Image optimization in online businesses is primarily evaluated by its impact on website performance and user experience. Key technical metrics include Page Load Time (especially for pages with many images) and Google's Core Web Vitals, particularly Largest Contentful Paint (LCP), which directly measures the loading performance of the largest element, often an image. Another vital metric is the average image file size reduction, indicating efficiency, alongside server response time improvement due to lighter assets. From a business perspective, successful optimization leads to a decreased bounce rate, increased conversion rates on product pages, and improved SEO rankings due to faster loading speeds. Additionally, businesses monitor bandwidth cost savings and overall customer satisfaction, as a smooth visual experience directly contributes to a positive brand perception.
