Your Marketing Doesn't Have a Strategy Problem. It Has a Plumbing Problem.

Most businesses that aren't getting results from their marketing assume they need a better strategy. They don't. They need to check the plumbing.

Every few months, a business owner tells us the same story. They hired an agency. Approved the ads. Set the budget. Six months later, the results are stubbornly average. So they change the strategy. New creative. Different targeting. Maybe a new agency altogether. Still average.

Nobody checked the plumbing. Not the ads, not the offer, not the creative direction. The invisible infrastructure underneath everything: the conversion tracking configuration, the form design, the call duration threshold, the page speed, the review velocity. Settings somebody chose once, probably during setup, and never revisited.

Broken plumbing doesn't announce itself. It just quietly makes every strategy look worse than it is.

The $300 Million Button

Jared Spool documented a case study about a major e-commerce site that required account registration before purchase. Standard practice. Every competitor did it.

The problem: 45% of shoppers had created multiple accounts because they'd forgotten their passwords. The site processed 160,000 password reset requests per day. And 75% of people who clicked "reset password" never completed their purchase.

The fix wasn't a new marketing strategy. It wasn't better ads or smarter targeting. Someone changed a single button from "Register" to "Continue" and added guest checkout.

First month: $15 million in additional revenue. First year: $300 million.

Rory Sutherland calls these psychological moonshots: trivial changes that produce outsized results because they remove friction nobody was measuring. His eleventh rule of alchemy is "dare to be trivial." It's the rule most businesses ignore entirely.

The register-to-continue change cost nothing. It required no strategic rethinking. It was a plumbing fix. And it was worth more than every campaign that site had ever run, combined.

29% of Google Ads Accounts Are Running Blind

Nearly a third of businesses paying for Google Ads have no conversion tracking firing at all. They're paying for clicks and measuring nothing.

It gets worse. Standard Google Ads conversion tracking now misses 30-50% of actual conversions thanks to cookie restrictions, Safari's Intelligent Tracking Prevention, and ad blockers affecting 30%+ of desktop traffic. You might have tracking configured and still only see half the picture.

This isn't a strategy problem. It's a plumbing problem. And it has cascading effects that most businesses never trace back to the source.

Google's Smart Bidding needs data to learn. Google recommends 30 conversions in the past 30 days before switching to Target ROAS. If your tracking misses half of what's actually happening, the algorithm optimises on a distorted signal. It's not just that you can't see your results. The system learning how to spend your money can't see them either.

One analysis found that 68% of Enhanced Conversions implementations capture incomplete or incorrectly formatted data. Even businesses that set up tracking often set it up wrong.

We see this regularly. One client's call tracking was set to Google's default 60-second threshold. Over 30 days: zero call conversions reported, while phone-click tracking showed 40 actual calls were happening. The calls were real. They were converting. Smart Bidding just couldn't see them because most calls resolved in under 60 seconds.

Change the threshold to 30 seconds and suddenly the algorithm has data to work with. That's not a creative problem or a targeting problem. It's a number in a settings panel. We've written about how your cheapest leads can be the most expensive ones, and misconfigured tracking is often the root cause.

The 80% You're Not Looking At

Sam Tomlinson, whose newsletter The Digital Download draws from hundreds of ad account reviews, puts it bluntly: "80%+ of the results you see in Ads Manager are directly or indirectly influenced by stuff outside the ad account."

His breakdown of what actually drives a purchase decision:

The other 90% is plumbing. The landing page experience. The form. The page speed. The reviews a prospect reads before calling. The follow-up speed after they submit an enquiry. The phone experience when they call.

We've written before about how your marketing results were decided before you wrote a single ad. Tomlinson's data gives that observation specific numbers. The strategy might be brilliant. If the plumbing underneath it can't carry the water, it doesn't matter.

Five Plumbing Failures That Look Like Strategy Failures

Here's what makes plumbing problems dangerous: they present as something else entirely. The symptom looks strategic. The cause is mechanical.

Your form asks too many questions

HubSpot analysed over 40,000 customer landing pages and found that forms with 3 fields convert at roughly 25%. Each additional field drops conversion by about 4.1%. Imagescape documented a 120% increase in form completions simply by cutting an enquiry form from 11 fields to 4.

This is the most common plumbing failure we see. A business adds "Company Name" and "Job Title" to a form because the sales team wants qualification data up front. Conversions drop 15-20%. Nobody connects the two events. The agency gets blamed for declining performance.

The fix: ask for name, phone, email. Get everything else on the follow-up call. Your form is already talking people out of converting. Don't give it more ammunition.

Your page loads in 4 seconds

Deloitte and Google studied 30 million user sessions across 37 brands and found that a 0.1-second improvement in site speed produced measurable results across every sector:

Most businesses don't know their actual page speed. They assume it's fine because it loads quickly on office Wi-Fi. Test it from a mobile phone on 4G in a suburban area, which is how most of your customers experience it.

Your call tracking counts the wrong things

Google Ads has two types of call conversion actions: Calls from ads (someone taps the phone number in the ad itself) and Website calls (someone clicks the phone number on your landing page after clicking through an ad).

Most businesses only set up one. If you only track calls from ads, you're invisible to every customer who clicks through to your website and then calls. Smart Bidding can't optimise for an event it can't see.

Then there's the threshold problem. If you set the minimum call duration to 60 seconds, every call that resolves in 45 seconds gets excluded from your conversion data. Including perfectly good leads who knew exactly what they wanted. Your reporting says "no conversions." Your phone is ringing.

Your reviews stopped flowing

Review velocity has grown approximately 47% year-over-year as a local ranking signal. Businesses earning 4+ new reviews per month ranked 34% higher in the local pack than businesses with higher total volume but sporadic patterns.

A business with 50 reviews and steady monthly growth can outrank a competitor with 200 reviews and no recent activity. Your business has a signal strength problem if reviews arrive sporadically. The businesses that maintain review velocity have a system: every completed job triggers a review request. It's automated. It runs in the background. The ones without a system rely on customers remembering, which almost none of them do.

Your conversion tracking doesn't match your business

The most expensive plumbing failure is tracking the wrong conversion entirely. A trades business tracking form submissions as their primary conversion when 80% of their actual customers call first. A B2B company tracking "Contact Us" fills when their real sales path starts from a downloadable guide.

When you tell Google to optimise for form submissions, it finds people who fill in forms. Those might not be the people who become customers. If your real customers call, and you're not tracking calls as a primary conversion, you're training the algorithm to find the wrong audience entirely.

Why Businesses Fix Strategy Instead of Plumbing

There's a psychological reason businesses default to strategy changes when results disappoint.

Rory Sutherland identifies it: "The fatal issue is that logic always gets you to exactly the same place as your competitors." Strategy feels substantive. Changing your targeting, your creative, your offer feels like a real decision made by smart people. Checking whether your conversion tag is firing correctly feels like admin.

This is what Sutherland calls the physical fallacy: the instinct to prefer expensive, visible solutions over cheap, invisible ones. He uses the Eurostar example. Engineers spent $6 billion building new tracks to shorten the London-to-Paris journey by 40 minutes. The cheaper solution? Install Wi-Fi so passengers could work during the journey. Change the experience, not the infrastructure.

Businesses do exactly this with marketing. They rebuild the campaign when they should have checked the conversion tag. They hire a new agency when they should have fixed the landing page speed. They redesign the website when they should have shortened the form.

Because plumbing problems are invisible, the strategy changes sometimes appear to work. A new campaign with fresh creative gets a temporary lift. But the same plumbing problems drag it back to the same mediocre baseline within weeks. So the cycle repeats.

As Avinash Kaushik frames it in his KPI accountability hierarchy, this is the difference between activity metrics and outcome metrics. Changing strategy produces a flurry of activity. Fixing plumbing produces outcomes. The dashboard shows activity. The bank account shows outcomes.

What This Means for Your Business

Before you change your marketing strategy, audit your plumbing.

Every one of these checks is free. Every one of them has a measurable impact on your marketing results. And every one of them is more likely to be the source of your underperformance than your campaign strategy.

The most expensive marketing problem isn't a bad strategy. It's good strategy flowing through broken plumbing.
