The Number Nobody Likes to Look At
If you have Google Analytics on your site, you probably have a bounce rate. And if your site is running on older infrastructure, that number might make you uncomfortable.
Bounce rate is the percentage of visitors who land on your site and leave without clicking anything. A high bounce rate isn’t always a problem. Sometimes people find what they need on the first page. But often, especially on mobile, it’s telling you something simpler. Your site was too slow. They left.
What the Research Says
Google’s benchmark research on mobile load time put hard numbers on this, and the numbers have held up for years. As page load goes from 1 second to 3 seconds, the probability of a visitor bouncing climbs 32%. From 1 second to 5 seconds, it jumps 90%. By 10 seconds, the odds of losing that visitor run over 120% higher than a fast site. And some older WordPress sites still hit 10 seconds on a mobile connection.
That’s not a typo. The compounding effect is that dramatic.
What This Means in Real Numbers
Say 500 people visit your site this month. If it loads in 4 seconds instead of 1, you might be losing 50-100 of them before they read a word. If even 10% of those would have become leads, that’s 5-10 lost contacts. Every month. For as long as your site stays slow.
The Fix Is Usually Simpler Than It Sounds
For most small business sites, faster load times run through the same place. A lighter, more modern architecture. No database queries on every load. No plugin stack, no heavy page builder rendering each time someone shows up.
We’ve been watching this play out in real numbers across our migration work this year. The improvement isn’t marginal. It’s often dramatic.
