How to Audit Your Google Ads Account: A Step-by-Step Guide That Actually Works
If you’ve been running Google Ads for a while, you’ve surely experienced this scenario where you sit with “average” stats on the screen. You see nothing wrong, but something tells you it’s just not feeling right. One side is spend rising, on the other – the same number of conversions.
You don’t see any big changes in your ads or your keywords, and you don’t seem to find anything to adjust that should make it better. That means it’s probably time to do a Google Ads audit.
A real audit should not only help you identify and pause a few keywords but also give you a full understanding of your account. It’s about looking for any issues with the campaign structure or targeting and reviewing ad copy and tracking of campaign metrics to spot areas where money is being wasted. This way, you will be able to quickly address those areas before they result in significant money losses.
In this blog, you will find all the necessary components for performing a complete Google Ads audit. No jargon, just a practical checklist you can actually use today.
Why Bother With a Google Ads Audit in the First Place?
Here’s the truth. A majority of the ecommerce retail accounts are operating as an autopilot system. An operator was responsible for establishing advertising campaigns a month ago (even a year ago), and since then no one has been involved in revising and optimizing the campaigns.
As things have changed with time, some problems are common and easily foreseeable to the industry. Old keywords, which brought conversions, become less helpful. Banners are just copying old content without any new elements. The budget is being poured into too many campaigns that are not bringing you any sales, and you don’t realize.
A Google Ads audit covers all of this. If it’s done in the right way, it tells you exactly what’s working, what’s wasting money, and what to fix first.
Step 1: Check Your Account Structure
Start at the top. Open your campaigns and ask yourself: does this structure actually make sense for how customers shop?
For ecommerce accounts especially, campaigns should be organized around product categories or profit margins, not just “Shopping” and “Search” as one giant bucket. If your best sellers and your slow movers are sitting in the same campaign with the same budget, that’s a red flag.
A few things worth checking here:
- Are campaigns grouped logically (by category, brand, or margin)?
- Do ad groups contain tightly related keywords, not a mixed bag of everything?
- Is naming consistent enough that you (or anyone on your team) can understand what’s running at a glance?
Messy structure isn’t just annoying. It actively hurts performance because Google’s algorithm struggles to optimize scattered, poorly grouped campaigns.
Step 2: Dig Into Keyword Performance
This is where a lot of Google Ads mistakes hide. Extract your search terms report and look at what’s actually triggering your ads. Not just the keywords you originally added.
You’ll usually find three things:
- Keywords that are burning budget with zero conversions.
- Search terms that should be added as exact negatives.
- Winning keywords that deserve a bigger chunk of your budget.
| What to Look For | Why It Matters |
|---|---|
| High spend, low conversions | Indicates wasted budget and may require pausing, restructuring, or optimizing the campaign |
| Broad match with no negative keywords | Can allow irrelevant search queries to trigger ads and consume budget |
| Low impression share on top keywords | May indicate lost visibility to competitors and potential opportunities to improve bids, budgets, or ad relevance |
| High CTR, low conversion rate | Often points to a landing page, offer, or post-click experience issue rather than a keyword problem |
Don’t just go through this report once. You must ideally review the search terms every couple of weeks, not once a quarter.
Step 3: Review Your Quality Score
Your Google Ads quality score decides the cost per click and your ad rank. This means it’s a critical component and should have a dedicated section in any audit.
Google’s quality score is calculated as an average of three elements: estimated click-through rate, ad relevance, and landing page experience. If your score keeps falling, it likely means that there is a combination of problems in these three areas.
For example, maybe your ad copy is no longer relevant. Or your landing page is not aligned with the ad message.
Quick reality check: Is your ad title actually reflecting what can be expected on the landing page? Let’s say a customer looking for wireless earbuds for less than $50 lands on a generic home page. This will result in disappointment and a potential loss of business.
Step 4: Audit Your Ad Copy and Creative
Read your Ads from the buyer’s perspective. Don’t just read from the marketing point of view.
Ask yourself:
- Does the text highlight the benefits of your product or is it just describing it?
- Are you utilising all types of ad extensions – sitelinks, callouts, or structured snippets?
- Is there a specific, direct call to action rather than just a generic “Shop Now”?
- Have you developed at least 3-4 different headlines for each ad group?
One of the big mistakes made with Google Ads that is overlooked easily is the use of static creative material. Nothing “breaks” when ads are not refreshed. And hence the performance of the campaign slowly decreases. Sometimes advertisers will attribute slow performance to market fluctuations rather than examining what could be wrong with the ad.
Step 5: Confirm if Conversion Tracking is Accurate
Honestly, this step alone can save you more money than anything else on this list. If your conversion tracking is broken or inflated, every optimization decision you make afterward is built on bad data.
Go through this quickly:
- Are you tracking the right actions (purchases, not just add-to-cart)?
- Is there duplicate tracking firing on the same event?
- Does your Google Ads conversion count roughly match your actual order numbers in your store backend?
If there’s a big gap between the two, stop everything else and fix tracking first. There’s no point optimizing bids around numbers that aren’t real.
Step 6: Look at Budget Allocation and Bidding Strategy
Once structure, keywords, and tracking are solid, budgets are the next lever. Are you funding your best-performing campaigns adequately, or is spend spread evenly regardless of results?
Also worth checking is whether your bidding strategy is still the right fit. A store that started with manual CPC months ago might genuinely benefit from switching to Target ROAS now that there’s enough conversion history for Google’s algorithm to work with.
This single step is often where the biggest Google Ads optimization gains come from, simply moving money from what isn’t working to what is.
A Simple Google Ads Checklist to Keep Handy
- Account and campaign structure reviewed
- Search terms report checked for waste and negatives
- Quality Score reviewed campaign by campaign
- Ad copy refreshed, and extensions maximized
- Conversion tracking verified against real sales data
- Budget reallocated toward top performers
- Landing pages matched to ad messaging
Run through this Google Ads Checklist monthly, and you’ll catch small issues long before they become expensive ones.
The Real Goal: Improve ROAS, Not Just Cut Down Spends
It’s worth saying this clearly. The point of a Google Ads audit isn’t just cutting down costs. It’s making sure every dollar you spend is used efficiently. Sometimes that means cutting waste. Other times it means putting more budget behind something that’s already converting well.
If you focus only on cutting, you’ll shrink your account. If you focus on reallocating toward what works, you actually improve ROAS while growing.
Ready to Put This Into Practice?
If you follow this process step by step, it will take only 1-2 hours to audit your own account. Set a recurring reminder, block time on your calendar, and work through each section above. Your future ad spend (and your ROAS) will thank you. You can also contact a Google Ads Management service provider who can help you with auditing and managing your Google Ads account.
Frequently Asked Questions
1. How often should I audit my Google Ads account?
For most ecommerce accounts, a complete Google Ads audit every 60 to 90 days is a practical approach. However, reviewing search terms and budget allocation every two weeks can help identify wasted spend and performance issues earlier.
2. What’s the biggest mistake people make during a Google Ads audit?
One of the biggest mistakes is failing to verify conversion tracking. Every other part of the audit relies on accurate conversion data, so tracking should be checked at the beginning rather than treated as an afterthought.
3. Can a low Quality Score really affect my budget?
Yes. A low Quality Score can increase the cost per click required for your ads to achieve similar positions. As a result, advertisers with comparable bids may pay significantly different amounts depending on factors such as ad relevance, expected click-through rate, and landing page experience.
4. Do I need special tools to run a Google Ads audit?
No. The Google Ads platform provides access to essential data such as search terms, Quality Score information, and conversion performance. Third-party tools can make the auditing process faster and more efficient, but they are not required to conduct a thorough audit.
