC audit regularly to:
1. Maximize ROI And Reduce Costs
A PPC audit helps you find relevant keywords, ad variations, or audiences that spend your budget without bringing results. If a keyword gets clicks but no conversions, pause or remove it so you can focus your budget on terms that actually perform.
2. Stay Ahead of the Competition
A competitive PPC audit helps you monitor shifts in auction activity, competitor activity, and overall industry movement.
It is possible to take action to maintain and improve your competitive position, for example, by changing your bids or enhancing ad copy, if Auction Insights indicates a competitor is acquiring impression share on your priority keywords.
3. Optimize Bidding Strategies
The audit will determine if your current bidding strategy is still optimal. A common example is with manual CPC bidding.
If your account has enough conversion data, you might try switching from manual to Target CPA or Target ROAS bidding. This will improve efficiency for the account while still preserving effectiveness.
4. Understand Performance Over Time
If you review historical PPC ad campaigns data, you can identify patterns. For example, if your click-through rate drops during certain months, you can plan seasonal promotions or adjust targeting in advance.
5. Learn About The Target Audience
In your PPC software, your audit will show you which demographics, locations, and devices bring in the best results. You can then allocate more budget to the highest-performing segments.
6. Measure Against Competitors (Auction Insights)
When you look at Auction Insights, you can see how often your ads show up next to your competitors’ ads and where you usually rank compared to them.

7. Prevent Wasted Spend
Sometimes ad budgets get drained by broad match keywords, poor-quality placements, or even campaigns competing against each other. A PPC audit helps you spot these issues so you can stop the waste and use your budget where it actually works.
8. Collect Data for Reports
When you audit your campaigns, it becomes much easier to create clear reports for your team or clients. You will have reliable numbers that show what’s actually driving results and exactly where your budget is being spent.
Google Ads Help Center recommends using industry benchmarks as reference points when assessing performance.
What Should You Do Before Starting a PPC Audit?
Prior to initiating the audit, it is best to have a PPC audit checklist so you can get the actionable insights:
1. Defining Audit Goals
Deciding what to accomplish is a prerequisite. Reducing the cost per acquisition, improving the click-through rate, increasing the quality score, or recognizing the low-performing keywords are some possible objectives. A defined goal allows the audit to remain concentrated.
2. Collect Data And Reports
You should download the reports of your ads from Google Ads, Microsoft Ads, or any other ad running platforms. Do not forget to capture the required data on impressions, clicks, CTR, conversion rate, cost per conversion and quality score. If you are retrieving and analyzing the data for at least the last 90 days, the insights will reveal patterns and trends that are much clearer.
3. Set KPIs And Industry Comparatives
Setting these and benchmarking them against the averages from the industry will inform how you’re performing.
For instance, within multiple industries, the average click-through rate for search ads is approximately 6.66%, and their average conversion rate is near 7.52%.
4. Set and Review Your Budgets
Before commencing your PPC ad audit, ensure to study your budget allocation first within campaigns. This helps you assess whether your best campaigns are actually being funded more than their budget, or if poor-performing ones are eating up your ad spend budget.

What Are the Steps to Conduct a PPC Audit?
Following clear and definitive instructions works wonders for any PPC campaign. Therefore, this PPC audit guide breaks down every step of the campaign for you.
1. Review Your Conversion Tracking Configuration
In any audit, the first step is to check how your conversion tracking is working. Your audit only makes sense if you are basing the PPC evaluation on correct data, so ensure to regularly check if your conversion and tracking are working.
In your Google Ads account and Google Analytics, check if your major conversions, for example, purchases, form fills, and call tracking, are firing as expected.
Verifying for outdated goals or duplicate conversions is also possible. High click-through rates coupled with very low conversions mean that you are either under-tracking or over-tracking.
2. Review Account/Campaign Settings
Your account structure and settings can impact performance more than you might expect. Go through your campaigns to check:
- Location targeting: Is your marketing targeting the appropriate geographies?
- Language settings: Is your audience aligned with your intended communication language?
- Ad scheduling: Are the ads shown during the times your audience is most likely to be engaged?
- Network settings: Is your targeting intentional for Display Network, Search Network, or both?
If you find out that your ads are running in regions where you don’t sell or during hours when your audience is inactive, you can cut waste immediately.
3. Review Keywords & Search Terms
Your keyword list determines who sees your ads. Start by checking keyword match types to ensure you are not overusing broad match, which can attract irrelevant clicks.
Next, open your Search Terms Report to see the actual queries triggering your ads. Eliminate phrases that have low relevance and add high-converting phrases as exact or phrase match keywords.
Only consider CTR and conversion rate to assess keyword-level KPIs. For instance, if a keyword fails to meet a 2% CTR as well as zero in conversion after more than 200 clicks, then that keyword may be better off untargeted.
In 2025, Google Ads continues to lead the PPC landscape, holding a commanding 69% share of the market and powering campaigns for roughly 8 in 10 businesses worldwide. Around 63% of internet users have interacted with a Google ad, and on average, companies see a $2 return for every $1 they invest—a solid 200% ROI.
4. Inspect Advertisement Copy & Visuals
Your Quality Score and CTR are heavily dependent on your advert copy. Audit your adverts and evaluate:
- Keyword response adverts: Are keywords clear, articulate the benefits, and gain attachment to the selected keyword?
- Call-to-action element: Does it indicate the subsequent action the user is supposed to take?
- A/B tests: Are you conducting regular tests to determine winning versions?

5. Adjust Advertisement Assets (Extensions)
Callouts, snippets, and page sitelinks are all examples of ad extensions that improve the relevance and visibility of an ad. Ensure that all your ad assets are updated and that all your advertising campaigns are populated with relevant extensions.
If you have location extensions and your address has changed, be sure to update them to avoid confusion.
6. Review Landing Pages
Your page experience has a significant effect on your conversion and Quality Score. In your case, it is:
- Your page load speed: Aim for below three seconds.
- Ad Relevance: Is the content of the page aligned with the promise of the ad?
- Mobile friendliness: The majority of PPC clicks originate from mobile devices these days.
- Clear CTAs: Ensure the next actions to be taken are clear.
7. Review Bidding Strategy & Budget
Check your bidding PPC strategy to make sure it aligns with your goals. If the bidding strategy aligns with your goals and you have sufficient data, consider using automated strategies like Target CPA or Target ROAS.
Assess the budget distribution as well. Well-performing campaigns should have enough daily budget to capture demand. Poor-performing campaigns should have their budget reduced or be paused altogether.
As an illustration, if your cost per conversion stands at $40 but your goal is $25, adjusting budget allocation to more successful campaigns will enable you to achieve your target.
8. Calculate ROI & ROAS
An audit on PPC is centered on profitability.
ROI, or Return on Investment, calculates the profit a business makes from the designated ad spend. In contrast, ROAS, or Return on Advertising Spend, describes the profit that is made to the cost incurred, in other words, the profit incurred on the spend made on advertising.
Take, for instance, an advertising spend of 1,000 USD and 4,000 USD in revenue generated. This gives an ROI of 1,000, and a profit of 3000, making the ROAS 4:1. Gaining an understanding of these KPI’s will help in identifying the scalable campaigns.
9. Review of Targeting Options
Analyze the demographics of the users, in market segments, audience retention and cross-device user classification. Taking mobile conversion for example, if a campaign is generating a good number of conversions on mobile devices, the mobile bid strategy could be optimized to be more aggressive to capture that conversion traffic.
10. Check for Outdated Scripts/Rules
In the event that you automate Google Ads using scripts and rules, take some time to reassess them to make sure that your structure hasn’t changed. Google Ads automations that are not supervised can be detrimental to performance.
What Tools Can Help You Run a PPC Audit?
Completing a PPC audit manually is within reach for most people, but a well-structured set of tools can deliver improved speed and precision. Here are some of the most trusted PPC audit tools.
1. Google Ads Editor
Google Ads Editor is a Google-provided free desktop application that enables users to make offline campaign edits. Users can make bulk edits, review and adjust bid settings, and check the overall account structure without logging into the online interface. It is helpful for a free PPC audit and auditing large-scale accounts with numerous campaigns.
2. SEMrush / Ahrefs
These platforms provide competitive paid search audit insights. You can see which keywords your competitors are bidding on, the ad copy they are using, and how much traffic they are generating from paid search. This helps you spot gaps in your campaigns and new opportunities to target.
3. Google Analytics
Google Analytics shows how PPC traffic behaves once it lands on your website. By linking Google Ads and Analytics, you can see bounce rates, session duration, and conversion paths. If your bounce rate is high or session time is low, it may indicate a mismatch between your ads and landing pages.
4. Optmyzr or Supermetrics
Optmyzr provides automated PPC auditing tools that flag underperforming keywords, ads, and targeting settings. Supermetrics helps you pull PPC data into reports and dashboards so you can track performance trends over time. Both can save time by automating parts of the audit process.
