How many seconds before you lose the mobile customer
In 2026, the average website takes 8.6 seconds to load on mobile, versus 2.5 seconds on desktop. Mobile now makes up over half of all web traffic, so that number isn't a technical footnote: it's half of every business's visitors.

What each second costs
Every extra second of load time costs a business roughly 7% in conversion, and on mobile specifically that runs closer to 12%. 53% of mobile visitors abandon a site that takes more than three seconds to appear. They never get to read the price or the phone number, they're gone before that.
The other side of it
Sites that load in under two seconds convert at 2.4 times the rate of ones that take five seconds or more. And the improvement doesn't have to be dramatic: shaving off even a tenth of a second has measurably lifted conversion in retail and travel sites.
For a service business, the math is simple: if someone's searching "plumber near me" on their phone with an emergency, those first three seconds decide whether they see that business's number or the next result's.
