This is the one that makes everyone sweat.
You're in the final round of the interview. The hiring manager says, "Okay, great. Now we're going to send you a link to one of our dummy ad accounts.
Take 15 minutes, look around, and then tell us what's wrong and how you'd fix it.
This is not a test of your technical skills. They know you know what a campaign is.
This is a live-fire test of your `thought process`. It's a test to see if you're a "rookie" or a "pro.
Rookie Approach
The rookie panics. They click randomly. They open the first ad set, look at the CPC, and say, "Well, this CPC is high.
" They have no structure. They get lost in the weeds and offer a list of disconnected "fixes.
Pro Approach
The pro is calm. They don't even open a campaign for the first five minutes. They have a framework.
They know that a good audit isn't about finding one broken thing; it's about diagnosing the `entire system`, from top to bottom.
This `5-step framework` is your structure. It's your diagnostic checklist. Use it every single time.
Before you look at a single metric, you must ask questions. You cannot diagnose a patient until you know their symptoms.
* •`What is the goal of this account? ` Is it generating cheap leads (CPL) or profitable sales (ROAS)? • `What is the target?
` What is a "good" CPL? What is a "profitable" ROAS? • `What is the offer and product?
` Is it a $10 ebook or a $1,000 course?
You cannot say a $50 CAC is "bad" until you know the product is a $20 ebook. Context is everything. Asking these questions first immediately proves you're a strategist, not just a button-pusher.
Now you open the account. Don't look at ads yet. Look at the architecture.
Is this a "messy closet" or an organized system?
* •`Are naming conventions clear? ` Can you tell what's in a campaign just by its name (e. g.
, "Meta - TOF - US - Interests")? Or is it a mess of "Campaign 1\Test\v2"? • `Is the funnel logical?
` Are they separating their "cold" prospecting campaigns (Top of Funnel - TOF) from their "hot" retargeting campaigns (Bottom of Funnel - BOF)? • `Are budgets split smartly? ` Are they spending all their money trying to convert cold traffic (expensive) and ignoring their abandoned cart visitors (cheap)?
Now you look at the ad level. You're diagnosing the first half of the user's journey: from seeing the ad to clicking it. The only metric that matters here is `CTR (Click-Through Rate)`.
* •`The Diagnosis`: Is the CTR on Meta above 1%? Is it above 3% on Google? • If CTR is low (e.
g. , 0. 5%): You've found the problem.
The ads are the bottleneck. The creative is boring, the hook is weak, or the copy doesn't match the audience. The audience isn't "bad"; the message is.
Now you look at the second half of the journey: from clicking the ad to buying the product. The key metric here is `CVR (Conversion Rate)`.
* •`The Diagnosis`: Is the CVR above 2%? (This is a general benchmark; it varies by industry). • If CVR is low (e.
g. , 0. 5%): You've found the problem.
The ads are working (high CTR), but the landing page is failing. This is a "leaky bucket. " You should check for a mismatch between the ad's promise and the landing page's headline.
Finally, you check if you can even trust any of the data you're seeing.
* •`The Diagnosis`: Is conversion tracking properly set up? Are they using UTMs to see where traffic is coming from? • `If tracking is broken`: This is the most critical insight of all.
You can't fix what you can't measure. Your first recommendation isn't to "change the ads"; it's to "`fix the tracking`. " This single insight can be the one that gets you the job.
The Takeaway
Follow these five steps, in this exact order. You will sound like a seasoned professional: clear, logical, and strategic. You'll give them a full-system diagnosis, not just a random "fix.
