I audited a window installation business recently. Beautiful website. Clean design. Good copywriting. They were getting 40-50 website visits a month. Their form was converting at about 5% — so 2-3 enquiries per month.
But here's what I discovered: that 5% conversion rate was misleading. The real picture was much worse. And the place the business owner thought the leak was? That wasn't the problem at all.
The Real Leak: Three Hidden Stages You're Not Measuring
Most businesses think "conversion" means "form submission." But there are actually three critical stages before the form:
Stage 1: Click to Correct Page
Someone clicks your Google Ad (or finds you organically). Do they land on a page that matches what they're looking for?
Stage 2: Page to Interested Visitor
They land on the page. Do they stay? Do they scroll? Or do they leave immediately?
Stage 3: Interested to Form Filler
They're interested. But do they trust you enough to fill out a form with their contact information?
What happened with the window company
The owner was running Facebook ads to their homepage. Sounds reasonable, right? But here's what I found:
- —
Ad 1: "Window Replacement Deal — Save 20%" landed on the homepage (general window products page)
- —
Ad 2: "Bathroom Renovations" also landed on the homepage
- —
Ad 3: "Same-Day Emergency Service" — also homepage
Every ad, no matter the promise, landed on the same generic homepage. Someone clicked the "Window Replacement" ad, got excited to see the deal, and landed on a page that showed... all products, with no specific mention of the 20% deal they were promised.
The Three Leaks
Leak 1: Wrong Landing Page (Stage 1)
The biggest leak was that all ads landed on the homepage. Someone who clicked a specific ad expecting a specific page doesn't find it — so they leave immediately.
The fix: Create dedicated landing pages for each ad. "Window Replacement Deal" ad → dedicated window replacement page. "Emergency Service" ad → emergency service page.
Leak 2: No Form Confirmation (After Submission)
This was the second leak. After someone filled out the form, they got a generic "Thank you" message. Nothing else.
No email confirming their submission. No message saying "Someone from our team will call you within 24 hours." No reassurance that they made the right decision. Just "Thanks. We'll be in touch."
This matters because form-fillers are in an uncertain state: Did it work? Will someone actually call me? Should I call them instead? That uncertainty makes them regret filling out the form.
Leak 3: No Content to Educate or Reassure
The third leak was harder to see but it explained the low conversion rate. The website was nice, but it didn't answer the questions visitors actually have:
How much does it actually cost?
What's involved in the installation process?
How long will it take?
Will my house be a mess during installation?
These questions kept people from filling out the form because they felt like they didn't know enough. A blog post answering these questions would have given them confidence to submit the form.
How to Find Your Leaks
To find where your funnel is actually leaking, you need to measure each stage separately. Here's the test:
Metric 1: Ad Click-Through Rate (CTR)
If CTR is low, the problem is your ad copy or targeting. If it's normal (2-5%), move to metric 2.
Metric 2: Landing Page Bounce Rate
In Google Analytics, check the bounce rate for your ad landing page. Above 60%? People are leaving immediately. The page doesn't match the ad promise.
Metric 3: Form Submission Rate
Of people who land on your page, what % actually fill out the form? If it's below 3%, something about the page (trust, unclear CTA, too long form) is blocking submissions.
Metric 4: Post-Submission Engagement
After they submit, do they get a confirmation email? Do they get a follow-up message? If not, you're losing leads after they've already committed.
The Results
For the window company, we fixed all three leaks:
Created dedicated landing pages for each ad
Added a confirmation email after form submission
Created a blog post answering common questions about window installation
Conversion rate went from 5% (2-3 leads/month) to 12% (5-6 leads/month). Same ad spend. Same traffic volume. Just fixed the leaks.
