Why does performance matter?

Put simply: slow sites deter visitors, costing conversions

Every 100ms faster → 1% more conversions

For Mobify, every 100ms decrease in homepage load speed worked out to a 1.11% increase in session-based conversion, yielding an average annual revenue increase of nearly $380,000.

50% faster → 12% more sales

When AutoAnything reduced page load time by half, they saw a boost of 12% to 13% in sales.

20% faster → 10% more conversions

Retailer Furniture Village audited their site speed and developed a plan to address the problems they found, leading to a 20% reduction in page load time and a 10% increase in conversion rate.

40% faster → 15% more signups

Pinterest reduced perceived wait times by 40% and this increased search engine traffic and sign-ups by 15%.

850ms faster → 7% more conversions

1 seconds slowness → 10% less users

The BBC found they lost an additional 10% of users for every additional second their site took to load.
