It’s no secret that slow loading pages mean you’re missing out on hundreds of sales. In fact, research carried out by KISSmetrics, reports that for every one-second delay in page load speed, your conversions will drop 7%. So for an average store generating $50k per month, that could mean $42k in lost revenue per year. But the bigger the store, the bigger the potential losses, just add another zero to those numbers and the losses look scary.

Even as far back as 2006, Amazon reported that for every 100 milliseconds they sped up their website, they saw a 1% increase in revenue. But since 2006, the average attention span of a web visitor has plummeted to just 8-seconds, so if your page loads in over 4-seconds, you have just 4-seconds left to impress them enough to stay and buy.

So what if you could slash 2-seconds off your load times? That would mean a potential 20% increase in revenue, based on Amazon’s findings.

Or you could see results similar to a more recent study by The Performance Beacon, who found pages that load just 1-second faster, experience a 27% increase in conversions.
