How to do a PPC audit the right way (process + examples)

As an inherently lazy person who considers acting like a potato a viable lifestyle choice, I don’t like having to revisit things I consider vetted, tested, checked off, and done. Those operations should be running flawlessly in the background, without needing me as a babysitter. All. I want to do is eat a Cup-o-Noodles and binge watch Homicide: Life on the Street for the thousandth time. 

But if you work in paid media the way I do, you know this a fever-dream delusion. Because, at some point, we all face the same situation.

Your PPC campaign is “technically” running. 

Spend is moving, dashboards are full, and members of your team are saying things like:

“Sure, performance is mixed, but it’s directionally encouraging.”

But your gut is starting to get mouthy. Directionally encouraging? Whatever you say, Bob. That’s like saying if I get within 5 feet of my ever-growing laundry pile, that’s “directionally encouraging.” But my laundry still isn’t getting done, folks.

So, deep down, you know something is off. But what?

Maybe costs are creeping. Maybe conversion volume is flat. Maybe the account is full of campaigns no one has questioned in months. Maybe the agency keeps handing you polished updates and numbers that still somehow never add up to anything remotely positive. Maybe the whole thing has started to feel like a machine that is always in motion and rarely under control.

This is the moment when you need a down-and-dirty, ol’ fashioned PPC audit.

Is it glamorous? Of course not. 

No one’s ever busted into a conference room with the enthusiasm of Lin-Manuel Miranda, who’s ready to declare to the world that he’s not giving away his shot, screaming: “Great news, everybody! We get to review search query quality and conversion settings in our campaigns! Let’s! Get! Pumped!”

Still, a well-executed PPC audit does something extremely useful: it forces the truth to come out. And the truth is your starting point for making smart decisions.

It tells you what’s working, what’s pretending to work, what’s quietly wasting money, what’s being measured badly, what’s over-credited, what’s under-managed, and where the account has drifted into lazy habits nobody wants to admit are lazy habits.

That is the real point of the audit.

Instead of generating giant checklists, building 40-page slide decks full of screenshots and color-coded urgency levels, or creating the appearance of rigor while avoiding any meaningful judgment, a PPC audit should help you answer a much simpler question:

If we had to justify every dollar in this account from scratch, what would survive?

That’s the only question that matters. 

First, what is a PPC audit? (the real definition)

The most basic definition is this: a PPC audit is a structured review of your paid media account to figure out how it is actually performing, how it’s set up, and where the biggest problems and opportunities are.

Obvious, yes. And it’s also where a lot of marketing teams start pumping the brakes, because they treat it like a housekeeping exercise. You’re not only checking whether or not the naming conventions are tidy and the conversion tags still exist — and then immediately declaring the account healthy. 

Of course, you’re going to look at performance. 

But you’re also going to look at the logic behind the decision-making driving your performance.

You do that by asking questions like:

• Why is the account structured this way?
• Why is budget going there?
• Why are these campaigns still alive?
• Why are these keywords broad?
• Why is this audience stack here?
• Why are these creative assets still running?
• Why is this conversion action the optimization target?
• Why does this report say one thing while the business feels another?

When you’re willing to ask these questions and look at the answers you find with honesty, you’re doing something useful.

And this holds true whether you’re managing your PPC campaigns in-house or working with a PPC agency. These are the kinds of questions that make people feel uncomfortable. No one wants to have their work come under such a high degree of scrutiny. No one wants to be the reason something is failing. And, in some cases, there are definitely people who don’t want their low efforts to come to light. 

But still, ask you must. Because in many cases, your campaigns and accounts aren’t broken. They might be bloated, over-automated, under-questioned, or still built around old assumptions. In those cases, no one is at “fault.” You might be where you are simply because something that worked a few months ago needs to be refined so it will work right now. 

When you actually need a PPC audit

OK, so let’s start by saying you shouldn’t wait until everything is on fire, and your job is already on the line to do a PPC audit. Just like you wouldn’t ask your roommate if they smell something burning in the oven while a paramedic is treating you for smoke inhalation in the back of an ambulance.

Even though we know this, we still wait. 

We still hope for the turnaround. 

We still hope that whatever’s broken will unbreak itself.

Then, your hand gets forced.

Typically, we see brands call for an audit when costs rise fast, conversion quality drops, scaling gets weird, results flatten, a new agency takes over, a bad agency gets fired, leadership starts asking harder questions, or everyone has been staring at the same account for so long that nobody can tell the difference between “this is strategic” and “this is just how we’ve always done it.”

Now, I’ll be the first to admit those are all very valid reasons to say: “Hey, uh, we should probably take a look at what’s actually going on.”

But the best time to do a PPC audit is before the pain becomes obvious. Once the pain is obvious, you are usually already paying for it.

If performance has gotten noisier, if reporting has gotten more flattering than useful, if the account is relying heavily on automation and nobody can cleanly explain where the value is coming from, or if the same campaigns have been running with only minor tweaks for months, you probably need an audit.

You may not have a total disaster on your hands, it may just be drift. 

But hoo boy, is drift expensive. It’s like a slow bleed.

What your PPC audit should include

I don’t care if you’re running your own PPC campaigns or working with an agency. Anyone can say they’re doing a “PPC audit,” but not everyone is operating off of the same set of rigorous standards. 

So, when we talk about PPC audits here, we’re talking about a comprehensive paid account assessment across four key categories:

• Business alignment
• Account structure
• Performance quality
• Measurement processes and standards

🔎 Go deeper: Landing page optimization strategies to increase conversions (a practical, data-driven guide)

Business alignment comes first because the account should be serving a business, not just chasing platform-friendly numbers.

So, start by making sure you’re clear on the goal:

• New customer acquisition?
• Margin?
• Revenue volume?
• Lead quality?
• Inventory movement?
• Market expansion?
• LTV-rich customer growth?

If the business goal is fuzzy, the audit is going to get fuzzy too.

Then you look at structure.

Specifically, you ask:

• How are campaigns organized?
• Does the structure match the actual strategy, or is it just an inherited pile of campaigns from three different eras of account management?
• Are budgets being allocated intentionally?
• Are branded and non-brand campaigns separated cleanly?
• Are remarketing and prospecting actually distinct?
• Are Shopping, Performance Max, search, paid social, and display playing clear roles, or are they all wandering around the same room stepping on each other’s lines?

Next, you look at performance quality. But looking at surface metrics doesn’t count. Looking at CTR, CPC, and ROAS in a vacuum doesn’t count either. You want to understand what kind of performance the account is actually producing:

• Are conversions good? Is traffic relevant?
• Are campaigns being over-credited?
• Is branded demand making everything look smarter than it is?
• Is there real incrementality?
• Are creative assets fatiguing?
• Are search queries messy?
• Are audiences too broad, too narrow, or simply stale?

Finally, you turn your Eye of Sauron to measurement. This is where a shocking amount of nonsense hides:

• Are the right conversion actions being used?
• Are campaigns optimizing toward the metric the business actually cares about?
• Is attribution giving a useful story or a flattering one?
• Are there duplicate conversions, weak signals, lag problems, or platform setups that make the account look better than the actual business feels?

If the measurement is wrong, everything downstream gets weird.

The PPC audit process (or how to actually do it)

The easiest way to do a PPC audit well is to stop thinking of it as one giant task and treat it like a sequence of sharper questions.

Step 1: Start with the business, not the dashboard

We covered this in detail in the last section, so it should come as no surprise that this is where we’re starting.

What does success mean to your business? How do you define it? Is this account supposed to maximize efficient revenue? Find new customers? Protect margin? Scale volume even if efficiency softens a bit? Support product launches? Clear inventory? 

This is where you start. Because if you don’t know what success is supposed to look like, in data-driven detail, you won’t be able to tell if something is broken. 

This is also where you need to get honest about what the business can actually afford. A campaign can have a lovely in-platform return and still be bad for the business once margin, discounts, returns, or customer quality enter the chat.

So start there. What is PPC supposed to do, and what kind of result actually counts?

Step 2: Review structure like a skeptic, not a curator

Once you are in the account, look at structure with a mildly suspicious attitude.

Don’t only look for evidence that everyone’s smart choices are still holding up, so no one’s feelingts get hurt.

And don’t assume the structure is intentional just because it exists.

Even nonsense can be arranged to look coherent, and old logic will still look logical on the surface while still being woefully out of date.

A lot of PPC accounts are layered with old campaigns, old tests, old naming logic, old audience ideas, old keyword groupings, and old automation decisions that no one ever cleaned up because they were too busy “optimizing.”

🔎 Go deeper: How to analyze keywords for effective ad campaigns

So, this is when you need to start asking some annoying questions:

• Why are these campaigns separate?
• Why are these ad groups built this way?
• Why is this campaign limited by budget while that one is not?
• Why are these match types still here?
• Why is branded traffic sharing space with non-brand?
• Why is remarketing bundled into broader efforts that make performance harder to read?
• Why are there three campaigns that seem to be doing versions of the same thing?

Again, this isn’t glamorous work, but it’s important work. And sure, these questions may feel uncomfortable at first. Still, you’ve gotta do it. You’ve gotta dig and dig and dig. Bad structure creates bad interpretation, and then it becomes harder to see what is really happening, harder to control spend, and easier for weak performance to hide inside the clutter.

Step 3: Check search quality, audience quality, and traffic quality

Next, it’s time to dig into the actual quality of what the account is buying.

For search, that means looking at search terms, not just keywords. The keyword list may look “strategic” while the actual queries tell a much uglier story. You want to know whether the account is attracting relevant intent or just paying for loosely related curiosity. This is especially important if broad match and automation have gotten cozy and everyone is pretending that’s the same thing as precision.

Step 4: Audit the creative like it matters, because it does

A lot of PPC audits underplay creative, which is ridiculous.

Just like we eat with our eyes first, we shop with our eyes first, too. 

So, of course, creative matters.

If you are auditing paid social, display, video, Performance Max assets, or even search messaging, creative should not be treated like decoration. It is one of the main levers of performance, and weak creative can make the account look like it has a targeting or bidding problem when the real issue is that the messaging is stale, generic, or completely disconnected from the actual customer hesitation.

So look at what has been running:

• For how long?
• Against which audiences?
• With what variation?
• What’s clearly fatiguing?
• What’s pulling attention but not converting?
• What’s converting but at a cost that suggests it is doing too much heavy lifting?
• What has strong engagement but weak business outcome?
• What’s being refreshed, and what’s just being rotated around like leftovers?

A good audit does not just say, “creative should be tested more.” That is obvious and useless. It should tell you what kind of creative problem the account has.

Step 5: Review conversion setup and optimization logic

This is the part people underestimate, then regret underestimating.

You need to know exactly what the campaigns are optimizing toward and whether that thing deserves the power it has been given.

🔎 Go deeper: 5 key reasons to take advantage of A/B testing

Since I’m a predictable gal, you know I’m now about to drop a bunch of questions to you need to ask on you. Just let it happen:

• Are campaigns bidding toward purchases, leads, qualified leads, add-to-carts, page views, some Frankenstein combination of those, or something else entirely?
• Are micro-conversions helping you learn, or are they making the account overconfident about weak intent?
• Are primary conversions set correctly?
• Is duplicate counting muddying the waters?
• Are platform goals aligned with business goals, or is the account optimizing to the metric most likely to make reporting look pleasant?

You should always ask these types. of questions, but they’re especially important if you’re running accounts in automated environments. If you’re building automations off of bad data and signals, it’s going to be very efficient… at chasing the wrong thing.

That’s how you end up in uncomfortable meetings where everyone’s pointing at how “performance looked so strong,” but your business needs are unmet.

Step 6: Look for wasted spend like you are paying the bill personally

OK, folks, break out your wallets. It’s time to talk about the money of it all.

And I meant what I said in that heading right above — I want you to pretend like this is your money. Because we don’t mind when someone else is picking up the check for dinner, right? But we get a little line-item happy when Billy decides he wants a fifth old fashioned.

So, look at your PPC accounts with that kind of scrutiny. 

Where is money being wasted?

It could look like:

• Search terms that are too broad
  
• Campaigns spending against weak intent
  
• Branded traffic soaking up credit
  
• Remarketing audiences with too much overlap
  
• Budget going to stale creative
  
• Products or categories that simply do not justify the spend they are receiving
  
• Too many campaigns chasing the same user at different points with no clear coordination
  
• Geographic targeting, devices, placements, or time periods that have not earned the money they are getting

I need you to be eagle-eyed and scrupulous in your judgment when auditing the money, because your account will almost never label the problem for you in a neat little box called Money We’re Wasting Over Here.

You have to infer, compare, challenge assumptions, and notice where spend has become habitual instead of strategic.

Here’s a simple PPC audit example

Let’s say you audit an ecommerce Google Ads account and at first glance it looks healthy. ROAS is acceptable. Conversion volume is stable. Spend is moving. The weekly reporting has a nice, adult tone.

Then you look closer. 

And all of the leaks in your PPC account become clear:

• Branded search is doing a huge amount of the work, which makes the account look cleaner than it really is.
• Performance Max is taking generous credit for conversions, but product-level margin tells a rougher story.
• Search terms on non-brand campaigns are broader and sloppier than the keyword strategy suggests.
• Shopping is spending nicely on some lower-priority products because the feed is not segmented tightly enough.
• Remarketing is layered into multiple places, so the same warm user is getting chased around by half the account.
• The conversion setup is optimizing toward a purchase event that counts all orders equally, even though not all orders are equally valuable.

Yikes.

This account is being flattered by branded demand, automation is being trusted a little too much, and budget allocation is not tightly aligned with business value. But hey, also lots of opportunity to tighten things up and move toward the results you want… rather than just floating in the purgatory of “directionally encouraging.”

What a good PPC audit should give you at the end

You should walk away from a good PPC audit with priorities and an action plan. 

So, if your PPC audit (or the one your agency does for you) results in oblique observations, or 47 pages of “categorized” notes with no clear hierarchy, congratulations! You’re now the proud owner of documented, marginally organized confusion.

Your audit should tell you clearly:

• Here are the top structural issues.
• Here are the biggest measurement problems.
• Here’s where spend is leaking.
• Here’s what should be paused, split, cleaned up, refreshed, or redefined.
• Here’s what is actually working and deserves protection.
• Here’s what looks like performance but is mostly credit capture.
• Here’s what needs immediate attention
• Here’s what can wait.

That’s useful data. That’s a well-defined roadmap of what you need to do next.
