Every contractor knows their website "could be better." Few realize what it's actually costing them in lost revenue every month.
Here's the math, broken down line by line, with a simple calculator you can run on your own numbers.
The bad-website calculator
Three inputs decide what your website is costing you in lost jobs every month:
Bad-Website Cost Formula:
(Monthly visitors × conversion gap × close rate × average ticket) = monthly lost revenue
Input 1: Monthly website visitors
Check Google Analytics or your site's hosting dashboard. Most small contractors get 50-500/month from organic + ads.
Input 2: Conversion gap
An optimized contractor website (loads in <3s, mobile-first, click-to-call, 3-field form) converts 10-15% of visitors into leads.
A typical bad contractor website converts 1-3%.
The gap is usually 8-12 percentage points. Use 10% as the default.
Input 3: Close rate × ticket size
If you close 30% of leads at a $1,500 average ticket, every lead is worth ~$450.
Worked example: small roofer
- 200 monthly visitors
- Converting at 2% = 4 leads/month
- Should be converting at 12% = 24 leads/month
- Gap = 20 leads/month
- 20 leads × 30% close × $4,500 ticket = $27,000/month in lost revenue
That's $324,000/year leaking out of a slow, ugly, mobile-broken website. The website itself is the bottleneck — not the traffic.
The 5 things that turn a bad website into a converting one
- Speed — under 3 seconds on mobile (Google PageSpeed score 70+)
- Mobile-first — 70% of contractor traffic is mobile, design for mobile first
- Click-to-call — sticky button that follows the user as they scroll
- Real reviews above the fold — embedded Google reviews, not fake testimonials
- One-step quote form — name, phone, what you need. That's it.

How to test your own website in 10 minutes
- Speed: run it through pagespeed.web.dev. Mobile score should be 70+.
- Mobile: open it on your phone. Can you tap the phone number? Are buttons big enough? Does the menu work?
- Above the fold: on mobile, without scrolling, can you see (a) what you do, (b) where you serve, (c) phone number, (d) quote button?
- Form: count the fields. Anything over 4 is too many.
- Reviews: are real Google reviews embedded with real names and dates?
Fail 2 or more = your website is the bottleneck.
The bottom line
Most contractors blame "bad traffic" or "the market" when their website doesn't book jobs. The truth is usually that the website is broken in 2-3 specific ways that are easy to fix.
If your website is failing the audit, the fix is to either pay $5k-$15k for a custom rebuild — or use a done-for-you contractor template that has the 5 elements baked in.
Double G includes a built-for-you contractor website (loads fast, mobile-first, embedded reviews, click-to-call, short quote form) as part of our $297/month all-in stack — alongside missed call text-back, AI receptionist, review funnel, and GBP optimization.
