Images take up over 60% of modern websites’ total bandwidth. In the case of cutting-edge, image-rich designs, such as those for social media like Pinterest, that number is, remarkably, over 85%.
Bandwidth is a costly commodity that gobbles up most of the IT budget of high-traffic sites, easily surpassing hosting and storage costs. In addition, because the sheer volume of traffic takes time to consume, your visitors often spend a lot of time waiting for images to load.
Given the astronomical IT outlay, visitor abandonment due to lengthy load times, and the subsequent reduction in conversion rate and revenue, do make it a high priority to optimize your websites images and speed up their delivery.
