How to Audit Google Ads Account?

Learn how to audit Google Ads account performance with a step-by-step guide to check campaigns, keywords, ads, and improve ROI and ad optimization.

You log into your Google Ads account. You see the numbers: Impressions, Clicks, Cost. The graph is wobbling along, but is it actually healthy? It’s the digital equivalent of driving a car with the Check Engine light on. You know something might be wrong—maybe you’re spending too much, maybe you’re missing sales—but you don’t have the diagnostic tool to figure it out.

If you are spending more than $1,000 a month on ads, flying blind isn’t just risky; it’s expensive. According to a study by WordStream, the average small business wastes up to 76% of their Google Ads budget on non-converting, junk clicks. That is money that could be funding a new hire, a new product run, or a holiday bonus.

Performing a comprehensive audit isn’t just about finding errors; it’s about uncovering opportunity. Whether you’re taking over a new account or trying to optimize your own, this guide will walk you through how to audit a Google Ads account to turn a leaky bucket into a high-performance engine.

Let’s pop the hood.

The Foundation Check – Account Structure and Settings

Before we look at the flashy stuff (like ad copy), we have to check the foundation. A house built on sand will collapse, and a Google Ads account built without structure will burn through cash.

The Nesting Doll Principle
Google Ads operates on a hierarchy: Account > Campaigns > Ad Groups > Keywords/Ads. A healthy account mirrors a well-organized toolbox. If you have one campaign with 50 ad groups and 500 keywords all jumbled together, your ads won’t be relevant to the search query, and Google punishes irrelevance with high costs.

What to look for during your audit:

1. Campaign Purpose: Are the campaigns split by goal? For example, a “Branded Search” campaign should be separate from a “Generic Search” campaign. If they are together, you are likely overpaying for people searching for your name.
2. Geographic Targeting: Check the Locations tab. Are you serving ads in a different country or state where you don’t operate? This is a common budget leak. Exclude areas where you can’t do business.
3. Ad Schedule: Is the account running 24/7? If your business only answers phones from 9 AM to 5 PM, but you run ads at 2 AM, you are paying for clicks from night owls who can’t convert until morning (if they remember you at all).

Action Step: Ensure your account utilizes at least a Search Campaign and a Display/Remarketing Campaign separately. Mixing them is like using a fishing rod and a net at the same time—you lose control of what you catch.

The Keyword Scalpel – Separating Performance from Waste

Now we get to the heart of the audit: the keywords. This is where that 76% waste statistic usually lives.

Most struggling accounts use Broad Match keywords like a shotgun, hoping to hit something. A healthy account uses match types like a sniper.

The Audit Checklist for Keywords:

• Search Terms Report: This is the holy grail. Go to Keywords > Search Terms. This shows you the exact words people typed in that triggered your ad. You will likely find surprises.
  • Example: If you sell Men’s Leather Boots but you see someone clicked your ad after searching for how to repair leather boots, that’s a waste of money.
• Negative Keywords: Are you using them? If the Search Terms Report shows irrelevant queries, they must be added as Negative Keywords to stop future waste.
• The “Skyscraper” Check: Look at your keywords. Are your highest spend keywords also your highest converting? If Keyword A costs $50 per click but makes $500, and Keyword B costs $40 per click and makes $0, Keyword B is the problem, not the budget.

Pro Tip: Look for close variants. Google often matches ads to misspelled words. Ensure those misspellings are actually relevant to your business.

If you find that your local campaigns are being triggered by national searches, you might need a more granular strategy. Check out our specialized approach for localized targeting at Digital Marketing Agency to refine that focus.

Ad Copy & Extensions – The Art of the Click

You’ve fixed the targeting. Now, does your ad actually make people want to click? And more importantly, does it tell them exactly what they get?

According to Google, businesses see an average 10-15% increase in click-through rates simply by adding ad extensions. If your account isn’t using extensions, you are leaving money on the table.

Auditing the Creative:

1. Relevance Check: Does the ad headline include the keyword? If someone searches for cheap plumbing service, and your headline says Plumbing Services, it’s okay. If it says About Our Company, it’s terrible.
2. The Extension Audit:
   • Sitelinks: Are you linking to specific pages (Contact Us, Sale Page, Service Menu) or just the homepage?
   • Callouts: Are you listing unique selling points? (e.g., 24/7 Service, Free Quote, Licensed).
   • Call Extensions: Is your phone number visible on mobile?
3. Responsive Search Ads (RSAs): Are your RSAs actually filled out? I often see accounts with only 3 headlines and 2 descriptions out of a possible 15. Google needs assets to mix and match to find the winner.

Landing Pages – The Great Converter (or Silencer)

Imagine shouting the best sales pitch in the world through a megaphone, but when the customer walks up to your door, it’s locked. That is a great ad sending traffic to a bad landing page.

Google knows if your page is good or not. They measure this via Quality Score. A low Quality Score (1-3) means you pay more per click. A high Quality Score (7-10) means you pay less.

How to audit your post-click experience:

• The One-Question Test: Look at your top 5 keywords. Now click the ads. Does the landing page immediately answer the query of that keyword? If I click Blue Women’s Running Shoes, I better be on a page with Blue Women’s Running Shoes, not the Women’s Shoes category page where I have to filter myself.
• Mobile Friendliness: Over 60% of searches happen on mobile. Zoom in on your phone. Can you read the text? Is the “Buy Now” button the size of a pea? If yes, users will bounce.
• Conversion Tracking: This is the biggest sin in PPC. If you aren’t tracking conversions (form fills, calls, purchases), you are flying blind. Check to see if the conversion tag is installed on the “Thank You” page. If it’s on the homepage, it’s tracking visits, not sales.

If your audit reveals that your digital storefront isn’t converting visitors, you need to bridge the gap between the click and the customer.

The Numbers Game – Conversion Tracking & ROI

Finally, we look at the bottom line. In the world of how to audit a Google Ads account, this is the final exam.

Open up the Conversions column. If you see 0 for a campaign that has been running for 30 days, you are in a danger zone. You are paying for traffic with no idea what that traffic does.

Key Metrics to analyze:

• Conversion Rate: Is it above 3%? Below 1%? A low conversion rate suggests either the wrong traffic or a broken website.
• Cost Per Conversion: Is this number lower than your profit margin? If you sell a $100 item, and it costs you $120 in ads to get a sale, you have a mathematical problem that no amount of brand awareness can fix (unless you have a massive upsell strategy).
• Impression Share: Are you missing out on potential traffic due to budget? If your Impression Share is low (e.g., 20%), it means you only show up for 1 in 5 searches. You might need to increase budget or improve Quality Score to compete.

Sometimes, the data shows that your local visibility is great, but your national reach is suffering. Depending on your business goals, you might need to double down on the strategy that works best. For hyper-local results, see how we structure campaigns at Digital Marketing Agency.

Conclusion: The Check Engine Light is Off

Auditing your Google Ads account isn’t a one-time event; it’s a routine maintenance check. By stripping away the bad keywords, tightening your location settings, and ensuring your ads match your landing pages, you stop burning cash and start building a predictable revenue channel.

Key Takeaways:

1. Structure is King: Separate campaigns by goal.
2. Waste is the Enemy: Use Search Term Reports to add negative keywords weekly.
3. Relevance Rules: Your ad must match the keyword, and the landing page must match the ad.
4. Track or Die: If you aren’t tracking conversions, you aren’t running ads; you’re gambling.

Don’t let another month go by hoping for the best. Take 90 minutes this week to run this audit. If you find yourself overwhelmed by the data or simply don’t have the time to play mechanic, let’s talk.
