How to Spot a Broken PPC Funnel in 30 Seconds on Google

Right, let's cut through the nonsense. You don't need a PhD in data science or a fancy dashboard that costs more than your monthly ad spend to spot when your PPC funnel is completely broken. In fact, if you can't identify major issues within 30 seconds of logging into Google Ads, you're probably overthinking it.

Most ecommerce managers spend ages staring at vanity metrics like impressions and CTR whilst their actual profit signals are screaming from the SERP. Time to stop ignoring the obvious red flags and start looking at what actually matters.

The 30-Second Reality Check Method

Here's the harsh truth: a broken PPC funnel announces itself faster than a Karen demanding to speak to the manager. You just need to know where to look.

Step 1: Check Your Search Terms Report (10 seconds)

Open your search terms report and scan the top 20 queries. If you see search terms that make you think "why on earth would someone searching for that buy from us?", congratulations - you've found your first leak.

Look for gems like:

• "Free [your product]" when you don't offer anything free

• Competitor brand names triggering your ads

• Generic terms with zero buying intent ("what is [product category]")

Step 2: Campaign Overview Scan (10 seconds)

Navigate to your campaigns tab and look at the conversion rate column. If you see campaigns with conversion rates below 1% that have been running for more than a month, you've got a problem. Don't let anyone tell you "it's industry standard" - that's just code for "we haven't bothered fixing it yet".

Step 3: The Device Performance Quick Check (10 seconds)

Click on "Devices" in the left menu. If your mobile conversion rate is dramatically lower than desktop (we're talking 50%+ difference), your mobile experience is probably terrible. Most agencies will blame this on "mobile user behaviour" rather than admitting your mobile site is slower than a Sunday driver.

Warning Signs That Scream "Broken Funnel"

The Budget Vampire Campaign

You know the one - it's sucking up 40% of your budget but delivering conversions that you could count on one hand. These campaigns usually have one thing in common: they're targeting keywords that sound relevant but attract completely the wrong audience.

Classic example: An outdoor furniture store bidding on "garden furniture" and wondering why they're getting clicks from people looking for dolls' house accessories. The keyword looks right, but the intent is miles off.

The Vanity Metrics Hero

High CTR but zero conversions? Your ads are basically clickbait. You've mastered the art of getting people to click, but your landing page is about as convincing as a chocolate teapot.

This usually happens when your ad copy promises one thing ("50% off everything!") but your landing page delivers something else (a 5% discount on selected clearance items, terms and conditions apply, offer expires yesterday).

The Quality Score Disaster

Quality scores below 5 aren't just "room for improvement" - they're Google's way of telling you that your entire setup is fundamentally flawed. Low quality scores mean you're paying premium prices for bottom-shelf placements.

The Real Profit Signals Your Agency Won't Show You

Forget about the pretty graphs showing impression share growth. Here's what actually indicates a healthy PPC funnel:

Cost Per Acquisition vs Lifetime Value Ratio

If your CPA is approaching your average order value, you're in trouble. A healthy ecommerce funnel should show CPA at roughly 20-30% of AOV, accounting for repeat purchase likelihood.

Return on Ad Spend (ROAS) Consistency

ROAS that jumps around like a kangaroo on Red Bull indicates targeting issues. Consistent performance across similar time periods suggests your funnel is actually working, not just getting lucky.

Search Impression Share for Brand Terms

If you're not dominating your own brand searches, you've got bigger problems than funnel optimisation. Your competitors are literally stealing customers who already know your name.

Common Funnel Breaks and Quick Fixes

The Landing Page Mismatch

Your Google Shopping ad shows a blue widget, but clicking through lands on a page featuring red widgets. Seems obvious, but you'd be amazed how often this happens, especially with large product catalogues.

Quick fix: Run a 5-minute audit of your top-performing product ads. Click through and check if the landing page matches the ad promise.

The Checkout Abandonment Black Hole

High click-through rates and solid landing page metrics, but conversions drop off a cliff during checkout. Usually caused by surprise shipping costs, mandatory account creation, or a checkout process longer than a Tolstoy novel.

Quick fix: Complete a purchase on your own site using your mobile phone. Time how long it takes and count how many steps are involved. If it's more than 3 steps or takes longer than 2 minutes, that's your problem right there.

The Keyword Cannibalisation Catastrophe

Multiple campaigns bidding on similar keywords, driving up your own costs whilst confusing Google about which ad to show. It's like having your sales team compete against each other instead of against the competition.

Quick fix: Search for your main product keywords and see if multiple ads from your account appear. If they do, you're bidding against yourself.

Beyond the 30-Second Spot Check

Once you've identified the obvious issues, it's worth diving deeper into the data. But remember, if you can't spot major problems in 30 seconds, you're probably overcomplicating things.

The best PPC audits start with common sense, not complex formulas. If something looks wrong at first glance, it probably is wrong. Don't let anyone convince you that obvious problems require sophisticated analysis to identify.

Using Google's Native Tools

Google Ads provides all the diagnostic tools you need for this rapid assessment. The Recommendations tab, while sometimes suggesting questionable "optimisations", can highlight genuine technical issues like disapproved ads or broken tracking.

The Auction Insights report shows you exactly who you're competing against and whether you're losing impression share to competitors with deeper pockets or better-optimised accounts.

The Attribution Reality Check

Last-click attribution might show certain campaigns as "unprofitable", but that doesn't mean they're broken. However, if a campaign shows zero assisted conversions AND zero direct conversions, it's probably not contributing to your funnel at all.

What Comes Next?

Spotting broken elements in 30 seconds is just the beginning. The real work starts with systematic fixing, testing, and optimisation. But at least now you know where to look instead of getting lost in vanity metrics that don't impact your bottom line.

Remember, a truly broken PPC funnel announces itself loudly. If you need complex analysis to identify major issues, they probably aren't that major. Focus on the obvious problems first - you'll be surprised how much improvement comes from fixing the basics.

The goal isn't perfection; it's profitability. And profitable PPC funnels have one thing in common: they convert visitors into customers at a rate that makes business sense. Everything else is just noise.
