Website performance

DESCRIPTION

A slower website can significantly impact your revenue. Studies show that every second of delay can lead to a notable drop in traffic: 1 second equals a 2.8% revenue loss, while 2 seconds can mean a 4.3% decline. Companies like Shopzilla have seen dramatic improvements by reducing load times from 6 seconds to 1.2 seconds. Faster page speeds result in more repeat visits, page views, and conversions, leading to higher revenues and user satisfaction. Focus on optimizing your front-end to enhance performance and business outcomes.
