What a fast website actually saves you per month
Page speed isn’t a vanity metric. It’s a direct revenue lever. Here’s the napkin math for a typical HVAC company.
A typical HVAC website we audit loads in 4.7 seconds on mobile. Industry research says you lose roughly 1 in 3 visitors for every additional second of load time past 2 seconds. So a 4.7-second site is losing somewhere in the neighborhood of 35-45% of visitors before the page even renders.
The napkin math
Say you’re running $5,000/mo in Google Ads at a $24 cost-per-click. That’s 208 clicks per month landing on your site. If 40% bounce before the page renders, you’re effectively paying for 83 visits you’ll never see.
At $24/click, that’s $1,992 per month thrown away before any of your other marketing even gets a chance to work.
What the fix actually involves
A fast site isn’t magic. It’s:
- Static HTML (no WordPress, no plugins)
- Modern image formats (AVIF/WebP) with responsive sizes
- A CDN that serves from the visitor’s nearest data center
- No third-party scripts beyond what’s strictly necessary
- A simple, semantic markup tree
We build every Eureka site this way. The result is a Lighthouse score above 95 on mobile, which translates into a sub-2-second load time on the median connection.
If you’re paying for ads and your site loads slowly, the ROI of fixing the site is almost always higher than the ROI of buying more ads.
